The Luna programme (from the Russian word Луна "Luna" meaning "Moon"), occasionally called Lunik by western media, [1] was a series of robotic spacecraft missions sent to the Moon by the Soviet Union between 1959 and 1976.
After bouncing off the surface twice, Philae achieved the first-ever "soft" (nondestructive) landing on a comet nucleus, [14] [15] [16] although the lander's final, uncontrolled touchdown left it in a non-optimal location and orientation. [17] Despite the landing problems, the probe's instruments obtained the first images from a comet's surface ...
Mercury-Redstone 3, or Freedom 7, was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard.It was the first crewed flight of Project Mercury.
An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge equipped with propulsion systems to maintain precise position and a large landing platform.SpaceX developed these vessels to recover the first stage (also called the booster) of its launch vehicles.
Mercury-Atlas 6 (MA-6) was the first crewed American orbital spaceflight, which took place on February 20, 1962. [4] Piloted by astronaut John Glenn and operated by NASA as part of Project Mercury, it was the fifth human spaceflight, preceded by Soviet orbital flights Vostok 1 and 2 and American sub-orbital flights Mercury-Redstone 3 and 4.
The orbiter always landed at either Edwards Air Force Base, California or at the Kennedy Space Center Shuttle Landing Facility, Florida, except STS-3 at the White Sands Space Harbor in New Mexico. Similar special clearances (no-fly zones) were also in effect at potential emergency landing sites, such as in Spain and in West Africa during all ...
The Space Shuttle Discovery soon after landing: Modified Boeing 747 carrying Discovery: STS-124 comes to a close as Discovery lands at the Kennedy Space Center: Discovery ' s final touchdown on Kennedy Space Center's runway, concluding the STS-133 mission and Discovery ' s 27-year career
An ECAL/BDA abort was similar to RTLS, but instead of landing at the Kennedy Space Center, the orbiter would attempt to land at another site along the east coast of North America (in the case of ECAL) or Bermuda (in the case of BDA). Various potential ECAL landing sites extended from South Carolina into Newfoundland, Canada.
