ISS ready for new zero-g experiments, students asked to float ideas

Those secret space experiments you've been scheming? They may never happen if you try to go it alone. Fortunately, the space science group NCESSE can get you a ride, having started the countdown for its fifth wave of microgravity experiments aboard the International Space Station. US and international students from grade 5 up to university level can submit ideas until September 12th, 2012, with final culling by December 7. The mini-labs -- which can include experiments in seed germination or crystal growth, for example -- are set to be ferried aboard a SpaceX flight in April 2013. Three similar missions have flown nearly 60 student experiments already, with a fourth set as soon as the Falcon 9 craft deigns to go. If you've got a flat-out good idea being prevented by big G, hit the source to see how you could get it fired off to the ISS.
