A rocket carrying telecommunications equipment has launched into space.

An Atlas 5 rocket carrying the equipment lifted off at 4:12 p.m. Monday and was the heaviest payload ever launched aboard an Atlas 5 rocket.

The equipment will help with the operation of cell phones and other handheld devices and was built by Palo Alto, Calif.-based Space Systems/Loral.

The satellite is more than 27 feet tall and has a reflector that unfurls to more than 100 feet to supply solar power to the craft.

At launch, the fully fueled satellite weighed about 14,625 pounds.
