 The descent and soft-landing were to be performed by the on-board computers on "Vikram", with mission control unable to make corrections.The initial descent was considered within mission parameters, passing critical braking procedures as expected, but the lander's trajectory began to deviate at about above the surface.The final telemetry readings during ISRO's live-stream show that "Vikram" final vertical velocity was at above the surface, which a number of experts noted, would have been too fast for the lunar lander to make a successful landing.
