Watching the clouds drift by

Last week in my "what's up" roundup I noted that that in the previous week's Mars weather update the MARCI camera team on Mars Reconnaissance Orbiter had reported more water-ice clouds appearing in the equatorial regions of Mars, that is, in the skies of the rovers. It seems that the rover team noticed the news too, because Opportunity looked up to watch those clouds drift overhead:

When you next go outside, look up. Are there clouds in your sky? Do they move quickly or slowly? Are they puffy, white, and full of water, or do they look like the clouds over Opportunity -- wispy and dry with ice crystals? Spend a moment looking at your clouds, and wondering what it would be like to watch them from the surface of an alien world.
