Antares 230 Stage Test Summary 4 5. Antares 230 Stage Test Overview The Antares 230 Stage Test was the major system-level verification activity prior to the OA-5 return to flight mission Similar to the Stage Test conducted in 2013 prior to the first flight of Antares, the test article was comprised of the integrated first stage of the Antares 230 launch vehicle The Test was performed at Pad 0A at Wallops Flight Facility Operation/Test objectives & description summary The Wet Dress Rehearsal verified and demonstrated all processes and operations required to properly configure the test article for engine ignition The Hot Fire test verified operation and performance of the integrated Antares 230 first stage featuring the upgraded RD-181 propulsion system − The Hot Fire test featured a 30 second duration firing of both RD-181 main engines at flight thrust levels − Mixture ratio excursions and TVC profiles were commanded during the Hot Fire test 5 6. Stage Test Overview (Pad Rollout) 6 7. Stage Test Completed 31 May 2016 7 8. OA-5 Mission Data Review Summary 8 9. Orbital ATK Combined Antares/Cygnus Team Has Heritage From Five Prior Flights 9 10. OA-5 Mission Summary OA-5 launched successfully from Wallops Flight Facility at 7:45pm EDT on 17 Oct 2016 within a 5 minute window Launch occurred on the first launch attempt All Antares mission requirements were achieved, including: Orbit insertion requirements Payload separation requirements Payload ground and flight environments In summary, OA-5 was a very successful mission with no identified flight anomalies 10 11. OA-5 Cygnus Mission Performance Excellent launch and injection from Antares First flight with two TriDARs Second flight of the NRCSD-E Second flight of NASA Saffire Experiment Cygnus successfully rendezvoused and berthed with ISS Stayed attached to ISS for 30 days Deployed four cubesats post departure 100 km above ISS No anomalies are being tracked Excellent Cygnus performance throughout the mission 11 12.
