On June 4, 2010, the first Falcon 9 rocket built by SpaceX blasted off from Cape Canaveral on its maiden voyage and reached orbit. The first stage is back on the launch pad Sunday for its second flight.
The launch was originally scheduled for early Wednesday morning, and then postponed again to early Friday.

The launch from Cape Canaveral Air Force Station's Launch Complex 40 carried a satellite for one world's biggest satellite companies - Luxembourg-based SES.
The satellite will provide direct-to-home TV, broadband and data relay services to customers across the Asia-Pacific region, Australia and the Middle East, according to CBS News.
The National Weather Service had predicted decent weather for the launch with only a 20 percent chance of rain, with gusts as high as 18 to 20 miles per hour and sky cover of about 50 percent in the Titusville area.More news: 7 dead after Guatemala's Fuego volcano erupts
