Chandrayaan-2: Third Orbit-Raising Activity Completed Successfully India’s second Moon mission Chandrayaan-2 lifts off onboard GSLV Mk III-M1 launch vehicle from Satish Dhawan Space Center at Sriharikota in Andhra Pradesh. The third orbit raising activity for Chandrayaan-2 spacecraft has been performed successfully at 3.12 p.m. on Monday, the Indian space agency said. The Indian Space Research Organisation (ISRO) said the orbit of the Chandrayaan-2 was raised to 276 x 71,792 km by firing the onboard motors for 989 seconds. All spacecraft parameters are normal, it said.
The fourth orbit-raising maneuver is scheduled between 2 to 3 p.m. on August 2. 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) in a textbook style. The spacecraft 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 earth-bound maneuvers, the trans-lunar insertion, lunar-bound maneuvers, Vikram’s separation from Chandrayaan-2 and touch down on the moon’s the South Pole. The ISRO said the trans-lunar insertion of Chandrayaan-2, which will send it to the moon, is scheduled on August 14. After that, the Chandrayaan-2 is scheduled to reach the moon by August 20 and the lander Vikram will land on the Earth’s sole satellite on September 7.
