  • MarsRoadtrip Part 5: CSAtweetup

    Made it back the next morning only a few minutes late (for which I am rather impressed with myself, running on 2.5 hours sleep and not being able to remember/find what time I was supposed to get there), and settled in for another awesome day of spacey goodness!

    We started off with Gilles Leclerc, Director General of Space Exploration, welcoming us and giving an overview of the Canadian Space Agency and what all it’s up to! CSA is a small agency, with around 700 employees and an annual budget of only $250 million. (Curiosity cost about 10 times that!) But – by partnering with other/larger space agencies (Canada is the only non-European cooperating member country of the ESA… Austrialia is probably jealous!), and keeping focused on specific areas of expertise (especially robotics and small science satellites, rather than developing their own launch vehicle), CSA is able to make significant contributions and maintain a major presence in the space industry, maximizing the bang for their buck!

    Next, we had a special surprise call-in guest – Astronaut David Saint-Jacques (@Astro_DavidS)! He was actually on vacation with his family, but was kind enough to interrupt his vacation and take some time out to chat with us spacetweeps over Skype! Very nice guy! He’s an engineer, medical doctor, astrophysicist, and commercially licensed pilot, who was selected as part of the 20th Astronaut class in 2009, and is currently stationed in Houston, awaiting his turn in space! When asked what the hardest part of being an astronaut is, he said it was maintaining balance – not totally geeking out over how cool it is and completely losing yourself in your job! I bet! (And he hasn’t even been to space yet! Just wait…) 😀 The best part is the people you work with. 🙂

    Then it was tour time! The first stop was the Space Technologies Lab – an area with a bunch of cleanrooms where they develop and assemble small satellites and such (sensitive work that they did not want photographed… tweeting was okay though!) Favorite factoid from this bit of the day was that satellites in Low Earth Orbit can turn themselves using electromagnets and the Earth’s magnetic field! (But satellites in geo-stationary orbits can’t, because they’re too far out and the magnetic field isn’t strong enough out there!)

    In the Space and Planetary Sciences Lab, we saw the Earth version of MSL’s Alpha Particle X-Ray Spectrometer (APXS)! (Which, my brain actually absorbed this time, takes in small soil samples and analyzes the contents for evidence of past – or maybe even present – life on Mars!) This version is briefcase-sized, while the one on Curiosity is about the size of a Rubik’s Cube, because the one they sent to space needed to be as compact and lightweight as possible, but without launch restrictions, this only needed to be portable enough for people to carry so they were able to make it larger and more powerful for faster results! (They take it out to test a variety of samples on Earth, to which they’ll compare the results we get from Mars!)

    Visiting Research Fellow, Pablo Sobron Sanchez, explains the APXS (Earth edition)!

    Curiosity has a limited number of “clean samples” it can take – it only has 24 containers, which can be reused, but residue from earlier tests may contaminate the new sample, giving less accurate results – so they have to be somewhat selective with the samples they take. To decide where they most want to test, they’ll use data from the other MSL instruments and cameras, as well as images we’re already getting from various orbiters. All of those images are actually available on the internet for anyone to look at, and if you’re so inclined, to study and do science with!

    Next, we met Operations Engineer Mario Ciaramicoli, in a massive sort of split-level garage-y-type robotics lab with a whole lot going on! The upper part of the room was dominated by a full-scale engineering model of the Canadarm2, which is currently in service on the International Space Station. (Its predecessor served aboard and retired with the space shuttles – Endeavour’s Canadarm recently returned to Canada and is chillin’ in the lobby!)

    Canadarm2 is a couple meters longer than the original, has an extra joint and greater rotation in all of its joints, and was designed so that its joint motors and computers and such can be replaced on orbit for much simpler repairs and maintenance. However, the coolest part, to me, is that it doesn’t have one fixed “shoulder” end, with the “hand” opposite – rather, it has identical ends that can both attach to the station or go off and be the working end, or even trade roles back and forth, with the acting “hand” grappling onto the station somewhere else, the “shoulder” releasing and becoming the hand, and so on, to “walk” around the station for greater access! It can also connect with Dextre, the smaller two-armed robot, for more complicated work that would otherwise require an astronaut to go EVA, but can instead be done by the robot, controlled from inside the station!

    We got to see the Mission Control room from which Canadarm2 and Dextre operations on ISS are supported, as well as the simulator where all the engineers, astronauts/cosmonauts, and mission/flight controllers who will be involved with using the arm come for training before they can be certified as robotics operators, and go on to more specific training for their particular missions!

    A major part of Mario’s job is preparing the new programming for missions… basically every time they use the arm, they have to write a new program to operate the arm! For tasks similar to ones they’ve done before, it’s pretty simple to just update the numbers for component masses and other parameters, but for something totally new, they have to pretty much start from scratch, and it takes months and months of programming and running simulations to verify it will do what they tell it to when they try it for real in space! Craziness!

    Sweet ISS mural!

    Our last destination for the morning was the exhibit hall, where they have models of a bunch of Canadian satellites and other projects Canada contributed to. Senior Engineer Marie-Josée Potvin gave us the rundown of all the ones present, and also stuck around to eat lunch with us!

    This model of RADARSAT-1 is actually hanging over the main lobby, but there’s another smaller of the same in with the rest!

    Marie-Josée explains SCISAT (actual size!) monitors the ozone by sucking some in through a small hole on the underside (not that big one – it radiates heat)

    After lunch, it was rover time! We heard from the folks in the Exploration Development and Operations Centre, where they’re working on the infrastructure to monitor/support/control robotic exploration missions from the ground. They decided to go with workstations around the perimeter of the room and a large table in the center, for a more collaboration-friendly layout for the control room than the traditional rows of consoles – you’re monitoring your station, discover something that needs discussion and a decision, so you can just turn around to confer with your team at the table, and then go back and do your thing! (Makes sense to me!)

