But NASA's Dawn spacecraft has found evidence that smaller, water-rich asteroids once implanted themselves in Vesta's surface. The water stays locked up in hydrated minerals until subsequent impacts create enough heat to melt the rock and release the water as a gas, leaving pitted vents in the surface. The discovery shows that yet another body in the inner Solar System has a water cycle."
