NASA to share new info about Chandran 2 Vikram Lander today


The National Aeronautics and Space Administration (NASA) will today reveal new information about ISRO’s Vikram lander on the lunar surface once its satellite crosses over the landing site.

According to a US media report, NASA's Lunar Reconnaissance Orbiter (LRO) is likely to release the images of the lander on Tuesday.

Noah Petro, the LRO's project scientist, told, "NASA will share any before and after flyover imagery of the area around the targeted Chandrayaan 2 Vikram Lander landing site to support analysis by the Indian Space Research Organisation.

Vikram, with rover Pragyan, housed inside it, hit the lunar surface after communication with the ground-stations was lost during its final descent, just 2.1 km above the lunar surface, in the early hours of Saturday.

"It had a hard-landing very close to the planned (touch-down) site as per the images sent by the on-board camera of the orbiter. The lander is there as a single piece, not broken into pieces. It's in a tilted position," an ISRO official associated with the mission claimed.

"We are making all-out efforts to see whether communication can be re-established with the lander," the official said.

Chandrayaan 2 comprises an orbiter, lander (Vikram) and rover (Pragyan). The mission life of the lander and rover is one lunar day, which is equal to 14 earth days.
ISRO refused to give up and continued to make all efforts to establish a link with the lander. ISRO Chairman K Sivan had said that the space agency would try to restore the link with the lander for 14 days, and reiterated the resolve after the orbiter's camera spotted it on the lunar surface.

However, an ISRO official said: "Unless and until everything is intact (lander), it's very difficult (to re-establish contact). Chances are less. Only if it had soft-landing, and if all systems functioned, then only communication could be restored. Things are bleak as of now."

"I will rate it (restoring link) as good," another senior official of the space agency said, raising hope that lander springing to life again is not ruled out. "But there are limitations. We have experience of recovering spacecraft (which had lost contact) in geostationary orbit. But here (in the case of Vikram), that kind of operational flexibility is not there. Already it's lying on the surface of the Moon, and we cannot reorient it. The vital thing is antennas will have to be pointed towards the ground station or the orbiter. Such an operation is extremely difficult. At the same time, chances are good and we will have to keep our fingers crossed," the official said.

The official said the lander generating power is not an issue, as it has "solar panels all around it" and it also has "internal batteries" which "are not used much." Vikram carried three payloads Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere (RAMBHA), Chandra's Surface Thermophysical Experiment (ChaSTE) and Instrument for Lunar Seismic Activity (ILSA).

As a boost to the Indian space agency’s hopes, the Japan Embassy said that they are confident that India will continue its contributions to lunar exploration, along with which Japan would proudly walk.

He said that Japan Aerospace Exploration Agency (JAXA) and ISRO are planning a Japan-India joint lunar polar exploration that will be launched in the early 2020s.
