Space agency ISRO said India’s second lunar mission Chandrayaan-2 completed a year in orbit around the moon on Thursday and all the equipment is currently performing well and there is enough onboard fuel to keep it running.

Chandrayaan-2 was launched on July 22, 2019 and was put into lunar orbit exactly 20 years ago on 20 August. “Although the soft-landing attempt (of the lander carrying the rover) was not successful, the orbiter, equipped with eight scientific instruments, was successfully placed into lunar orbit.

The Indian Space Research Organization said that the orbiter completed more than 4,400 orbits around the moon and all the instruments are currently performing well. “The agency said in a statement that the spacecraft was healthy and the performance of the sub-systems was normal. The orbiter is being maintained.” 100 +/- 25 km in polar orbit with periodic orbit maintenance (OM) maneuvers. 17 OMs have been done so far since achieving 100 km lunar orbit on 24 September 2019. There is enough onboard fuel to last for about seven years, ”it added.

The Chandrayaan-2 mission was India’s first attempt to make a soft landing of a rover at the unchanged south pole of the lunar surface. However, Lander Vikram was working hard in September last year. Scientific payloads, including high-end cameras, climb the orbiter for mapping the lunar surface and study the moon’s exosphere (outer atmosphere).

The city headquartered ISRO said that the payload’s raw data has been downloaded during the year at the Indian Space Science Data Center (ISSDC). Public data was planned to be released by the end of this year, after validation by a formal peer review, it demonstrated the performance of the payload in orbit, combining first-year observations from Chandrayaan-2, strongly with lunar science Indicates its ability to contribute significantly. .

“The estimated long life of this orbiter could greatly contribute to the current resurgence of interest among the global scientific community for its continued presence on the moon,” the space agency said.

Chandrayaan-2 was launched to expand the knowledge about the Moon through detailed study of its topography, mineralogy, surface chemical composition, thermo-physical characteristics and atmosphere, giving a better understanding of the origin and evolution of the Moon. Was born. The first mission for the lunar Chandrayaan-1 launched in 2008, Indias provided clear evidence on the widespread presence of surface water and indications for subsurface polar water-ice deposits.
