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?

Mission Control is a unique environment.  The people who work there are the cream of the crop.  The tops in their graduating classes, the high performers in industry.  And so working in Mission control, my favorite thing is that I get to work with such uniquely talented people, and of all ages.  So it's a place where we can all come together, everybody with their own skill set, and solve the day's problems.

What was your favorite thing about working in Mission Control? (Also, you are the best

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.

When I learned that I had been medically disqualified from consideration of being an astronaut, I was devastated.  My whole life, since I was five years old, I had set my sights on becoming an astronaut, and now I was told that would never happen.  I was- I wanted to quit NASA. I wasn't sure what to do.

But then I took a step back and I realized: maybe I'm twenty-six years old and I don't know everything.  Maybe there are other careers for me here at NASA that I've never considered because I was never aware of them. And I'm very grateful for the fact that I did take the time to think that because you know what? It was true. 

Because I was not able to be an astronaut, I have been able to have what I think is a more fulfilling and impactful career here at NASA.  So for those of you watching, if you have a dream that gets taken away from you, take a step back, reconsider it, and acknowledge that maybe you don't know everything.  And there could be something even greater waiting for you out there.

How did you deal with the disappointment of being medically disqualified for astronaut candidacy?

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?

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?

The CAPCOM is the person in mission control that talks to the crew.  They are responsible for translating all of the discussions and events that occur on the flight loop and mission control into actions and summaries that can be easily understood by the crew.

They are also there to be the advocate for the crew in those discussions in mission control, since the crew can't be there themselves.  So the CAPCOM is really a bridge between what we view as ground mission control and the crew on board.

The flight director is the single authority in mission control.  That person is also responsible for the actions and activities that occur at all of the other mission control centers across the world in support of the International Space Station.  You always have to have one boss and that flight director in Houston is it.

We are responsible for the safety of the crew.  We are responsible for the integrity of the spacecraft.  And we are responsible for the successful execution of the mission.  So any decisions that need to be made in the real-time environment fall under the flight director's authority.

What responsibility and duties does your job include?

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?

"Every job that I have had here, I have had to overcome challenges in order to succeed in it. Whether it's somebody telling me I can't be a flight director because I've never been a flight controller.  Or I can't possibly manage a significant amount of budget and personnel because I've never been a low level line manager before.  

And my--the way I live my life is you never know until you try.  And a lot of people that take on these jobs are never fully prepared when they first start.  But as long as you are fully prepared to acknowledge where you fall short and willing to go off and seek help from people who are masters in those areas, then you will succeed."

What challenges have you overcame to get to the job that you have now? Love from Ireland ❤️

"The answer is both.  You will disappear forever, but you will still exist inside of the black hole.  So how does that work?  

Well, you disappear forever from the point of view of everbody outside of the black hole.  As you get closer and closer to the event horizon you get what we call redshifted.  You get kind of faded away darker and darker and darker until you just disappear.  That's what it looks like from the outside.

From the inside--from your point of view--everything goes pretty well at least for the next five or six milliseconds, before you get crushed to death."

What would happen if I go into a black hole? Do you think I would disappear forever or would I still exist inside the black hole?

"So a black hole is just pure gravity.  In technical terms, that means that Einstein taught us that gravity is energy.  Energy is mass (E = mc2) .

Mass creates more gravity, so you get this essentially runaway effect where gravity is causing energy is causing mass is causing more gravity.

And it just pulls itself in on itself more and more and more, and you get this runaway called a singularity surrounded by an event horizon, which is the black hole."

uhmm, can you tell me what exactly a black hole is? or what iy does? thanks, just really confused and curious on how it actually works.

"We could definitely send a drone to a black hole, collect data, send it back, and study it.  But once it goes inside, once it crosses the event horizon, we're not going to get anything back.  So it would be impossible to know what's inside, but we could learn a lot about what's just outside of the black hole. 

Is it possible?  Sure.  I mean a hundred years ago did anyone think we would be landing rovers on Mars or Titan?  A hundred years from now?  Definitely."

Is it at all possible to send a drone into a black hole and collect the data of what it’s like inside? If not, how close do you we are to possibly achieving that?

"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 the way we understand that black holes form is when a massive star basically runs out of fuel and collapses in on itself.  And the reason that happens is because, the reason stars don't collapse in on themselves on a regular day is because they're hot.  

