Earth Photobombs Phobos In Incredible View From Mars


In an out-of-this-world first, Earth and Phobos have been photographed together in the sky by NASA’s Curiosity. The rover has previously snapped this moon and its companion Deimos, including in a beautiful eclipse, something also seen by Curiosity’s sibling Perseverance. The rover has also seen the Earth in the Martian sky, a bright dot like Venus is to us. But Phobos and Earth have never appeared together.

The stunning image was taken by the rover’s MastCam. It takes color images and videos of the terrain, but it has also been used to snap the sky above the Red Planet. The image was made of five short exposures and 12 longer ones on September 5. That was the 4,295th Martian day that Curiosity has spent on Mars.

Phobos is very unlike our own Moon. First of all, it is tiny. It’s just 22.2 kilometers (13.8 miles) across. To add to the list of peculiarities, it is also very close to Mars. Actually, Phobos is the closest orbiting moon in the Solar System. It goes around Mars in just seven hours at a distance of just 9,000 kilometers (5,600 miles). It is also shaped like a potato, it has one giant crater and a strange chain of craters across its surface, and – along with Deimos – may have been part of a larger moon or a chunk of the Red Planet itself.

It is believed that Phobos, or part of it, might in the future crash into Mars, so this picture shows a doomed moon and our precious pale blue dot.
