Robb Kulin was taking a break from his console in SpaceX's Launch Control Center last year when he received a call from NASA to welcome him to the Agency's newest astronaut class.

The choice was given by Kulin, the SpaceX Launch Chief Engineering Group for Flight Reliability, who took the opportunity one day to fly on a Falcon 9 rocket that he had helped design and build.

"If we could really try to show people that borders are something we create, they are not natural. Make the world a better place," said Kulin, then 33, at a press conference in June In 2017, a dozen or so astronauts or ASCANs were presented.

It was the first time in 50 years that an astronaut's candidate filed for CollectSpace.com resigned.

From Anchorage, Alaska, Kulin received a master's degree in materials science and E He holds a doctorate in engineering and had experience as a commercial fisherman in Alaska and as an ice digger in the Antarctic. In 2011, he started working at SpaceX in California, where he worked on the first upgrade of the Falcon 9 Falcon 9 bug.

"My whole goal came out of that and I would say the whole goal of the team was to make sure the Falcon 9 was as reliable and successful as possible, for SpaceX's Comm Ercial partner, but of course also very important for the crew who will fly with this vehicle, "he said last year. "It's something that has helped us get stronger and make me stronger as an engineer."

NASA's last astronomer nominees from Kulin's class are Kaya Barron, Zena Cardman, Raja Chari, Matthew Dominick, Bob Hines, Warren Hoburg, Jonny Kim, Jasmin Moghbeli, Loral O'Hara, Frank Rubio, and Jessica Watkins