Hot gas has pressure, so you have all this gas pushing out, you have gravity pulling in and you get a nice balanced equilibrium.  But eventually you run out of fuel, so you run out of temperature, you run out of pressure, and the gravity wins.  So the gravity just pulls in and there's not enough hot gas to hold it up anymore.  

That's how they form.  How do they move?  They move pretty much like every other star in the galaxy.  Mostly orbiting around, for example in the solar system, orbiting around the center of the galaxy with a little bit of random motions here and there."

How do blackholes form and how do they move ?

"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?

"So most of the descriptions that I've seen about black holes in science fiction get it pretty close to reality outside of the event horizon.  Inside the event horizon we don't really know what's going to happen, so a lot of science fiction writers also kind of have fun with it and do whatever they want.  

In terms of outside of the event horizon, I think the most striking effect is that of time dilation, how time slows down as you get closer and closer, but still on our side of the event horizon.  And this was of course one of the major plot drivers of the movie Interstellar, so I thought that was really cool."

Out of all the theories and fantasies created around blackholes, which of them, in your opinion, do you think could come closest to reality?

"Theoretical?  Yeah, I think so, I think we could do it.  Uh, technically there are still a lot of details that need to be worked out."

Could you theoretically time travel through a black hole or other object with such intense mass?

"So, one of the really cool things about black holes that I've been working on recently is using black holes to study another aspect of astrophysics which we don't really understand called dark matter.  Dark matter pervades the entire universe. It's probably five, six times more populous than regular matter, and yet we still have no idea what this stuff is.

The only thing we know about dark matter is that it reacts to gravity.  And if you really want to push gravity to the extreme, of course the way to do it is with a black hole.  So we're trying to understand how dark matter and black holes interact together."

What is the most fascinating thing about black hole research for you, personally?

"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?

"So, the interesting answer is that there probably is a black hole near the earth.  But in space terms, when we say near the earth, we don't mean really that close to the earth.  Maybe about ten or twenty light years away.  Just like the nearest stars are about ten or twenty light years away.  So the difference is that that black hole today is just sitting there, not doing anything. 

The black holes we know about are much farther away, thousands of light years away.  And they're really really bright because they're sucking in gas which gets heated up to millions and billions of degrees and shines in really bright x-rays.  So if one of those really bright black holes were one of the close black holes, about twenty light years away, it would kill us all."

What would happen if a Black hole would be near the earth? What would be the consequences to humans?

"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’m a theoretical physicist, so frankly I haven’t discovered anything in my life, but I have made a handful of predictions.  One of those having to do with black holes is-has to do with the way the light gets bent by the black hole–the extreme gravity of the black hole–so you can get light bouncing back and forth across an accretion disk due to the extreme gravity of the black hole. 

NASA is actually working right now on building a new x-ray telescope that can measure this effect, the extreme light bending by the black hole.  So hopefully in the next few years we will be able to make that discovery and prove that prediction correct.”

What is the most interesting fact that you discovered about Black Holes? And what is the one you would most want to find out?

"So I think what we mean when we say a "gentle" black hole is probably that there's not a lot of hot gas, x-rays, gamma rays, relativistic jets around the black hole.  That makes it safe to go closer to.  In terms of that actually, the supermassive black hole in the center of our Milky Way galaxy, Sagittarius A*, is a pretty gentle black hole.  But even so it still would be far too dangerous to get close to and survive."

Is there such thing as a ‘gentle black hole’ (as in Interstellar) that would one day be a candidate for sending probes? Or is it a lost cause?

"I think the coolest black hole fact is that if the closest black hole to Earth were actively accreting today, it would give us enough x-rays to give every single person on Earth a chest x-ray every ten minutes."

What’s your favorite black hole fact that you like to share with people?

“So, if the sun were just an isolated black hole with nothing around it, we would see nothing.  If we knew exactly where to look–which we would, because we’re pretty good astronomers–and we could map out the solar system, we’d know there’s something in the middle of the solar system that’s causing all of the gravity and the orbits of the planets.  If we looked right at that, we’d actually see some really cool gravitational lensing effects, and you’d see these arcs of light around the invisible black hole called the Einstein ring.”

What do *you* think is inside a black hole? Or If they sun was a black hole what would we see in the sky? Thanks!

“Black holes are just...pure gravity.”

Whats the best metaphor/ explanation of blackholes youve ever heard?
