Atlas V Rocket Prepared for Orbital ATK CRS-4

After yesterday’s postponement due to unfavorable weather, the countdown is underway for the liftoff of a United Launch Alliance Atlas V rocket at Cape Canaveral Air Force Station’s Space Launch Complex 41. A commercial resupply services mission to the International Space Station, an enhanced Orbital ATK Cygnus spacecraft will deliver more than 7,000 pounds of supplies, equipment and scientific research materials that improve life on Earth and drive progress toward future space exploration.
