摘要

描述	English: PIA19303: A Possible Landing Site for the 2020 Mission: Jezero Crater It's not only when trying to find a scientifically interesting place to land that the high-resolution images from HiRISE come in handy: it's also to identify potential hazards within a landing ellipse. This is one of the trickier aspects of selecting landing sites on Mars: a place to do good science but also where the risks of landing are low. Jezero Crater is an ancient crater where clay minerals have been detected, and with a delta deposit indicating that water was once flowing into a lake. Since clays form the in presence of water, this crater would be a very good candidate for a lander to explore and build on what we've learned from the Mars Science Laboratory. Could some form of ancient life have existed here and for how long? This image shows a possible landing site for the 2020 Mission: Jezero Crater, as seen by NASA's Mars Reconnaissance Orbiter. North-northwest is to the left. The location depicted is in the southeast quadrant of Jezero Crater.
