BENGALURU: India's MarsOrbiter Mission (MOM) spacecraft, which was designed to last for six months when launched on November 5, 2013, has lost communication with the ground stations, bringing an end to its life after eight long years.Isro is working out the details of whether the spacecraft ran out of fuel and battery power, or whether communication was lost because of an automated manoeuvre while moving out of a long eclipse changing the direction of the antenna.While recovering from the eclipse, the fuel may have been exhausted.The other reason could be that while exiting the eclipse a command for a roll-spin to change direction is done, which could have caused the Earth-facing antenna to change direction.”As reported by TOI earlier, the spacecraft had handled two black-out phases during an eclipse and one white-out phase in the first year around Mars and another in the second year.“Now, we are trying to ascertain the exact reason — whether it is the exhaustion of fuel or antenna being unable to communicate — but one thing is for certain, we won’t be able to recover the spacecraft any more,” the scientist further explained."
