Throw back to STS-134, the second-to-last mission of NASA's Space Shuttle program and the 25th and last spaceflight of Space Shuttle Endeavour where Mark Kelly (identical twin brother of retired astronaut Scott Kelly) served as the mission commander. Among many interesting research projects and supplies, Endeavour brought 13 Lego kits to the ISS, where astronauts built Lego models to see how they would react in microgravity, as part of the Lego Bricks in Space program. The results were shared with schools as part of an educational project. Pictured here is actor Seth Green waiting to join tens of thousands of people in watching the launch.