    We paused in the Rover Integration Facility (read: giant rover garage/workshop) on our way outside, and saw a variety of components and rovers, including a Jeep-sized one with seats that can be driven remotely, as a robotic explorer, but could also be used for manned exploration in the future!

    Outside, we discovered the Analogue Terrain – a big field of sand and gravel with various inclines and heaps of rocks, approximating a variety of ground conditions similar to those one might encounter on Mars or the moon! And boy were we glad it was a nice day out (gorgeous, in fact), because ROVERS! Two of them were out playing in their big sandbox – okay, engineers with RC controllers were calling the shots, but ROVERS!

    They drove them around a while and showed us the nifty things they could do to get around better, and we checked out the mobile version of the remote operations center.

    Then, at some point, I look back over and the rovers are coming over to visit! Turned out, they were going to be part of the group for our group picture! We got to check them out up-close-and-personal, and I even got to hug one! (Yes, I’m a nerd. We know this. But ROVERS! For machines, they’re adorable!)

    Eventually we headed back inside to hear about the Artic Expedition that engineering grad student Raymond Francis (@CosmicRaymond) took part in earlier this summer, to determine whether a certain very large hole in the ground on Victoria Island was, in fact, an impact crater! It was an especially exciting and successful expedition, because they not only confirmed that it is and impact crater, but also found it’s basically a really good one (to study), because it has excellent examples of geological features only found in impact craters and… general geological interesting-ness. (My brain was kind of overflowing at this point, so pardon the particulars not quite sticking.) Besides the geologists one would logically send on this sort of expedition, the team also included Canadian astronaut Jeremy Hansen, who is not a geologist – they were training him in the basics of conducting a geological survey (I think… pretty much), so when he’s hypothetically off exploring some other planet, he’ll know what to look for to take photos or samples of that will be interesting for geologists back home to study! Neat!

    We ended the day with Jean-Claude Piedboeuf, Director of Space Exploration Development, discussing the future of space exploration in general, and of course Canada’s in particular! The near future is obviously going to be humans sticking to the ISS while we learn more about the effects of living in space long-term, and robots doing the planetary exploration. More long-term, as you might expect, we want to get to Mars, and back to the moon, but in what order, and whether or not to throw a station at the Lagrange Point between Earth and the Moon into the mix or not depends who you ask! I can’t wait to see what happens… 🙂

    As we were “leaving” (which bore a striking resemblance to “not leaving,” as we just kept pausing and chatting!) I discovered that @Colin_H_Hart goes to Ursinus College, which is 14 miles from my office! (Plus, he happens to currently living in Cleveland, where I had also just come from.) Funny how that happens… going to another country and meeting someone from basically back home! Small world. 🙂 Turns out we were also staying in the same hotel, and he was car-less, so I gave him a lift back, and he introduced me to a deli he’d discovered around the corner that makes very tasty sandwiches!

    Headed back to the hotel, ate, watched the Curiosity press conference and popped into the Twitter for a bit, and then sleep deprivation punched me in the face and I went to bed pretty early. In the morning I packed up, checked out, and began the long drive back.

    The long drive back

    It was actually only about 45 minutes to the border heading straight south (as opposed to the couple hours meandering east along the Canadian side of the border my route coming from Ohio had taken), but then I sat in traffic/line for probably a solid hour waiting to get through the immigration checkpoint. (There had only been one other car in sight at the little boondocksy crossing I’d come in through!) When I did get up to the booth, I thought it was hilarious that the guy asked exactly the same questions as the one who let me in had – not just the obvious “Where are you from?” and “What are you doing in Canada?” but when I answer that with “Going to an event at the Canadian Space Agency,” they both responded, “Are you some kind of engineer or something?” What? Nobody but engineers ever goes to the CSA? 😛 Guess they never heard of tweetups!

    The next few hours were boring, but pretty… way-upstate New York is pretty much mountains and trees and not much else. (Not even proper food at the rest-stops, just vending machines!) Other than being a bit hungry by the time I got back to civilization, it was a nice drive! And then my GPS stopped cooperating just as I got new NYC, so I missed the exit I needed and accidentally took a little detour to the Bronx, and got turned around in some sketchy part of New Jersey trying to find my way back to a road that would take me to PA. (Anywhere in PA, just get me out of Jersey!) Eventually made it back to the Garden State Parkway, which at least went in the general direction of things I know.

    After a little while, I saw a reststop had really cheap gas, so I went to stop and fill up… only right as I got on the exit ramp, I felt a thump that made me pretty sure I’d just gotten a flat tire. The service station was right there anyway, so I rolled over at a crawl, and asked the attendant to look at it… turned out it was not only flat, but had shredded! GONE. Lovely.

    Now, I’m perfectly capable of changing my own tire, but I’d been driving for about 10 hours at this point and feeling lost in freakin’ Jersey for the last while, so I was at my wit’s end, and the attendant said he’d help me change it if I could wait a few minutes, so I did. It took a little longer than I would have liked, but he came back over, hauled the spare out of its hole in the back of my car… and said he’d be back again in a few more minutes. I was tired, so I figured whatever, and waited. After rather a long while, I wondered where the hell he’d gotten to, and asked one of the other guys pumping gas… who said the guy’d left! Jackass!

