According to the information received, the time limit for Chandrayaan-2 to contact Vikram Lander is expiring. Meanwhile, news has come that NASA's Moon Arbiter has taken pictures of the area of the moon where India lost contact with Chandrayaan-2.
A report by a NASA scientist said that NASA took several pictures on September 17 with the help of its Lunar Reconnaissance Orbiter (LRO) at the south pole of the moon. NASA is currently analyzing these photos. In the same area, an attempt was made to make a soft landing of Vikram lander under Mission Chandrayaan-2, but the contact with ISRO was lost two kilometers before Vikram's land.
The possibility of contacting Vikram Lander is only till 21 September. After that, there will be darkness in that area of the moon. Lunar Reconnaissance Orbiter (LRO) deputy project scientist John Keller confirmed in a statement that the orbiter's camera took the pictures.
Currently the LRO team will compare these photos with the old ones and analyze them to see if the lander is visible or not. These pictures were taken while the orbiter was passing through the south pole of the moon. At that time it started getting dark there. It is clear that those photos will be blurred.
Where the Vikram lander fell, it is evening in that part of the moon. After 21 September there will be no sunlight and it will be night. Nights are very cold on the moon. During the night, the temperature of this part can decrease to minus 200 degree Celsius. The electronic parts of Vikram Lander are not designed to be able to survive in this temperature. Therefore, if contact could not be established with Vikram in the next day, then its possibility will end forever.
