Chandrayaan-3 uncontrolled re-entry disaster

The Indian Space Research Organisation (ISRO) revealed that the cryogenic upper stage of the LVM3 M4 launch vehicle, responsible for placing the Chandrayaan-3 spacecraft into orbit on July 14 this year, underwent an uncontrolled re-entry into Earth’s atmosphere on Wednesday, ultimately crashing in the Pacific Ocean.

ISRO reported in a statement that the predicted impact point was over the North Pacific Ocean, with the final ground track not passing over India, according to PTI.

The rocket body, identified as part of the LVM-3 M4 launch vehicle, re-entered the Earth’s atmosphere at approximately 2:42 pm. This re-entry occurred within 124 days of its launch, and the post-mission orbital lifetime of the LVM3 M4 cryogenic upper stage adheres to the “25-year rule” for low-Earth orbit objects recommended by the Inter-Agency Space Debris Coordination Committee (IADC), as per ISRO.

After the Chandrayaan-3 injection, the upper stage underwent “passivation” to eliminate all residual propellant and energy sources, following space debris mitigation guidelines from the United Nations and IADC, ISRO stated.

“The passivation and post-mission disposal of this rocket body, following internationally accepted guidelines, once again reaffirms India’s commitment to preserving the long-term sustainability of outer space activities,” emphasized ISRO.
