“Sunday night”, at around 2:00 am EST (and I myself am still confused as to whether they mean Sunday morning or Monday morning) a space vessel will ram into a comet. And now, it seems, the event will be televised…sorta. 🙂
UPDATE: Ok, this is taking place Sunday night/Monday morning:
NASA’s Deep Impact spacecraft continues to sail through its final checkout, as it hurtles toward comet Tempel 1. Impact with the comet is scheduled for 1:52 a.m. EDT, July 4 (10:52 p.m. PDT, July 3).
