United Launch Alliance technicians positioned the first stage for the next Atlas 5 rocket on a mobile launch platform Friday at Cape Canaveral, a key step in preparations for an October mission that will debut a new solid-fueled booster design.

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.

An Ariane 5 rocket launched Tuesday at 2101 GMT (4:01 p.m. EST) from French Guiana with a communications satellite to provide broadband and television services for the government of Saudi Arabia and commercial clients across Europe and the Middle East, and an Indian payload to help bridge the digital divide in South Asia.
