Chandrayaan-2 is closer to Moon with Orbit Change

The Indian Space Research Organization (ISRO) said on Friday that the fourth lunar bound orbit manoeuvres for the Chandrayaan-2 spacecraft, presently in the lunar orbit for its Moon rendezvous, was effectively conducted.

 
The ISRO said in an update that on 30th August 2019, the fourth Lunar bound orbit manoeuvres for Chandrayaan-2 spacecraft was carried out effectively, starting at 1818 hrs IST as scheduled, using the onboard propulsion system. The manoeuvres length was 1155 seconds. The successful orbit is 124 km x 164 km.
 
The next manoeuvres of the Lunar bound orbit is planned for 1st September. In a significant milestone for India's second Moon mission, by conducting Lunar Orbit Insertion (LOI) manoeuvres, the Chandrayaan-2 space probe effectively joined the lunar orbit on 20th August. On Sunday, there will be another orbit manoeuvres to get the spacecraft into its final orbit, crossing the lunar pole at a distance of about 100 km from the surface of the Moon.
 
Consequently, ISRO said that the lander would separate from the Orbiter (on 2nd September) and enter an orbit across the Moon of 100 km X 30 km.
 
On 7th September 2019, it would then conduct a sequence of complicated braking manoeuvres on soft soil in the Moon's southern polar region.
 
ISRO Chairman K Sivan said that the suggested soft landing on the Moon was going to be a "frightening" moment because it was something ISRO hadn't done before, while the LOI manoeuvres was taken out effectively during the Chandrayaan-1 mission.
