The Hubble Space Telescope was released into Earth's Orbit by the Space Shuttle Discovery.


As the U.S. Galileo spacecraft is on its way to Jupiter. It encountered Gaspra, an asteroid, that the Galileo triumphantly gathered data and images from.


The U.S. Cosmic Background Explorer spacecraft sought out the structure of the galaxy.


Endeavour was launched on a mission to repair the Hubble Space Telescope.


The first Milstar Secure Communications satellite launched.  These Geosynchronous satellites are used by battlefield commanders for strategic communications.


Aerospace giants Lockheed Corporation and Martin Marietta Corporation merged.


Galileo released its space probe, which  was bound for Jupiter and its moons.


NASA and Stanford University researchers announced a paper contending a 4 billion year old Martine meteorite was found in Antarctica in 1984. The meteorite contained fossilized traces of carbonate materials that suggested primitive life may have once existed on Mars.


The Mars Pathfinder landed alongside the Sojourner Rover.  


The Boeing Company and the McDonnell Douglas Corporation merged, keeping Boeing's name.


Globalstar, a satellite mobile telephone company, launched its first four satellites on a Delta 2 Rocket.


The Chandra X-ray Observatory, NASA's flagship base for X-ray astronomy, launched aboard the Space Shuttle Columbia.


After being mothballed in 1999, Mir descended into Earth's atmosphere and breaks over the Pacific Ocean.


The Space Shuttle Columbia disintegrated as it re-entered Earth's atmosphere, killing the crew.  Damage from insulation hitting the orbiter's leading wing on liftoff was later cited as the cause of the accident.


NASA launched the Spitzer Space Telescope aboard a Delta rocket.


The first Mars Exploration Rover, Spirit, landed on Mars.  Its twin, Opportunity, landed January 25th.


President George W. Bush advocated space exploration missions to the moon and Mars for NASA in his Vision for Space Exploration speech.


New Horizons, NASA's first-ever mission to the dwarf planet Pluto and its moons, launched atop an Atlas 5 rocket from Cape Canaveral, Florida. New Horizons flew past Jupiter one year later, which was considered to be NASA's fastest mission to date.


Discovery began a successful space station-bound mission, returning the U.S. orbiter fleet to flight status.


NASA resumed construction of the International Space Station with the launch of the shuttle Atlantis.  Atlantis' launch occurred after nearly four years without a station construction flight.


China downed one of its weather satellites, Fengyun-1C, with a ground launched missile.  In doing so, China joined Russia and the United States. These were the only nations to have successfully tested anti-satelite weapons.  


NASA's Space Shuttle, Endeavour, launched toward the International Space Station on the STS-118 construction mission. The shuttle crew included teacher-astronaut Barbara Morgan, NASA's first educator spaceflyer. 


Dawn, the first ion-powered probe to visit two celestial bodies in one attempt, launched on an eight-year mission to the asteroid Vesta and dwarf planet Ceres, the two largest space rocks in the solar system.


NASA astronaut Peggy Whitson, the first female commander of the International Space Station, prepared for a  launch on October 10th with her Expedition 16 crew mate Yuri Malenchenko. They were commanding a jointed space station construction mission.
