Chandrayaan-3 mission: ISRO successfully performs fifth orbit-raising maneuver

The Indian Space Research Organization (ISRO) successfully completed the fifth and final orbit-ascent maneuver (Earth-bound perigee firing) of the Chandrayaan-3 mission on July 25.

The orbit-raising maneuver (Earth-bound perigee firing) was successfully carried out from the ISRO Telemetry, Tracking and Command Network (ISTRAC) at Bangalore.

The spacecraft is expected to reach an orbit of 127609 km x 236 km. This means that Chandrayaan-3 is now in an orbit, which is 236 km closest to Earth and 127609 km farthest.

“The orbit achieved will be confirmed after observation,” ISRO said after the successful orbit-raising maneuver.

Four previous orbit raising maneuvers were performed by ISTRAC between July 15 and July 20.

ISRO will perform Translunar Injection (TLI) on August 1 following the final orbit-raising strategy.

“The next firing, Translunar Injection (TLI), is planned for August 1, 2023, between 12 midnight and 1 am IST,” ISRO said.

Chandrayaan-3 consists of a lander module (LM), propulsion module (PM) and a rover which was launched on July 14 by LVM3-M4.

After the TLI takes place, the PM and LM will separate on August 17. A series of deboost maneuvers are also scheduled to take place before the power descent phase for a soft landing on the Moon. The lander is expected to touch down on the lunar surface at 5.47 pm on August 23
