I spent over a year working with NASA on a variety of projects involving Photosynth. It was probably one of the highlights of my career to just be around the people who truly are at the cutting edge of human understanding of our place in the universe. I got to visit almost all the *known* installations, crawl around the space station mockup that they use to train astronauts and watch repairs in the Orbiter Processing Facility as they prepared for a mission. In effect a boyhood dream come true.
One of my favourite sites to visit each day is the NASA Astronomy Picture of the Day. It forces you to remind yourself how infinitesimally small we are in this strange universe we find ourselves within. I don't profess to understand everything they highlight each day but it's always inspiring to get a glimpse into their world.
