IceCube was built to map ice clouds globally. It had a submillimeter radiometer to overcome the limitation of ice particles in clouds being opaque in the infrared and visible spectrums. [5] [7] It was made to demonstrate a 833-gigahertz submillimeter-wave receiver as part of a technology demonstration mission. [3] [4] [8]
A satellite being propelled into place, into a stationary orbit, is first fired to a special equatorial orbit called a "geostationary transfer orbit" (GTO). [1] Within this oval-shaped ( elliptical ) orbit, the satellite will alternately swing out to 22,300 miles (35,890 km) high and then back down to an altitude of only 100 miles (160 km ...
The Quasi-Zenith Satellite System (QZSS) is a four-satellite system that operates in a geosynchronous orbit at an inclination of 42° and a 0.075 eccentricity. [26] Each satellite dwells over Japan, allowing signals to reach receivers in urban canyons then passes quickly over Australia. [27]

ICESat-2 (Ice, Cloud, and Land Elevation Satellite 2), part of NASA's Earth Observing System, is a satellite mission for measuring ice sheet elevation and sea ice thickness, as well as land topography, vegetation characteristics, and clouds. [9]
Satellites in geostationary orbit. A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma.
New satellite images show the extreme melting that has taken place on the critical Greenland ice sheet, according to researchers.. The sheet is a mass of glacial land ice and is an integral part ...
The Aeronomy of Ice in the Mesosphere (AIM or Explorer 90) was a NASA satellite launched in 2007 to conduct a planned 26-month study of noctilucent clouds (NLCs). [2] It is the ninetieth Explorer program mission and is part of the NASA-funded Small Explorer program (SMEX).
