NASA’s Swift satellite is due to arrive at Florida’s Cape Canaveral today, to prepare for its launch in October. Named after the fast-moving bird, Swift will track down the fastest and most powerful known explosions in the Universe: gamma ray bursts. Swift has one instrument to detect bursts in the sky, and then it can swing around two high-resolution telescopes in less than a minute for a closer look. It’ll also inform the astronomical community of a blast so that anyone watching the sky can tune in as well and watch the explosion unfold. Swift should help turn up more than 100 bursts a year.
