Overview

Destination: Low Earth Orbit
Mission: Resupply

Low Earth Orbit Launch Area 0 A Wallops Island, Virginia, USA Probability: 75%

This is the 15th planned flight of the Orbital ATK's uncrewed resupply spacecraft Cygnus and its 14th flight to the International Space Station under the Commercial Resupply Services contract with NASA. This Cygnus spacecraft carries the name of American mathematician Katherine Johnson, whose calculations of orbital mechanics as a NASA employee were critical to the success of the first and subsequent U.S. crewed spaceflights.

Antares 230+

Family:
Configuration: 230+

Antares known during early development as Taurus II, is an expendable launch system developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation Systems after Northrop Grumman acquired Orbital ATK) and the Yuzhnoye Design Bureau to launch the Cygnus spacecraft to the International Space Station as part of NASA's COTS and CRS programs. Able to launch payloads heavier than 5,000 kg (11,000 lb) into low-Earth orbit, Antares is the largest rocket operated by Orbital ATK. Antares launches from the Mid-Atlantic Regional Spaceport and made its inaugural flight on April 21, 2013.
