NASA Astronaut Tom Marshburn ’82 came home to alma mater’s patch of planet Earth this week, after more than five months in early 2013 on the International Space Station. It was a pleasure to shake his hand after having been in touch by phone, email and satellite uplink!
With grace and aplomb, my buddy Tom, the astronaut, gave several presentations on campus, as well as visiting the kudzu goats out by the cross-country trails (see previous post) and otherwise gadding about campus with his daughter Grace and wife Ann, two lovely and delightfully good-humored ladies.
At a Common Hour talk on Tuesday—unofficially subtitled “Bean Dip, Stewed Prunes, ZZ Top and YoYo Ma”—Marshburn spoke of things like translational velocities and parabolic arcs that match the curve of the Earth, by way of explaining the concept of orbital micro-gravity. Then, he recounted how his Soyuz rocket blasted off from Kazakhstan (“like lying on your back in a building that becomes a live animal”) and traveled to an altitude of some 250 miles up, sometimes at speeds of five miles per second. (Yes, per second.)
Next, with plenty of video clips to illustrate, Marshburn recounted some of the “science of opportunity” experiments he and his fellow astronauts and cosmonauts performed with “objects of opportunity” including smuggled vanillin (an ideal viscosity) and duct tape (self-explanatory).
“You start to notice things,” he said. “A lot of our experiments started with ‘Wow, that’s cool,’ and then ‘I wonder what would happen if….’”
• Spinning objects seeking a lower energy state behave differently on their spinning axes depending on whether they are liquid or solid, or both. Application: understanding how fuel tanks affect space flight physics.
• Table salt in a zip-lock bag coalesces in a noticeable pattern at a particular rate. (The grains of sodium chloride are dehydrated from food saline, which is the safety norm on ISS, to prevent weightless grains of salt from flying about willy-nilly at mealtime.) Application: Understanding how the very matter of the primordial universe came together into stars and planets, solar systems and galaxies.
• An Alka-Seltzer tablet dissolves in a huge drop of water big as your fist, in mid-air. Application: Um, I forget exactly, but it is totally cool to look at. In general, weightless liquids in space share some behavioral characteristics with micro-liquids on Earth, particularly in terms of “capillary” flow. Applications range from inkjet printers to HIV diagnostic tools.
At the end of his presentation, when Marshburn’s PowerPoint relinquished the screen to his computer’s desktop, the juxtaposition of astronaut and regular guy came into focus: next to desktop folders marked “Cosmonauts” and “Award Debriefs” were others marked “Invest and Retire” and that old, familiar standby, “Files I Never Use.”
And in the “Launch Pad Tunes” folder? U2’s “It’s a Beautiful Day,” Joe Satriani’s “Summer Song” and Muse, maybe a little “Uprising”?….
Tuesday night, after dinner at the President’s House with classmates, roommates, professors and others, Marshburn gave a public lecture in Duke Family Performance Hall complete with Q&A for the kids of all ages and photo-opps for all at the reception afterward.
Wednesday afternoon, Marshburn made time in his schedule for a visit to College Communications—housed in the college’s Julia Johnston House on Main Street, where he lived upstairs as a sophomore when the building was student housing. He regaled staffers with stories of how he and his housemates cheered, in what is now the office kitchen area, for televised matches of the U.S. Hockey Team in the 1980 Olympics in Lake Placid, New York.
He also regaled us with the story of the “party of the century,” held in the JJ House that year, a costume party with the theme of dressing up as your repressed desire. Already as a 20-year-old, though, he knew his own desire to be an astronaut, and showed up wrapped in tin foil and sporting a borrowed motorcycle helmet….
At a physics seminar hosted Wednesday afternoon by his erstwhile faculty adviser, Richardson Professor of Physics Larry Cain, Marshburn went in to deeper detail about all things physics, for instance radiation (astronauts in space are classified as “radiation workers” and can sometimes see solar protons flashing through their eyeballs). He talked about International Space Station experiments and observations that are adding mightily to the core of human knowledge about nutrition, mental health, osteoporosis, muscle wasting, fish and plants, microencapulation, antimattter, dark matter and “strangelets.”
As luck would have it, Marshburn’s fellow astronaut, Mike Hopkins, was blasting off from Kazakhstan during the seminar, so Marshburn toggled the NASA feed in at an opportune moment to watch the launch. (“I’m getting sweaty palms just watching.”)
With awe in the spirit Tom shares with Davidson, with admiration for him as a fellow Earthling alumnus with “humane instincts and a creative and disciplined mind for a life of leadership and service,” and with thanks on behalf of Davidson to Tom, Ann and Grace for a wonderful visit, I’ll close with a quote from Tom himself, from one of the April satellite downlinks from ISS to the C. Shaw Smith 900 Room:
“I think space flight is actually the epitome of what is important about a liberal arts education. We see this absolute wonder that’s up here, we see it with the robotics of exploration on Mars and in our solar system and even leaving our solar system….
