"In 2016 end or 2017 the Major Atmospheric Cherenkov Experiment (MACE) telescope would be ready. It will be operated from Mumbai because in that minus 40 degree temperatures in Ladakh you cannot have many people all throughout the year. From Mumbai it will be operated at all times," Basu told reporters here.
He said the gamma ray telescope, the biggest in the northern hemisphere having a diameter of 45 metres, is going to detect Cherenkov radiation coming from cosmic particles.
Ladakh's Hanle village where the telescope is coming up is located at about 4500 meters above mean sea level.
BARC has entrusted the Electronics Corporation of India, Hyderabad, to built the telescope.
