Overview of future programs - USA

An overview of U.S. manned space flight is presented and recent advanced studies are considered. In connection with long range mission planning, studies are being conducted of future space systems, space vehicles, and space operations. An early Space Construction Base is being studied for launch in 1985 and associated geosynchronous operations are projected for 1987. The Space Construction Base is envisioned as a facility for erecting large structures in space, for basing Manned Orbital Transfer Vehicles that operate between low earth orbit and geosynchronous orbit; and for the conduct of industrial operations and scientific experiments in space. Ways and means for erecting large structures in space are examined. One particular plan involves the development of the technology to demonstrate the capabilities of a solar power station to translate solar energy to electrical energy for use on commercial power stations on earth. Advanced transportation is also being studied, particularly for needs that complement the Shuttle. The use of the Shuttle System as a Heavy Lift Launch Vehicle to place large diameter payloads up to 200,000 pounds in weight is also being explored.

The Skylab program - An overview

A brief survey is made of significant aspects of the Skylab missions, with emphasis on atmospheric control, electrical power, stabilization and attitude control, prevention of instrument contamination, habitability of the spacecraft, in-flight maintenance and repair, and crew training. Skylab, unlike previous manned spacecraft, had a two-gas atmosphere of oxygen and nitrogen. The station's 25-kW capability was the largest electrical system ever flown in space. Skylab was the first flight application of large control-moment gyroscopes for attitude control. The missions provided significant scientific data in the fields of solar physics, biomedicine, earth resources, and materials processing. Particularly important was the finding of no physical limitation to men's ability to work in space for long periods.

Space Shuttle Program - An overview

The Space Shuttle's unique design features include multiple re-uses of its major elements, large cargo carrying capacity, and the capability of deploying, servicing, and retrieving a variety of payloads. These design features, i.e., reusability and cargo flexibility, were incorporated to satisfy the objective of providing a transportation system which will lower the cost of delivering a variety of payloads to the earth orbit. The Space Shuttle System consists of a reusable manned Orbiter containing three main engines, two reusable Solid Rocket Boosters, and an expendable External Tank containing propellant for the Orbiter main engines. On a typical Space Shuttle mission, the Orbiter will remain in orbit for up to 7 days conducting on-orbit observations and operations, return to earth with personnel and payload, land horizontally on a runway, and be readied for another flight in as few as 14 days. Another mission class includes deploying, servicing, and recovering satellites.
