Here’s this week’s image for the WITU Challenge, to test your visual knowledge of the cosmos. You know what to do: take a look at this image and see if you can determine where in the universe this image is from; give yourself extra points if you can name the spacecraft responsible for the image. We’ll provide the image today, but won’t reveal the answer until tomorrow. This gives you a chance to mull over the image and provide your answer/guess in the comment section. Please, no links or extensive explanations of what you think this is — give everyone the chance to guess.
UPDATE: The answer has now been posted below.
As Darth Vader once said, “All too easy.”
This is Mars moon Phobos, as seen by the Mars Reconnaissance Orbiter’s HiRISE Camera. And yes, the big impression is Stickney Crater. See more images of Phobos (and larger version), as well as more info from the HiRISE site here.
Right now, we don’t have a “hide” feature on comments. Sorry.
Check back next week for another WITU challenge.
