Sunset on Mars, as seen by the long-lived rover Opportunity. Otherworldly yet primal.
Notes about mars
NASA has launched (pardon the sorta pun) a new website for kids called Be a Martian, with various games that allow them to rack up points and earn badges as they learn about the red planet. The interesting twist? The games are actually crowdsourced work, real data sorting through the aligning of map images taken by Mars Odyssey explorer with elevation images from the Mars Global Surveyor project. Kids play a game, NASA gets useful data that’s otherwise hard to get computationally. The Register has a good writeup of the project.
