The Skycrane let NASA's robotics engineers design a rover that could navigate the surface without worrying about having to make compromises just for its landing. The technique has also proven to pair nicely with radar sensors that let the spacecraft observe its surroundings and autonomously guide itself to a safe area.Feb 18, 2021

Why did perseverance use the sky crane?
The sheer size of the Mars Science Laboratory rover (nearly 900 kilograms, or almost 2,000 pounds) precluded it from taking advantage of an airbag-assisted landing. Instead, the Mars Science Laboratory used the sky crane touchdown system, which is capable of delivering a much larger rover onto the surface.
What happened to the NASA sky crane?
Just after the rover's wheels touched down, the sky crane flew off to crash-land intentionally a safe distance away — and Perseverance snapped a photo of the impact's immediate aftermath, NASA announced Wednesday (Feb. 24). "A moment of respect for the descent stage.
Why is NASA sending the rover?
The rover team now seeks to honor students who have demonstrated perseverance, sending them personal messages beamed by the rover from the Red Planet's Jezero Crater, which it has been exploring since landing in February 2021.
What happened to the crane that lowered Perseverance on Mars?
When the rover's sensors detect touchdown, it severs itself from the connecting cords and the decent stage flies off at least 492 feet from the landing target. However, the sky crane did not land on the surface, but intentionally crashed itself.
What is the sky crane maneuver?
When Curiosity's six wheels hit the red dirt inside Mars' huge Gale Crater, its "sky crane" descent stage will fly off and crash-land intentionally a safe distance away. NASA has dubbed the maneuver "seven minutes of terror."
Why was Perseverance sent to Mars?
The latest robotic explorer to land on Mars as part of NASA's ongoing Mars 2020 missions is a rover called Perseverance. The rover is designed to explore the Martian surface looking for signs of past and present life on the planet to contribute to NASA's Mars Exploration Programme's science goals.
How did Perseverance get to Mars?
How did Perseverance land on Mars? Perseverance followed an entry, descent, and landing (EDL) process similar to that used by NASA's Curiosity Mars rover when it landed in 2012. You can see an illustration of the process on the EDL section.
Did curiosity use a sky crane?
Instead of the familiar airbag landing systems of Mars Exploration Rover and Pathfinder, Curiosity will use a guided entry and a sky crane touchdown system to land the hyper-capable, massive rover. The sheer size of Curiosity (over 900 kilograms) would preclude it from taking advantage of an airbag-assisted landing.
How did the sky crane landing work?
The rockets slow the descent to 1 ½ mph and power a sideways parry to avoid the faster falling chute. As Sky Crane descends to 60 feet above Mars' surface, the rover inches down from underneath it on three nylon ropes like a spider spinning strands of its web.