    None of the rest of them seemed inclined to help me out, and by this point I was too tired and flippin’ angry to think straight, much less figure out the stupid jack, so I tried calling AAA – but apparently New Jersey won’t let them on certain roads, so they had to transfer me to some NJ highway something. I was just about to get them to send somebody out, when some random guy getting gas saw me on the phone and staring at my retard car looking like I wanted to kill something mechanical – “I know that look,” he said – and asked me if I wanted help. I gladly accepted, he swapped the tire-less wheel for the donut in about 3 minutes, made sure it had air, and reminded me not to go too fast on it and to pay it forward. I assured him I wouldn’t and would, respectively, thanked him profusely, finally got that cheap gas, and limped off home at 45mph with Marian Call’s “From Alaska” disc (my new comfort/sanity music) on repeat!

    Despite a mildly craptacular ending, it was an awesome trip! I had expected to be pretty exhausted and sick of driving after all that, but seems even 6 days away, 1700 miles, and a blown tire didn’t wear out my roadtrip love!

    Thanks to the lovely folks at NASA Glenn and the Canadian Space Agency for your hospitality, and to everybody behind Curiosity and NASA and CSA in general for doing awesome things for us spacetweeps to geek out over! I am so excited for all Curiosity’s pictures and science over the next two (and hopefully several more) years! Happy roving! 🙂

  • MarsRoadtrip Part 4: Dare Mighty Things

    It is a very strange feeling to drive to a government building – in a foreign country – in the middle of the night. Felt slightly mischievous, but the security guard didn’t seem to mind! Magalie led me to the press auditorium, where I found a familiar face (@datachick) and an even more familar view – a NASAtv view of a mission control room projected up on a screen!

    JPL Mission Control
    The traditional launch peanuts

    We heard a bit about the APXS, Canada’s contribution to Curiosity’s assortment of science instruments, from Director of Space Exploration Projects Stéphane Desjardins (the fellow on the right), but it was hard to pay attention to much other than the feed from JPL when we were just minutes away from Curiosity’s actual “7 minutes of terror!” – which, by the way, if you haven’t seen the “trailer” yet, seriously, go watch it immediately. Or better yet… here:

    Schrödinger’s Rover

    Mars is far away (in case you didn’t know 😛 ). So far, in fact, as they mentioned in the video, that even traveling the speed of light, signals take 14 minutes to reach earth. It was kind of nutty (besides the traditional peanuts being passed around mission control) knowing the little rover actually was on Mars for seven minutes before we even heard she’d entered the atmosphere… we knew she’d reach the surface around 1:17am (Eastern), but we wouldn’t find out whether she had landed safely or crashed until 1:31! Eep!

    So 14 minutes delayed, JPL narrated Curiosity’s Entry, Descent, and Landing. Heartbeat tones, cruise stage separation, more heartbeat tones, entry interface, guided entry bank reversals, ballast jettison, parachute deploy (applause), wrist mode nominal, heat shield separation, back shell separation, powered flight, standing by for skycrane, skycrane has started (cheers), “Tango Delta Nominal,” touchdown confirmed – and the room exploded in applause, cheers, hugs, tears, and high-fives! Curiosity landed safely on Mars!!!!!!!!

    All the emotions! (Photo Credit: NASA/JPL-Caltech)

    It was perfect. Curiosity went exactly where she was supposed to go, arrived at Mars right on course, the crazy/brilliant EDL sequence went exactly how it was supposed to, the Odyssey orbiter was exactly where they hoped it would be to relay data all the way down, and Curiosity was safe and happy as pie on the surface of freaking Mars, very close to the center of the target landing zone, and communicating right away! Woohoooo!!!

    And all of like 30 seconds later… “We got thumbnails!”

    One of the rear hazcams sent a 64×64 pixel thumbnail photo showing one of the wheels and the horizon of Mars! Seriously, it’s been 30 years since anybody was that excited about a thumbnail image! (But hey, it was entirely probable they wouldn’t get any images for at least 2 hours, and we started seeing them just minutes after landing, so they/we are allowed to be excited!

    It was quickly followed by the full 256×256 version, showing a wheel and the Martian horizon as clearly as the dusty dust cover would allow… and then another shot from another hazcam – this one showing Curiosity’s shadow!

    Bill Nye when Curiosity landed
    We tweeps at the CSA, along with the team at JPL, and I’m sure space nerds round the world, clapped and cheered, and clapped and cheered some more, as a Mini-Cooper-sized spacecraft-turned-roving-science-lab plopped onto another world, and promptly sent back a handful of tiny black and white photos of dirt. And we were never so excited to see dirt. BECAUSE IT’S MARS DIRT. AND CURIOSITY IS ALIVE AND SAFE AND AWESOME.

    =)

    Eventually the broadcast ended and we left to go get a bit of sleep before the rest of the tweetup! After some coffee with the security guards and a nice man with a crow bar resolving the slight glitch of my keys being locked in my car, I made it back to my hotel and somehow managed to get unconscious for a couple hours.

  • MarsRoadtrip Part 3: More Driving

    The GPS once again proves itself retarded.

    As I was leaving the restaurant, I remembered I needed to get gas, so I poked the “Gas Station” button on the GPS and followed its lead… but the place it took me was not a gas station… looked more like an airport rental car place, so it probably did have gasoline, just not any to share with me.

    So I tried again… and this one didn’t even vaguely resemble a gas station!

    No longer trusting the gorram gizmo, I looked at the map of all the places it was claiming were gas stations, and saw that two of them were on the same road. I figured at least one of them had to actually be for real, so headed that direction. I arrived at the first one, and lo and behold, an actual-factual gas station! Slightly shifty and deserted-looking, but a gas station nonetheless, so I pull in and go to get some gas… but there isn’t any. The pumps were on and functioning, there just wasn’t anything to pump. -_-

    So I got back in and continued on to the next place, which finally actually had gasoline for my sad little car. Filled up, got back in, punched in my uncle’s address, and headed out.

