Just as class lets out for the summer across the country, a new one has just been announced.
NASA has chosen 12 people from a pool of more than 18,300 applicants for two years of training before giving them the title of "astronaut."
The space agency received a record number of applicants after announcing an open application in December 2015.
Jasmin Moghbeli, one of the dozen candidates, spoke with NPR's Lulu Garcia-Navarro from Houston's Johnson Space Center, where she'll undertake the training program starting in August.
Moghbeli, who says she's wanted to be an astronaut since the sixth grade, talked about what kind of candidate it takes to earn the coveted spot.
"Start looking into science, technology, engineering, math, those kinds of fields," the German-born, New York native says. But whatever you do, she says, love it.
"There were many other applicants that applied who were extremely qualified for this position that aren't lucky enough to be sitting up here like I am," she adds. "So make sure you're doing what you love. If I did not get the call saying, 'Hey can you join us here at NASA?' I still would've been extremely happy in the career that I was in."
The seven men and five women of the class bring an impressive resume to NASA: The astronaut candidates are an athletic crew and include former SpaceX employees, a marine biologist and half of them are military officers.
"You are the 12 who made it through, you have joined the elites, you are the best of us," Vice President Mike Pence said at a ceremony introducing the candidates Wednesday. "These are 12 men and women whose personal excellence and whose personal courage will carry our nation to even greater heights of discovery."
Current and alum NASA astronauts welcomed the newest class in a video last week.
You can find the full biographies of each new class member on NASA's site, or meet the candidates below the interview highlights.
NPR radio producer Malika Gumpangkum and editor Ed McNulty contributed to this report.
On the application and job interview process
It starts out a little underwhelming — you just submit your resume on USAjobs[.gov] and, in addition to that, just my summary of my aeronautical experience — so basically my piloting time. So that's the first step, as I said, very simple. But then from there, they select highly qualified applicants and send reference forms out to you, five of your references — and then that's where it got interesting.
They slimmed it down to 120 applicants and they brought us in in groups of 10. The first round was three days of interviews — you know, only three days I could say I got so close to that group of nine other people and we still keep in touch. And then, the final round, they pair it down to 50 people, and again, 10 at a time, but this time it's a week-long process. So you can imagine, you get really close with the other applicants, and I left that thinking: Wow, I want this job even more, based on the incredible people I've met, both at NASA and the applicants, but also thinking: if I don't get it, someone very deserving will get it, 'cause every single one of them had a very impressive resume.
On the toughest question she was asked
First they asked, three words friends would use to describe me, which, I didn't have a problem with that, but then they asked one word I would use to describe myself, and I don't know, it's just tough to pick one word. And out of nowhere I said, "intense," and I think I was just feeling intense in that moment in the interview, but I don't know that that's really the single word I would use to describe myself.
On wanting to be an astronaut from a young age
I did a book report on Valentina Tereshkova, the first female in space, got to dress up like her in school for a day. I'd always been interested in science, math, technology, that sort of thing always drew me in. And, added to that, the sense of adventure and exploration, you know, I thought space exploration was the coolest thing. So yeah, I've wanted to do this for a very long time.
On why so many people want to be an astronaut today
I think it's one of those things that ignites our imagination. I remember when I was a kid in history class, reading about the explorers who would travel across the ocean and discover new continents and, you know, different worlds to them at the time. And this is kind of our modern-day version of that. We're going off and exploring where we've never been before. One, the teamwork at NASA, I think people are pretty familiar with NASA's record and the incredible things that have been accomplished here. And it's just really impressive to see — when you bring a group of smart, hardworking people together — what you can accomplish. So, I think all those things get people excited and that's why it's almost like, even as an adult, gets you excited like a little kid.
On what she's being trained on
There are a lot of things on the horizon right now, I know learning about the systems on the [International] Space Station will be part of our training over the next two years. But they're training us, and like I said, there's a possibility of a range of missions that we could go into.
Right now, both Boeing and SpaceX are working on commercial crew vehicles — the CST-100 Starliner and the Dragon vehicle. ... And then NASA itself is working on the Orion. So, a lot of new, exciting things coming up that we could potentially be doing in the near future. ... If they could assign me any mission, I'd be overjoyed.
On her message to young girls, particularly of color
That is one of the most exciting things about this job for me. Not just exploring space and that stuff but also getting the message out to the younger generation and getting them excited. If they can see someone similar to them that they can relate to more, then it makes it all that much more possible in their minds to imagine them doing this as well. So, to them I say, do what you love and do it well.
