A Northrop Grumman Antares rocket blasted off from Virgina's Eastern Shore on Tuesday, climbed away over the Atlantic Ocean and set off after the International Space Station to deliver 4 tons of crew supplies, equipment and research material.
The rocket's two Russian-built RD-181 first stage engines ignited with a rush of flame at 6:01 p.m. EDT, pushing the 139-foot-tall Antares away from pad 0A at the Mid-Atlantic Regional Spaceport — MARS — at NASA's Wallops Island flight test facility.
