Gallery: Antares rocket explodes

United Launch Alliance has granted “flight clearance” for its workhorse Atlas 5 rocket to resume satellite deployments after linking an errant valve with the fuel usage crunch on its most recent mission and tweaking subsequent vehicles.

Officials scrubbed the launch of an Antares rocket with fresh supplies for the International Space Station after a boat sailed into restricted waters off Virginia’s Eastern Shore, violating safety rules for a widely-anticipated launch that was expected to be visible to millions along the U.S. East Coast.
