isro: Isro prevents Chandrayaan-2 collision with Nasa’s LRO | India Information

Almost a month after the precise manoeuvre, the Indian House Analysis Organisation (Isro) has disclosed that Chandrayaan-2 orbiter needed to carry out a collision avoidance manoeuvre (CAM) to keep away from colliding with NASA‘s Lunar Reconnaissance Orbiter (LRO), in October.
“A really shut conjunction between the Chandrayaan-2 Orbiter and the LRO of was anticipated to happen on October 20 close to the Lunar North pole. Over a span of 1 week previous to the conjunction, analyses by each Isro and JPL/NASA persistently confirmed that the radial separation between the spacecraft can be lower than 100 m and the closest strategy distance can be solely about 3 km on the aforementioned time of closest strategy,” an Isro assertion reads.
It added that each the businesses deemed that the scenario warranted a CAM to mitigate the shut strategy threat, and it was mutually agreed that Isro’s orbiter would bear the identical.
“The manoeuvre was scheduled on October 18, 2021. It was designed to make sure a sufficiently massive radial separation on the subsequent closest conjunction between the spacecraft. The CAM was executed nominally at 8.22pm (IST). After orbit willpower with post-manoeuvre monitoring knowledge, it was reconfirmed that there can be no additional shut conjunctions with LRO within the close to future with the achieved orbit,” Isro mentioned.
Chandrayaan-2 and LRO orbit Moon in an almost polar orbit and therefore, each the spacecraft come shut to one another over the Lunar poles.
“…It’s common for satellites in Earth Orbit to bear CAMs to mitigate collision threat because of area objects together with area particles and operational spacecraft. Isro screens such crucial shut approaches and execute CAMs for its operational satellites each time threat is assessed to be crucial. Nonetheless, that is the primary time such a critically shut conjunction was skilled for an area exploration mission of Isro,” the area company mentioned.
It added that the occasion highlights the significance of continuous evaluation of shut strategy conditions for lunar and martian missions, and the truth that efficient mitigation of shut strategy threat entails shut coordination and synergy amongst completely different area businesses.
