Environmental Plot at Jezero
This graphic depicts the environmental conditions at Jezero Crater from the day NASA's Perseverance Mars rover landed there – on Feb. 18, 2021, the first Martian day, or sol, of the mission – through Sol 600.
The black line indicates a climatological model of atmospheric opaqueness (a measurement known as "tau") over a Martian year. The expected daily insolation, or the amount of Sun's rays reaching the solar panel, is illustrated by the green dotted line. While a year on Earth lasts 365 days, on Mars a year lasts 668 sols.
The Ingenuity Mars Helicopter was built by JPL, which also manages the technology demonstration project for NASA Headquarters. It is supported by NASA's Science, Aeronautics Research, and Space Technology mission directorates. NASA's Ames Research Center in California's Silicon Valley, and NASA's Langley Research Center in Hampton, Virginia, provided significant flight performance analysis and technical assistance during Ingenuity's development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance and major vehicle components. Lockheed Martin Space designed and manufactured the Mars Helicopter Delivery System.