“But how that relates to humans is the most important part of it. We can have complete technical mastery over our world, but we can still do bad things with that. So it’s not just about enriching our culture, which is very important, but it’s actually essential for our survival, that we know what to do with the technical accomplishments we’ve made.”

Since Wildcat NASA Astronaut Tom Marshburn ’82′s conversations from space to the 900 Room, we’ve spotted him flying over Lake Norman several times at dawn or dusk, sun glinting off the International Space Station 230 miles up at 175,000 mph.
Now hear this, just in: NASA will broadcast live coverage of his expedition’s return to Earth May 12-14.
1:30 p.m. EST, 12/21/12: A fittingly joyous (and weightless!) welcome for Tom Marshburn ’82 and his crewmates arriving at the International Space Station. (Click “Expedition 34 Welcomes New Trio.”) What the video doesn’t show is the somersault Tom turned for his daughter! And what a great note on which to wish everyone on Earth all manner of Season’s Greetings up to and including a Happy New Year!
9:50 a.m. EST, 12/20/12: Sitting here at my desk full of doughnuts and bagels and with a steaming cup of coffee, my mind races with questions about how astronauts start their day, or even what a day means up there. More questions than got answered in a first interview with Tom Marshburn ’82 several years ago, and many more to ask during his coming five months at the International Space Station. Send me your questions for Tom at josyme [at] davidson.edu or on the Daybook Davidson Facebook page, and I’ll forward to him once he and his crewmates have a chance to get settled in their unearthly new home.
Meantime, tune in tomorrow, Friday at 8:18 at the NASA TV link above to see their arrival “over the river and through the stratosphere” at the International Space Station!
9:39 a.m. EST, 12/19/12: Docking scheduled for 8:18 a.m. Friday 12/21/12, to be covered live on NASA TV link above
Update 7:25 a.m. EST 12/19/12: Safely in orbit!
I just had a last earthbound e-mail from astronaut Tom Marshburn ’82, who signed off thus:
“Last chance to write you from here on the ground. Launch in 20+ hours. All the best from the frozen steppes of Baikonur, Tom.”
Tune in: December 19, Wednesday, 6 a.m. - ISS Expedition 34/35 Soyuz TMA-07M Launch Coverage (Launch scheduled at 7:12 a.m. ET; includes video B-roll of the crew’s pre-launch activities at 6:15 a.m. ET) – JSC via Baikonur, Kazakhstan (All Channels)
On a clammy, gray Monday morning that does not feel like December in Davidson, Tom Marshburn ’82 (left) broadens the mind’s landscape to the Russian winter and far beyond with this photo of himself and his fellow space travelers, Canadian Chris Hadfield (right) and Russian Roman Romanenko (center).
The three posed for a last snapshot just moments before their departure from Russia to Kazakhstan and quarantine. Their six-month mission to the International Space Station, Expedition 35, is scheduled to launch Dec. 19.
Bon voyage and godspeed, Tom!
I was home sick and watching daytime basic cable (I was really sick), just channel-surfing along and—hey, wait, I know that guy! It was Tom Marshburn, M.D. ’82, Davidson Wildcat astronaut, talking with crewmates about preparations for their upcoming mission. I perked right up, and learned that Marshburn will be a flight engineer on NASA Expeditions 34 and 35 on the International Space Station. He’s currently scheduled to launch on Dec. 19 for a six-month stint (give or take an Earthling day). Here is a starter NASA page to learn more about his pending adventures. He’s on Twitter @AstroMarshburn.
I emailed Tom, who has visited campus and whom we have featured in the Davidson Journal. What a nice guy [drum roll]—very down to earth.
He wrote right back: “Right now I’m back in Russia, having just completed my last training tour in the U.S. with a chance to get everything squared away at my home. It’s chilly here—drops below freezing at night, and no snow yet but it always seems about to come. Ahead are my final ‘exams,’ simulations with my 2 crewmates in the Soyuz spacecraft where we demonstrate our ability to handle emergencies during launch, rendezvous with the Space Station, and re-entry to Earth. In 3 weeks I head for Kazakhstan to enter quarantine in a compound not far from the launch site. We’ll take off from the same pad that Yuri Gagarin launched from 51 years ago.”
Tom graciously offered to put a few davidson.edu email addresses into the NASA “safe” database so he can receive missives from alma mater in the e-packets that NASA will beam up to the Space Station. Got a question? Send it along to me at firstname.lastname@example.org or post it to the Daybook Davidson Facebook page, and I’ll pass it along.
“Like most alums I look back with great fondness on my Davidson years, especially this time of year, and I’d love to maintain the connection,” Tom wrote. And he’s already sent a few Wildcat items ahead to orbit: “I did order a pennant and a new t-shirt, which is actually on-board the Space Station now! I had a chance to send up a few ‘personal preference items,’ and the pennant and t-shirt are included. They launched on an Ariane rocket out of French Guiana early this year, and I was informed that those items were transferred over the hatch to wait for me until I arrive.”
There’s no place like home. Bon voyage and godspeed, Tom!
