Brief
Across the north-eastern plains of the Sea of Tranquiility, more than 500 km from the Apollo 11 landing site, lie two magnificent near-parallel cracks in the Moon's surface, both more than 200 km long. Rupes and Rima Cauchy (the Cauchy scarp and rille) are named after the bright 12 km diameter impact crater Cauchy that lies between them. Both features were formed after the massive lava flows that formed the sea had cooled and had begun to settle, and they were caused by a localised stretching apart of the lunar crust. The images above do not show the features of the area very well and may be improved in the future as sources permit.
