Highlights: Major milestone, says ISRO chief after Chandrayaan 2 enters moon orbit

Chandrayaan-2 Highlights: ISRO successfully placed Chandrayaan 2 spacecraft into the lunar orbit around the Moon on Tuesday.

By HT Correspondent | Aug 21, 2019 11:42 IST

Indian Space Research Organization chairman K Sivan Tuesday said Chandrayaan 2 has been successfully placed on the moon’s orbit. The Isro chief said it was a “major milestone” and the precise lunar orbit insertion maneuver was carried out at 9 am for about 30 minutes.

On the 30th day on its journey, scientists fired the on-board liquid engine of Chandrayaan 2 in a move called the Lunar Orbit Insertion to change its path and allowed it to enter the Moon’s orbit. The lander Vikram is expected to soft land on the moon on September 7, 2019.

Chandrayaan 2 lifted off on July 22, onboard Isro’s most powerful launcher, the 640-tonne rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), from the country’s only launch site Satish Dhawan Space Centre. The lift-off was aborted an hour before its launch due to a technical glitch in its first attempt, however, a week later it was successfully launched again.

K Sivan: Once the lander separates, we will monitor orbiter and lander both

Once the lander separates on September 2 we will be monitoring both the orbiter and lander, says ISRO chief.

On September 4 we will do the real manouevre of the lander for about 6 seconds: K Sivan

On September 4 we will do the real manouevre of the lander for about 6 seconds. For three days we will check the systems and on September 7 at 1.40 the lander will begin propulsion and at 1.55 am it will land. Two hours after this the ramp will touch the ground and 3.10 hours later the solar panel will be deployed and then the rover will start from the lander and then at 4 hours the rover will touch the surface, says K Sivan.

On September 2 the lander will be separated from the orbiter: K Sivan

We are going to have four more manouevres and through this the orbit will be reduced. On September 2 the lander will be separated from the orbiter. What happens is that on September 3 we will have a small manouevre for 3 seconds to ensure that the systems in the lander are normal, says K Sivan.

On 14 August at 2:21 am, a very important manoeuvre happened: K Sivan

After the launch of the mission on July 22, 5 earth bound orbits happened. On 14 August at 2:21 am, a very important manoeuvre happened. On 19th August around 2 pm the moon also got near the mission and then it entered the orbit, says K Sivan.

Chandrayaan 2 is going around moon with an inclination of 88 degrees: K Sivan

Now the Chandrayaan 2 is going around moon with an inclination of 88 degrees. In due course this orbit will be brought down and at that time the inclination will achieve 90 degrees, says K Sivan.

Today the Chandrayaan 2 mission crossed a major milestone: K Sivan

Today the Chandrayaan 2 mission crossed a major milestone. The precise lunar orbiter conducted for 30 minutes at 9 am. In order to achieve the required landing at the South pole the chandrayaan 2 had to a unique orbit. It required a 90 degree tilt, says K Sivan

Lander Vikram will soft land on Moon on September 7, 2019

Today (August 20, 2019) after the Lunar Orbit Insertion (LOI), Chandrayaan2 is now in Lunar orbit. Lander Vikram will soft land on Moon on September 7, 2019.

Chairman, ISRO, will brief media today at 11:00 am

Dr. K. Sivan, Chairman, ISRO will brief media today (August 20, 2019) at 1100 hrs IST on the occasion of Lunar Orbit Insertion of Chandrayaan 2, reports ISRO’s twitter handle.

All systems on board Chandrayaan2 spacecraft are performing normal

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 Byalalu, near Bengaluru.

All systems on board Chandrayaan2 spacecraft are performing normal, ISRO said on August 14. According to ISRO, Chandrayaan2 will shed light on a completely unexplored region of the Moon, its South Pole.

“This mission will help us gain a better understanding of the origin and evolution of the Moon by conducting detailed topographical studies, comprehensive mineralogical analyses, and a host of other experiments on the lunar surface,” the space agency has said.

Chandrayaan 2 lifted off on July 22

Chandrayaan 2 lifted off on July 22, onboard Isro’s most powerful launcher, the 640-tonne rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), from the country’s only launch site Satish Dhawan Space Centre.

The mission carries 13 Indian scientific instruments for experiments. Imaging of rock will be done to find elements like magnesium, calcium and iron and also for signs of water. Mission will also study the exosphere of the moon. Read full story here.

Two orbit manoeuvres will be performed on the lander

Two orbit manoeuvres will be performed on the lander before the initiation of powered descent to make a soft landing on the lunar surface on September 7, ISRO said. Chandrayaan2 had entered the Lunar Transfer Trajectory on August 14 after final orbit raising manoeuvre of the spacecraft was successfully carried out.

Chandrayaan 2 moves into lunar orbit on Tuesday

In a significant step for India’s Moon mission, ISRO will fire the liquid engine of Chandrayaan 2 -- India’s second lunar mission -- on Tuesday to insert the spacecraft into a lunar orbit, 29 days after it was launched.

“It’s tomorrow morning (tentatively between 8.30 am and 9.30 am). It’s challenging,” Chairman of Indian Space Research Organisation (ISRO) K Sivan told PTI on Monday on the operation to put Chandrayaan 2 in an orbit around the Moon.
