| The satellite is planned to be launched onboard GSLV Mk II rocket.
The proposed orbit is expected to be around 500 x 60,000 km around Venus. This orbit is likely to be reduced gradually, over several months to a lower apoapsis (farthest point). VenusVenus is often described as the “twin sister” of the Earth because of the similarities in size, mass, density, bulk composition, and gravity. It is believed that both planets share a common origin, forming at the same time out of a condensing nebulosity around 4.5 billion years ago. Venus is around 30 percent closer to the Sun as compared to Earth resulting in much higher solar flux. XPoSatThe X-ray Polarimeter Satellite (XPoSat) is a planned space observatory to study the polarization of cosmic X-rays. It is planned to be launched in 2021 and to provide a service time of at least five years. The telescope is being developed by the Indian Space Research Organisation (ISRO) and the Raman Research Institute. POLIX will study the degree and angle of polarisation of bright X-ray sources in the energy range of 5-30 keV. The spacecraft will be placed in a circular 500-700km orbit. It will study neutron stars, supernova remnants, pulsars and regions around black holes. Cartosat-3ISRO has launched Cartosat-3 and 13 commercial nanosatellites into Sun Synchronous orbit from Satish Dhawan Space Centre (SDSC), Sriharikota. Cartosat-3 is an earth-observation remote sensing satellite that will replace the Indian Remote Sensing (IRS) series. So far, ISRO has orbited 8 Cartosats since 2005. Remote sensing is the science of obtaining information about objects or areas from a distance, typically from aircraft or satellites. The 13 commercial nanosatellites are from the USA, which is the first commercial order for New Space India Limited, the commercial arm of ISRO which was formed in March 2019. Cartosat-3 is a third-generation advanced earth observation satellite carried by Polar Satellite Launch Vehicle, PSLV-C47. It has the ‘sharpest eye’ of civil remote sensing satellites in the world. One of Cartosat-3’s cameras offers a ground resolution of 25 cm – it can pick up an object of a minimum of 25 cm size from a height of around 500 km. Download 2.63 Mb. Share with your friends:
