Today astronaut, Robb Kulin, has announced, via NASA spokesperson, that he will be leaving his astronaut training and NASA for "personal reasons." This is a first time occurence for the agency in over 50 years. Kulin was amongst the new class of 12 astronaut recruits announced in 2017 chosen from a total of over 18 thousand applicants. Kulin made his way to NASA and subsequently astronaut training, after working as a senior manager in flight reliability for privatized spaceflight company, SpaceX. The last time an astronaut walked away from training was in 1968.
