Do you pay any attention to space shuttle launches?

"The space shuttle Endeavor is set to launch this evening with an odd assortment of cargo—including live spiders, butterflies, and new technology to turn urine into drinking water," reports National Geographic.  "Besides seven astronauts, Endeavor's cargo includes two new sleeping chambers, a second toilet, and a water-purification system, all of which will let NASA double the occupancy of the International Space Station to six. The new mission is the 124th space shuttle flight and the 27th to the International Space Station. The seven-member crew will spend 15 days performing basic maintenance on the station before returning to Earth."
