India’s second Moon spacecraft Chandrayaan-2 put into earth orbit on July 22, on Friday successfully completed its second earthbound orbit raising maneuver.
All spacecraft parameters are normal,” the Indian Space Research Organization tweeted.
The first one was performed on July 24. The Chandrayaan-2 is scheduled to reach the Moon by August 20, the Indian space agency had said on Wednesday.
According to the Indian Space Research Organisation (Isro), the first earthbound orbit-raising maneuver for Chandryaan-2 spacecraft was successfully performed on Wednesday afternoon by firing the onboard motors for 57 seconds.
On July 22, the Chandrayaan-2 was injected into an elliptical orbit of 170×45,475 km by India’s heavy-lift rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV Mk III).
The spacecraft Chandrayaan-2 comprises three segments – the Orbiter (weighing 2,379 kg, eight payloads), the lander ‘Vikram’ (1,471 kg, four payloads) and rover ‘Pragyan’ (27 kg, two payloads).
The Indian space agency said the major activities include earthbound maneuvers, Trans Lunar Insertion, Lunar bound maneuvers, the lander Vikram separation from Chandrayaan-2 and Vikram touch down on the Moon’s the South Pole. The Isro said the Trans Lunar Insertion of Chandrayaan-2 is scheduled on August 14, 2019, which will send the spacecraft to Moon. After that, the Chandrayaan-2 is scheduled to reach Moon by August 20, 2019.
According to ISRO, the lander Vikram will land on the Moon on September 7.
Originally the GSLV-Mk III rocket carrying Chandrayaan-2 was supposed to fly on July 15. Owing to a serious technical glitch the flight was postponed to July 22. There are changes in the mission schedule.
The lunar bound phase which was for 28 days for July 15 flight schedule has come down to 13 days. Initially, Vikram was planned to land on the Moon 54 days after the rocket’s lift-off and now the landing will be taking place in 48 days.
