Contact Established Between Chandrayaan-2 Orbiter And Chandrayaan-3 Lander Module

ISRO on Monday said a two-way communication between the Chandrayaan-2 orbiter and Chandrayaan-3's lander module has been established.

"‘Welcome, buddy!' Ch-2 orbiter formally welcomed Ch-3 LM. Two-way communication between the two is established. MOX has now more routes to reach the LM," the national space agency said in a post on 'X'.


ISRO said on Sunday the lander module of Chandrayaan-3, the third lunar mission of India, is expected to touch down on the surface of the Moon around 6.04 pm on August 23.

The MOX (Mission Operations Complex) is located at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru. ISRO also said, in an update, that the live telecast of the landing event will begin at 5.20 pm on August 23.

The Chandrayaan-2 spacecraft comprising orbiter, lander and rover was launched in 2019. The lander with a rover in its belly crashed into the Moon's surface, failing in its mission to achieve a soft-landing.

ISRO said in 2019 that due to the precise launch and orbital manoeuvres, the mission life of the orbiter is increased to seven years.


The failure of Russia's Luna-25 moon mission will have no impact on ISRO's Chandrayaan-3 lunar venture, according to top Indian space scientists.

The Luna-25 spacecraft crashed into the Moon after it spun into an uncontrolled orbit, Russia's Roscosmos space agency said on August 20.

"It does not have any impact," K Sivan, who was heading ISRO when the Chandrayaan-2 mission was launched in 2019, told PTI on Monday when asked if ISRO would be under additional pressure ahead of the soft landing, following the Russian setback.


Chandrayaan-3 mission's lander module with a rover in its belly is expected to touch down on the surface of the Moon around 6.04 pm on Wednesday, ISRO had said on Sunday.

"It (Chandrayaan-3 mission) is going on as per plan. It (soft landing) will be done accordingly, Sivan said. "We are hoping that this time (unlike Chandrayaan-2) it (the touchdown) will be successful".

Former ISRO Chairman G Madhavan Nair dismissed talk in some quarters that India and Russia were engaged in a race to the Moon, and termed the crash-landing of Luna-25 as unfortunate.

"I know the (lander) module. It was ready way back in 2008. When I visited the lab (in Russia), they showed me the module. They didn't have the resources to fly (then), so it had been kept in cold storage for a long time. Now only they had resources (to launch)," he told PTI.

Ruling out any impact on the Chandrayaan-3 mission launched on July 14, Nair said India's venture is totally self-sufficient and "we are not dependent on them (Russia)". Right now, India's space cooperation with Russia is limited to training of Indian astronauts for the Gaganyaan human space flight mission.

"So, had it (Luna-25) landed, our data and their (Russian) data (collected based on experiments on the lunar surface) would have been complementary," he said.
