Indian Institute of Astrophysics (IIA), Bengaluru handed over Visible Line Emission Coronagraph (VELC) payload for Aditya-L1 mission to ISRO in a ceremony held on January 26, 2023 at the Centre for Research and Education in Science and Technology (CREST) Campus, Hosakote, near Bengaluru. VELC payload was designed and realised at CREST campus. The payload was handed over to Director, U R Rao Satellite Centre (USRC) by Director, IIA in the presence of Chairman, ISRO/ Secretary, DOS Shri S Somanth. Project Director of Aditya-L1 Smt. NigarShaji, and Principal Investigator of VELC Dr. B Raghavendra Prasad were present on the occasion. The payload would be integrated to the satellite at URSC.
VELC has a mechanism to occult the solar disc to separate and discards the light from the disk.The light from the Corona is captured by the coronagraph for further processing. VELC aims to collect the data for solving how the temperature of the corona can reach about a million degrees while the Sun’s surface itself stays just over 6000 degrees Centigrade. For this, the payload targets at the continuous observations of the Corona, right from its lowermost boundary upwards after having discarded the bright light from the solar disc.
VELC weighs 90 kg and is 1.7 m x 1.1 m x 0.7 m in dimension.