    Of course, instead of taking me back to where I’d gotten off the highway near Glenn, it took me further into Cleveland (pretty much the opposite direction of where I really wanted to go, only I didn’t realize that for a while) and I never quite figured out what it had in mind, because when it got me back near anything resembling a highway, half the turns it wanted me to make were blocked off for construction!

    Eventually, no thanks to the GPS, I found my way to a road pointed in the general direction of my uncle’s and found my way back. Oy!

    [Insert sleep here.]

    To Canada!

    The following morning, I loaded up and headed off again, Canada-bound! About 11 hours on the road… not much to report! I-90 is long. (And boring. Thank goodness for audiobooks! (Or really, just the one since it turned out to be really long!)) Followed it along Lake Erie for the rest of Ohio, through the weird little nub of Pennsylvania, and into New York. I thought about detouring to Niagara Falls, but decided it was gonna be a long enough day already without a 2 hour side trip, so just kept on I-90 over to Syracuse, and then 81 up to Canada!

    For some reason, they let me in 🙂 so I kept going! It was kind of wacky to see everything marked in kilometers and kph… luckily they also included miles for the first while for us silly southerners. Soon every sign in sight was in French, and it really started to feel like I was in another country! (Which is kind of hilarious, because in the grand scheme of Canada, I was barely over the border!)

    By the time I was driving through Montreal on the “Autoroute Transcanadienne” it was dark, and the moon was hanging low and huge and gorgeous, right in front of my face, honestly the biggest and deepest colored I’ve ever seen it… it kind of felt more like another planet than another country!

    At long last, I made it to my hotel, (assured the girl at the desk I had not, in fact, cancelled my reservation,) got to my room, showered, and crashed! Nice room, comfy bed, epic sleep.

    I didn’t have to arrive at the Canadian Space Agency for the first installment of the CSA tweetup and Curiosity’s landing until midnight Sunday night/Monday morning, so I slept in Sunday and it was delicious.

    I thought about going into Montreal to explore/sightsee, but couldn’t figure out what I wanted to see, and figured with my luck with the GPS lately, I’d spend most of the day lost, and I was still pretty beat, so I just hung out at the hotel for the day, watching the only thing on TV that wasn’t the Olympics or in French (or the Olympics in French) – which turned out to be “Say Yes to the Dress” and then “Toddlers in Tiaras”… so, not terribly interesting, but addictive in a train-wreck sort of way – and tweeting and reading and generally relaxing!

  • MarsRoadtrip Part 2: NASA Social

    I made it to my uncle’s house in Akron without incident. My spine was definitely sick of that car seat by the time I got there, but it was not a bad drive! It did, however, seem like the entirety of both the PA and Ohio turnpikes were marked as construction zones, with only 2 patches actually undergoing any construction… o_0 So I was happy to get there, go out for a late-ish dinner (Mexican!) with my aunt and uncle and cousins and then head for bed before too long. Of course, we all know you can’t get proper sleep the night before a tweetup/social, but being horizontal and reading until I eventually dozed off for a couple hours sufficed! Then there were alarm clocks, coffee, and sunlight (in that order) and I was off to Cleveland!

    NASA Social @ Glenn Research Center

    A slightly frantic arrival, in typical “me” fashion, because (though I left on time) I didn’t see the meeting point, and took a little detour through GRC’s parking lot before finding my way across the highway to actual registration, but I made it just in the nick of time! On the bus heading to the briefing center (back across the road where I’d just been!), I discovered that @KelleyApril was also present, by way of a tweet saying she’d seen me arrive! (Funny thing, being sufficiently busy between work and planning a fairly last-minute tweetup/Social trip that I missed most of the Twitter/Facebook chatter about who was going to be at which Socials, so neither of us knew that the other’d be there!)

    Anyways!

    GRC’s Center Director, Ray Lugo, welcomed us with a couple of fun facts I didn’t know about Curiosity, including:

    • Before coming to Glenn, he had worked as the Launch Services Program Director at KSC, and was actually the person who selected the Atlas V rocket as the launch vehicle for Curiosity! That seems to have worked out pretty well. 🙂
    • The rover was named by a then-6th-grader from Kansas, Clara Ma, who submitted the winning contest entry – Curiosity!

    (He got to head out to JPL for the landing… “Perks of being Center Director!”)

    Then we got a brief hello from STS-134 astronaut Greg Johnson, also known as @Astro_Box! I was hoping he’d stick around for a while so I could say hi and maybe get a picture with him, since I got to watch his launch from so delightfully close! But when he asked if anybody had any questions, I couldn’t think of an actual question (my brain was slightly overloaded with excitement!) …and apparently nobody else could either! Unfortunately, by the time I realized it was now or never, he had surmised nobody had any questions, and had another event to get to, so I never got the chance to properly meet him! 🙁 It was still very cool that he took the time to stop by though! (and take/tweet a quick picture!)

    We had a few minutes to mingle and check out some of the exhibits in the lobby, and then we were off on a whirlwind tour of Glenn Research Center! – which is painfully punny, since my group’s first stop was at the 10×10 Supersonic Wind Tunnel (which just means the test section is 10ft high and 10ft wide, and uses compressors and the shape of the tunnel rather than just big fans to get the air flowing faster)! It was cool to see another wind tunnel after visiting Langley Research Center in the fall, where we saw their transonic wind tunnel, which operates right around the speed of sound – whereas this supersonic one typically runs at 2-3 times the speed of sound – and that one was cryogenic (they could cool the air for more accurate testing on small-scale models), while here they can heat the air to test how air flows in jet engines or during atmospheric entry! (As they did for one of the initial parachute deployment tests for Curiosity!) 😀

    The coolest part was we got to go inside the test section, since it wasn’t in use at the moment. It was all very, very, smooth metal, because any little glitch in the surface would create a sonic line or somesuch and throw off the results! Also very nifty: they can change the contour of the walls leading into the test section, with a serious of giant hydraulic jacks that could actually move the 1.5inch thick stainless steel walls in or out by several feet, with a ridiculous degree of accuracy! So neat!

