Both Arrays Deployed as Mission Begins

Both of the solar arrays on the Orbital ATK CRS-7 Cygnus module have successfully deployed and are beginning to draw power, reports Frank DeMauro, vice president and general manager of Orbital ATK’s Advanced Programs Division, Space Systems Group.

For the next couple of hours, DeMauro said, the spacecraft will undergo a detailed checkout before starting the first of several orbit-raising burns it will perform in the coming days as it pursues a Saturday-morning rendezvous with the International Space Station.

A post-launch news conference is planned for 2:30 p.m. EDT on NASA Television.
