American manned spacecraft. Study 1956. April 1958 design of the Navy Bureau of Aeronautics for a Manned Earth Reconnaissance spacecraft - consisting of a cylindrical fuselage and telescoping, inflatable wings for flight in the atmosphere.
In April 1958 the Navy Bureau of Aeronautics presented to ARPA the results of its manned satellite study, "MER I" (for "Manned Earth Reconnaissance"). This approach called for an orbital mission in a novel vehicle - a cylinder with spherical ends. After being fired into orbit by a two-stage booster system, the ends would expand laterally along two structural, telescoping beams to make a delta-wing, inflated glider with a rigid nose section. The configuration met the principal MER I requirement: the vehicle would be controllable from booster burnout to landing on water. Fabric construction obviously implied a new departure in the design of reentry vehicles. At ARPA's direction the Bureau of Aeronautics undertook a second study (MER II), this one to be done jointly on contract by Convair, manufacturer of the Atlas, and the Goodyear Aircraft Corporation. The Convair-Goodyear study group did not make its report until December. At that time it reasserted the feasibility of the lifting pneumatic vehicle but relegated the inflation of the craft to the post-entry portion of the mission. By December, however, Project Mercury already was moving ahead steadily under NASA. Funds for a MER III phase (model studies) were not forthcoming from the Defense Department, and the intriguing MER concept became a little-known aspect of the prehistory of manned orbital flight. Project MER was by far the most ambitious of the manned space flight proposals made by the military in 1958. Its emphasis on new hardware and new techniques meant it really had little chance for approval then.
AKA: Manned Earth Reconnaissance.

Man-In-Space-Soonest The beginning of the Air Force's Man-In-Space-Soonest program has been traced back to a staff meeting of General Thomas S Power, Commander of the Air Research and Development Command (ARDC) in Baltimore on 15 February 1956. Power wanted studies to begin on manned space vehicles that would follow the X-15 rocketplane. These were to include winged and ballistic approaches - the ballistic rocket was seen as being a militarily useful intercontinental troop and cargo vehicle. More...
Associated Launch Vehicles
Atlas The Atlas rocket, originally developed as America's first ICBM, was the basis for most early American space exploration and was that country's most successful medium-lift commercial launch vehicle. It launched America's first astronaut into orbit; the first generations of spy satellites; the first lunar orbiters and landers; the first probes to Venus, Mars, Mercury, Jupiter, and Saturn; and was America's most successful commercial launcher of communications satellites. Its innovative stage-and-a-half and 'balloon tank' design provided the best dry-mass fraction of any launch vehicle ever built. It was retired in 2004 after 576 launches in a 47-year career. More...

- Project Mer - .
Nation: USA. Spacecraft: Project Mer. The Navy space proposal to the Advanced Research Projects Agency, during the tenure of that organization's interim surveillance over national space projects, was known as Project Mer. This plan involved sending a man into orbit in a collapsible pneumatic glider. The glider and its occupant would be launched in the nose of a giant launch vehicle. After the glider had been placed in orbit, it would be inflated, and then flown down to a water landing.
