Last hope for ISRO as it races against time!


Moreoever, the landing module comprising of Vikram and rover Pragyaan housed inside it, were created to operate only for one lunar day, which is 14 Earth days from their day of their soft-landing.

The Indian Space Research Organisation (ISRO) is yet to confirm Vikram's current status.

NASA had sent its Lunar Reconnaissance Orbiter to the south pole of the moon where Vikram is stranded, and take photographs to determine the lander's fate.

The US space agency NASA also tried establishing contact with lander Vikram by activating its deep space network - an array of worldwide space antennas. Noah Petro, LRO's project scientist at NASA's Goddard Space Flight Center said, as per the report, that the orbiter would fly over the Vikram landing site on September 17. (PTI) A NASA spokesperson had earlier said that the space agency will share any before and after flyover imagery of the area around the targeted Chandrayaan-2 landing site to support analysis by ISRO.

"Meanwhile, the National Committee of academicians and ISRO experts are analyzing the cause of communication loss with #VikramLander", tweeted ISRO.

The onboard systems of Vikram and its three payloads, besides the two payloads on board Pragyan, were not created to withstand temperatures as low as -150 to -200 degrees celsius, which lunar nights present. However, in the wee hours of the touchdown, the lander lost communication with the ground station back on Earth.

While ISRO was able to locate the Lander on the basis of some thermal images from the lunar surface, attempts to establish contact with it has been unsuccessful.

The evenings on the Moon can be freezing, particularly in the south polar district where Vikram is lying.

Chandrayaan 2 for India now means its orbiter, which is successfully orbiting around the moon in the intended orbit of 100 x 100 km. Performance of all orbiter Payloads is satisfactory, " the agency said on Thursday. ISRO added that initial trials for orbiter Payloads were completed successfully.

On July 22, the Rs 978 crore Chandrayaan-2 was launched into the space by India's heavy lift rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV Mk III) in a text book style. These included a position correction, so that its legs, which were horizontal to the lunar surface, would be pointing downwards, to enable a landing on its feet.
