Photos: Delta 4’s foggy launch

An Atlas 5 rocket has been rolled out to its launch pad at Cape Canaveral for blastoff to deploy a replacement satellite to strengthen the Global Positioning System for U.S. military forces and the worldwide economy.

NASA simulated an in-flight launch abort of an Orion crew capsule high above Cape Canaveral on Tuesday, in a major test of the safety system that would whisk astronauts on future moon missions away from a failing rocket.

A SpaceX Falcon 9 rocket, flying with a first stage booster that was previously launched and recovered in May, lifted from Cape Canaveral at 1:18 a.m. EDT (0518 GMT) Tuesday with Indonesia’s Merah Putih communications satellite. The first stage accomplished a pinpoint landing on SpaceX’s drone ship in the Atlantic Ocean.
