OA-5 Mission Overview
Cargo Delivery for the International Space Station
Overview
The OA-5 mission is the sixth mission
undertaken by Orbital ATK to deliver crew
supplies, spare equipment and scientific
experiments to the International Space Station
under the NASA Cargo Resupply Service-1
(CRS-1) contract. For the CRS-1 contract
Orbital ATK will deliver approximately 30,000
kilograms (66,139 lb.) of cargo to the station,
and dispose of waste.
Cygnus Spacecraft
Antares Launch Vehicle
Cygnus Launch Mass:
6,173 kg (13,608 lb.)
Diameter: 3.9 m
Propellant Mass:
800 kg (1,764 lb.)
Height: 42.5 m
Ascent Cargo Mass:
2,425 kg (5,346 lb.)
Payload Fairing: 9.9 m
Pressurized Volume:
27 m3
Mass: Height:
6.39 m
Power Generation:
2 fixed wing "UltraFlex™"
solar arrays
Descent Cargo Mass:
1,687 kg (3,719 lb.)
Cargo is delivered to the station using
Orbital ATK’s Cygnus spacecraft. Cygnus
will be launched into orbit using Orbital ATK’s
upgraded Antares 230 launch vehicle from
Virginia Space’s Mid-Atlantic Regional
Spaceport Pad 0A on Wallops Island, Virginia at
NASA’s Wallops Flight Facility.
Cygnus Advanced
Maneuvering Spacecraft
Stage 2
Orbital ATK CASTOR® 30XL solid motor
Pressurized
Cargo Module
After being launched into low-Earth orbit, the
Cygnus spacecraft will transport the cargo from
a low parking orbit to the space station where it
will be grappled by the astronaut crew using the
station’s robotic arm and berthed to the station.
After the cargo is removed and any station
disposal items are added, Cygnus will depart
begin secondary payload missions.
For the OA-5 mission Cygnus carries the
Saffire-II payload experiment to study
combustion behavior in microgravity. In
addition, a NanoRacks deployer will release
several Cubesats. These secondary payload
operations will be conducted after Cygnus
departs the station.
