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.

Orbital ATK’s Antares rocket will deliver a Cygnus supply ship into orbit Monday to begin a three-day pursuit of the International Space Station.

A commercial supply ship owned and operated by Orbital ATK departed the International Space Station on Friday, heading for a destructive re-entry over the Pacific Ocean with more than 1.5 tons of trash. The station’s robotic arm released Cygnus at 1226 GMT (7:26 a.m. EST).
