CRS Orbital 4

Dimensions approx.(4.25") 105 mm dia.

CRS OA-4, also known as Orbital Sciences CRS Flight 4 was the fourth successful flight of the Orbital ATK un-crewed re-supply spacecraft Cygnus and its third flight to the ISS under the Commercial Re-supply Services contract with NASA. With the Antares rocket undergoing a redesign following its failure during the Orb-3 launch, OA-4 was launched by an Atlas V rocket. Following three launch delays due to inclement weather beginning on 3 December 2015, OA-4 was launched at 21:44 UTC on 6 December 2015. With a lift off weight of 7,492 kilograms (16,517 lb), OA-4 became the heaviest payload ever launched on an Atlas V.
