While all of this was going on, others were suggesting a completely different approach to the future. They stated that NASA was better off using the existing Saturn to launch their space station, supplied and manned using modified Gemini capsules on top of the Air Force's newer Titan II-M. The cost of development for this looked to be considerably less than the shuttle alone, and would have a large space station in orbit earlier.

With the budgets being pressed by inflation at home and the Vietnam war abroad, Congress and the Administration generally couldn't care less about anything as long-term as space exploration and were therefore looking to make further deep cuts to NASAs budget. But with a single long term project on the books, there wasn't much they could do in terms of cutting whole projects -- the shuttle was all that was left, cut that and there would be no US manned space program by 1980.

Teacher in Space Project
Teacher in Space Project Christa McAuliffe (left) and Barbara Morgan pose in front of the Space Shuttle mission simulator (SMS) after their selection for TISP. The Teacher in Space Project (TISP) is a NASA program designed to educate students and spur excitement in math, science, and space exploration. Christa McAuliffe was selected to be the first teacher in space in 1984 with Barbara Morgan as her alternate. McAuliffe died during the launch of the 25th Space Shuttle mission, STS-51-L, which was to make her the first teacher in space. NASA halted the TISP until 1998 amid concerns surrounding the risk of sending civillians to space. Morgan was selected as the first Educator Astronaut in January, 1998. Morgan is assigned to the crew of STS-118 which may launch

International Space Station
International Space Station Continuing on from the United States' Skylab and Russia's Mir, the International Space Station (ISS) represents a permanent human presence in space. The space station is located in orbit around the Earth at an altitude of approximately 386 km, a type of orbit usually termed low Earth orbit. (The actual height varies over time by several kilometres due to atmospheric drag and reboosts.) It orbits Earth at a period of about 92 minutes; on December 1, 2003 it had completed over 28,700 orbits since launch. It is serviced primarily by the Space Shuttle, and Soyuz and Progress spacecraft units. It is still being built, but is home to some experimentation already. At present, the station has a capacity for a crew of three, who
