Chandrayaan 2, the second Indian lunar mission, is expected to enter today's orbit (20 August), one of the few remaining critical milestones in the mission before the spaceship tries to soft-land on the moon on september 7th.
Currently, the Composite Chandrayaan 2 completes its work lunar transfer phase, which will bring the probe sufficiently close to the moon so that it can pass into the orbit of the moon using the power of its propellers. This maneuver will allow him to break with the gravitational pull of the Earth and fall into the gravity of the moon.

When the moon has reached its peak – its farthest point on Earth – the Chandrayaan 2 Embedded thrusters will operate for a predetermined period of time, generating just enough thrust to slow down.lunar capture& # 39; phase. This controlled transfer event – freeing itself from the orbit of Earth's influence and in that of the Moon – will run for several hours, the end of which is estimated at 8:30 pm ET. East, August 20th.
The critical step will require that liquid apogee engines (thrusters) are triggered in the opposite direction to the spacecraft's motion, which will slow it down in a way "retrofiringThis allows the spacecraft to fall under the influence of the orbit of the moon.
The position of the moon with respect to the Earth and that of the Earth with respect to the Sun being in constant evolution, the intersection of The path of Chandrayaan 2 with the moon was predicted and planned well in advance.

Once the lunar capture or the entry of the spacecraft into lunar orbit completed, the mission phase, lasting two weeks (linked to the moon), will begin. This is an important part of the orbiter's mission: to monitor for the first time his one-year-old house, to ensure that his instruments are not damaged during the journey, and a Thorough examination of the landing site of the Vikram lander south of the moon. Polar region.
Chandrayaan 2 should do its long awaited downhill and motorized landing on September 7th in what the ISRO chief describes as15 minutes of terror& # 39 ;.
