When he's not busy with his full-time gig, NASA Astronaut Don Pettit takes the time to run some of his own personal science experiments. His latest? A zero-gravity didgeridoo performance — for science.
The International Space Station is in constant motion, whipping around the Earth at some 17,000 miles per hour. But according to current ISS inhabitant and NASA astronaut Don Pettit, there’s no reason why a bullet-fast orbital space station with no fixed location shouldn’t have a fixed mailing address--after all, Navy ships have mailing addresses, as do remote outposts like McMurdo Station in Antarctica--and he’s devised just such a postal nomenclature to satisfy this need via his NASA blog.
