About the Cygnus CRS-2 NG-15 (S.S. Katherine Johnson) Mission
| Type | Resupply |
|---|---|
| Orbit | Low Earth Orbit |
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.
Launch Pad & Location
Launch Area 0 A
Wallops Flight Facility, Virginia, USA
| Launches | 19 |
|---|---|
| Orbital Launch Attempts | 19 |
| Total Launches | 87 |
Wallops Flight Facility is a rocket launch site on Wallops Island on the Eastern Shore of Virginia, United States, just east of the Delmarva Peninsula and north-northeast of Norfolk. The facility is operated by the Goddard Space Flight Center in Greenbelt, Maryland, and primarily serves to support science and exploration missions for NASA and other federal agencies. WFF includes an extensively instrumented range to support launches of more than a dozen types of sounding rockets; small expendable suborbital and orbital rockets; high-altitude balloon flights carrying scientific instruments for atmospheric and astronomical research; and, using its Research Airport, flight tests of aeronautical research aircraft, including uncrewed aerial vehicles.
Northrop Grumman Antares 230+ Rocket
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.

Mission Spacecraft
Cygnus CRS NG-15 (S.S. Katherine Johnson)
Cygnus CRS NG-15 (S.S. Katherine Johnson) was the spacecraft used for this mission. It is a Northrop Grumman Cargo Resupply designed for Cargo Earth Orbit Logistics and traveled to International Space Station.
This is the fifteenth flight to the ISS by the Cygnus spacecraft under the CRS program and their fourth under the CRS-2 program. This is also the 11th use of the enhanced size Cygnus. The Cygnus spacecraft is launched aboard Antares, Atlas V, or Falcon 9 to deliver cargo to the ISS under NASAs CRS contracts. It has no heatshield so at the end of its mission its used to dispose of waste by burning up in the Earths atmosphere. 1 week to 2 years design life.
