From left, actor Chris Evans, NASA's Perseverance Mars rover Surface Mission Manager Jessica Samuels, and NASA astronaut Tom Marshburn are seen in front of the rover model at the agency's Jet Propulsion Laboratory in Southern California on June 6, 2022. Evans visited JPL to learn more about space missions after starring as the lead voice in the space-themed movie "Lightyear." A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. https://photojournal.jpl.nasa.gov/catalog/PIA25312

Actor Chris Evans (left) receives a "boarding pass" to the Moon from Suzanne Dodd, director of the Interplanetary Network Directorate at NASA's Jet Propulsion Laboratory in Southern California. The pair are seen in the Space Flight Operations Facility at JPL on June 6, 2022. Evans visited JPL to learn more about space missions after starring as the lead voice in the space-themed movie "Lightyear." More than 3 million names, including Evans', were submitted online and will be included on a flash drive that will fly on the Orion spacecraft during NASA's Artemis I mission to the Moon. Artemis I will be the first uncrewed flight test of the Space Launch System rocket and the Orion spacecraft launching from NASA's Kennedy Space Center in Florida. NASA's Artemis program aims to establish a sustained human presence on the Moon that will serve as a launching pad for exploring Mars and beyond. https://photojournal.jpl.nasa.gov/catalog/PIA25311
