SUMMARY: The European Space Agency's Mars Express has taken an new photograph of Nicholson Crater, located at the southern edge of Amazonis Planitia on Mars. This crater is 100 km (62 km) across and has a very large raised central mount. Large craters often have this kind of central peak, which forms when material rebounds after a meteor impact, but Nicholson Crater's peak is heavily eroded by wind and water.

One often sees ths effect with a drop of milk. When one body hits another, there's a little "dip" in the middle. It's the rebound effect caused by inertia (the bigger body repulses the smaller body with little change to momentum on the larger body's part). Hence there's a bit of "bounce" causing this effect. Mars is usually the winner in the momentum game. Just like Earth. ;)

Hi James, and welcome to the forum....

Just one pointer, religious fanfare is banned on all UT forums. So please refrain from putting this at the bottom of all your posts. thanks.
