About
Engineers at NASA's Jet Propulsion Laboratory performed tests on rocks such as this one to understand why the first attempt by the agency's Perseverance rover resulted in a powderized sample. A duplicate of the rover's drill attempted to create cores from crumbly rocks. 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 — NASA JPL · 2022. ABD devlet eseri: kamu mali, ticari islerde de serbestce kullanilabilir.
