Year: 1 Mars year (1 revolution about the Sun) takes 687 Earth days.ĭay: 1 Mars day or sol (1 rotation) is 1.027 longer than an Earth day (24 hours, 39 minutes, 35 seconds).Ītmosphere: About 1% the density of Earth’s atmosphere at the surface. Orbit: Elliptical and about 1.5 times farther from the Sun than Earth is (about 141.5 million miles or 227.7 million kilometers from the Sun, on average). As a desert planet, Mars has about the same amount of surface area as the dry land on Earth.
Size: About half the diameter of Earth but twice the diameter of Earth’s Moon. Microphones: One on SuperCam to support instrument science and one on the port side of the rover for entry, descent, and landing, surface engineering, and public engagement. Two lithium-ion rechargeable batteries are available to meet power and energy demands during rover activities and are recharged by the MMRTG’s electrical output during quiescent periods. Department of Energy that uses the heat from the radioactive decay of plutonium-238 to generate a steady flow of about 110 watts of electricity.
Mars 2020 generator#
Power: Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) provided by the U.S. Sampling and caching system: One bit carousel with 9 drill bits for sample acquisition and surface abrasion, one 1.6-foot-long (0.5-meters-long) internal sample handling arm, and 43 sample collection tubes, including 5 “witness” tubes. Payload Instruments: 130 pounds (59 kilograms) for seven instruments: Mastcam-Z, Mars Environmental Dynamics Analyzer (MEDA), Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE), Planetary Instrument for X-ray Lithochemistry (PIXL), Radar Imager for Mars’ Subsurface Experiment (RIMFAX), Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC), and SuperCam. Weight: About 2,260 pounds (1,025 kilograms) on Earth, including the robotic arm with a 99-pound (45-kilogram) turret at the end, and about 866 pounds (393 kilograms) on Mars.ĭimensions: About 10 feet long (not including the arm), 9 feet wide, and 7 feet tall (about 3 meters long, 2.7 meters wide, and 2.2 meters tall) the robotic arm is about 7 feet (2.1 meters) long.
