Sky crane is a soft landing system used in the last part of the entry, descent and landing (EDL) sequence developed by NASA Jet Propulsion Laboratory for its two largest Mars rovers, Curiosity and Perseverance.
The sky crane system lowered the rover with a 7.6 m (25 ft) [137] tether to a soft landing—wheels down—on the surface of Mars. [ 139 ] [ 144 ] [ 145 ] This system consists of a bridle lowering the rover on three nylon tethers and an electrical cable carrying information and power between the descent stage and rover.
Steltzner is employed at NASA's Jet Propulsion Laboratory where he designed, tested and built the sky crane landing system for the Curiosity rover. [6] Steltzner was phase lead and development manager for EDL (Entry, Descent and Landing) of the lander, which successfully landed on Mars on August 5, 2012. [14]
Sky crane or skycrane may refer to: A type of aerial crane helicopter pioneered by Sikorsky in 1950s and 1960s where the fuselage is only large enough to accommodate the pilot and crew and does not have a cargo hold or passenger area.
If a rover is too heavy to use airbags, the retrorockets can be mounted on a sky crane. The sky crane drops from the parachute back shell and, as it nears the ground, the rover is lowered on a tether. When the rover touches ground, it cuts the tether so that the sky crane (with its rockets still firing) will crash well away from the rover. Both ...
