It may be recalled that Indian Space Research Organisation (ISRO) is going to launch the 48th mission of the PSLV series — #PSLVC46 on 22 May 2019 (Wednesday). The space missile will be carrying an earth observation satellite #RISAT2B in the PSLV-Core Alone rocket’s fourth stage.
The missile will be launched from the First Launch Pad (FLP) of the Satish Dhawan Space Centre (SDSC) SHAR in Sriharikota, Andhra Pradesh at 05. 27 am, due to weather condition.
PSLV-C46 space mission:
The #PSLVC46 mission is ISRO’s 48 PSLV launch, and the 72nd launch vehicle mission from SDSC SHAR, Sriharikota and 36th launch from the First Launchpad, is the 14th flight of PSLV in ‘core-alone’ operation, which indicates without the use of solid strap-on motors.
The PSLV was the head of #ISRO’s spacecraft to be equipped with liquid rocket stages. In the PSLV-CA version, the spacecraft doesn’t have the six strap-on boosters that massive rockets do, and simply uses the four core stages of the PSLV to launch its payload.
The purpose of Earth observation satellites on earth:
Beginning with IRS-1A in 1988, #ISRO has propelled many operational remote sensing spacecraft. But today, India holds one of the greatest constellations of remote sensing satellites in process. Currently, there are 13 operational satellites are in Sun-synchronous orbit and 4 in Geostationary orbit. #ISRO has swooped many different machines with these satellites to store inevitable data in a diversified geographical analysis to provide to various field demands in the nation and also for global practice. The information from these satellites is utilized for various applications including agriculture, urban planning, water sources, country development, climate, mineral prospecting, forestry, and disaster control.
#RISAT2B, which means for “Radar Imaging Satellite-2B”, is the second in a set of satellites used to recognize weather conditions on Earth using radar imagery. Once operational, the satellite will be efficient of observing weather day and night, in all weather situations. #RISAT2B is located in an orbit 555 kilometers from Earth at a 37-degree inclination. It has a mission lifetime of 5 years and posses 615 kg lift-off weight with X-Band Radar payload. The main application of this satellite is to collect images which will be used in agriculture, forestry, and disaster management support.
RISAT-2 was the first satellite in the list, propelled for the purpose of surveillance. RISAT-1 was started later, to become India’s first all-weather radar imaging satellite.
Launching view open for the visitors:
Moreover, in order to present enthusiastic fans a more personalized knowledge of the rocket launch, ISRO has created preparations for the public to see the launch from the newly opened launch view gallery at SDSC, SHAR, Sriharikota.
Online registrations to view the #ISRO #PSLVC46 #RISAT2B launch live from the viewer’s gallery had opened 5 days before the launch, which amounts to 17th or 18th of May. While the last time only 1200 viewers were allowed to see the PSLV-C45 launch, but this time nearly 5000 visitors may be able to do so.
