Reportedly not only Indian Space Research Organization (ISRO), National Aeronautics Space Administration (NASA) is also making attempts to elicit a response from lander vikram that is lying motionless on the Moon. Meanwhile the connection between the orbiter and vikram lander snapped on the early hours of September 7, which is when ISRO had planned its soft landing on the lunar surface. So, while ISRO has been trying to establish contact with the lander, NASA too has joined in.

Image result for NASA joins ISROs attempts to contact Vikram

A source told NASA's Jet Propulsion laboratory has beamed a radio frequency to vikram lander in order to establish contact. Reportedly "NASA/JPL is trying to contact vikram through its deep space network (DSN) as contractually agreed with ISRO".



Moreover NASA's JPL has DSN ground stations in Goldstone, South California (US), Madrid (spain) and Canberra (australia). Hence these stations are located 120 degrees apart and aim to establish contact with any satellite in deep space and each site has a minimum of four antennae, from 25 metre to 70 metre in diameter. These antennae are capable of providing continuous radio communications with multiple satellites at the same time.
