Space ISRO to transfer SSLV to private sector The Indian Space Research Organisation (ISRO) will soon transfer its Small Satellite Launch Vehicle (SSLV) to the private sector, after conducting two development flights of the rocket that seeks to provide on-demand services to put satellites weighing up to 500 kg in a low-earth orbit. Small rockets, such as the SSLV, target nano and micro-satellites, which weigh less than 10 kg and 100 kg respectively, and offer on-demand launch services, without requiring clients to wait for larger rockets to carry them as co-passengers. Last year, the ISRO had awarded a contract to build five polar satellite launch vehicles (PSLVs), its warhorse rocket with 54 successful launches, to a consortium of Hindustan Aeronautics Limited and Larsen and Toubro. Six launch vehicles developed by the ISRO Satellite Launch Vehicle-3 (SLV-3), Advanced Satellite Launch Vehicle (ASLV), Polar Satellite Launch Vehicle (PSLV), Geosynchronous Satellite Launch Vehicle (GSLV), Launch Vehicle Mark-3 (LVM-3) and Small Satellite Launch Vehicle (SSLV) Note The SLV-3 and the ASLV have been retired
