Perseverance also used the same entry, descent and landing (EDL) strategy as Curiosity. "These will gather science data in ways that weren't possible before." Perseverance's seven instruments "build on the success of MSL, which was a proving ground for new technology," said George Tahu, NASA's Perseverance program executive. Curiosity's main task involves assessing the habitability of ancient Mars, whereas Perseverance will hunt for evidence of ancient Martians. But those instruments are quite different than the gear aboard Curiosity because the two rovers have divergent goals. Like Curiosity, Perseverance has a rectangular body, six wheels, a robotic arm, a drill for sampling rocks, cameras and scientific instruments. (1,025 kilograms), Perseverance weighs less than a compact car. Perseverance is about 10 feet long (not including its robotic arm), 9 feet wide, and 7 feet tall (about 3 meters long, 2.7 meters wide and 2.2 meters tall). Roughly 85% of Perseverance's mass is based on Curiosity's "heritage hardware," saving NASA time and money and reducing risk considerably, agency officials have said. Like Curiosity, the Perseverance rover was built by engineers and scientists at NASA's Jet Propulsion Laboratory in Pasadena, California. If Perseverance looks familiar, that's because the robotic explorer is largely based on its predecessor, the Mars Science Laboratory (MSL) Curiosity rover, which landed in August 2012 and is still going strong today.
