ISRO in a tweet said 'fifth earthbound orbit raising manoeuvres for Chandrayaan2 spacecraft has been performed today at 3.04pm as planned using the onboard propulsion system for a firing duration of 1,041 seconds.'
'The orbit achieved is 276 x 142975 km', it said. All spacecraft parameters were normal. The next manoeuver is Trans Lunar Insertion (TLI), which is scheduled for August 14, 2019 between 3am and 4am. The first orbit raising was carried out on July 24 taking the spacecraft to an orbit of 230 X 45163 km, the second on July 26, the third on July 29 and the fourth on August two.
About 16 minutes from lift off from the Second Launch Pad from the SHAR Range, Chandrayaan–2 was placed into a highly elliptical orbit of 170 x 45,475 km. Post launch, further major activities included Earthbound manoeuvers, and the fifth and final was completed today.
It would be followed by Trans Lunar Insertion, Lunar bound manoeuvers, Vikram (Lander) Separation and Vikram Touch Down and Rover (Pragyan). After the Trans Lunar Insertion on August 14, it would send the Chandrayaan–2 spacecraft to the Moon. 'The spacecraft is scheduled to reach the moon by August 20', ISRO said.UNI
