Fact unknow
Both photos of Mars are from 2001, with about a month of interval between them. At first is how Mars usually is. The second picture shows how Mars gets during its global sandstorms. The last of these storms was in 2007, but we had few instruments studying the planet. With the data collected scientists have noted an increase of water vapor up to 100 times in the Martian atmosphere. This may explain the loss of water and hydrogen from the red planet. Now in 2018 will start a storm that will extend until 2019, and as we have more equipment, we can study the phenomenon more deeply.

Do you what the rovers would experience during a global sandstorm? Would it affect their operation at all?
