Chandrayaan 3: Lunar evening nears ‘Shiv Shakti’ Point. What will occur subsequent?

Published: September 04, 2023

Chandrayaan-3, the world’s first mission to make a smooth touchdown close to the Moon’s south pole, is nearing its conclusion because the lunar evening approaches. The Indian Space Research Organisation (ISRO) has already declared that the ‘Pragyan’ rover has been “safely parked” after finishing its operations. The Vikram lander, which is transferring the information to the bottom, may also be positioned in sleep mode.

What will occur to Vikram lander, Pragyan rover?

Although the mission goal is full, ISRO scientists count on the gadgets to recharge, offered they will face up to the devices freezing chilly, which might plummet as little as -200 levels Celsius.

According to NASA’s Moon Tracker, the lunar sundown commenced on September 4, ranging from the situation the place Chandrayaan-3’s lander is located, which is called Shiv Shakti Point by India, and can lengthen till September 6. The subsequent lunar dawn is projected for September 20, in keeping with NASA’s tracker, however this may occasionally happen barely later on the south pole, anticipated on September 22.

“Hoping for a successful awakening for another set of assignments! Else, it will forever stay there as India’s lunar ambassador,” ISRO has stated.

What has Chandrayaan 3 mission achieved to this point?

Launched on July 14 because the fourth operational flight of the LVM3 rocket from the Satish Dhawan Space Station in Andhra Pradesh’s Sriharikota, India’s lunar mission efficiently landed on the lunar floor after a spaceflight of over a month on August 23, effectively inside the supposed touchdown web site. During its operational interval, it carried out a number of lunar experiments.

1) Before activating the Pragyan rover’s sleep mode, the ISRO reported that it had traversed over 100 metres. The rover can solely enterprise as much as 500 meters from the Vikram lander earlier than shedding communication.

2) The Laser-Induced Breakdown Spectroscope (LIBS) instrument onboard the rover definitively confirmed the presence of Sulphur (S) within the lunar floor close to the south pole, marking a historic in-situ measurement. Additionally, Al, Ca, Fe, Cr, Ti, Mn, Si, and O had been detected.

3) The Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere – Langmuir Probe (RAMBHA-LP) payload onboard Chandrayaan-3 Lander carried out groundbreaking measurements of the near-surface lunar plasma surroundings over the south polar area. Initial assessments point out that the plasma close to the lunar floor is comparatively sparse. These quantitative measurements maintain the potential to mitigate the interference that Lunar plasma introduces into radio wave communication and contribute to enhanced designs for future lunar missions.

4) The Instrument for the Lunar Seismic Activity (ILSA) payload on Chandrayaan 3 Lander, the primary Micro Electro Mechanical Systems (MEMS) technology-based instrument on the moon, recorded the actions of the Rover and different payloads. Additionally, it recorded an occasion on August 26, which ISRO stated, “appears to be of natural origin” and is presently below investigation.

5) The ChaSTE (Chandra’s Surface Thermophysical Experiment) instrument measured the temperature profile of the lunar topsoil across the pole to know the thermal behaviour of the moon’s floor. Equipped with a managed penetration mechanism able to reaching a depth of 10 cm beneath the floor and fitted with 10 particular person temperature sensors, the probe generated a temperature variation graph of the lunar floor/near-surface at varied depths throughout its penetration. This marked the primary such profile for the lunar south pole, and detailed observations are ongoing.

6) Another instrument onboard the rover confirmed the presence of Sulphur (S) within the area utilizing a unique method. The Alpha Particle X-ray Spectroscope (APXS) detected S, together with different minor parts. This discovery prompts scientists to develop new theories concerning the supply of Sulphur (S) within the space, similar to intrinsic, volcanic, meteoritic, and extra.
