List of USA satellites. This is a list of satellites and spacecraft which have been given USA designations by the United States Air Force. These designations have been applied to most United States military satellites since 1984, and replaced the earlier OPS designation. As of June 2022, USA designations have been assigned to 331 space satellites.
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 .
Explorers Program. An Explorer mission observes Sagittarius A*, the Milky Way's central black hole, flaring. The Explorers program [1] is a NASA exploration program that provides flight opportunities for physics, geophysics, heliophysics, and astrophysics investigations from space. Launched in 1958, Explorer 1 was the first spacecraft of the ...
List of NASA missions. Comparison of NASA Mercury, Gemini, Apollo, and Space Shuttle spacecraft with their launch vehicles. This is a list of NASA missions, both crewed and robotic, since the establishment of NASA in 1957. There are over 80 currently active science missions. [ 1]
The Pioneer programs were two series of United States lunar and planetary space probes exploration. The first program, which ran from 1958 to 1960, unsuccessfully attempted to send spacecraft to orbit the Moon, successfully sent one spacecraft to fly by the Moon, and successfully sent one spacecraft to investigate interplanetary space between the orbits of Earth and Venus.
Ariel 1, the first satellite from a nation besides the United States or the Soviet Union, [10] was launched aboard an American Thor-Delta rocket from Launch Complex 17A at the Cape Canaveral Air Force Station, at 18:00:00 GMT on 26 April 1962. [11] The successful orbit made Ariel 1 the first international satellite. [12]
Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather, long-term climate change, natural disasters.
