Few things you should know about Chandrayaan-3

The Indian Space Research Organisation (ISRO) will launch Chandrayaan-3, its third mission to the Moon, at 2.35 p.m. on Friday from Sriharikota in Andhra Pradesh. 

If the landing is successful, India will be part of the list, with the United States, Russia, and China as the fourth country to accomplish this extraordinary achievement.

Since Israel and India’s missions crashed-landed in 2019, and the spacecraft carrying a lander-rover from Japan and a rover from the UAE failed in 2022, the post of a successful soft landing has remained vacant.

Here are a few updates on Chandrayaan-3:

The journey from Earth to the Moon for the soon-to-be-launched spacecraft is projected to take about a month, with the landing scheduled for August 23.

After arrival, it will run for one lunar day, approximately 14 Earth days. One day on the Moon is equal to 14 days on Earth. The scientists hope to analyse lunar dirt, look into the moon’s surface using a rover, and record moon quakes.

The spacecraft will be launched on a heavy-lift vehicle called the GSLV Mark 3 (LVM 3). This strong three-stage medium-lift launch vehicle is the most durable in ISRO’s arsenal.

The LVM-3 weighs an incredible 640 tonnes at liftoff, standing at 43.5 metres in height and 4 metres in diameter. 

Its strength allows it to carry payloads weighing up to 8,000 kilogrammes into low-Earth orbit. It can carry around 4,000 kilogrammes of payload to more distant locations, such as geostationary transfer orbit.

The recently developed mission, according to ISRO, includes strong systems to assure a successful landing even if a component fails. 

Various eventualities, such as sensor collapse, engine failure, algorithmic flaws, and calculation errors, were examined, and adequate defences were developed.

ISRO lost communication with the lander during the Chandrayaan-2 mission when it was just a notch from the moon’s surface.
