Human Space Flight Is Very Stressful, And Particularly As A Flight Director With The Responsibility For

Working at NASA has been an extraordinary experience and I have a lot of memories I can tell you are my favorite.  But there's one in particular that stands out above the rest.  

I was a new flight director, only been in the office for two years, and we were executing the STS-120 mission, where we were taking these solar arrays that are in blankets, and you put them up on board the space station and you unfold them like an accordion.  

As we were unfolding one of them, we saw it rip.  And by the time that the power discipline expert could make the array stop, we had a huge tear inside the solar array.  After several meetings, it became clear that we were not going to be able to undock the shuttle in that configuration and we had to figure out a way to fix the solar array.

At that time I was working at what we called a team four.  So three teams used to support the shuttle mission, but we always had a fourth team waiting in the background for something to go wrong.  So at that point we called together a meeting and a young engineer showed up who was about 24/25 years old.  And [he] said "Flight!  I have a solution!"

So he walks into my meeting with this. [holds up object] And I said, "what is that?"  

And he says, "It's a cufflink, Flight, and I made it out of spare parts that are available to the astronauts on the space station. And if you take this and you weave it through some of the holes and you pull it tight, we'll be able to secure the solar array."

And so sure enough, we were able to take this cufflink and a couple more like it, and put one of our tallest crew members on board a stacked set of robotic arms and he installed a cufflink.  And that cufflink is there today and keeps the space station solar array structurally sound.  So best moment ever.  You never know what a 24/25 year old can accomplish.

What has been the best memory you have so far at NASA?

My mother gave me the best advice I'd ever received, and it was "trust your instincts."  I've applied that when I was afraid to go away to college, and she told me, "Trust your instincts, stay at home."  

I've applied that every time I take on a new position where I'm afraid: I think I can do it, I'm not sure if I know everything that's required, but I'm pretty sure I could do it.  So trust your instincts, even though you don't have all the information, believe in yourself and you can achieve great things.

What’s the best piece of advice you have ever received?

Yeah, we had to troubleshoot problems pretty much every day.  So, we have our tasks that we’re doing every day: a science experiment or some maintenance, but things don’t always go as planned.  So that’s one of the really interesting things about science experiments is that sometimes you observe things that are different and that’s how science gets done.

One of the experiments I worked on was actually doing a chemical reaction with some small little pockets of–they’re plastic kind of tubes that contain pockets of water.  And we heated the reaction and we noticed that there were bubbles being formed.  When we did this reaction on Earth we didn’t have the same thing, so we had no idea was to expect when we did this on board.  So we documented this and actually found it to be a really interesting phenomenon.  The scientists took that back and that ended up being part of our analysis of the experiment.  

Sometimes you’re just troubleshooting equipment because things aren’t working.  So I was working on one of the vacuum furnaces one day, and it has these quick disconnects that you can use to supply power or water to the vacuum furnace.  And I tried to do one of the quick disconnects and all of a sudden the connection–the valve–stayed full open and there was water spreading everywhere.  

So that was some really quick troubleshooting, I had water going in my face and I wasn’t really sure what to do so I closed the thing as quickly as possible, backed off, got the water out of my eyes, and then I called the ground and we did a lot of troubleshooting that day.

Have you ever had to troubleshoot a problem in space?

I would say my favorite part of the job is not really what you'd think.  You'd think it's maybe strapping in an airplane and going up and flying - and that's a wonderful opportunity, and I love it absolutely - but really the greatest thing at NASA, and I think most people would agree, is working with the people that we have here.  

Because the people that come together with an eagerness to explore and to experiment with things and discover new opportunities and things like that - working side by side with those people is what really gets your heart pumping and makes you excited to come to work each day.  So that's what I'd say is my favorite part of the job.

What’s your favorite part of the job?

The first time I saw Earth from space I couldn't even talk; I was absolutely speechless, as were my crewmates.  The three of us were just silent it seemed like for thirty seconds, it was such a beautiful sight.  And one of the things that was really interesting to me was how different it was seeing it out the window with your own eyes versus seeing the picture.  

I think I had this idea in my head that I knew what Earth looked like because you've seen so many videos, but they're all photographic images, so the dynamic color spectrum is a little bit dulled.  When you see it with your own eyes, it's so much brighter.  It's so much more vivid than I could have imagined.  It's just this beautiful blue planet.

What was your first thought when you first saw earth from space? And what realizations did you have?

Yeah!  So if you want to be an astronaut, my best piece of advice is definitely to study something in the science field.  Basically every astronaut has some kind of background in science, technology, engineering.  Everybody has--even the fighter pilots have studied something and done a Masters degree in some kind of STEM field.  So if you start there, you're definitely headed in the right direction.

What is your advice to someone who wants to follow the same steps you take?

We train a lot for space walks, so hundreds of hours underwater in the pool, and we spend a lot of time going over every detail of the space walk.  But one of the things you really can't train for is the feeling you're in an absolute vacuum.  So we do a few tests in the vacuum chamber, but when you first go outside the hatch and you see the total darkness or the brightness of the Earth, and you realize that there's no air molecules anywhere else around you - that's the biggest surprise.  

And then I think the second surprise is after an hour or two, getting comfortable working in an absolute vacuum, knowing that the suits are going to protect and you have a whole team of people on the ground taking care of every aspect of that spacewalk.  I think that was the thing that was the most surprising, was how alone and distant from the planet you can feel, yet totally supported by all the people working down in Mission Control.

I’m sure you’re trained so that nothing in space is really a surprise, but: was there anything about spacewalking that surprised you when you did it for the first time?

"So I got started working on black holes my first year in graduate school.  I actually tried another research project first about cosmology, but frankly the math was just too difficult for me, so I decided to go into easier things: black holes."

I love astrophysics and especially black holes and I want to pursue a career on them, but to be honest I'm scared to be not good enough or not clever enough. How did you decide to work on black holes? How did you become the person you are today?

So one of the things I didn't know about being an astronaut was all of the different kinds of skills we need to learn.  You come in and you're kind of a baby astronaut trainee, and they teach you things about like how to fix the electrical system and the plumbing on the space station.  You need to learn how to train in dangerous environments.  We learn how to fly airplanes.  We learn how to do spacewalks underwater.  

So one of the most surprising things was just the variety of skills we need in order to be successful expedition pioneers on board the space station.

What's something you didn't know about being an astronaut before you actually became one? Do you have any words of advice for young astronauts?

So when I was inside the space station, one of my favorite things to do was go in the Cupola, which is an area that has a whole bunch of windows.  You can actually get your whole body into the Cupola and just see the Milky Way and the universe from the Cupola.  And that was amazing.  

It was, um–you know terrifying is almost a good word because it was so awe-inspiring to just be in the universe and see the stars–but it was one of the most interesting things to do because it was always changing.  Your view was changing as you go around the planet; even at nighttime you can see different aspects of the planet at night as well. 

And so whenever I could, I would spend a few minutes when we were in a dark orbit and just try to poke my head into the Cupola and see the stars. It never got old.

What is like to be surrounded by the stars and darkness? Is it terrifying or calming?
