Chandrayaan-3 Updates: Lander Module ready to be moved closer to moon

Chandrayaan-3 Updates: Lander Module successfully separates from Chandrayaan-3 and is prepared to be positioned closer to the Moon’s surface.

17 August, Bengaluru (PTI) The Chandrayaan-3 spacecraft’s Lander Module has successfully detached from the Propulsion module that has been launching it into space for the past few days, according to an announcement made by ISRO on Thursday.

Now that the lander (Vikram) and rover (Pragyan) are assembled in the Lander Module, they are prepared to be lowered into an orbit that will bring them closer to the Moon’s surface. On August 23, a soft landing is expected in the south pole of the moon. “Man, thanks for the ride! the Lander Module (LM) declared. LM and PM are successfully segregated from one another. After a deboost scheduled for tomorrow at 1600 IST, LM is expected to sink to a slightly lower orbit, according to ISRO’s tweet on X (previously Twitter).

After Thursday’s separation, the lander is anticipated to undergo a “deboost” (the process of slowing down) to place it in an orbit where the soft landing on the south pole of the Moon will be attempted and the Perilune (the orbit’s closest point to the Moon) and Apolune (the farthest point from the Moon) are both 30 kilometres.

Experts on Chandrayaan-3 Updates

According to the nation’s space agency, the Propulsion Module will continue its voyage for months or years in its current orbit.

“The SHAPE (Spectro-polarimetry of Habitable Planet Earth) payload onboard it (Propulsion Module) would perform spectroscopic study of Earth’s atmosphere and measure variations in polarisation from clouds on Earth – to accumulate signatures of Exoplanets that would qualify for our habitability!” According to ISRO, its U R Rao Satellite Centre in Bengaluru designed this payload.

Following its July 14 launch, Chandrayaan-3 updates, it entered the lunar orbit on August 5. Thereafter, orbit reduction manoeuvres were performed on the satellite on August 6, 9, 14, and 16 in preparation for today’s separation of both of its modules and the upcoming August 23 landing.

The ability to move the spacecraft from a horizontal to a vertical direction is the “trick we have to play” in this situation, according to ISRO Chairman S Somanath, who previously stated that the process of bringing the lander’s velocity from a height of 30 km to the final landing is the most crucial element of the landing.

Possibilities of the Safe Landing

“At the beginning of the landing procedure, the velocity is almost 1.68 km/s, but this speed is relative to the moon’s surface. The Chandrayaan-3 must become vertical because it is almost 90 degrees slanted in this location. So, mathematically speaking, the entire process of going from horizontal to vertical is quite interesting. We’ve run numerous simulations. The issue with Chandrayaan-2 occurred just here, according to Somanath.

Earlier, ISRO had launched the Chandrayaan-3 spacecraft into orbits that were farther and farther away from Earth through a total of five manoeuvres in the three weeks following the launch on July 14.

Then, on August 1, the spacecraft was successfully dispatched towards the Moon from Earth’s orbit in a crucial manoeuvre known as a slingshot move. The Chandrayaan-3 spacecraft left its orbit around the Earth after its trans-lunar injection and started travelling in a direction that would bring it close to the moon.

Chandrayaan-3 Goals

The lander will be tested, verified, and brought closer and closer to the moon. Then it will be given the necessary commands so that it takes off on schedule on August 23 to travel all the way to the intended place and have a safe and secure landing, according to Chandrayaan-I Project Director M Annadurai.

“This is just the beginning, and all future achievements must be carefully scrutinised. Since the launch vehicle and propulsion system have reached significant turning points, the match has officially begun. We are discussing the final overs here. It strikes me as a wonderful moment. The entire world is anticipating what Vikram and Pragyan will do when they finally come out. “I am eagerly anticipating as well,” Annadurai told PTI.

The goals of Chandrayaan-3’s mission are to show a soft and safe lunar surface landing, lunar rover wandering, and in-situ scientific experimentation.

The lander has the capacity to do a soft landing at a chosen location on the moon and deploy the rover, which will conduct in-situ chemical analysis of the Moon’s surface while it is moving.
