Orbital ATK readied an upgraded Antares rocket for launch Monday from Wallops Island, Va., to deliver more than 3 tons of crew supplies, science gear, spare parts and three small satellites to the International Space Station to test miniaturized, low-cost technologies for Earth observation applications.

An Antares rocket is being prepared for launch for the first time in two years after emerging from the Horizontal Integration Facility at Wallops Island, Virginia, on Thursday evening for a one-mile trip to the launch pad.

The spacecraft will journey back to Earth without the two astronauts it launched with back on June 5. Undocking is set for 6:04 p.m. EDT (2204 UTC) with landing just after midnight on Saturday.
