Analyzing rover data is one way we learn about Mars’ geologic past, but planetary geologists can also study “terrestrial analogs.” These are locations on Earth where we can make valuable comparisons to what we see on other planetary bodies, such as Mars, to help us understand their landscapes. I’ve enjoyed hearing comparisons between Jezero and Earth from members of our Science Team; most recently we discussed how the Jezero delta sediments might be similar to those in Greece. As a British-Greek member of the team, I used to drive through the Gulf of Corinth each summer to visit family in Ακράτα (Akrata). Little did I know that I was gazing out the window at a wonderful analog for some of the deltaic features we’re seeing in Jezero today!
Over the next few months, we’ll use the entire suite of Perseverance instruments to explore the delta. We expect to find rocks that will be rather different from the igneous rocks (meaning they formed from magma or lava) of the crater floor. During that exploration, we will also take samples of some of the most interesting and astrobiologically promising rocks. I can’t wait to see what Perseverance will find!
