Orbiter’s camera is the highest resolution of any lunar mission so far “The pictures I saw this morning were truly extraordinary,” said the Principal Scientific Advisor, about the orbiter’s TMC 2 camera. It is a miniature version of the Terrain Mapping Camera used onboard the Chandrayaan 1 mission. Here’s a look at its first few images and subsequent photos, while it was still en route to the moon.

If Vikram crashed and broke up into pieces, the orbiter’s imaging won’t be very useful: Expert If the Vikram lander crash-landed and broke apart into pieces, the orbiter is unlkely to spot it, according to an ISRO scientist. “However, if the component is intact, high-resolution imaging will capture it,” he added.

Space agencies, citizens & political leaders come out in support of ISRO & the Chandrayaan 2 mission Citizens and leaders across the political spectrum have offered overwhelming support to ISRO after the agency lost contact with the lander module comprising the Lander Vikram and Rover Pragyan, a hitch in India’s ambitious space project Chandrayaan 2.

Lander may have spun out of control: Experts. Some experts think the motors fitted to the landing module might have over-performed in this last leg of its descent, giving its more thrust than needed, or a higher horizontal velocity that may have caused the lander to spin out of control.

14 – day mission to re-establish contact with lander ISRO it will try to establish contact with the Vikram lander for the next 14 days, and that information coming in from the Orbiter would be crucial.
On 7 September 2019, the day Vikram Lander was scheduled to soft-land on the lunar surface, ISRO lost contact with the lander module comprising the Lander Vikram and Rover Pragyan, which came to be ahitch in India’s ambitious space project Chandrayaan 2. However, despite the failed landing, this mission’s orbiter will still be performing various crucial tasks. Principal scientific advisor Dr Vijay Raghavan reminds us of that in along Twitter thread.
Raghavan reminds us that the mission comprised of an Orbiter, Lander and Rover. While ISRO may have lost communication with the Lander, the latter followed the planned descent trajectory from its orbit of 35 km to just below 2 km above the surface.
“Orbiter has already been placed in its intended orbit around the Moon and shall enrich our understanding of the moon’s evolution, map minerals, water molecules in the polar regions, using its eight state- of-the-art scientific instruments, “he said. The launch and mission management has also ensured a long life of almost 7 years for the orbiter instead of the planned one year, he added.
Chandrayaan-2 launch was earlier scheduled for (July.
He also said that the success criteria were defined for each and every phase of the mission and so far 90 to 95 percent of the mission objectives have been accomplished and will continue to contribute to Lunar science.
