India once dreamed of becoming the fourth country to go to the moon. Its Moonship 2 orbiter runs smoothly until the spacecraft sends the lander to the moon’s surface. If all goes according to plan, the rover will roam the unexplored moon’s south pole.
But the lander then lost contact shortly after the orbiter split. At the time, the Indian Space Research Organization (ISRO) did not provide much detail. The Israeli Space Research Organization said it had simply lost contact with the lander and indicated that the data was being analysed. The Government of India has now issued a brief report explaining the problems.
According to the report, the cause of the lander’s loss was simple, with the lander’s brake thruster malfunctioning and causing the lander to crash. In the second stage of the decline, the speed decreases beyond the design value. As a result of this deviation, the initial conditions at the beginning of the fine braking phase exceed the design parameters. The result is a hard landing of the lander, with the actual landing site within 500 meters of the specified landing site.
The Indian Space Agency did not provide the exact cause of the failure of the landing system, but said the Chandrayaan-2 spacecraft, which collected information in orbit around the moon, was successful. All eight of the most advanced scientific instruments on the orbiter are designed to operate, the agency said.
