Today, that is a nice picture of supernova remnant. Cool, but not really

Or click the right arrow under the picture for previous days.

Concerning soaring on Mars: Somewhere on the web site of X-Plane (a
flight sim), they explain very well the difficulties which you would
encounter when trying to fly on Mars.
