Advanced Land Observing Satellite (ALOS), also called Daichi (a Japanese word meaning "land"), was a 3810 kg Japanese satellite launched in 2006. After five years of service, the satellite lost power and ceased communication with Earth, but remains in orbit.
Advanced Land Observing Satellite-2 (ALOS-2), also called Daichi-2, is a 2,120 kg (4,670 lb) Japanese satellite launched in 2014. Although the predecessor ALOS satellite had featured 2 optical cameras in addition to L-band (1.2 GHz/25 cm) radar, ALOS-2 had optical cameras removed to simplify construction and reduce costs.
The AVNIR was a multispectral radiometer for observing the Earth in the visible and near-IR wavelengths at high spatial resolution. The AVNIR employs a Schmidt optical system and an electronic scanning CCD silicon array. The AVNIR consisted of three visible channels (0.40-0.50, 0.52-0.62, 0.62-0.72 microns) and one near-IR channel (0.82-0.92 ...
Denmark's government has proposed purchasing two new Arctic inspection vessels and increasing dog sled patrols to boost its military presence in Greenland, as U.S. President-elect Donald Trump ...

Also known as Arirang-3, 3A, and 5. LAGEOS-1 and 2: Active NASA 1976 LAGEOS 1 launched in 1976 and LAGEOS 2 launched in 1992. Used as an orbiting benchmark for geodynamical ...
operation [1]. Of those there are eight in the United States (US) [2]. In 2003 the EPA reported in the Federal Register that on average approximately seven tons of mercury were missing from each plant in the year 2000 [3]. These chlor-alkali plants have an average of fifty-six cells, each containing as much as 8,000 pounds of mercury [4] and,
ALOS-4 is further enhanced from ALOS-2 by equipping the new PALSAR-3 synthetic aperture radar, which employs the new digital beamforming SAR technology. While the observation range in spotlight mode with a resolution of 1 m x 3 m was 25 km square for ALOS-2, ALOS-4 enables observation over a 35 km square area.
[4] [5] FM3 had severe power problems since 6 July 2010. It was declared not functional since then. FM4, FM5, and FM6 have had battery aging problem. [6] The data published by the COSMIC-1 constellation has been used in weather models to improve the quality of weather forecasts. [7] On 1 May 2020, the satellite constellation was retired. [8]
