Mars Transit

4 August 2014

About a year ago Curiosity happened to be in the path of an eclipse. So Curiosity was directed to take a series of photographs of the Sun. You can see the result here. The shadow moving across the Sun is Phobos, and you can see it pass in real time. Phobos is must smaller than our Moon, only about 27 km across. It is also much closer to Mars than the Moon is to Earth. Phobos doesn’t completely block out the Sun, but it does block a good chunk of it.

But perhaps most amazing is that we’re now observing solar eclipses on other planets.
