印度ISRO正式承认未能登陆月球着陆器

The human space research organization ISRO’s lunar lander Vikram lost communications shortly after attempting to land on the moon in September. One month after separation from the orbiter, the camera of the circumferential probe Chandrayan 2 discovered Vikram, and ISRO attempted to restore communications.

However, according to the report, ISRO confirmed that Vikram was destroyed in shock at the time of landing. At the time of landing, the brake system failed for some reason and crashed at a distance of 500m from the landing point. At the beginning of landing, Vikram slowed down from 1,863 m/sec to 146 m/sec. However, as the deceleration rocket malfunctioned, the next stage deceleration was incomplete, and the condition for the control program to start the soft-interruption stage was not met. As a result, it hit the moon’s surface without being able to slow down enough, and it was impacted by more than the design strength.

ISRO confirmed the location of Vikram and attempted to resume communication, and from October, it has also resumed communication with the cooperation of NASA. But there was no answer on the moon. Indian Prime Minister Modi admitted that the landing was actually wrong after the loss of communications, but said there was no scientific failure. However, the report was approved by the Indian government, and it can be said that the Indian government officially acknowledged the failure to land on the moon.

If Vikram had landed properly on the moon, India could be named the fourth country to successfully land on the moon. ISRO’s failure to land on the moon is still an event that reminds mankind that landing on the moon is a difficult task. In addition, although the lander was lost, ISRO is collecting scientific data on the moon using eight sensors inside Chandrayan 2 orbiting the moon. Related information can be found here .
