USAF directed all work in Project MX-1593 (Project Atlas) be for development of a rocket-powered ballistic missile.
The uses of rendezvous techniques in space were discussed in a paper read to the Second International Congress on Astronautics in London, England. The problems involved in refueling in space might be simplified considerably if astronauts could maneuver freely, perhaps using a gas-jet pistol and a lifeline. The construction of a space station might then be possible. Mechanical linkage of objects in space was described as the most difficult task of all. While computing the position of an object in orbit might be comparatively easy, linking up with the object without damage by impact would require human intelligence to anticipate error in the attitude of approach.
