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?

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?

On a daily basis?  That's a good question, because when you think of people that might be dressed in flight suits and things or have the duty title of a pilot, that's not all we do.  

Most of our time is actually spent working, coordinating with teams, whether it's scientists with different objectives, learning what they want to do so that we know how to translate that into where we need to put the airplane, to put their instruments in the right place to measure what they want to look at.  Or with engineers, when we're redesigning or modifying aircraft so they can perform the way we want.

That combination there is really pretty amazing.

What do you do on a daily basis?

Oh, for the year to come in 2020, what I'm mostly looking forward to is new opportunities to explore.  That's been one of the most fascinating things in my seven years that I've been a research pilot at NASA is working with different engineering and science teams and learning more and more everyday.

 I feel like - it's just like going to graduate school over and over and learning great new things about the earth's atmosphere and flight research every day.  I just don't have to take written tests or write a thesis or anything like that.  So it's a great way to go to school and learn and explore.

What are you most excited for in 2020?

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?

Yeah, flying's great.  It's a completely different sensation.  You know, you can compare parts of it to things like riding a bicycle, skateboarding, surfing, things like that - even skydiving.  It's a real feeling of freedom when you're actually controlling *makes wing gestures* the aircraft flying through the air - a little bit like a bird. 

And that's an amazing privilege to have, and it's really a nice opportunity to get up there and maneuver in three dimensions - really four dimensions if you consider speed - through the earth's atmosphere.  I absolutely love it.

How does flying feel?

After serving 25 years in the Air Force, as a pilot flying a variety of different airplanes, the more and more I got into different types of missions this just became a fascinating thing looking at everything NASA does with aircraft flying in and out of the earth's atmosphere.  So the opportunity to just make flight research and earth research flying a variety of science platforms was really what attracted me to the job.

What made you want to become a pilot for NASA? What’s your favorite part of this job?

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.

Other than flying in combat in my military days, I would say my time at NASA when I've been exploring--probably the scariest time that I had was taking off in the ER-2 behind me on the island of Oahu off a cliff into the ocean of Kaneohe Bay.  

And the reason for that is it climbs up so steep on initial take-off that at night you just go into pitch black, and all you can see is dark sky and dark water, so you can't tell what's what.  And that gets a little unnerving for about the first minute or two of the flight until you know your way up and away from the water.  Otherwise it's a little disorienting and you could be diving into the water.

Have you ever been scared while flying? What was the event that scared you the most?What's your favorite plane to fly?

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!

Joy is great motivator to do things to do.  And that's actually some advice that I have is whatever you're doing in life, make sure that it brings you some joy.  But there's a lot of reasons that people do things, and I think one of the really great things about being an astronaut is getting a chance to explore.  

We get to do things that are absolutely amazing.  And when we see the planet, we explore outer space, and we get to do all these things and we can come back and we can tell people about it.  So I think it's the thrill of science.  I think it's the lure of discovery.  And then the opportunity to share that with the world is really amazing.

Other than joy, why do you do the things you do?

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?

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?

I thought, um, I actually thought The Martian was pretty good.  They do a good job there of kind of showing the challenges of working in a space environment: some of the isolation, how do you troubleshoot problems, the kind of interactions that crews would have.  I think that's a movie that captures somewhat the feel of space exploration.

What popular film is the closest to reality for you?

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 ??

When you first get into the capsule sitting on top of the rocket, it actually feels incredibly familiar.  It looks like the simulator that we've trained in for years and years, and so you sit down and you strap in, and it feels like you're just gonna go for another three hour sim.  And it might be really boring, and then there might be a fire, and then all of a sudden as you're thinking about those things the rocket starts to lift off and you realize it's not a simulation.  

So there's a lot of g-forces, the rockets shake, and the whole time you're thinking, "this is the most amazing experience I've ever had."  And really, the whole thing culminates at the end of it, after that nine-minute ride when you look out the window and you see the planet.  

We never get to see that in the simulator.

How does it feel to into space for the first time? Like liftoff and leaving earth’s atmosphere? It seems like the world’s terrifying roller coaster, but what’s it really like?

Ah, that's a really good question!  I think I would say, study as much as you did, but also try to have a little bit of fun.

Hey, Kate! What would you say/what advice would you give to your younger self? ✨

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!

Yeah, so the human body changes a lot when you're in space. There's things that happen like fluid shifts, since you don't have gravity drawing the fluid down into your legs, all that fluid shifts upwards.  And the body can adjust to this, it does this by just getting rid of the excess fluid.  When you come back to Earth, however, you're a little bit dehydrated.  So one of the things we do is get fluid in right away.  

Another thing that's concerning is things like bone loss aor muscle loss, so what we do to prevent most of that on board is actually just work out a lot.  We have a device called ARED, which is a Resistive Exercise Device, and we have a whole gym's worth of weight-lifting exercises.  We do that, we do running, and we do cycling.  And that can counteract most of the muscle loss and the bone loss we see on board.  We're really successful in returning astronauts in pretty good health these days.

Is your health affected from being in outer space?

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?

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, 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?

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?

So this was a really neat project.  This was a partnership with hospitals all around the world, and there are kids that are in the cancer units in these hospitals.  And as part of their care they do art therapy.  So they paint, they draw, and they get to express themselves.  

So part of the project was that each kid got a little patch, and they got to paint or draw or color whatever they wanted.  They then sewed all of these patches together to make this space suit, and we got to fly it to the space station.  So it was really neat--all these children got to see their work flown in space.  

But it's so colorful because each individual patch represents a little artist's contribution.  And so I got a chance to meet some of these kids and hang out and do some art with them and it was so incredible.  It was just really a joy to see.

Why's your suit so colorful?

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?

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?

So a lot of the research that we do on board the International Space Station has a relationship to an Earth-based disease.  For example, we worry about bone loss; that's got a relationship to things like osteoporosis on the ground.  All of the things we need to do to keep the human body healthy in a confined environment in the long term we're learning about on the International Space Station.

The things that we do on our six-month missions would build into year-long missions, would build into even longer term missions, for example going to Mars.  So we need to know about things like radiation and the effect on the human body, bone loss, how people are going to be able to work and live together in a confined isolated system for so long.  How we're going to get enough nutrition and getting the right balance of nutrients in a really long duration mission.  And then also, how are we going to keep people healthy?  What kinds of medicines can survive that long in space and how do you treat any illness or injury that occurs?  

So all of these things are actively being researched on board the International Space Station and a lot of them have a component to human health on Earth as well.

How could your research in diseases help missions to the Moon, Mars and other places in our solar system?

One of the things I always find to be most fascinating about spaceflight is that I can be on the phone with a crew member who has called me from the space station while watching them fly over.  And every time I always sit there like a dork and go [waves] "Hiiiii!" as if they can see me.

What aspect of spaceflight always blows your mind, even after all this time?

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?

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
