NASA’s Lunar Reconnaissance Orbiter (LRO) lately bounced a laser off India’s Vikram moon lander, marking a space-communications first.
Vikram touched down close to the lunar south pole on Aug. 23, 2023 on India’s pioneering Chandrayaan-3 mission, which additionally included a rover named Pragyan. Vikram carried on its physique the tiny NASA Laser Retroreflector Array, or LRA for brief.

Bounce again
The laser gentle present between LRO and Vikram passed off on Dec. 12, 2023, with the orbiter transmitting laser pulses towards the lander after which registering the sunshine that bounced again.
Vikram was some 62 miles (100 kilometers) from LRO on the time, silently sitting close to Manzinus crater within the moon’s south pole area. (Vikram and Pragyan aced their floor missions, then went silent about two weeks after landing, as anticipated.)
“We have confirmed that we will find our retroreflector on the floor from the moon’s orbit,” mentioned Xiaoli Solar, who led the group at NASA’s Goddard Area Flight Heart in Greenbelt, Maryland, that developed the retroreflector positioned on Vikram as a part of a partnership between NASA and the Indian Area Analysis Organisation (ISRO).
“The subsequent step is to enhance the approach in order that it might probably turn out to be routine for missions that need to use these retroreflectors sooner or later,” Solar mentioned in a NASA statement.
Extra to return
A number of NASA retroreflectors are slated to fly aboard private and non-private moon landers — together with one machine carried by Astrobotic’s troubled Peregrine spacecraft, which is ready to reenter Earth’s ambiance on Jan. 18 as a result of a propulsion mishap.
One other Laser Retroreflector Array is onboard Japan’s SLIM lander, as a result of land on the moon on Jan. 19.
Additionally, an LRA is onboard Intuitive Machines’ Nova-C lunar lander, which is ready to launch atop a SpaceX Falcon 9 rocket in mid-February. Intuitive Machines will carry six NASA payloads, together with the retroreflector, below NASA’s Industrial Lunar Payload Providers initiative.
