In My 28 Years Here, I've Been Able To Participate In A Lot Of Exciting Missions, But Out Of All Of The

"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?

I remember my first day on console as the first non-astronaut CapCom, and the very first time the crew called down. I was getting ready to key my mike and speak back up and they asked me a question, and I looked at the Flight Director beside me, he gave me a go, and I answered.  And there was a pause.  

And it was Frank Culbertson, and he called down and he was like, "Ginger!  Is it really you? Oh my gosh, it's so awesome to hear your voice!"  

So that kind of eased my tension.  The reality was the first set of crews that I wound up working with I had trained alongside for four years.  SO it was a treat to be able to be in a position where I could talk to my friends.  But I understood what they'd gone through, I understood Mission Control, and I could be their advocate in Mission Control.  And I could tell from day one that they trusted me and they were happy that I was there.

How did the crews react to you being the first non-astronaut CapCom? I understand it was quite an important thing to people that the CapCom could empathise with their experiences.

Yeah, that's a wonderful thing.  And whether you're flying low level, over the earth's surface, or way up high in the earth's atmosphere like with the ER-2, there's different sights.  

One thing I like about flying low level is the vegetation, the hills, the mountains, the water - where you see details in the waves and the trees up close that are just absolutely beautiful.  Conversely, when you're way up high  you see everything.  And that's where you realize how many different pieces of the earth's surface come together, between the oceans, the big lakes, the mountains and everything, and the colors are so different that all they just paint an incredible picture from 13 miles above the earth.  

And when you look from the surface up through the beautiful atmosphere that we have from where the sky moves from a light blue color and then gradually gets dark blue and then purple and even starts to turn black way up high, that's just an incredible sight that I feel real privileged to see every time I go up there.  It's a privilege, it's just amazing.

What's the most beautiful natural scene uou've ever seen personally, as in Aurora Borealis, volcanic eruption, or something that made you seem like the Earth should be treasured?

Human space flight is very stressful, and particularly as a flight director with the responsibility for the safety of the crew and the integrity of the vehicle and the execution of the mission, I was very stressed during those years.

One of the things I love to do to de-stress is to run.  So during the Expedition 14 mission, which was seven months long, I was very stressed.  And I figured, hey, why not train for a marathon?  So after training for several months, I actually ran a marathon.  

And this is a picture of me [shows laptop screen] talking to the commander of the International Space Station, Mike E.L.A.  He called my friend while I was at mile 23.  Mile 23!  I'm supposed to be focused!  But she hands me the phone and he says, "Hey, I've had people posting at all the different mile markers and you are looking great out there, so..."

And I said, "Well, can I-can you call me back in like--mmm--thirty minutes because I might be across the finish line by then, and right now I'm kind of busy." ________________

Transciber note: She pronounces name of the commander of the ISS as “Mike Elay”, but a quick google shows that Michael E. Lopez-Alegria was the commander of Expedition 14.  In case you were wondering about the three initials.

What do you do to relax in stressing situations?

So on the ISS we have a wake-up time.  There's not really any predetermined time because we're orbiting the Earth every ninety minutes.  But you have to pick a time scale, so we actually picked GMT, which is close to London time.

So we wake up, we have a normal conference call with the ground, we talk about things that are going on the space station, what we're going to do that day, and then we have a plan that tells us what we're going to do down to every five minutes on board.  And so it depends on the day.  

A lot of time we're doing science experiments, sometimes we're doing maintenance on the space station, sometimes we're even getting ready to do a space walk.  Those are the best days.  But every day is something new and different up there.

What does a normal day for you consist of?

"Time works like a lot of things in Einstein's Theory of Relativity: it's relative.  The way that time works according to, say, a person in a spaceship flying into a black would look pretty normal. An astronaut could look at his watch and it would be going more or less normally.  

But the time connected to the outside world, outside of the black hole, would just break down entirely.  It's essentially forming a wall between inside of the black hole and outside of the black hole. And the time on the two sides of that event horizon are just going to be completely different."

How does time work in a black hole?

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?

Being a flight director was such an honor.  I was only able to do it for eight years, but I loved every minute of it.  My favorite part about that is being able to lead such talented teams.  

I had a different team with me every day, different teams on different missions I supported, but the one consistent thing is that they are all dedicated to flying these vehicles safely, to protecting the crew, to executing the mission.  

And it was just an honor to be able to lead them. I considered it a successful day if I didn't have to step in and I could just sit back and watch the team do their thing, and they are beautiful.

What was your favorite part of being a Flight Director?

"Short answer: No.  Long answer: Definitely no."

Science fiction sometimes makes it seem like it’s possible to live in a black hole. What is the truth behind this?

"So, I think we're studying them simply because they're fascinating.  This is how a lot of pure science is motivated.  What are the questions about the world around us that fascinate us, and for me at least black holes is at the top of that list.  If we're looking for more technical applications, like is it going to make the next new cell phone work better?  Probably not.  

But a hundred years from now we really never know where some of these pure science ideas are going to go.  For example, if you think about electricity and magnetism and quantum mechanics a hundred years ago, similairly in the pure pure science realm and now they dominate every aspect of our lives."

Why are we studying them? What’s purpose of this field for us on earth?
