"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?
"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?
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?
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?
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?
Yeah, that's a great question and that's exactly how it feels. Once we get up about 13 miles above the earth, and get everything set up and start doing the science collection, every now and again you have to kind of stop and just take a minute to look around. And it's a fascinating sight up there.
On a normal clear day looking down at the earth, you can see the curvature of the earth out in front of you, and then the sky is just a really dark purple up there because you're above all the moisture in the air that causes the dark blue to turn to light blue down towards the earth's surface. And it's such a different sight, it really makes you understand how small we really are.
What does it feel like to be up there and look down at the Earth? I've always imagined it would send me into a moment where I feel so small compared to the expanse and beauty of Earth.
"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 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?
I think it's actually just an incredible thing that we have picked a line-up of space-walkers--we've taken the most qualified people--and we happen to have enough female astronauts that we have two women doing a spacewalk now. I think it really is a testament to NASA's inclusivity in their selection process.
The last several classes we've seen a lot more women applying in these classes and also being selected. And so I think everybody can look at that and say, "You know, that could be me someday!"
As an astronaut who has been on a spacewalk before, what does the all-woman spacewalk mean to you?
Yes, there’s several paths to get to where I am right now and where the other researcher pilots are here at NASA. We have some that come up through civilian flying and they’re educated in different areas. Typically most of us have engineering or STEM related degrees in college, and usually Masters degrees on top of that.
The flying portion, most of us actually come from a military background because that’s the best way to get a lot of intense experience very quickly. So most of us are retired military pilots from all different services, but then we do have several pilots who have grown up flying corporate jets, larger airplanes and became test pilots for companies like, say, Boeing and Lockheed Martin, things like that. And then they get hired at NASA based on their depth and breadth of experience.
So several paths to get there, but these are the most common.
I want to pursue a career in aeronautics and want to get into NASA. Any advice?
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.
