Parachute Descent: Like Viking, Pathfinder and the Mars Exploration Rovers, the Mars Science Laboratory was slowed by a large parachute. NASA Retires InSight Mars Lander Mission After Years of Science.A video still made available from Nasa TV shows the Perseverance Mars rover telemetry as it approaches. Guided Entry: The spacecraft was controlled by small rockets during descent through the Martian atmosphere, toward the surface. The rover appeared to have touched down about 32 metres (35 yards) from the nearest rocks.The entry, descent and landing sequence breaks down into four parts: In fact, the Curiosity Engineering Camera team, analyzing hazard avoidance camera (hazcam) images taken immediately after landing, noticed a shortlived. Where the Mars Exploration Rovers could have landed anywhere within their respective 150 by 20 kilometers (about 93 miles by 12 miles) landing ellipses, Mars Science Laboratory landed within a 20-kilometer (12-mile) ellipse! This high-precision delivery will open up more areas of Mars for exploration and potentially allow scientists to roam "virtually" where they have not been able to before. The new entry, descent and landing architecture, with its use of guided entry, allowed for more precision. It placed the rover on its wheels, ready to begin its mission at Gale Crater.Ĭuriosity Spotted on Parachute by Orbiter: NASA's Curiosity rover and its parachute were spotted by NASA's Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. Instead, the Mars Science Laboratory used the sky crane touchdown system, which is capable of delivering a much larger rover onto the surface. 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 of the familiar airbag landing of the past Mars missions, Mars Science Laboratory used a guided entry and a sky crane touchdown system to land the hyper-capable, massive rover. EDT on Aug 6, 2012).Įntry, descent, and landing for the Mars Science Laboratory mission included a combination of technologies inherited from past NASA Mars missions, as well as exciting new technologies. The entry, descent, and landing (EDL) phase began when the spacecraft reached the Martian atmosphere, about 125 kilometers (about 78 miles) above the surface, and ended with the rover safe and sound on the surface of Mars at 10:32 p.m.
