ISRO successfully completed the fifth and final orbit-raising manoeuvre of the Chandrayaan-3 mission. The spacecraft is expected to attain an orbit of 127609 km x 236 km. The TransLunar Injection is planned for Aug 1, 2023, between 12 midnight and 1 am IST.
The Indian Space Research Organisation (ISRO) on July 25 successfully completed the fifth and final orbit-raising manoeuvre (Earth-bound perigee firing) of the Chandrayaan-3 mission.
The orbit-raising manoeuvre (Earth-bound perigee firing) was performed successfully from ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru.
The spacecraft is expected to attain an orbit of 127609 km x 236 km. This means that Chandrayaan-3 is now in an orbit, which when closest to earth is at 236 km and farthest at 127609 km.
“The achieved orbit will be confirmed after the observations,” ISRO said after the successful orbit-raising manoeuvre.
The four earlier orbit raising manoeuvres were performed by ISTRAC between July 15 and July 20.
Following the final orbit-raising manoeuvre ISRO will perform the TransLunar Injection (TLI) on August 1.
“The next firing, the TransLunar Injection (TLI), is planned for August 1, 2023, between 12 midnight and 1 am IST,” ISRO said.
