The Indian Space Research Organization (ISRO) is studying the possibility of developing a next-generation astronomical satellite, an official said on Tuesday. ISRO’s first mission dedicated to astronomy, AstroSat, launched on September 28, 2015, with a nominal lifespan of five years, completed six years of operation on Tuesday.
“It (AstroSat) is expected to last a few more years,” said AS Kiran Kumar, who as president of ISRO at the time headed the mission team and currently chairs the space agency’s scientific committee. “We can expect other results which will be revolutionary.”
Asked about the possibility of ISRO launching AstroSat-2, he replied: “Not AstroSat-2. The next generation … the thinking continues … depending on how the planning goes … how different are envisaged “.
According to ISRO officials, data from AstroSat is widely used for the study of various fields of astronomy, from the galactic to the extra-galactic, and by users around the world.
The multi-wavelength space observatory, which has five unique X-ray and ultraviolet telescopes operating in tandem, had detected extreme UV light from a galaxy, called AUDFs01, 9.3 billion light years away. of the earth.
The discovery was made by an international team of astronomers led by Dr Kanak Saha, at the Interuniversity Center for Astronomy and Astrophysics (IUCAA), Pune and reported in “Nature Astronomy”. This team included scientists from India, Switzerland, France, the United States, Japan and the Netherlands.
AstroSat also observed for the very first time rapid variability in high-energy (especially> 20 keV) X-ray emissions from a black hole system, officials noted.
“AstroSat was a very successful mission and it produced results which are acclaimed worldwide …” said Kiran Kumar. “A large number of articles have also been published.” PTI
