Appeared in: AIIMS CRE 2025

Explanation

AstroSat is India's first dedicated multi-wavelength space observatory, a significant milestone for the country's space program.
It was launched by the Indian Space Research Organisation (ISRO) on September 28, 2015.
AstroSat's key capability is its ability to perform simultaneous multi-wavelength observations of astronomical objects, a unique feature that allows for more comprehensive data collection on cosmic phenomena.

Option B: China has its own active space program and has launched several space telescopes, but AstroSat is not one of them.
Option C: Russia, through its agency Roscosmos, has a long history in space exploration, including space observatories, but it did not launch AstroSat.
Option D: The USA's space agency, NASA, is famous for many iconic space telescopes, but AstroSat is an Indian mission.
