Just north of the Martian equator lies a 45 km (28 mi) wide impact crater that scientists believe may have been the site of an ancient lake. Here at Jezero Crater, scientists theorize that its frozen soil may contain the most significant discovery of humankind, life. On February 18th, 2021, NASA's Perseverance rover will search this crater to find out if we're truly alone. What is the likelihood of life on Mars? How would the Mars landing be? What would these Martians look like? What if we found aliens on Mars? How will we send samples back to Earth?
