Explorer 1 liftoff ..... the first true scientific space mission.
Official Announcement.
The Outcome.
August 31, 1956 ?

..... but in 1957, and surely before Sputnik, YES !
Military needs prevailed and the following two launches, in May and August 1957, carried scaled-down development nose cones for the forthcoming Jupiter IRBM.
Then came Sputnik 1 and 2 ..... the Vanguard rocket, in December, burst on the launch pad ..... and America got into a panic .....
..... but the way to Missile 29 was opened .....