    Next we were off to a Physical Sensors Instrumentation Research lab, where they are working on developing more heat-tolerant sensors to for detecting pressure, light, certain chemicals, or whatever else in jet engine tests and other high-temperature environments. Normal sensors use silicon-based chips, but apparently silicon can only withstand temperatures up to 200 or 250 degrees, and the inside of a jet engine goes upwards of 700 degrees, so that’s not going to cut it! To solve that problem, they’re working on using Silicon Carbide instead, which allows the sensors to keep functioning at much higher temperatures. The process requires certain bits of something to be exposed to UV light and not others (something about polymers that went over my head!), so there are all these storage containers and windows covered in those orange UV filters… and they’re made with microscopic precision, so everything’s done in clean rooms wearing bunny suits!

    Then we saw the Stirling Research Lab‘s “Advanced Stirling Radioisotope Generator” – a power system they’ve developed to provide electricity for future deep space missions, rovers, and satellites! Curiosity runs on a similar nuclear power system, but this one will be much more efficient. (It’s advanced after all! 😛 But seriously.) It’s powered by a little bit of plutonium-238 (which, we are assured, is much more stable than the plutonioum-239 used in nuclear bombs!) producing a lot of heat energy, that the Advanced Stirling Converter converts into usable electricity, with four times the efficiency of current systems. It’s designed to provide power for 17 years, and the test model we saw in the lab has been running nearly continuously for 4 years already.

    There are three proposed missions NASA is currently considering for development, and two of them would use this power system (a “Comet Hopper” and a… well, basically a boat, that would land on one of the methane seas of Titan to study the “water cycle”-like methane weather patterns!) so they’re obviously hoping one of those two gets selected (the other is a Mars lander that would be solar powered) and now, so am I! 🙂
    (UPDATE: The selection has since been made, and they went with the Mars lander. Still awesome, just not as cool as sending a boat to a moon! 😛 )

    The last stop on our tour was to the SLOPE (Simulated Lunar OPErations) Facility – a giant sandbox! It’s full of special sand designed to resemble the surface of the moon (but without the very fine particles that would create epic dust clouds every time anything moved) or Mars to test the traction/behavior of different tire designs and rovers! Awesomes.

    Their goal when the facility was built was to pick up where Apollo folks had left off… they wanted to test the moon buggy tires and go from there, but obviously the ones actually used are still on the moon, and the rest are all sitting in museums somewhere… but they managed to get in touch with one of the guys who designed the tires, and he “just happened to have a spare sitting in his closet at home.” With his help, partnering with Goodyear, they managed to replicate the original design and manufacture 12 new ones, which they did use for research and as a starting point for new designs!

    We got to see/poke/squish/roll a bunch of the designs they’ve been testing, and he drove the prototype rover that was in there around for us! It was really neat… each of the four wheels is on a sort of arm thing, and has its own motor, so they can both drive and position each independently, which makes for some neat tricks! (Including “inchworming” up hills, tilting the rover in relation to the ground incline to keep it level and improve stability, and all sorts of fancy “getting un-stuck” maneuvers!) And I got to pick up a handful of fake moon sand! 😀

    That concluded the tour, and the bus took us over to the cafeteria/employee center for lunch and gift shop time! I had a pretty tasty cheeseburger and fries (which I think is becoming a tradition, since that’s what I ate at Langley, and I’m pretty sure also at KSC during 134), and a lovely chat with a fellow spacetweep who’s a police officer in Wisconsin! That’s one of the things I love about tweetups/socials – hanging out with people with whom you’d probably never even chance to cross paths, much less sit down and have an actual conversation, otherwise!

    After lunch, we headed back to the briefing center where we’d started the day (not the parking lot – after that) for the multi-center portion of this first-in-history Multi-Center Social!

    JPL Social Media Manager Veronica McGregor kicks things off

    It was basically a simulcast, broadcast from JPL to the other 6 centers tweetupping that day (at some point they added a 50th Anniversary social at KSC, conveniently coinciding with the rest!) as well as NASAtv!

    (Oh! Sweet! Turns out it was also streamed on Ustream, which apparently keeps the recording available online for a while! So feel free to skip my rambly bullet points and just watch it for yourself!)

    The program started off with a rapid-fire sequence of presenters, including:

    • A brief welcome from JPL Director Dr. Charles Elachi
    • A recorded message from NASA Administrator Charlie Bolden
    • Deputy Administrator Lori Garver spoke about why we’re going to Mars at all!
    • Dave Lavery, NASA Program Executive for Solar System Exploration, talked the difficulty of landing on Mars.
    • Clara Ma! – no longer eleven – read the essay she wrote to suggest the name Curiosity.
    • Doug Ellison showed us the simulation of Curiosity’s landing on Eyes on the Solar System (check it out!)
    • Stephanie Smith, part of JPL’s social media team (who came to our 134 tweetup and let us hold aerogel!) acted as host/moderator/MC for the panel discussions
    • The science panel – Ashwin Vasavada, of JPL, MSL Deputy Project Scientist; Pam Conrad, from Goddard Spaceflight Center, Deputy Principal Investigator for the Sample Analysis at Mars (SAM) instrument; and Ken Edget, Malin Space Science Systems, Principal Investigator for the Mars Hand Lens Imager (MAHLI – one of the 17 cameras on Curiosity, specifically at the end of the arm) – talked about why they chose to land in Gale Crater (largely the 6mi. high mountain of sedimentary rock at its center) and a bit about what the various cameras and instruments do.
    • The engineering panel – Rob Manning, MSL Flight System Chief Engineer; Adam Steltzner, EDL Phase Lead (@steltzner); Steve Lee, EDL and Surface Ops Engineer (@LeeCuriosity); and Anita Sengupta, EDL and Advanced Technologies Engineer (@Doctor_Astro) – kicked off with the “7 Minutes of Terror” video (which I’m sure most of those present had already seen at least once, but absolutely nobody minded watching again!) and discussed how complex Curiosity and her mission are, learning from and improving on past missions, actually getting to Mars, how they developed the rover and EDL systems, testing the different elements (since they can’t exactly test the whole thing together without being on Mars!), and how (and how soon) we’ll get data and pictures back from Curiosity!
    • A brief “interruption” by Astronaut John Grunsfeld (@SciAstro) just to sort of say hi and how excited he was about this mission!

