Kalpana-1 was the first dedicatedmeteorological satellite launched by theIndian Space Research Organisation usingPolar Satellite Launch Vehicle on 12 September 2002. The satellite is three-axis stabilized and is powered bysolar panels, getting up to 550 watts (0.74 hp) of power. The METSAT bus was used as the basis for the Chandrayaan lunar orbiter mission of 2008.

History

[edit]

Originally known as MetSat-1, the satellite was the first launched by thePSLV-C4 into theGeostationary orbit. On February 5, 2003, it was renamed to Kalpana-1 by theIndian Prime MinisterAtal Bihari Vajpayee in memory ofKalpana Chawla—an Indian bornNASAastronaut who perished in theSpace Shuttle Columbiadisaster.

The satellite features a Very High Resolution scanningRadiometer (VHRR), for three-band images (visible,infrared, andthermal infrared) with a resolution of 2 km × 2 km (1.2 mi × 1.2 mi), and a Data RelayTransponder (DRT) payload to provide data to weather terrestrial platforms.[3] Its mission were to collect data in layer ofclouds,water vapor, andtemperature of theatmosphere and to establish a small satellite I-1000 bus system which can meet the exclusive service requirements of a meteorological payload for earth imageries

Kalpana-1 went out of service in mid-2018.[5]
