Vikram Lander Is Set Into Sleep Mode: ISRO

By LokMarg

In a major development, the Indian Space Research Organization (ISRO) announced that the ‘Vikram Lander’ has been set into sleep mode at around 08 AM (Indian Standard Time) on Monday morning.

ISRO said that the data collected by the payloads is received at the Earth and the Payloads are now switched off. It is expected by ISRO that Vikram Lander and Pragyaan will awake again on around September 22.

“Vikram Lander is set into sleep mode around 08:00 Hrs. IST today. Prior to that, in-situ experiments by ChaSTE, RAMBHA-LP and ILSA payloads are performed at the new location. The data collected is received at the Earth. Payloads are now switched off. Lander receivers are kept ON. Vikram will fall asleep next to Pragyan once the solar power is depleted and the battery is drained. Hoping for their awakening, around September 22, 2023,” ISRO posted on X.

The Vikram lander was carrying the Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure surface thermal properties, the Instrument for Lunar Seismic Activity (ILSA) to measure seismicity around the landing site, the Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) to study the gas and plasma environment, and a passive laser retroreflector array provided by NASA for lunar ranging studies.

On August 23, India took a giant leap as the Chandrayaan-3 lander module successfully landed on the moon’s South Pole, making it the first country to have achieved the historic feat and bringing to an end the disappointment over the crash landing of the Chandrayaan-2, four years ago. Overall, India became the fourth country – after the US, China, and Russia – to have successfully landed on the moon’s surface.

After having landed, the Vikram Lander and the Pragyan rover performed different set tasks on the lunar surface, including finding the presence of sulphur and recording relative temperature. Upon landing, the lander and the rover were to operate for one lunar day. One day on the Moon is equal to 14 days on Earth. (ANI)

Launch Of Chandrayaan-3 Mission

ISRO Completes ‘Launch Rehearsal’ Of Chandrayaan-3

By LokMarg

The Indian Space Research Organisation (ISRO) on Tuesday completed the ‘launch rehearsal’ for Chandrayaan-3 which will be launched on July 14 from Satish Dhawan Space Centre, Sriharikota.

“Chandrayaan-3 mission: The ‘Launch Rehearsal’ simulating the entire launch preparation and process lasting 24 hours has been concluded,” ISRO tweeted.

The Indian Space Research Organisation (ISRO) on July 5 integrated the encapsulated assembly containing Chandrayaan-3 with the launch vehicle– LVM3 at Satish Dhawan Space Centre here.

“Today, at Satish Dhawan Space Centre, Sriharikota, the encapsulated assembly containing Chandrayaan-3 is mated with LVM3,” tweeted ISRO.

The space agency’s chairman S Somnath last month told ANI that they are planning for the launch day of its third lunar mission between July 13-19.

“We will be able to do a soft landing on the moon. The launch day is July 13, it can go upto 19th,” Somnath had said.

Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface.

Earlier in October last year, the ISRO chairman said that it is likely to launch its Chandrayan-3 mission in June 2023.

Chandrayaan-2, India’s second mission to the moon, was launched on July 22, 2019, from Satish Dhawan Space Center, Sriharikota. But the mission failed after the Vikram lunar lander crashed on the Moon during the early hours of September 6. (ANI)
