Meanwhile, the world’s largest space agency, the National Aeronautical and Space Administration (NASA), has sent a message of hello to contact Vikram Lander lying motionless on the lunar surface. NASA’s Jet Propulsion Laboratory (JPL), through its deep space ground station network, has sent a radio frequency to Vikram to establish contact with the lander. A NASA source confirmed this.
The source said, “Yes, NASA / JPL are trying to connect with Vikram through deep space network (DSN). For which ISRO agrees. ‘ Expectations of contact with Vikram are decreasing day by day. After 14 Earth days, on September 20-21, when there is a night on the moon, all hopes of reconnecting with Vikram will end.
Another astronaut, Scott Tillay, has also confirmed that NASA’s California-based DSN station has sent radio frequencies to the lander. Tillay came into the limelight when he discovered a missing NASA spy satellite in 2005. On sending the signal to the lander, the moon acts as a radio reflector and sends a small portion of the signal back to the earth that can be detected after traveling 800,000 kilometers.
On Wednesday, ISRO said that its lander contact with Vikram was broken at 335 meters, not at an altitude of 2.1 kilometers from the lunar surface. This is revealed by the picture released from ISRO’s mission operation complex. Even at an altitude of 4.2 kilometers above the lunar surface, the Vikram lander deviated slightly from its predetermined path but was soon corrected. After this, when the Vikram lander of Chandrayaan-2 reached an altitude of 2.1 km from the lunar surface, it deviated from its path and started on another path.
