Group 9 looking fine! #OTD in 1980, NASA announced 19 astronaut candidates for its 9th astronaut class. (16 of whom are pictured here.) Group 9 included 8 pilots, 11 mission specialists, plus 2 international mission specialists. All together they flew 65 Shuttle flights!

NASA History Office SpaceX NASA Five years already! Also the first crewed test flight of an orbital spacecraft since 1981. Truly an incredible achievement by the dedicated teams from NASA and SpaceX in Hawthorne, MacGregor, JSC, and KSC. Congratulations and thank you. Amazing to see where we are now!
