Chandrayaan-3 Orbit Circularisation Phase Commences, India Getting Closer To The Moon

The third lunar mission from India, Chandrayaan-3, executed another significant manoeuvre on Monday between 11:30 and 12:30, according to the Indian Space Research Organisation (ISRO).

“The circularization phase of the orbit starts. Today’s precise manoeuvre resulted in a 150 km by 177 km orbit that is almost circular. The following operation is scheduled for August 16, 2023, at about 08:30 IST, according to a Monday post by the ISRO on X (previously Twitter).

Following the appropriate manoeuvres, a precise landing location close to the “Moon’s south pole” will be selected. The lander will then descend from orbit and try to make a soft landing when the propulsion module separates from it while it is in orbit.
