After two and a half months of Chandrayan-2 mission, the Indian Space Research Organisation (ISRO) admitted that Vikram lander made a hard landing.
The details were revealed in a written answer to a question posed to the Department of Space in Lok sabha. Minister of State in the Prime Minister’s Office (PMO) Jitendra Singh said
” The indigenously developed Chandrayaan-2 spacecraft comprising of Orbiter, Lander, and Rover was successfully launched on-board indigenous GSLV MK III-M1 Mission on 22nd July 2019. After accomplishing four earthbound maneuvers and Trans Lunar Injection, the spacecraft was successfully inserted into the Lunar orbit on 20th August 2019. A series of moon-bound maneuvers were then carried out to achieve a Lunar orbit of 119×127 km. The Lander ‘Vikram’ was separated, as planned, from the Orbiter on 2nd September 2019. After two successful deorbiting maneuvers, powered descent of the Lander was initiated on 7th September 2019 to achieve a soft landing on the moon surface. The first phase of descent was performed nominally from an altitude of 30 km to 7.4 km above the moon surface. The velocity was reduced from 1683 m/s to 146 m/s. During the second phase of descent, the reduction in velocity was more than the designed value. Due to this deviation, the initial conditions at the start of the fine braking phase were beyond the designed parameters. As a result, Vikram hard landed within 500 m of the designated landing site.”
