Animation of Hohmann transfer – an elliptical orbit used to transfer a spacecraft between two circular orbits around the same body in the same plane. While this GIF shows the Hohmann transfer for NASA’s InSight spacecraft, Chandrayaan-2 shall be following a similar approach on August 14, 2019. From its orbit around the Earth, the spacecraft will enter an elliptical orbit that takes it nearer to the moon. Once there, a series of breaking mechanisms will slow it down for lunar capture.

With all of the five Earth-bound maneuvers successfully completed as planned, India’s Chandrayaan-2 will be shifting trajectories tomorrow (August 14, 2019). The Lunar Transfer Injection (LTI), scheduled between 0300 to 0400 hours (IST) will glide the spacecraft into a highly elliptical orbit precisely aimed to target the moon.
Chandrayaan-2 was launched by the Indian Space Research Organisation (ISRO) on July 22, 2019. The 8,488-pound (3850-kg) spacecraft was subjected to multiple orbit raising maneuvers that increased its altitude and decreased the influence of Earth’s gravity on the spacecraft. The fifth and final maneuver was performed on August 6, 2019. According to a statement from ISRO:
Fifth earth bound orbit raising maneuver for Chandrayaan-2 spacecraft has been performed ...
