Chandrayaan-2's Vikram lander hard-landed as a reduction in velocity during its descent did not match with the designed parameters, the government said on Wednesday throwing more light on ISRO's dashed hopes of making a soft landing on the lunar surface in its maiden attempt.

In a written reply to a question in the Lok Sabha, Jitendra Singh, the minister of state in the Prime Minister's Office, who looks after the department of space, said the first phase of descent was performed nominally from an altitude of 30 kms to 7.4 kms above the moon's surface and velocity was reduced from 1,683 metres per second to 146 metres per second.
