ISRO’s Chandrayaan-3 On Course for the Moon
Pivotal Orbit Elevation Achieved for Chandrayaan-3
Taking another giant leap in its lunar exploration journey, ISRO successfully executed the fifth orbit-elevating operation, known as Earth-bound perigee firing, for the Chandrayaan-3 spacecraft. This operation, supervised from the ISRO Telemetry, Tracking and Command Network (ISTRAC), aims to position the spacecraft into an orbit ranging between 127609 km and 236 km. The national space agency stated that further observations will confirm the achieved orbit.

The Next Critical Step: TransLunar Injection (TLI)
ISRO has set the stage for the forthcoming essential procedure: the TransLunar Injection (TLI), scheduled for the early hours of August 1, 2023. This manoeuvre will see Chandrayaan-3 leaving Earth’s grasp, setting it on its trajectory towards the Moon, often referred to as the “lunar transfer trajectory”. This decisive step ensures that the spacecraft departs from Earth’s orbit and positions itself to be pulled into the Moon’s vicinity.
Chandrayaan-3’s Vital Mission and Historical Context
Post TLI, Chandrayaan-3 will embark on its lunar journey, heading towards its destined soft landing on the Moon slated for August 23. This mission carries immense significance for ISRO, especially following the challenges faced by its predecessor, Chandrayaan-2, in 2019. While the Chandrayaan-2 mission was not fully successful in its core objectives, Chandrayaan-3 seeks to make amends and further India’s aspirations in lunar exploration.
A Glimpse into the Future of Lunar Exploration
The director of ISRO, S Somanath, emphasized the importance of this mission, particularly the landing aspect. He said, “Chandrayaan-3 is a defining mission. Achieving a successful landing is pivotal. Without landing, there are no samples, no human landings, and no lunar bases. Thus, it’s a stepping stone for expansive lunar exploration.” A successful landing will indeed pave the way for ISRO to venture into more intricate lunar missions, possibly including moon bases and human expeditions. Such progress underscores India’s commitment and capabilities in space science, building on previous achievements and setting the stage for a brighter, spacefaring future.
