Orbital ATK returned to flight on October 17, 2016, launching a cargo shipment to the International Space Station from Virginia after a catastrophic explosion nearly two years prior. The successful mission supplied the orbiting laboratory with critical food and research materials.
Upgraded Antares Rocket Clears Wallops Flight Facility
Stakes ran exceptionally high on October 17, 2016, as Orbital ATK prepared for its first flight since a catastrophic launch failure nearly two years earlier. Despite initial scheduling setbacks, the newly upgraded Antares rocket lifted off into the night sky from NASA’s Wallops Flight Facility in Virginia, clearing the pad without incident.
The mission marked a crucial operational redemption for the company, which holds commercial resupply contracts with NASA. Sustaining continuous human habitation aboard the orbiting outpost depends on dependable, routine payload deliveries.
This particular seventh Cygnus cargo freighter flew in the Antares 230 configuration, utilizing two RD-181 first-stage engines paired with a Castor 30XL second stage on its sixth operational cargo delivery flight to the station, officially designated as OA-5. The liftoff itself followed a lengthy sequence of postponements that had previously pushed the schedule away from May 31, June 24, July 6, August 22, September, October 13, October 14, and October 16.
Sustaining Continuous Cargo Deliveries to the International Space Station
Maintaining a permanent human presence in orbit requires a steady cadence of supply runs from international partners.
For the American segment of the station, NASA relied on commercial resupply agreements with SpaceX alongside Orbital ATK, which later became Northrop Grumman Space Systems. Six days after liftoff from Virginia, the Cygnus cargo spacecraft successfully arrived at the complex to deliver food, supplies and science experiments essential for crew operations.
Although short periods can pass with adjustments in the absence of one or more vehicles, maintaining continuous space station operations requires the reliable rotation of key cargo haulers such as Progress, Cygnus, and Dragon. Following this successful outing, the Antares rocket would go on to fly another dozen times before requiring another stand-down for redesign work.
The Broader 2016 Global Launch Calendar
The October return-to-flight occurred amid a packed international launch manifest that year, featuring completed flights from spaceports around the globe. Space agencies and commercial providers dispatched numerous specialized payloads into orbit throughout the period.
For historical research, key missions from the 2016 Florida Space Coast manifest remain easily verifiable from official sources. These milestones include SpaceX launching SES-9 from Space Launch Complex 40 with a window opening at 6:35 p.m. Eastern on March 4, followed by NASA’s CRS-8 mission on April 8 sending nearly 7,000 pounds of cargo to the station while achieving the first successful drone-ship landing for SpaceX.
Later in the year, United Launch Alliance launched NASA’s OSIRIS-REx mission toward asteroid Bennu from Space Launch Complex 41 at 7:05 p.m. EDT on September 8. Another United Launch Alliance mission lifted off on November 19 carrying the GOES-R satellite aboard an Atlas V 541 rocket during a one-hour window opening at 5:42 p.m. EST, while NASA’s CYGNSS hurricane research mission launched on December 15 via a Pegasus XL air-launch over the Atlantic during a morning window.
| Date | Mission | Launch Site | Payload Objective |
|---|---|---|---|
| March 4, 2016 | SpaceX Falcon 9 | Space Launch Complex 40 | Launched the SES-9 communications satellite |
| April 8, 2016 | NASA CRS-8 | Cape Canaveral | Delivered nearly 7,000 pounds of cargo and tested a drone-ship landing |
| September 8, 2016 | United Launch Alliance Atlas V | SLC-41, Cape Canaveral | Dispatched the OSIRIS-REx mission toward asteroid Bennu |
| October 17, 2016 | Orbital ATK Antares | Wallops Flight Facility | Returned Cygnus cargo vehicle to flight operations for the space station |
Future Operational Milestones and Flight Plans
While the October mission restored vital capabilities to the American resupply fleet, heavy launch schedules continued across international spaceports through the final weeks of the year. Agencies maintained rigorous flight queues spanning Earth observation, navigation, and deep-space exploration.
Whether upcoming commercial vehicles will maintain uninterrupted launch cadences or face future hardware redesigns remains to be seen as flight programs progress.
