About the STS-99 Mission
| Type | Earth Science |
|---|---|
| Orbit | Low Earth Orbit |
| Launch Cost | $450,000,000 |
STS-99 was a Space Shuttle mission using Endeavour, that launched on 11 February 2000 from Kennedy Space Center, Florida. The primary objective of the mission was the Shuttle Radar Topography Mission (SRTM) project. This was also the last solo flight of Endeavour; all future flights for Endeavour became devoted to the International Space Station.
Launch Pad & Location
Launch Complex 39A
Kennedy Space Center, FL, USA
| Launches | 224 |
|---|---|
| Orbital Launch Attempts | 223 |
| Total Launches | 283 |
The John F. Kennedy Space Center, located on Merritt Island, Florida, is one of NASA's ten field centers. Since 1968, KSC has been NASA's primary launch center of American spaceflight, research, and technology. Launch operations for the Apollo, Skylab and Space Shuttle programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Space Force Station (CCSFS).
NASA Space Shuttle Rocket
The Space Shuttle is a retired, partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS). Five complete Space Shuttle orbiter vehicles were built and flown on a total of 135 missions from 1981 to 2011.

Mission Spacecraft
Space Shuttle Endeavour
Space Shuttle Endeavour (OV-105) was the spacecraft used for this mission. It is a NASA Spaceplane designed for Carrying a crew of 7 astronauts along with cargo to Low Earth Orbit. and traveled to Low Earth Orbit.
Space Shuttle Endeavour (Orbiter Vehicle Designation: OV-105) is a retired orbiter from NASA's Space Shuttle program and the fifth and final operational shuttle built. It embarked on its first mission, STS-49, in May 1992 and its 25th and final mission, STS-134, in May 2011. STS-134 was expected to be the final mission of the Space Shuttle program, but with the authorization of STS-135, Atlantis became the last shuttle to fly. The United States Congress approved the construction of Endeavour in 1987 to replace Challenger, which was lost in 1986. Structural spares built during the construction of Discovery and Atlantis were used in its assembly. NASA chose, on cost grounds, to build Endeavour from spares rather than refitting Enterprise. The Space Shuttle was a partially reusable LEO spacecraft system operated by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. The first of four orbital test flights occurred in 1981, leading to operational flights in 1982. In addition to the prototype whose completion was cancelled, five complete Shuttle systems were built and used on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST); conducted science experiments in orbit; and participated in construction and servicing of the International Space Station. The Shuttle fleet's total mission time was 1322 days, 19 hours, 21 minutes and 23 seconds. 14 days
