The first uncrewed flight of the spacecraft was launched on 19 November 1999, after which Project 921/1 was renamed Shenzhou, a name reportedly chosen by Jiang Zemin.[citation needed] A series of three additional uncrewed flights were carried out. The first crewed launch took place on 15 October 2003 with the Shenzhou 5 mission. The spacecraft has since become the mainstay of the Chinese crewed space program, being used for both crewed and uncrewed missions.