    …and time for some Q&A with both panels! That’s where it really got “multi-center” – each participating NASA center had a microphone hooked into JPL and the broadcast, so tweeps could ask questions live, regardless of which Social they were physically attending! What was particularly neat to me was how many of the question-askers I had met at prior NASAtweetups! (They’re addictive!) Seriously, I think I knew at least half of the folks who got to ask questions during the broadcast!

    If you’ve ever wanted to see what this NASA Social/tweetup stuff is all about, or love tweetups but couldn’t make this one, or were there and just want to relive its awesomeness, you’re in luck! Almost 2 hours of NASA-y goodness are just a play button away!

    The next and final segment of the NASA Glenn edition of the Curiosity NASA Social featured GRC’s resident Mars Expert, Geoffrey Landis. We had a whole hour to pick his brain, so covered quite the array of topics – everything from how rovers’ landing sites are selected, the weather on Mars, and a ton about Martian geography, to what it’ll take to get a manned mission to Mars, to how the Mars of science fiction relates to non-fictional Mars! As it happens, he has a pretty unique perspective on that last bit – being both a NASA scientist and award-winning sci-fi author! (Definitely going to have to check out his stories!)

    We wrapped up, presented our lovely hosts with a poster signed by the tweeps, and hopped on the buses on last time to head back to our cars. A quick group photo with GRC in the background, and the our NASA Social came to its end… but only officially! Most of us just relocated across the parking lot to the 100th Bomb Group Restaurant for an early dinner and drinks and a few more hours of NASASocializing with our fellow spacetweeps! (Thanks once again to @KelleyApril for organizing!)

  • MarsRoadtrip Part 1: Mars or Bust!

    Two tweetups in one week? Yes please! 😀

    Okay, so technically one was a “Social” – NASA decided to start letting Facebook and Google+ followers in on the #NASAtweetup awesomeness, so they changed the name to #NASASocial – but Canada’s was still #CSAtweetup!

    Two days after Thanksgiving, NASA launched the Mars Science Laboratory (MSL) “Curiosity” rover on an 8.5 month journey to our dusty red neighbor – a journey we knew would end, one way or the other, around quarter after 1am (EDT) Sunday night/Monday morning. In June, as we spacetweeps suspected/hoped, they announced there would be a NASAsocial for the Mars landing, at the Jet Propulsion Laboratory in Pasadena, California (where Curiosity was built)! I registered, of course, but didn’t get selected.

    I don’t know if it was the plan all along, or if they were just overwhelmed by the response, but a couple days later they added 5 more NASAsocials, all at the same time (Friday, August 3rd) at different NASA centers! (The first multi-center NASAsocial!) Soon, the Canadian Space Agency announced they’d have a tweetup too, during the landing and the following day.

    I, of course, registered for everything, figuring I’d probably worn out my welcome/luck by now and wouldn’t get in to any official events, but was fine too since there were epic #RogueTweetup plans in the works…

    But then I got one of those lovely confirmation notices… from Canada! So the question was if I could get my passport renewed in time! …and then, I got ANOTHER confirmation notice, this one from NASA’s Glenn Research Center in Ohio!

    Cue a moment of panic as I tried to decide which I’d rather go to – be part of the first multi-center social, or be in a space agency for the landing itself? (Surely I couldn’t go to both… two tweetups for the same landing?!)

    But then the “Why the heck not?!” sector of my brain kicked in with the realization that this wasn’t exactly trying to be in two places at once (there’s a whole Saturday in between!), and neither NASA nor CSA had said anything to the contrary, so theoretically, I could do both… It was just a matter of sorting the logistics.

    Sorting the logistics

    I looked at flights, but then remembered I’m not quite old enough to make rental cars a viable option, and the thought of trying to mooch rides between airports and hotels and space centers in two different cities (countries!) when I wasn’t sure who I’d know where, plus getting home from the Philly airport at the end (since my family’d be on vacation by the time I got back)… well, it sounded like it would be less exhausting/stressful to just drive!

    A quick consultation with the GoogleyMaps confirmed each leg of the journey would be a full-but-reasonable-day’s drive (about 8/10/8 hours, respectively), and I like driving and traveling alone… plus, I mean, what’s the difference between my typical work day, in which I spend 8 or 9 hours sitting in a chair staring at a screen, and spending those hours sitting in my car staring out the windshield?!

    So I declared it a plan, and surprisingly, though they didn’t see the appeal, neither parent tried very hard to dissuade me. My dad informed me that my uncle’s house is within a reasonable commute to NASA Glenn, so I called him up and made plans to crash there for the first stop, and thanks to recommendations from CSAtweetup’s lovely organizer, Magalie, I found a nice and very reasonably priced hotel near CSA HQ, so I had the “somewhere to sleep” thing covered.

