A visible and infrared imaging spectrographoperating from 400 nm to 5.70 μm, with spectral resolutionof 3–7 nm, that will observe tropospheric cloud features and minor gas species on Jupiter and will investigate the composition of ices and minerals on the surfaces of the icy moons.
Icy moon. Icy moons are a class of natural satellites with surfaces composed mostly of ice. An icy moon may harbor an ocean underneath the surface, and possibly include a rocky core of silicate or metallic rocks. It is thought that they may be composed of ice II or other polymorph of water ice. [ 1] The prime example of this class of object is ...
Explorer 1 was the first satellite launched by the United States in 1958 and was part of the U.S. participation in the International Geophysical Year (IGY). The mission followed the first two satellites, both launched by the Soviet Union during the previous year, Sputnik 1 and Sputnik 2. This began a Space Race during the Cold War between the ...
The Nimbus satellites were launched aboard Thor-Agena rockets (Nimbus 1–4) and Delta rockets (Nimbus 5–7). Over a 20-year period from the launch of the first satellite, the Nimbus series of missions was the United States' primary research and development platform for satellite remote sensing of the Earth. The seven Nimbus 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 .
The United States continued other space exploration, including major participation with the ISS with its own modules. It also planned a set of uncrewed Mars probes, military satellites, and more. The Constellation program, began by President George W. Bush in 2005, aimed to launch the Orion spacecraft by 2018. A subsequent return to the Moon by ...
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.
The court in 2022 rejected a separate challenge to SpaceX's plan to deploy satellites at a lower Earth orbit than planned. In late 2022, the FCC approved SpaceX's request to deploy up to 7,500 ...
