Chandrayaan 2 fifth earth-bound orbit-raising manoeuvres successful

The fifth earth-bound orbit-raising manoeuvres of the Chandrayaan 2 spacecraft has been successfully completed Tuesday afternoon, as planned, the Indian Space Research Organisation confirmed in a tweet.


The manoeuvre was carried out at 3.04 pm IST using the onboard propulsion system for a firing duration of 1041 seconds (~17 minutes), four days after the fourth orbit-raising was completed, placing the spacecraft in a 276 x 142975 km orbit (nearest x furthest Earth-bound altitude), according to ISRO. The final orbit achieved by the Chandrayaan 2 spacecraft after the fourth orbit-raising is  277 x 89472 km.



ISRO also reported that all the spacecraft parameters were normal. The next step will be the Trans Lunar Insertion (TLI) that is scheduled for the afternoon of 14 August at 3.00 pm - 4.00 pm IST.

The TLI is a manoeuvre of thrusts used to set the spacecraft on the moon-bound path. After this, the Chandrayaan 2 composite will take less than a week to arrive in the proximity of the moon. This manoeuver will place the spacecraft on a 266 x 4,13,623 orbit that will end in the next stage of the mission: lunar transfer.
