2. Disha is a twin-satellite system that will study Earth’s aeronomy, the uppermost layer of Earth’s atmosphere.
Select the correct answer using the codes given below:
Disha: It is a twin-satellite system that will study Earth’s aeronomy, the uppermost layer of Earth’s atmosphere.
Trishna: It stands for Thermal Infrared Imaging Satellite for High-resolution Natural resource Assessment. It is a joint mission of ISRO and CNES, the French space agency. It is meant for accurate mapping of land surface temperature. It is scheduled for a 2024 launch.
EOS-4 and EOS-6: These are Earth Observation Satellites. They will be launched onboard the Polar Satellite Launch Vehicle (PSLV).
NISAR [NASA-ISRO SAR] mission: It is scheduled for launch in 2023. It is optimized for studying hazards and global environmental change and can help manage natural resources better and provide information to scientists to better understand the effects and pace of climate change.
X-ray Polarimeter Satellite (XPoSat): It is an ISRO planned space observatory to study polarization of cosmic X-rays. It is planned to be launched in the second quarter of 2022. The telescope is being developed by the Indian Space Research Organisation (ISRO) and the Raman Research Institute.
Aditya-L1: It is India’s first solar mission.
Chandrayaan-3: It is a third lunar mission of ISRO. It is planned to demonstrate India’s capability of soft landing on a celestial body, with the rover then communicating with Earth via the existing orbiter from Chandrayaan-2. It is planned to be launched in the third quarter of 2022.
Shukrayaan Mission: It is expected to be launched in 2024 by ISRO. It will study Venus for four years.
