Rohit Bhartia of NASA's Mars 2020 mission holds a slice of a meteorite scientists have determined came from Mars. This slice will likely be used here on Earth for testing a laser instrument for NASA's Mars 2020 rover; a separate slice will go to Mars on the rover. Martian meteorites are believed to be the result of impacts to the Red Planet's surface, resulting in rock being blasted into the atmosphere. After traveling through space for eons, some of these rocks entered Earth's atmosphere. Scientists determine whether they are true Martian meteorites based on their rock and noble gas chemistry and mineralogy. The gases trapped in these meteorites bear the unique fingerprint of the Martian atmosphere, as recorded by NASA's Viking mission in 1976. The rock types also show clear signs of igneous processing not possible on smaller bodies, such as asteroids. https://photojournal.jpl.nasa.gov/catalog/PIA22245

The electricity needed to operate NASA's Mars 2020 rover is provided by a power system called a Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG. The MMRTG will be inserted into the aft end of the rover between the panels with gold tubing visible at the rear, which are called heat exchangers. Essentially a nuclear battery, an MMRTG uses the heat from the natural radioactive decay of plutonium-238 to generate about 110 watts of electricity at the start of a mission. Besides generating useful electrical power, the MMRTG produces heat. Some of this heat can be used to maintain the rover's systems at the proper operating temperatures in the frigid cold of space and on the surface of Mars. Some of it is rejected into space via the rover's Heat Rejection System. The gold-colored tubing on the heat exchangers form part of the cooling loops of that system. The tubes carry a fluid coolant called Trichlorofluoromethane (CFC-11) that helps dissipate the excess heat. The same tubes are used to pipe some of the heat back into the belly of the rover. MMRTGs are provided to NASA for civil space applications by the U.S. Department of Energy (DOE). The radioisotope fuel is inserted into the MMRTG at the DOE's Idaho National Laboratory before the MMRTG is shipped to the launch site. Electrically heated versions of the MMRTG are used at JPL to verify and practice integration of the power system with the rover. https://photojournal.jpl.nasa.gov/catalog/PIA23305

One investigation on NASA's Mars 2020 rover will extract oxygen from the Martian atmosphere. It is called MOXIE, for Mars Oxygen In-Situ Resource Utilization Experiment. In this image, MOXIE Principal Investigator Michael Hecht, of the Massachusetts Institute of Technology, Cambridge, is in the MOXIE development laboratory at NASA's Jet Propulsion Laboratory, Pasadena, California. Mars' atmosphere is mostly carbon dioxide. Demonstration of the capability for extracting oxygen from it, under Martian environmental conditions, will be a pioneering step toward how humans on Mars will use the Red Planet's natural resources. Oxygen can be used in the rocket http://photojournal.jpl.nasa.gov/catalog/PIA20761

The electricity for NASA's Mars 2020 rover is provided by a power system called a Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG. Essentially a nuclear battery, an MMRTG uses the heat from the natural radioactive decay of plutonium-238 to generate about 110 watts of electricity at the start of a mission. Besides generating electrical power, the MMRTG produces heat. Some of this heat can be used to maintain the rover's systems at the proper operating temperatures in the frigid cold of space and on the surface of Mars. This device, seen here before fueling and testing at the U.S. Department of Energy's Idaho National Laboratory, has "fins" that radiate excess heat. MMRTGs are provided to NASA for civil space applications by the U.S. Department of Energy (DOE). The radioisotope fuel is inserted into the MMRTG at the DOE's Idaho National Laboratory before the MMRTG is shipped to the launch site. Electrically heated versions of the MMRTG are used at JPL to verify and practice integration of the power system with the rover. https://photojournal.jpl.nasa.gov/catalog/PIA23306

NASA's 2020 Mars rover mission will go to a region of Mars thought to have offered favorable conditions long ago for microbial life, and the rover will search for signs of past life there. It will also collect and cache samples for potential return to Earth, for many types of laboratory analysis. As a pioneering step toward how humans on Mars will use the Red Planet's natural resources, the rover will extract oxygen from the Martian atmosphere. This 2016 image comes from computer-assisted-design work on the 2020 rover. The design leverages many successful features of NASA's Curiosity rover, which landed on Mars in 2012, but it adds new science instruments and a sampling system to carry out the new goals for the mission. http://photojournal.jpl.nasa.gov/catalog/PIA20759

An electrical cable can be seen snaking its way along insulation material in this image of the interior of the Mars 2020 spacecraft at it cruises through interplanetary space to the Red Planet. The cable and insulation are tied to the inside of the spacecraft's heat shield, which will protect the spacecraft from the extreme temperatures generated by friction as it enters the Martian atmosphere on Feb 18, 2021. The light source is the Sun, which likely entered through a vent hole in the Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) door. The picture was assembled from three images taken at different times by the Perseverance rover's rear left Hazcam during a systems check on Oct. 19, 2020. The colored pixels seen in the image are due to digital noise from the camera. https://photojournal.jpl.nasa.gov/catalog/PIA24233

This illustration of the Mars 2020 spacecraft (the solar-panel-covered cruise stage most visible here along with a portion of the white back shell) in interplanetary space was generated using imagery from NASA's Eyes on the Solar System. The image is from the mission's midway point between Earth and Mars — 146.3 million miles (235.4 million kilometers) away from each. In straight-line distance, Earth is 26.6 million miles (42.7 million kilometers) behind Perseverance, and Mars is 17.9 million miles (28.8 million kilometers) in front. Visible in the graphic are the solar panels on the cruise stage surrounding the top of the aeroshell. https://photojournal.jpl.nasa.gov/catalog/PIA24231

Mars 2020 engineers and technicians prepare the high-gain antenna for installation on the rover's equipment deck.
