new Delhi: Indian Space Research Organization (ISRO) scientists are yet to be contacted with Vikram Lander and Pragyan Rover sent to the moon under Chandrayaan-2 mission. Under the Chandrayaan-2 mission launched on 22 July, Vikram Lander was to land on the lunar surface on 7 September. But contact with him was lost just above the lunar surface.
Now today is the last day to contact Vikram Lander. If the scientists of ISRO could not succeed in this, then they may never be contacted. The reason behind this is that its mission life was just 14 days, which is ending today.

On the morning of September 7, attempts to reconnect with the lander, which reached the lunar surface with a hard landing, have not been successful so far. The duration of one day of the moon is equal to 14 days of the Earth. According to astronomers, the sunlight is towards the end. Later this afternoon, the south pole of the moon will sink completely into darkness.
ISRO had set the working period of Vikram Lander to 14 days in advance. Now the entire focus is on the orbiter. ISRO will achieve all its stated goals. The orbiter is 100 percent correct. All 8 payloads in the orbiter are fully active. They are working continuously as planned.
After the hard landing of Vikram Lander, ISRO had hoped that they have a period of 14 days to contact Vikram once again. In these 14 days, ISRO achieved the status of Vikram with the help of thermal optical photographs. It was found that the landing has been hard, but due to this there is no damage to its structure.
The scientists kept their expectations and ISRO continued to send signals from its Deep Space Center. The orbiter responded to the signal being sent every time, but the signal reached Vikram, but there was no response from there. In this sequence, NASA has also adopted the process of sending 24 hours of signal from the deep space center installed in different places of the world, 8 hours per space center. Despite this, success has not been achieved in this direction.
Chandrayan 2 originally envisaged two processes of experimentation. Where the orbiter was to observe 100 km from the lunar surface. The same lander and rover had to land on the land of the moon, scrape the soil there and burn it, so that information about the chemical elements present in it could be collected. But in the event of loss of contact with Vikram, this experiment can no longer be done.
In the 14 days given by ISRO, there are only a few hours left. Based on the photographs received by the scientists, on the afternoon of September 19, a long shadow was formed there. The rays of the sun are becoming unstable on the moon. In such a situation, it is easy to guess that by now there has been complete darkness. Now ISRO will have to wait for sun rise once again. After sunrise after 14 days, there is little hope that the batteries in the Vikram lander will be charged.
Certainly some experiments will not be possible after the lander leaves the hands, but Chandrayaan-2's orbiter is quite right. Its 8 payloads are doing their work properly. The cameras in the orbiter are very high resolution cameras of today's time, which can take very sharp pictures of microscopic matter. In such a situation, the orbiter is eligible that except for the use of burning the soil, all other prescribed experiments orbiter will show.
