CAPE CANAVERAL, Fla. — An unmanned, privately owned Falcon 9 rocket and Dragon cargo capsule blasted off from Cape Canaveral on Sunday on a mission to restore a US supply line to the International Space Station after the retirement of the space shuttle. Powered by nine oxygen and kerosene-burning engines, the 157-foot (48-meter) tall rocket, built by Space Exploration Technologies, lifted off from its seaside launch pad at Cape Canaveral Air Force Station at 8:35 P.M. EDT (0035 GMT Monday). “This was a critical event for NASA and the nation tonight,” said NASA Administrator Charles Bolden. “Just over a year after the retirement of the space shuttle, we have returned space station cargo-resupply missions to US soil.” The Falcon booster, flying for the fourth time, streaked through balmy, partly cloudy skies as it headed east over the Atlantic Ocean toward the station's orbit, some 250 miles (400 km) above Earth. — Reuters
