Antares - OA-8 - November 10, 2017
« on: 03/18/2017 02:20 AM »
Orbital ATK Antares Stands Ready to Support Eighth CRS Mission for NASA

As we prepare to launch the Cygnus OA-7 mission next week from Kennedy Space Center, Orbital ATK’s Antares team at NASA’s Wallops Flight Facility is making great progress on the company's eighth Cargo Resupply Mission (known as OA-8) to the International Space Station. The team plans to have Antares fully integrated and ready for the Cygnus payload by May.

“We are working a steady cadence at our home port in Wallops,” said Kurt Eberly, Antares Deputy Program Manager for Orbital ATK. “Our plan is to be ready in advance of when NASA needs us to fly.”

This week the team installed the aft bay over the fully integrated RD-181 engines on the first stage core. This milestone marks the completion of successful installation of all feed lines and completion of leak checks between the first stage core propellant tanks and the engines. The team has also completed all of the electrical system checks of the first stage.

In parallel, the large second stage Castor 30XL motor supplied by our Propulsion Systems Division in Utah has been going through mechanical integration including motor cone and avionics structure installations.

The Antares avionics structure is built and tested by the Orbital ATK team in Chandler, Arizona, then shipped to Wallops for integration. The avionics structure is fully populated with the components that control Antares during flight including the navigator, flight computer and telemetry systems.

OA-8 Fun Fact

The OA-8 mission will carry 3350kg of cargo to the space station onboard a Cygnus spacecraft. This will be the largest amount of cargo to be carried on an Antares mission to date and is the equivalent of sending more than three classrooms or 105 fifth graders to space!

“This program combines the best capabilities of our merged company with our propulsion and launch vehicles teams,” said Eberly. “For this mission we are really seeing the smooth operations that come from having a combined team of expertise that makes Orbital ATK.”

In May, the team will mate the first and second stage, complete flight simulation testing and then lift and transer the fully-assembled vehicle onto the Transporter/Erector/Launcher (TEL) where it will be ready for the Cygnus mate. The Antares team will be ready to launch OA-8 as early as this summer, and OA-9 as early as the end of this year. The specific launch dates for these missions will be selected jointly with NASA as we get closer to these time frames. Once OA-8 is complete, the Antares team will begin integrating the OA-9 vehicle.

“The goal of the program is to achieve an efficient, steady integration flow for the next set of Antares launches. Our Lanch Vehicles Division program personnel at Chandler and Dulles along with our Propulsion Systems Division motor team in Utah are critical to making sure that the fully integrated hardware assemblies and released software are delivered on time and in the right configuration to our field site to enable our operations team to execute the planned schedule activities each and every day,” said Eberly. “So a big thank you to everyone that supports the Antares program!”

Along with the vehicle integrations, Virginia Space has fully completed the pad readiness after the OA-5 flight last fall.

“Virginia Space is ready to support the upcoming missions, OA-8 and OA-9 from MARS,” said Dale Nash, Virginia Space Executive Director. “We look forward to getting Antares on the pad and ready to take cargo to the crews aboard the space station."

Is that a fueled Castor second stage in the second image? I would have expected solid motors to be handled separately from the liquid stages until stacking pre-launch. This isn't the case for Antares?

Yes that is a fueled motor.

Per Investor Relations info the use of that Core for OA-9 is certain baring any issues.

Replying to @jeff_foust

Thompson, in an earnings call this morning, said that means that next mission after this will slip to early 2018.

L2 has the "issue" as not enough cargo and NASA is finding more to send up. No point sending her up light.

I toured several facilities at Wallops last week, including the Cygnus facility, and there was no cargo loading going on. The empty cargo compartment was just sitting in the empty low bay.

The OA-8 mission is Orbital ATK’s eighth Commercial Resupply Services (CRS) mission to deliver supplies to the International Space Station, depicted by the shape of the patch being a numeral eight along with the yellow star at the top of the patch. This mission launches on an Antares rocket represented by the red, white and blue trajectory emanating from the Wallops Flight Facility on Virginia’s Eastern Shore.  The Cygnus spacecraft, with its solar panels deployed, is shown rising into orbit on the top left side of the 8.  The space station, where Cygnus will berth and deliver provisions and science experiments to the astronaut crew, is depicted on the top right side of the patch.  The Cygnus spacecraft for this mission is named in honor of former astronaut, (TBD), who is represented by the astronaut symbol to the left of the Earth. The name of the program and the customer are featured on the outer ring of the design.  This patch was designed by Orbital ATK employees, George Valuikas and Gary Burnside.
The name of the spacecraft will be revealed at a press event in mid-October.

That's a beautiful patch, better than the NASA-made SpaceX CRS ones (to me).
