Suppose NASA's Perseverance rover landed on Mars on February 18, 2021 as part of the Mars 2020 mission. The rover's main goal is to search for signs of ancient life and collect samples of rock and regolith (broken rock and soil) for possible return to Earth. Perseverance is also testing new technologies to help pave the way for future human exploration of Mars.
Can we infer that "NASA has never sent a rover to Mars."?
