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.
