Launch of Space Shuttle Atlantis on STS-125, the last Hubble servicing flight. Nine crewed launches occurred in 2009, the most since 1997. STS-119, using Space Shuttle Discovery, was launched on 15 March. It installed the last set of solar arrays on the International Space Station.
Wide-field Infrared Survey Explorer (WISE, observatory code C51, Explorer 92 and MIDEX-6) was a NASA infrared astronomy space telescope in the Explorers Program launched in December 2009. [2][3][4] WISE discovered thousands of minor planets and numerous star clusters. Its observations also supported the discovery of the first Y-type brown dwarf ...
This phase was successfully completed by January 2008 at NASA- Armstrong Flight Research Center. [36] On December 18, 2009, the SOFIA aircraft performed the first test flight in which the telescope door was fully opened. This phase lasted for two minutes of the 79-minute flight.
Launched on June 18, 2009, [11] in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, [12] LRO was the first United States mission to the Moon in over ten years. [13] LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program.
On December 18, 2014, NASA announced that the K2 mission had detected its first confirmed exoplanet, a super-Earth named HIP 116454 b. Its signature was found in a set of engineering data meant to prepare the spacecraft for the full K2 mission. Radial velocity follow-up observations were needed as only a single transit of the planet was detected.
The Space Shuttle was a partially reusable spacecraft operated by the US National Aeronautics and Space Administration (NASA). [ 3 ] : 5, 195 It flew for the first time in April 1981, [ 4 ] : III–24 and was used to conduct in-orbit research, [ 4 ] : III–188 and deploy commercial, [ 4 ] : III–66 military, [ 4 ] : III–68 and scientific ...
On February 10, 2009, two communications satellites —the active commercial Iridium 33 and the derelict Russian military Kosmos 2251 —accidentally collided at a speed of 11.7 km/s (26,000 mph) and an altitude of 789 kilometres (490 mi) above the Taymyr Peninsula in Siberia. [1][2][3][4][5][6] It was the first time a hypervelocity collision ...
This timeline of artificial satellites and space probes includes uncrewed spacecraft including technology demonstrators, observatories, lunar probes, and interplanetary probes. First satellites from each country are included. Not included are most Earth science satellites, commercial satellites or crewed missions.
