| A landing ellipse is 20km by 7km. Jezera is 49km in diameter. If we look at NASA's most recent landing - InSight - we can see a problem. InSight was meant to land at a longitude of 135.974°E, but it actually landed at 135.6234°E. Let's do some maths: | A landing ellipse is 20km by 7km. Jezera is 49km in diameter.
