NASA has put off selecting the winners in a new competition for deals to resupply the International Space Station, prompting the agency to order two more commercial resupply missions from Orbital ATK to satisfy the orbiting lab’s cargo needs into early 2018, bringing the company’s total contract to 10 logistics flights.

An Orbital ATK Cygnus supply ship packed with 3.7 tons of cargo, supplies and experiments rode an Antares rocket into orbit from Virginia’s Eastern Shore on Sunday, setting course on a two-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).
