NASA's new virtual tours of the Space Station and new Mars Rover exactly approximate the sensation of not being in space

NASA's grabbed Microsoft's fancy Photosynth software once again to build virtual tours of the International Space Station and a full-scale model of NASA's Mars Science Laboratory rover. The interface lets you dive through endless, 3D-oriented photographs of the station's modules, both inside and out, and gives a really good impression of the size and complexity of the lab-on-wheels NASA is prepping for a 2011 mission to Mars. It's not like being there, but it's a good way to kill a lazy Saturday morning.
