Landsat 8 is an American Earth observation satellite launched on 11 February 2013. It is the eighth satellite in the Landsat program; the seventh to reach orbit successfully. Originally called the Landsat Data Continuity Mission (LDCM), it is a collaboration between NASA and the United States Geological Survey (USGS). NASA Goddard Space Flight Center in Greenbelt, Maryland, provided development, mission systems engineering, and acquisition of the launch vehicle while the USGS provided for development of the ground systems and will conduct on-going mission operations. It comprises the camera of the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS) which can be used to study earth surface temperature and is used to study global warming.
A GPS satellite is a satellite navigation used by the NAVSTAR Global Positioning System (GPS). The first satellite in the system, Navstar 1, was launched on 22 February 1978. The GPS satellite constellation is operated by the 2d Space Operations Squadron (2SOPS) of Space Delta 8 of the United States Space Force.
IRS-1C was the fourth remote sensing Indian satellite built, and designed by Indian Space Research Organization (ISRO). IRS-1C is first second-generation operational Remote Sensing Satellite. The satellite carries payloads with enhanced capabilities like better spatial resolution additional spectral bands, improved repetitivity and augment the remote sensing capability of the existing IRS-1A and IRS-1B.
IRS-1A, the first of the series of indigenous state-of-art remote sensing satellites, was successfully launched into a polar sun-synchronous orbit on 17 March 1988 from the Soviet Cosmodrome at Baikonur. IRS-1A carries three cameras, LISS-1, LISS-2A and LISS-2B with resolutions of 72.5 metres (238 ft) and 36.25 metres (118.9 ft) respectively with a swath width of about 140 kilometres (87 mi) during each pass over the country. Undertaken by the Indian Space Research Organisation (ISRO). It was a part-operational, part-experimental mission to develop Indian expertise in satellite imagery.
Landsat 9 is a planned Earth observation satellite, scheduled for launch in September 2021. NASA is in charge of building, launching, and testing the system, while the United States Geological Survey (USGS) will process, archive, and distribute its data. It will be the eighth satellite in the Landsat series, as Landsat 6 failed to reach orbit. In September 2020, United Launch Alliance is planning for a September 2021 launch on an Atlas V 401 launch vehicle, which will lift off from Space Launch Complex-3E at Vandenberg Air Force Base. The Critical Design Review (CDR) was completed by NASA in April 2018, and Orbital ATK was given the go-ahead to manufacture the satellite.
