An astronaut-in-training quits NASA for 1st time in 50 years
Astronaut candidate Robb Kulin has resigned halfway through his two years of training at NASA over personal reasons, marking a first since 1968 when another astronaut-in-training quit. The former SpaceX manager was among 12 astronauts chosen last summer from a record 18,300 applicants. Notably, Indian-origin US Air Force Lieutenant Colonel Raja Chari is also part of the 2017 Astronaut Class.
