ISRO found location of Vikram lander | Is there any hope for re-establishing communication with lander?


It’s a great news for all that we've found the location of the Vikram Lander on lunar surface & orbiter has clicked a thermal image of Lander. But there is no communication yet.

ISRO scientists are trying to have contact and they have said that it will be communicated soon.

After losing communication from lander as after the altitude of 2.1 km ISRO chairman K Sivan said that they will  trying to establish communication with Vikram lander and will keep trying for next 14 days.

And here we have latest updates from ISRO about finding the exact location of Lander on lunar surface also the orbiter has clicked the thermal image of Vikram lander said ISRO chairman.

ISRO Chief K Sivan said that “ We've found the location of the Vikram Lander on lunar surface & orbiter has clicked a thermal image of Lander. But there is no communication yet. We are trying to have contact. It will be communicated soon.”

ISRO will keep trying to establish contact with the Vikram lander for the next 14 days, and that information coming in from the Orbiter would be crucial.

Is there any hope for re-establishing the communication with lander?

Although according to scientists the Vikram lander was programmed in such a way that at the stage when communication was lost at altitude of 2.1 km Lander was on self operator mode. So, it is hoped that lander could be landed safely.

According to ex-ISRO Chief Lander may not have crash-landed.
While there is no official verdict about the lander's condition, not everyone is convinced that the landing ended in a crash.

ISRO Director D Sasikumar had this to say: "We have to find out from the communication data whether it is a soft landing or it is a crash landing.

In my opinion, it is not a crash landing because the communication channel is on between the lander and the orbiter. It should be intact. So, let us hope after the analysis done, we may be able to get the final figure."

If the lander has landed safely without any damage and in the proper angle then there is very much chances to re-establish communication with Vikram lander.

And if communication will establish again then the Pragyan rover which is housed inside the Vikram lander will also perform its job properly.

Isro further said that the success criteria was defined for each and every phase of the mission and till date 90 to 95 per cent of the mission objectives have been accomplished and will continue to contribute to lunar science, notwithstanding the loss of communication with the lander.

What Was The Purpose Of Vikram Lander?

The lander of Chandrayaan-2   is named Vikram after Dr Vikram A Sarabhai, the father of the Indian space programme. It is designed to function for one lunar day.

Vikram has the capability to communicate with IDSN at Byalalu near Bengaluru, as well as with the Orbiter and Rover. The Lander is designed to execute a soft landing on moon.

Lander's Payload Includes :-

1. Lander’s instrument for Lunar seismic activity will examine the earthquake movement on the sight;

2. Surface thermo- physical experiment will study the thermal conductivity of the moon; and
3. Langmuir probe will study the surface of the Moon

Although the lander also has a Rover which was to be operated after landing safely. Rover named Pragyan also has to perform several tasks .

Chandrayaan-2  rover is a six-wheeled robotic vehicle Pragyan can travel up to 500 metres and leverages solar energy for its functioning. It can only communicate with the Lander. Pragyan weights just 27 kg.

Rover's Payload Includes :-

1. Rover’s Alpha particle x-ray spectrometer will do detail analysis of Moon’s surface; and

2. Leaser induced breakdown spectroscope will test the surface composition of moon near the landing sight.

"The last part of the operation was not executed in the right manner. It was in that phase that we lost link with the lander, and could not establish contact subsequently," said K Sivan.

The ISRO chief had earlier said the final minutes of the soft landing were the most tricky, calling them "15 minutes of terror".


"This is a very complex process and it is new for us. It is a complex process even for those who have already done it. We are doing this for the first time, so it will be fifteen minutes of terror for us," he said.
