These side-by-side images of Mars, taken roughly two years apart, show very different views of the same hemisphere of Mars. Both were captured when Mars was near opposition, which occurs about every two years, when Earth’s orbit catches up to Mars’ orbit. At that time, the Sun, Earth and Mars fall in a straight line, with Mars and the Sun on “opposing” sides of Earth. The image on the left, taken on May 12, 2016, shows a clear atmosphere. The picture on the right, taken on July 18, 2018, features a global dust storm, with spring in the southern hemisphere. (NASA, ESA, and STScI)
