The spacecraft that ferried India’s Chandrayaan-3 lander-rover duo to the moon has returned residence — type of.
In a surprise announcement on Monday (Dec. 4), the Indian Area Analysis Organisation (ISRO) stated it had moved Chandrayaan-3‘s propulsion module out of lunar orbit and positioned it excessive above Earth for a bonus mission, the place it now survives on leftover gas. The brand new experiment will show applied sciences that may assist Indian scientists convey samples from the moon to Earth sometime, ISRO stated.
The propulsion module, a box-shaped part of the Chandrayaan-3 spacecraft powered by photo voltaic panels, now circles Earth each two weeks. ISRO has not revealed what it plans to do with the spacecraft when it runs out of gas.

On Nov. 22, the module reached its closest level to Earth, coming inside 95,000 miles (154,000 kilometers) of the planet’s floor, ISRO officers stated. That was nonetheless excessive sufficient up, nonetheless, to be safely away from different satellites.
“As per present orbit prediction, there isn’t any risk of shut method with any operational Earth-orbiting satellites,” stated ISRO.
Earlier this 12 months, the propulsion module accomplished its primary activity when it positioned Chandrayaan-3’s robotic lander and rover in a decent orbit across the moon, previous to their historic touchdown close to the south pole in August. The module then moved to a barely larger orbit across the moon for a science experiment, learning our planet to help with the seek for Earth-like exoplanets.
By the tip of someday on the moon — a couple of month to us Earthlings — the module had 220 kilos (100 kilograms) of gas left after its major operations. By then, the first aims of the mission had been completed, so ISRO determined to convey it again to Earth, the area company stated within the Dec. 4 assertion.
In early October, the module was boosted from 93 miles (150 km) above the floor of the moon to slightly over 3,100 miles (5,000 km). To achieve the momentum required to return to Earth, it whirled across the moon 4 instances earlier than making its manner residence, stated ISRO.
Chandrayaan-3’s robotic explorers notched a number of enormous milestones and picked up beneficial science knowledge after touchdown in August at a spot that India calls Shiv Shakti Level. (The moniker is but to be accepted by the Worldwide Astronomical Union, the authority liable for assigning official names to celestial objects and their landmarks.)
In a primary, the six-wheeled, solar-powered rover Pragyan noticed sulfur in lunar soil, which reveals insights concerning the moon’s volcanic previous and will additionally assist area vacationers construct infrastructure on the moon. The lander Vikram made historical past of its personal when it used a thermometer-like probe to measure the temperature of the moon’s soil, the primary such in-situ measurement ever taken, scientists have stated.
The duo went silent in late September, lacking a wakeup name that coincided with the solar’s reappearance at their website on the finish of the lengthy, chilly lunar night time. However there is no disgrace in that; the 2 robots earned their (now apparently everlasting) relaxation.
“The mission aims of Chandrayaan-3 have been utterly met,” stated ISRO.
