Meanwhile the Air Force had a continuing interest in smaller systems with more rapid turn-around times, and were involved in their own spaceplane project called Dynasoar. In several instances groups from both worked together to investigate the state of the art.

Shuttle development

The shuttle program was launched on January 5, 1972, when President Richard M. Nixon announced that NASA would proceed with the development of a reusable low cost space shuttle system.

The project was already to take longer than originally anticipated due to the year-to-year funding caps. Nevertheless work started quickly and several test articles were available within a few years.

Most notable among these was the first complete Orbiter, originally to be known as Constitution. However a massive write-in campaign on the part of fans of the TV show Star Trek convinced the White House to change the name to Enterprise. Enterprise was rolled out on September 17, 1976 and later conducted a very successful series of landing tests which was the first real validation of the gliding abilities of the design.

The first fully functional shuttle orbiter was the Columbia, which was delivered to Kennedy Space Center on March 25, 1979 and was first launched on April 12, 1981 with a crew of two. Challenger was delivered to KSC in July 1982, Discovery was delivered in November 1983, and Atlantis was delivered in April 1985. Challenger was destroyed in an explosion during launch in January 1986 with the loss of all seven astronauts on board, and Endeavour was built as a replacement (using spare parts originally built for the other orbiters) and delivered in May 1991. Columbia was lost, with all seven crew, in a re-entry mishap on February 1, 2003.

The Air Force relucantly agreed, but only after demanding a large increase in capability to allow for launching their projected spy satellites (mirrors are heavy). These were quite large, weighing an estimated 40,000 lbs, and needed to be put into polar orbit, which requires more energy to get to than the more common LEO. And since the AF also wanted to be able to abort after a single orbit (as did NASA), and land at the launch site (unlike NASA), the spacecraft would also require the ability to manuver significantly to either side of its orbital track to adjust for the launching point rotating away from it while in polar orbit - in a 90 minute orbit Vandenberg would move over 1,000 miles, whereas in a "normal" equatorial orbit NASA needed the range would be less than 400. This large 'cross-range' capability meant the craft had to have a greater lift to drag ratio than originally planned. This required the addition of bigger, heavier wings.

Teacher in Space Project

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

Space Shuttle Columbia
Space Shuttle Columbia Shuttle Orbiter Columbia (NASA Designation: OV-102) was the first space shuttle in NASA's orbital fleet, first flying mission STS-1 from April 12 to April 14, 1981. It was lost with all crew when it disintegrated during re-entry on its 28th mission, STS-107, which lasted from January 16 to February 1, 2003.

Space Shuttle program
Space Shuttle program Space Shuttle Columbia, 1981 (NASA) NASA's Space Shuttle program is an ongoing endeavor, started in the late 1960s, that has created the world's first partially reusable space launch system, and the first spacecraft capable of carrying large satellites both to and from low Earth orbit. Each shuttle is designed for a projected lifespan of 100 launches. The original purpose of the program was to ferry supplies to a space station. In reality, the Shuttle is the United States' sole manned launch vehicle and has totally dominated NASA's operations since the mid 1970s. With the construction of the International Space Station the Shuttle has finally begun to be used for its original purpose. In January 2004, it was announced that the Shuttle fleet would

Space Shuttle Columbia disaster
Space Shuttle Columbia disaster Crew of STS-107 on launch day () STS-107 was a space shuttle mission by NASA using the Space Shuttle Columbia. The entire seven member crew was killed on February 1, 2003, when the shuttle disintegrated over Texas during reentry into the Earth's atmosphere.This was the second total loss of a Space Shuttle, the first being Challenger.

Statistics

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.
