Chandrayaan-2 update: Lunar Orbit Insertion

Lunar Orbit Insertion (LOI) maneuver was completed successfully today (August 20, 2019) at 0902 hrs IST as planned, using the onboard propulsion system. The duration of maneuver was 1738 seconds. With this, Chandrayaan-2 was successfully inserted into a Lunar orbit. The orbit achieved is 114 km x 18072 km.

Following this, a series of orbit maneuvers will be performed on Chandrayaan-2 spacecraft to enable it to enter its final orbit passing over the lunar poles at a distance of about 100 km from the Moon's surface.

Subsequently, the lander will separate from the Orbiter and enters into a 100 km X 30 km orbit around the Moon. Then, it will perform a series of complex braking maneuvers to soft land in the South polar region of the Moon on September 7, 2019.

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. All the systems of Chandrayaan-2 are healthy.

The next Lunar bound orbit maneuver is scheduled tomorrow (August 21, 2019) between 1230-13:30 hrs IST.

Chandrayaan-2: Moon landing at 1.55am September 7
Chethan Kumar | TNN | Upd ated: Aug 20, 2019, 9:36 IST

BENGALURU: Having successfully entered the lunar orbit on Tuesday, Chandrayaan-2 is all se t to for Moon landing at 1.55am on September 7, as per Isro's current estimates, the space agency's chairman K Sivan said.

"Today, we've crossed a major milestone. The precise LOI (Lunar Orbiter Insertion) manoeuvre carried out at about 9am for about 30 minutes has put Chandrayaan-2 in the desired orbit perfectly. In order to achieve the soft-landing on September 7, there's a unique requirement. The inclination of spacecraft needed to achieve an inclination of 90 Degrees.," Sivan said.

As of Tuesday Chandrayaan-2 has an inclination of 88 Degrees. "Right now Chandrayaan-2 is in an elliptical orbit, we'll bring it down to 100kmX100km circular orbit by performing four more manoeuvres. And then again to a 100kmX30km. By this time we'll have the inclination of 90 degree," Sivan added.

After these four manoeuvres, on September 2, lander will be separated from the orbiter. "Until now, orbiter was the focus and all manoeuvres were carried out by onboard systems of orbiter. From September 2, it will all be done on Lander systems," Sivan said.

He added that on September 3, a short three-seconds health check will be performed on the lander. After that, the next day, the de-orbit manoeuvre will be done for 6.5 seconds. At this moment, the lander will be in a 35kmX97km orbit and the remaining time before the final descent, various parameters will be checked.

"On September 4, at 1.40am (IST) the powered descent will start, and at about 1.55am, the lander will make the touchdown. Then we'll deploy the ramp, which will touch the lunar surface after which solar panels will be deployed. And, about 4 hours after the lander's landing, the rover will come out," Sivan said.

Images of Lunar Surface captured by Terrain Mapping Camera -2 (TMC-2) of Chandrayaan 2

Lunar surface imaged by Terrain Mapping Camera 2 (TMC-2) on 23rd August 2019 at an altitude of ~4375 km showing impact craters such as Jackson, Mitra, Mach and Korolev.


Jackson is an impact crater located in the northern hemisphere of the far side of the Moon.  It is a 71 km dia crater at 22.4°N and 163.1°W (shown in the inset).   The interesting feature at the western outer rim of Mach crater is another impact crater, Mitra (92 km dia).  It is named after Prof. Sisir Kumar Mitra, who was an Indian physicist and Padma Bhushan recipient known for his pioneering work in the field of ionosphere and Radiophysics. The Korolev crater seen in the image is a 437 km crater which has several small craters of varying sizes.

Lunar surface imaged by Terrain Mapping Camera 2 (TMC-2) on 23rd August 2019 at an altitude of ~4375 km showing impact craters such as Sommerfeld and Kirkwood.


Sommerfeld is a large impact crater located in the farside northern latitudes of the Moon.  It is a 169km dia crater at 65.2°N and 162.4°W.  It has relatively flat interior surrounded by a ring mountain and a number of smaller craters lie along the rim edge.  The crater is named after Dr. Arnold Sommerfeld who is a German physicist pioneered in the field of atomic and quantum physics.  North east to this crater lies the Kirkwood crater named after the American astronomer Daniel Kirkwood, another well-formed impact crater which is approximately 68 km dia.

Lunar north polar region imaged by Terrain Mapping Camera 2 (TMC-2) on 23rd August 2019 at an altitude of ~4375 km showing impact craters such as Plaskett (109km), Rozhdestvenskiy (177km) and Hermite (104 km ; one of the coldest spots in the solar system ~ 25 deg K).
