After a 24-hour delay, the launch of the satellite that will test elements of Einstein's Theory of Relativity was a success.  The Gravity Probe B (GP-B) blasted off an oceanside pad at Vandenberg AFB aboard a Delta II rocket.  The satellite separated from the rocket 75 minutes later and that marked the start of an 18-month mission to validate Einstein's predictions about space and time.  The GP-B experiment will have two months of preparation before calculating data for 16 months.  More images from the launch are available from:
