Close-up color image of Phobos, Mars' doomed moon, captured by the Mars Express spacecraft. The image reveals Phobos' cratered surface and the grooves indicating the intense gravitational forces pulling it towards Mars. The scale bar indicates a distance of 5 kilometers. In about 100 million years, Phobos will likely crash into Mars or break apart, forming a ring around the planet.