    The only other question mark in this nutty plan was whether I could get my passport renewed in time for Canada to let me in at all, much less to a secure government building… an extra $60 and applying in person will get you a passport pretty quickly, but the earliest available appointment was Monday morning the week I’d be leaving, so I was a bit nervous, but it turns out, the Philadelphia Passport Agency is seriously on their game!

    I wasn’t sure how long it would take me to get there, park, find it, and get through security, so I left plenty of cushion time… and ended up arriving at 9:05, when my appointment wasn’t until 10. Despite warnings that they wouldn’t let you in more than 15 minutes early, and you could be waiting several hours regardless of your appointment time, they let me in right away, checked to make sure I had everything I needed and gave me a number, I waited about half an hour, had my “appointment” (through a bullet-proof ticket window), and was walking back to my car before my scheduled appointment time, assured my passport would be ready to pick up on Wednesday morning! (which it was, and the return visit took all of 3 minutes.) Solidly impressive for government bureaucracy!

    Passport in hand, I *finally* felt free to get excited! I loaded up the iThing with music and audiobooks, threw some clothes and my toothbrush in the car, and roadtripped the heck out of Thursday!

  • Hey look, I found a Tyler!

    That other time we knew each other.
    I haven’t seen this goof in… four years!

    He’s from California (now living in Portland, Oregon), and we met in Minnesota, where we had two weeks training with a organization called CTI, which puts together bands and sends them to do music ministry in various countries for a month!

    So, then his team went to Honduras and mine to Taiwan, and we were all together again briefly at the end, but that was it!

    Thanks to the wonders of the interwebs, vaguely keeping in touch, twitter, facebook, and bloggery, I heard he was planning a cross-country train trip!

    He didn’t end up stopping long in Philly, but he had enough of a layover at 30th Street to meet up and have lunch! What fun!

    Perhaps we should hang out more than once every four years, though, eh?

  • A Tale Told in Tweets – featuring Lisa and John Scalzi

    A day that did not start out particularly well:

    • I was bummed that clouds had kept me from being able to catch a glimpse of the Transit of Venus in person Tuesday night.
    • I was extra upset because I didn’t realize it was the day Enterprise was to be brought by barge to her new home on the Intrepid, and so couldn’t make it up to New York in time to watch!
    • Enterprise was damaged in transit and that made me sad.
    • When our office intern came back with lunch, mine was not what I ordered/wanted, and kind of lame.

    It was just one of those days… but they I saw this tweet:


    https://twitter.com/scalzi/status/210429187503296512

    …One of my favorite authors heading for my city (and terrorizing fellow train-goers)? That has potential. 🙂 So I asked what was bringing him to Philly…


    https://twitter.com/scalzi/status/210430530502664192
    and, of course


    Lisa saw this exchange and expressed envy, which was followed by the following sequence of tweets:

    Me: Cooooome to me! I will bring you to @scalzi!

    Lisa: [this one mysteriously disappeared, but was something along the lines of “Waaah work til 5.”]

    Me: Screw work, leave at 4! Plenty of time then!

    Lisa: …do you think I could make it? With the traffic?

    Me: Yes, the sooner the better, but if you leave by 4, you’ll make it.

    Lisa: I’m in, let’s do this thing.

    !!! *gasp* I seriously never expected her to agree. We play this game a lot. But she’s “responsible” and busy, so she hardly ever goes along with my crazy drop-everything-and-come-hang-out-with-me-schemes! But this time…


    https://twitter.com/PetEditor/status/210462664634286080

    And she did! We both bailed out of work early and converged on a random shopping center parking lot not too far out of the way for either of us, joined forces, and headed downtown! While I drove, she tweeted:


    https://twitter.com/PetEditor/status/210491275626029059

    We found our way to a parking spot, the bookstore, and the little corner of the 3rd floor where Mr. Scalzi was reading a new secret short story. Which was awesome. But secret, so that’s all you get to know about that.

    Then he read an excerpt from Redshirts, which is not secret, because you can buy and read it, but I’m not going to tell you about it, because you should buy and read it!

    The scene he chose to read was chock-full of witty banter, so rather than read the back-and-forth himself, he brought out a surprise special guest!

    https://twitter.com/PetEditor/status/210508265606492162

    This was followed by some seriously entertaining Q&A time, during which he mentioned that there will probably be more books in the Old Man’s War series, which makes me ridiculously happy!

    He talked a bit about his writing process and style, which are both devoid of superfluous details. I hadn’t really noticed as I read his books, but thinking back, you do realize that there’s not a whole lot of description, whether of the characters appearance or their surroundings or whatever, unless its actually relevant to the story. It works for him style-wise, keeping the plot moving rather than lingering amid pages of endless adjectives, but it’s not like he’s leaving things out – it’s not even in his mind. He tends to figure out the particulars only as he needs them, rather than planning everything out in advance.


    He hung around a bit to meet folks and sign books… the bookstore gave half of us panic attacks when they apparently ran out of copies of Redshirts – they thought they had more than that, but couldn’t find them for the longest time! Finally one of them found the other box of books so the rest of us could buy ours and get them signed. Though I had been one of the first few people to get down to the register, I was one spot too far back in line and had to wait for the second batch, so by the time I got my copy and got back upstairs, we ended up being just about the last people to get our books signed. But that was actually okay, because we didn’t feel quite so rushed as those sorts of lines tend to be.

    Scalzi’s good people. (By the way, he blogged this too!)

    So, yay random awesome things happening!


