Chandrayaan-2 Performs Manoeuvre To Avoid Collision With NASA Orbiter

Bengaluru:

India’s Chandrayaan-2 spacecraft carried out an evasive manoeuvre to keep away from collision with NASA’s Lunar Reconnaissance Orbiter (LRO), in response to Indian Area Analysis Organisation (ISRO).

A really shut conjunction between Chandrayaan-2 Orbiter (CH2O) and LRO of NASA was anticipated to happen on October 20 this 12 months at 05:45 UTC (11:15 am IST) close to the Lunar North pole, the Bengaluru-headquartered area company mentioned in an announcement.

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 2 spacecraft can be lower than 100 metres and the closest method distance can be solely about three km on the time of closest method.

Each the companies deemed that the scenario warranted a collision avoidance manoeuvre (CAM) to mitigate the shut method danger, and it was mutually agreed that CH2O would endure the CAM.

The manoeuvre was scheduled on October 18. It was designed to make sure a sufficiently massive radial separation on the subsequent closest conjunction between the 2 spacecraft.

The CAM was executed nominally at 14:52 UTC (8:22 pm IST), on October 18.

After orbit dedication of CH2O 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.

Like CH2O, LRO orbits the Moon in a virtually 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 endure CAM to mitigate collision danger on account of area objects together with area particles and operational spacecraft.

ISRO mentioned it usually screens such crucial shut approaches and execute CAMs for its operational satellites each time the collision danger is assessed to be crucial.

“Nevertheless, that is the primary time such a critically shut conjunction was skilled for an area exploration mission of ISRO which necessitated an evasive manoeuvre”, the assertion mentioned.

The occasion highlights the significance of continuous evaluation of shut method conditions for Lunar and Martian missions, and the truth that efficient mitigation of shut method danger entails shut coordination and synergy amongst completely different area companies, it was said.
