Thermal stress would be a common cause considering Jezero has a ~60°C temperature swing from day to night. But IANAG™, so, let's wait and see that the geologists will have to say.
Meanwhile, I have a collection of other tagged #crackedRocks seen around Jezero Crater.
IANAG™ = I Am Not A Geologist 🙂