  • Enterprise over NYC

    I drove home from DC on Saturday evening, and Enterprise was scheduled to fly (via SCA) from DC to New York on Wednesday morning, so since I hadn’t really gotten any work done (or even seen my boss in over a week, I figured I should actually go to work for a few days before taking off on another random adventure, and thus figured I’d miss this one…

    But then there was weather, and the ferry flight was pushed to Friday. Still wasn’t planning on going…
    And then, all of a sudden, I was.

    Thursday night, whatever scrap of sanity/restraint I had left snapped, and I bought a bus ticket. @CraftLass was getting a group together to watch the flyby from a pier in Hoboken, so the backdrop would be the New York skyline… and I figured out that I could take the train to the bus station in Philly, the bus to Newark, another train or two to Hoboken, meet up with the spacetweeps, watch the flyby, catch the train(s) back to Newark, bus back to Philly, train home(ish), and drive to the office by 2pm, still getting a solid couple of hours work in.

    It sounded kind of nuts, but apparently I am completely unable to resist once-in-a-lifetime views. So Friday, at the buttcrack of dawn, I was up and off!

    Of course, my brain wasn’t quite functional at that hour, so I was waiting on the wrong side of the train tracks until it was too late and thus missed my train, had to drive like a lunatic to 69th Street Station to get the subway to 30th Street just in time to run to my bus, but I made it!

    The bus even had pretty decent WiFi, so I got to watch the Soyuz landing on NASAtv on my iPad! I figured out the train to Hoboken, which dumped me out right by the pier I was aiming for, found the crew, and waited for Enterprise!

    And she was definitely worth the trip!

    Once again, we happened to be perfectly positioned and she flew right over our heads!

    This is how close she actually was! Not zoomed in at all!

    DSC_0170
    The flew much further on the New Jersey side than we expected, playing peek-a-boo through Hoboken!
    DSC_0174
    Never did line up with the NY skyline… this was as close as we got!

    Another gorgeous flyby! <3 (They'll be bringing her over to the Intrepid by barge sometime over the summer... hope I can make it back up to see that!) It looked like I had a decent amount of time before I needed to head back in the general direction of my bus homeward, so we went to grab some quick food, but between folks getting distracted talking to other shuttlespotters, and slightly misjudging how long it would take me to get back to Newark, I didn't get there in time, and had to daisy-chain transit systems all the way home! Two different PATH trains, NJTransit, SEPTA Regional Rail, SEPTA subway, and a 15 minute drive later, I was home. Unfortunately, it took a couple hours longer than the bus would have, so the still-working-a-half-day plan didn't quite pan out, but I regret nothing! :P :D

    *The STS-134 tweetup began one year ago today! Happy tweetupversary, 134ers!
  • #NASAtweetup #4: @Astro_Ron at HQ

    Much to my surprise, I got into ANOTHER #NASAtweetup! This one, like the first I went to, was a sort of re-cap tweetup at NASA headquarters in DC, this time with Astronaut Ron Garan, recently returned from the International Space Station! (And that one was on my birthday, this one was on Valentine’s Day!)

    It was really interesting to hear about the astronaut experience flying in a Soyuz (especially since that’s the only way to get people to space right now!) and more about living and working on the ISS, being on the station side of a shuttle-ISS meeting, and having his return delayed, delayed more, and then un-delayed… I can’t do it justice… you should probably just look it up on Youtube and watch the tweetup yourself! Or better yet, apply for the next tweetup and go find out first hand!

    But here’s some pictures:

    Another fantastic #NASAtweetup!

    It also was Stephanie Schierholz’ last day as NASA’s Social Media Manager, so they took a moment to honor her. (She’s off to do the same job for a private company, Raytheon!)

    Stephanie Schierholz's last day at NASA

    A lovely gift for @Schierholz

    There were quite a few familiar faces at this tweetup, too!

  • It's official, I live in the future!

    I was in middle school, I think, when I read Ender’s Game and the rest of the series…es (there are two distinct but intertwined storylines in Ender’s universe – one following Ender, the other following Bean). Anyway, the story is set in a future in which exceptionally bright kids are recruited to go to “Battle School” on a space station, to train for a war with an insectoid alien species usually referred to as “Buggers,” but aside from that, everyday life on Earth doesn’t seem to be too different. Besides living in a space station and playing war games in zero gravity, the one thing that stuck in my mind a brilliantly futuristic were the “desks” that everybody had.

    “Desks” were basically small, portable, internet-connected computers with a touch-screen. I remember thinking that was very nearly magical, and pretty much the coolest thing ever. When I was reading that, tablet PCs did exist, but were fairly new still, and bulky, awkward, expensive, and not very powerful. Even laptops were still something I only dreamed about having, the internet was slow and texty, and WiFi (as far as consumers were concerned, anyway) didn’t exist yet. So, this fictional always-connected computer with the form factor of an Etch-a-Sketch became my benchmark for the future.

    And I just got an iPad(2) for Christmas.

    I can take notes, send email, read books, take pictures, draw pictures, watch movies, look up information, play games, and easily access the whole of the internet, any time, anywhere, from this screen thing in my hand, roughly the size of a college-ruled notebook (thinner than an Etch-a-Sketch)! Mission accomplished. Clearly, I am living in the future.

    (Further proof, also based on juvenile fiction: I remember watching the Disney Channel movie “Zenon, Girl of the 21st Century”, and they had little discs that stored data or music or whatever – basically CDs, except they were the size of a quarter. I was storing my school papers on floppy discs, so had a little nerd aneurysm at the thought of fitting all that data on something so tiny… 12 years later, I have a 16gb micro SD card in my phone, full of dozens of CDs-worth of music, a bunch of photos, full TV episodes, and other data, on this little flake of plastic the size of my fingernail. *brainasplode*)
