The final impact velocity of approximately 298 km/h exhibited by this landslide had never before been recorded and thus might mark a world record; these speeds can be attributed mainly to a low friction coefficient (approximately 0.12) and a long run-out (approximately 2,500 m) along a gentle dip-slope surface (approximately 15°).
A complex sequence of mechanical operations was scheduled to follow--separation from a cruise ring that had supported the spacecraft, a fiery entry behind its heat shield, parachute deployment, jettisoning of the heat shield, radar locking onto the surface, separation from the parachute, and a rocket-powered deceleration to a gentle touchdown on the surface.
