It was also offered to NASA to carry an 8-man crew to Mars and back in a matter of months. Although subscale tests were performed using conventional explosives, and full-size nuclear pulse units were allegedly testing, the political implications of developing such a drive and the Nuclear Test Ban treaty resulted in it's cancellation around 1965.
