Towards the end of the Apollo program, NASA officials were already thinking about what 00:00:00
would be next for the American space program. 00:00:10
At that time, the rockets used to place astronauts and equipment into space were designed to 00:00:13
be used only once. 00:00:17
Although effective, NASA planners decided that they needed a system that was less expensive, 00:00:19
reliable, and perhaps most of all, reusable. 00:00:24
The idea of a reusable space shuttle that could launch like a rocket and land like an 00:00:28
airplane was appealing and would soon change the way astronauts were traveling into space. 00:00:33
The space shuttle was born on January 5, 1972, when President Richard Nixon authorized the 00:00:38
development of reusable vehicles for space exploration. 00:00:44
The project became known officially as the Space Transportation System, or STS. 00:00:47
It was based on a piloted spacecraft boosted into orbit by a reusable launch vehicle that 00:00:54
could return to Earth like an airplane, ready to be used again on short notice. 00:00:59
This new vehicle consisted of three primary elements, a delta-winged orbiter spacecraft, 00:01:04
two solid rocket boosters, and one external fuel tank. 00:01:15
Over a ten-year span, five orbiters were built, including the test vehicle named Enterprise 00:01:26
and the four space orbiters Columbia, Discovery, Atlantis, and Challenger. 00:01:31
On April 12, 1981, after years of testing and construction, the first shuttle, Columbia, 00:01:41
reached orbit piloted by astronauts John Young and Robert Crippen. 00:01:47
The first four shuttle flights were collectively called the Orbital Flight Test Program and 00:01:51
demonstrated how the spacecraft performed under real spaceflight conditions. 00:01:56
During these first four flights, NASA tested the shuttle as a launch vehicle, habitat for 00:02:01
crew members, freight handler, instrument platform, and aircraft. 00:02:05
After the fourth landing, NASA declared the shuttle ready for operation. 00:02:10
Since that time, the shuttle program has performed well over 100 missions and has accomplished 00:02:18
a number of monumental achievements. 00:02:23
In June 1983, Sally Ride became the first American woman in space. 00:02:26
The shuttle launched the Magellan spacecraft to Venus, the Galileo spacecraft to Jupiter, 00:02:31
and the Ulysses spacecraft to study the sun. 00:02:36
The shuttle also has deployed the Hubble Space Telescope, the Gamma Ray Observatory, 00:02:39
and the Upper Atmosphere Research Satellite. 00:02:44
Another key milestone came in 1998 when astronaut John Glenn, the first American to orbit the 00:02:48
Earth, returned as the oldest man ever to reach space as a member of the crew of Discovery 00:02:53
on a nine-day mission. 00:02:58
The shuttle has also been instrumental in constructing and outfitting the International 00:03:00
Space Station while also being used to carry large payloads to and from orbit and perform 00:03:04
servicing missions on satellites. 00:03:08
The design, now approaching its third decade, is still state-of-the-art in many areas, including 00:03:11
computerized flight control, airframe design, electrical power systems, thermal protection 00:03:16
systems, and main engines. 00:03:22
Even though the sophisticated shuttle program suffered the devastating losses of the Columbia 00:03:24
and the Challenger, its successful missions have made great strides in space travel and 00:03:29
exploration during its short history. 00:03:33
More than 100 documented NASA technologies from the space shuttle are now incorporated 00:03:36
into the tools we use, the foods we eat, and the biotechnology and medicines used to improve 00:03:41
health. 00:03:46
Although plans are now in the works to retire the fleet, the space shuttle program will 00:03:47
forever hold a special place in the history of space travel, not only for its unique design, 00:03:52
but for the history and technologies it brought to all of us. 00:03:57
The space shuttle has been one of the most valuable and important tools in our quest 00:04:02
to increase our understanding of space. 00:04:06
It is scheduled to go out of service in the near future, being replaced by the new Crew 00:04:08
Exploration Vehicle. 00:04:12
Up next, we'll find out exactly how sonic booms work, but first... 00:04:14
Did you know Enterprise, the first space shuttle test vehicle, was originally to be named Constitution 00:04:19
in honor of the U.S. Constitution's Bicentennial? 00:04:25
However, viewers of the popular TV science fiction show Star Trek started a write-in 00:04:28
campaign urging the White House to change the name to Enterprise. 00:04:32
Designated OV-101, the newly named Enterprise was rolled out of the assembly facility on 00:04:36
September 17, 1976 to begin its work as a flying test bed. 00:04:42
Although it never flew in space, the Enterprise flew eight captive flights attached to the 00:04:47
747 shuttle carrier and five free flights that landed at Edwards Air Force Base. 00:04:52
The Enterprise was enormously successful helping test and prove technologies that would be 00:04:57
needed in future space shuttles. 00:05:02
In November 2003, Enterprise was moved to the Smithsonian's Stephen F. Udvar-Hazy Center 00:05:04
near Washington Dulles Airport, where it is now on permanent public display. 00:05:10
