"So, I Think We're Studying Them Simply Because They're Fascinating.  This Is How A Lot Of Pure Science

So floating is really interesting.  You're actually very unstable when you float for the first time because your body's rotating on all these different axes, and anything you touch anything, you're inputting motion into that system.  So one of the things we learn the first week or so we get on board is how to stabilize ourselves.  

So we actually hook our feet underneath some hand rails and kind of use our toes [wiggles fingers] to keep ourselves steady.  Then--only then--when we've mastered that, we start to learn how to float in a given direction.  We learn how to push off and get to where we want to go.  It's not always perfect at first, there's a lot of times when you bump your forehead into the hatches or you slam into the wall and knock the computer off.  That's like every first time astronaut experience. But after a little while, you get pretty good at getting around the space station.  

It's a whole 'nother concept when you come back to Earth and you have to remember how to walk again.  So again, there you're kind of unsteady the first few days you're figuring out--your feet haven't touched the ground in a long time, so you have to figure out how to walk. And then you move on to how to jump, and then finally you get good enough and you can learn how to run again.

What does it feel like to float?? Do you have trouble adjusting to walking on the earth after that ??

Hi, I'm Dean Neeley.  I go by "Gucci".  I"m the deputy chief pilot at Armstrong Flight Research Center.  And I'm excited to be here and answer some questions to everybody who's calling in through tumblr here.  This is a great opportunity to share with you.

It’s kick-off time! Pilot Dean “Gucci” Neeley is reporting for duty with answers to your questions in today’s Tumblr Answer Time!

I think some of the greatest things that we can take a look at what we're currently doing in space and see that future generations are really going to appreciate is all of the science that we're doing on board the International Space Station. So I was lucky enough to participate in just a few of those science experiments.  We did about a hundred different science experiments that I actively participated in on board, two hundred total.  

And I think that's just adding to the knowledge about how the human body works in microgravity, and also how we're going to explore, both in lower orbit and then beyond deep space exploration.  So all of these little bits of scientific inquiry add up to really a big body of knowledge, and I hope that's the legacy of the International Space Station and NASA's work in space.

Hii! I'm unsure if you've been asked this before, but I'd like to give it a shot anyway. What's the greatest legacy you hope to leave to the future generations? Whether it's one of the things you've accomplished already or are hoping to accomplish yet. Thank you very much!

“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?

In my 28 years here, I've been able to participate in a lot of exciting missions, but out of all of the future missions we have planned the one I'm looking forward to the most is being a part of boots on the moon in 2024.

What future missions are you looking forward to the most?

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

"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.

Over my 28 years here, I've had the opportunity to work a number of different critical missions at NASA, particularly as a flight director.  And each one of those missions has been an amazing honor to have the public's trust put in my hands.  

But one of the aspects I like the most about it, which is also the scariest, is the fact that people's lives are in my hands.  Decisions that I make can impact the lives of the crew members, the integrity of the vehicle, and the success of the mission, and I liked having that responsibility.  I was honored to have that responsibility.

And I think if you are a flight director and you ever lose track of that, then it's time to stop being a flight director.

Before my question I would like to congratulate you on your career at Nasa, it must be amazing to work there even if you didn’t achieve your dream of being an astronaut, you can still lead missions from the ground. (Sorry if my punctuation is a bit off) as for my question, what has it been like to work at nasa all of these years and get to help with so many missions? Do you ever get nervous for the people who’s lives are in your hands? Signed ~ Phillip

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

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

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?
