Video: CYGNSS launched by Pegasus rocket

Targeting a resumption of Antares cargo launches to the International Space Station as soon as July, Orbital ATK plans to roll out an upgraded Antares rocket to a launch pad in Virginia this week for a 30-second firing of the booster’s new engines.

NASA’s Dawn spacecraft will remain at Ceres for the rest of its mission, heading closer to the asteroid belt’s largest resident than ever before to obtain new measurements of ice, salts and a tenuous intermittent atmosphere detected around the dwarf planet, the space agency announced Thursday.

A 139-foot-tall Antares rocket is slated for a predawn launch Monday from the Mid-Atlantic Regional Spaceport on Virginia’s Eastern Shore, carrying a Cygnus supply ship heading for the International Space Station.
