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 ...
Lunar IceCube. Lunar IceCube is a NASA nanosatellite orbiter mission that was intended to prospect, locate, and estimate amount and composition of water ice deposits on the Moon for future exploitation. [2] It was launched as a secondary payload mission on Artemis 1 (formerly known as Exploration Mission 1), the first flight of the Space Launch ...
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 ...
Water ice seems to be ubiquitous on its surface, with a mass fraction of 50–90 percent, [9] significantly more than in Ganymede as a whole. Near-infrared spectroscopy has revealed the presence of strong water ice absorption bands at wavelengths of 1.04, 1.25, 1.5, 2.0 and 3.0 μm. [50]
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, ( cosmic) - radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and ...
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 GOES-R series is a four-satellite program (GOES-R, -S, -T and -U) intended to extend the availability of the operational GOES satellite system through 2036. [10] GOES-R launched on 19 November 2016. [9] It was renamed GOES-16 upon reaching orbit. Second of the series GOES-S, was launched on 1 March 2018.
Lunar water. These false-color images show areas where water presence is indicated in a young lunar crater on the far side, as imaged by the Moon Mineralogy Mapper aboard Chandrayaan-1. The image shows the distribution of surface ice at the Moon's south pole (left) and north pole (right) as viewed by NASA's Moon Mineralogy Mapper (M 3 ...
