Full details about what happened
in those crucial minutes!

Chandrayaan-2 Mission is the second lunar mission by the Indian Space Research Organization. After Chandrayaan 1. It comprises of one Orbiter, Vikram Lander, Pragyan Rover. On 12th November 2007, The Russian Federal Space Agency And Indian Space Research Organisation Agreed to work together on the Chandrayaan-2 project. But Due to delay Russian space agency was unable to deliver the Lander even in 2015, India decided to complete the project solely.

The Schedule 

The Spacecraft initial launch was scheduled for March 2018 but was delayed to conduct tests on the vehicle. It was finally scheduled for 14th July 2019. The launch was aborted due to technical glitch and rescheduled on 22nd July at 2:43 PM IST.

Objective Of Chandrayaan-2

Chandrayaan-2

The Objective of the Chandrayaan-2 is to Demonstrate the soft landing and operating a rover on the moon surface and to study the Lunar Topography, mineralogy, elemental abundance, the lunar exosphere. Whereas the orbiter goal is to map the lunar surface and prepare the 3d map of it.

The Plan

chandrayan-2

The two landing sites were selected for a smooth landing. The primary landing site was PLS54 and the alternate landing site was ALS01.

Vikram(lander) separated from Chandrayaan-2 orbiter on 2nd September 2019 at 1:15 PM IST.and the orbiter continues to orbit the moon in its existing orbit.
The lander Vikram was to undergo two deorbit manoeuvres to prepare for the soft landing and were achieved on September 3rd and 4th. After these manoeuvres, the powered descent phase was to be done on September 7th.

Crucial Moments

The first manoeuvre Vikram will perform will be to slow it’s speed down significantly. Chandrayaan-2 lander Vikram has begun its descent towards the lunar surface.

Time 1:37 am IST

Now, Vikram was performing the ‘Rough Breaking’ a powered descent to significantly lower it’s speed as it begins its descent on to the lunar surface. The Lander was 4km away from the landing site. Rough breaking was accomplished and ‘Soft Breaking’ initiated.
There was a delay in the Chandrayaan-2’s landing on the moon. ISRO was still waiting to receive a signal from lander Vikram that it has landed on the lunar surface. There was no signal from the Chandrayaan-2’s Vikram. The landing procedure was supposed to take 15min but it’s been 30 min since the descendant but no information from the lander.

ISRO confirms the connection lost

The Indian Space Research Organisation chief K Sivan has confirmed that the contact with Chandayaan-2’s lander has been lost. The Isro chief said that the lander Vikram was descending on to the lunar surface as planned and that until 2.1 kilometres above the lunar surface, its performance was normal. But them, “lander to the ground station was lost,” Sivan said. “Data is being analyzed.”

Planned Missions ISRO

.ISRO is having 25 missions planned for 2020 and they are also working on Chandrayaan-3 which is to once again land on the lunar surface in a smooth manner.

ISRO is also working on a Manned Mission to space which is for the first time ISRO will launch astronauts into the space named as Gaganyaan.

Let’s hope for the best and wish our Indian Space Research Organization a Good Luck!
