The Space Agency announced the 2017 astronaut class in June 2017 . They reported on their two-year training this August.
According to NASA, Kulin, 35, is a native of Alaska. He holds a bachelor's degree in engineering from the University of Denver, a master's degree in materials science, and a doctorate in engineering from the University of California, San Diego. Prior to being selected as an Astronaut candidate, he was Senior SpaceX Flight Safety Manager and led the Launch Chief Engineering group at Hawthorne, California, where he has served since 2011.
The resignation, valid from August 31, 2018, would leave only 11 members in the 2017 NASA class. It's the first time since 1968 that an astronaut resigned in training. This year, two members of the 11-member group selected by the Space Agency in 1967 left the Space Agency: Anthony Llewellyn in September for personal reasons and [Brian O] Leary in April for "Lack on space exploration prospects, "NASA said.
According to the Houston Chronicle, NASA spokesman for the Johnson Space Center, Brandi Dean, said the space agency did not intend to replace Kulin. This leaves 11 members in the NASA Astronaut Group 22, nicknamed "The Turtles". The other members are Kayla Barron, Zena Cardman, Raja Chari, Bob Hines, Warren Hoburg, Jasmin Moghbeli, Jonny Kim, Loral O & # 39 ;. Hara, Matthew Dominick, Frank Rubio and Jessica Watkins.
Derek Richardson holds a degree in mass media, with a focus in contemporary journalism, from Washburn University in Topeka, Kansas. While at Washburn he was editor-in-chief of the student newspaper Washburn Review. He also has a blog about the International Space Station called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the satellite MUOS-4. Richardson joined our team shortly thereafter.
His passion for space caught fire as he watched Space Shuttle Discovery launch into space on October 29, 1998. Today, this excitement has accelerated towards orbit and shows no sign of slowing down. After trying his hand at math and engineering classes at college, he soon realized that his true vocation was to communicate with others through space. Since joining SpaceFlight Insider in 2015, Richardson has been working to improve the quality of our content and ultimately become our editor-in-chief. @TheSpaceWriter
