This morning the Endeavour launched from the Florida coast on its final mission. The NASA shuttle will deliver to the International Space Station the largest physics experiment to blast into space, the Alpha Magnetic Spectrometer.
AMS-02 will allow scientists to study highly energetic subatomic particles outside Earth's atmosphere to search for signs of dark matter and primordial antimatter, or antimatter created during the big bang. Fifty-six institutions from 16 countries take part in the AMS-02 collaboration.
