My brother sometimes threatens to run away and join the eventual one-way human mission to Mars. He can get a better idea of what would await him by checking out an interactive, panoramic view of the planet as seen by the Curiosity rover.
You can zoom and rotate the image to get a detailed, immersive view of the rocky surface, horizon, and the rover itself. It's the next best thing to being there, but without the crushing cold and lack of oxygen.
The impressive panorama is stitched together from images sent back by Curiosity. You can even count the pieces of debris scattered on the rover's top.
I recommend closing your curtains, turning off all the lights, queuing up David Bowie's "Life on Mars?," and turning on the full-screen mode.
