RISAT-2B Successfully Launched

Indian Space Research Organisation (ISRO) has successfully launched the RISAT-2B satellite. It is an earth observation satellite which adds to India’s capability to observe the earth in all weathers and all conditions. About the Launch The RISAT or Radar Imaging Satellite is equipped with a sensor known as ‘synthetic aperture radar’ to produce ‘radar images’. ..



LIDAR stands for Light Detection and Ranging. It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges to the Earth. The technology is used to map the land and is used to measure seafloor and riverbed elevations. Two types of LIDAR are topographic and bathymetric. Topographic LIDAR typically uses ..


GRACE—FO Mission

The Gravity Recovery and Climate Experiment Follow-on (GRACE-FO) mission is a partnership between NASA and the German Research Centre for Geosciences (GFZ). GRACE-FO is a successor to the original GRACE mission, which began orbiting Earth on March 17, 2002. GRACE-FO will carry on the extremely successful work of its predecessor while testing a new technology ..


ISRO and NASA are jointly working on NISAR to launch dual frequency SAR satellite by 2021

The ISRO and NASA are jointly working on the NASA-ISRO Synthetic Aperture Radar (NISAR) mission to co-develop and launch a dual frequency (L & S Band) synthetic aperture radar satellite. This earth monitoring satellite is scheduled to be launched in 2021. In this joint mission, NASA will be responsible for design and development of L-band ..


RISAT-1 placed in final Polar Sun-synchronous orbit

India’s indigenously built Radar Imaging Satellite (RISAT-1), launched on April 26, 2012 has been placed in its final Polar Sun-synchronous Orbit. On April 27-28, 2012 the satellite’s propulsion system was used in 4 orbital manoeuvres to raise the height of the orbit of RISAT-1 to 536 km. In the coming days, various elements of the ..
