NASA announced the creation of thisastronaut group in February 2020 and accepted applications for astronaut hires during the month of March 2020. For this class, the educational requirements increased to be at minimum a master's degree in aSTEM field (engineering, biological science, physical science, computer science, or mathematics) from an accredited institution; in classes prior to this, a bachelor's degree was all that was required. Additionally, a 2-hour online assessment was required for the first time.[1] Over 12,000 applications were received by NASA, coming from all 50 states plus theDistrict of Columbia and four U.S. territories.[2]
