“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?
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?
"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?
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?
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?
"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?
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?
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?
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?
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!
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?
