Scores of fake Twitter accounts of Sivan had emerged on September 7-8, shortly after his popularity peaked due to the Chandrayaan 2 mission. The battery of Vikram Lander, which is carrying the Pragyan Rover, has an expected life of 14 days, so ISRO has another 12 days to establish communication with the craft.
"#VikramLander has been located by the orbiter of #Chandrayaan2, but no communication with it yet".
Without communication to the lander, Isro will not be able to receive any data from the experiments that were to be done by the lander or the Pragyan rover, which can communicate to Earth only via the lander. The ISRO chairman, the clarificatory note said, has no personal account on any social media platform.
Devotees took part in the prayers so that contact could be established with the lander and the orbiter.
The prayers included "abishekam" (celestial bath), which was performed with several items, including honey and sandal paste and followed by a community feast (Annadhanam), a temple official said on Tuesday. The photos have not yet been released, but according to ISRO's chief, Kailasavadivoo Sivan, the lander has been seen near the targeted landing site and apparently in one piece.
The ISRO is understood to be trying to call Vikram via the orbiter link. However, it would provide new information on the Moon's scarcely-explored south pole region. Up to (lunar) orbit insertion, we did not have any flaw.
In 2014, India became only the fourth nation to put a satellite into orbit around the Red Planet, and in 2017 India's space agency launched 104 satellites in a single mission.
Meanwhile, flawless and precise launch and efficient management of the Chandrayaan-2 mission - till the lander "Vikram" lost communication with ground-stations -, has paid rich dividends to the ISRO on the orbiter front. The rover would not be functional until communication with the lander is re-established. Also, India would have been the first country to reach close to the lunar South Pole.
