Tragedy Remembered: January 28, 1986

On that fateful winter day in 1986, I was a newly minted grad student at UCLA in the then-fledgling area of cognitive science, where I was able to assemble my own interdisciplinary course of study and research. I chose computational psycholinguistics, which meant that my goal was to invent the Universal Translator (as seen on Star Trek) by the time I was 25 and single-handedly revolutionize global and cross-cultural communication.  The reality of technological limits put a damper on these aspirations soon enough. But in the winter of 1986, I felt I was in the right place at the right time to change the world.
In addition, just a couple of weeks prior, I had met a human factors engineer who was working on improving the space shuttle crew compartment and on designing living quarters for the planned space station, which was named “Freedom” at the time, a very ambitious project that was later scaled back into what is now the ISS. She soon hired me as a consultant, once she realized that I have a background (more by accident than by choice) in quantification of human movement across three dimensions. We spent many hours together in front of a TV set and VHS VCR, watching NASA footage of astronauts moving about various shuttle compartments in space, followed by many more hours of devising ways to measure and quantify their movements. Most of the footage was from Challenger missions.
It was during these hours that I lived through one of the most intellectually embarrassing moments of my life. While we were discussing the difficulties that moving about in microgravity added to obtaining consistent measurements, I suddenly had a seemingly brilliant idea: “Hey! Why don’t we suggest to NASA to film astronauts in microgravity during an upcoming mission – have them do some basic movements that can be used as baselines. Put some lead boots on them so they’ll always have their feet on the floor!”  I looked at her expectantly and could tell she was trying not to laugh. :::::dramatic pause::::: …. and…. the light went on in my brain (about 30 seconds too late, thanks a lot, brain). I just wanted to disappear. Thankfully, she laughed and said “Don’t worry – that happens to everybody!”
This collaboration ended with a job offer to work full time in human factors psychology to design living quarters on space station Freedom.
So the question “Grad school as I had planned or a job in the space industry that just happened to fall into my lap?” was very much on my mind as I walked across the UCLA campus to the research methods lab class I was teaching early that morning on January 28, 1986. I knew there was a launch that morning, but like so many others, I had already started taking them for granted after 5 years and didn’t give it much thought. I walked through the student union where everybody appeared to be clustered around two TV sets. Deep in my own thoughts, I ignored them and figured it had something to do with a football game, the only other occasion during which I had seen students glued to the TVs like that.
When I walked into my classroom I could tell instantly something was wrong. I attempted to make a joke about “all the long faces”. “You don’t know?” one of the students asked. “Know what?” “The space shuttle! It exploded! They’re all dead!” (I realize Challenger did not actually explode and there had not been any official announcement on the fate of the crew). The news hit me like a physical punch. I took two steps back against the wall and had to consciously keep from sliding to the floor. I don’t remember much after that. I don’t remember if I taught the class, cancelled it, or anything else about that day. I do remember very vividly that the wait for answers about what had happened was frustrating and excruciating. I never looked at a space shuttle the same way again. And I never once took them or their voyages for granted again.
I did stay in grad school. The job offer was still on the table, but I decided against it. A year later, the human factors program for space station Freedom was cancelled and my friend was transferred to a department that had her working on improving the ergonomics of combat plane cockpits. After all, this was the era of Star Wars. No, not George Lucas' Star Wars. Rather, the giant defense industry boon(doggle) that was Ronald Reagan's Star Wars.
I don’t usually believe in chasing “What ifs” but in this case it’s hard not to speculate.
I keep Challenger’s last mission patch in a special place – as a reminder not of what could have been, but as inspiration for all that which we will yet achieve in space.

Soyuz Expedition 33 Returns to Earth

On Monday morning, November 19, 2012, Soyuz Expedition 33 landed near Arkalyk, Kazakhstan. The capsule carried three astronauts returning from a 127-day stay on the International Space Station: Akihiko Hoshide (@aki_hoshide) of the Japan Aerospace Exploration Agency, Russian Soyuz Commander Yuri Malenchenko and NASA astronaut Sunita Williams (@astro_suni), who became the second woman to command the ISS. 

Expedition 33 made a rare night landing on the Kazakh steppe at 7:56 a.m. local time, before local sunrise. The temperature was well below freezing and the capsule landed on its side in the snow - but not before leaving a spectacular scorch and drag mark. As much as I love the space shuttle, you just don't see that sort of thing on the Cape ~

All three astronauts were recovered from the Expedition 33 capsule in good spirits. 

Oh, and am I the only one who thinks that the Soyuz capsules should be *named*?
