SpaceX's recycled Dragon spacecraft reaches space station Shortly after the Dragon departed the International Space Station late Sunday night, astronaut Jack Fischer praised the craft through radio communications with NASA mission control in Houston. "I could even say it was slathered in awesome sauce. This baby has had almost no problems, which is an incredible feat considering it's the first reuse of a Dragon vehicle," Fischer said. "And the science we've done -- oh my, the science. Most of the 6,000 pounds of cargo carried was science, and almost all the return cargo are precious samples for discoveries we can't wait to see." Those samples include tissue from rodents sent to the ISS for a number of experiments. One of these experiments will gauge the effectiveness of a drug that could be used to treat osteoporosis.
