Chandrayaan-2 performs 3rd lunar-bound orbit maneuver; landing in 11 days

India's second lunar expedition -- would shed light on a completely unexplored section of the Moon, its South Polar region.

Business Standard : With just 11 days to go for its moon landing, the Indian Space Research Organisation on Wednesday said it has successfully performed the third lunar-bound orbit maneuver for Chandrayaan-2 spacecraft.

All spacecraft parameters were normal, the city-headquartered space agency said after the maneuver on the spacecraft that is currently in the lunar orbit for its rendezvous with the Moon.

"Third Lunar bound orbit maneuver for Chandrayaan-2 spacecraft was performed successfully today (August 28, 2019) beginning at 0904 hrs IST, using the onboard propulsion system. The duration of the maneuver was 1190 seconds. The orbit achieved is 179 km x 1412 km," ISRO said in an update.

"All spacecraft parameters are normal. The next Lunar bound orbit maneuver is scheduled on August 30, 2019 between 1800 - 1900 hrs IST," it said.

In a major milestone for India's second Moon mission, theChandrayaan-2spacecraft had successfully entered the lunar orbit on August 20 by performing Lunar Orbit Insertion (LOI) maneuver.

After performing second lunar bound orbit maneuver on August 21, ISRO had released two sets of pictures of moon captured by the spacecraft.

There will be two more orbit manoeuvres to make the spacecraft enter into its final orbit passing over the lunar poles at a distance of about 100 km from the Moon's surface.

ISRO has said subsequently the lander would separate from the Orbiter (on September2) and enter into a 100 km X 30 km orbit around the Moon.

Then it would perform a series of complex braking maneuvers to soft land in the South polar region of the Moon on September 7, 2019.

ISRO Chairman K Sivan has said the proposed soft-landing on the Moon is going to be a "terrifying" moment as it is something ISRO has not done before, where as LOI maneuver was successfully carried out during theChandrayaan-1 mission.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru, the space agency has said.
