Intelsat 901 Satellite Returns to Service Using Northrop Grumman's Mission Extension Vehicle

Intelsat announced Friday that Intelsat 901 has returned to service following the successful docking with the first Mission Extension Vehicle (MEV-1) from Northrop Grumman Corporation and the company's wholly-owned subsidiary, SpaceLogistics LLC, on February 25 - the first time that two commercial spacecraft docked in geostationary orbit. Since the February rendezvous, MEV-1 has assumed navigation of the combined spacecraft stack reducing its inclination by 1.6 degrees and relocating IS-901 to its new orbital location. Intelsat then transitioned roughly 30 of its commercial and government customers to the satellite on April 2. The transition of service took approximately six hours. IS-901 is now operating at the 332.5E orbital slot and providing full service to Intelsat customers. Intelsat views life-extension services, like MEV technology, as a cost-effective and efficient way to minimize service disruptions, enhance the overall flexibility of its satellite fleet and better support the evolving needs of its customers. "With a focus on providing the best customer experience in our industry, Intelsat is proud to have pioneered this innovative first with Northrop Grumman. We see increased demand for our connectivity services around the world, and preserving our customers' experience using innovative technology such as MEV-1 is helping us meet that need," said Intelsat Chief Services Officer Mike DeMarco. "I want to thank Northrop Grumman, SpaceLogistics and our valued Intelsat customers, who put their trust in us to successfully execute this historic mission. As commercial space-servicing technology progresses, Intelsat looks forward to pioneering new applications in support of our customers' continued success."

"Our partnership with Intelsat was critical to delivering this innovative satellite technology into operation," said Tom Wilson, vice president, Northrop Grumman Space Systems and president, SpaceLogistics, LLC.

"This historic event, highlighted by the first in-orbit rendezvous and docking of two commercial satellites and the subsequent repositioning of the two-spacecraft stack, demonstrates the business value that MEV offers to customers. Now that MEV-1 has successfully delivered on its mission to place the Intelsat 901 satellite back into operational service, we will continue to pioneer the future of on-orbit servicing through our multi-year technology roadmap leading to additional services such as inspection, assembly and repair."

Under the terms of the contract, Northrop Grumman and SpaceLogistics will provide five years of life extension services to IS-901 before returning the spacecraft to a final decommissioned orbit.

MEV-1 will then be available to provide additional mission extension services for new clients including orbit raising, inclination corrections and inspections. Intelsat has already also contracted with Northrop Grumman for a second MEV (MEV-2) to service Intelsat 1002 satellite later this year.

OmegA on track to support certification launch in 2021

Northrop Grumman Corporation has conducted a full-scale static fire test of the second stage of its OmegA rocket in Promontory, Utah. Developed to support the U.S. Space Force's National Security Space Launch program, the OmegA Launch System remains on track for its first certification flight in spring 2021. During the test, the second stage motor fired for full-duration, approximately 140 seconds, burning nearly 340,000 pounds of solid propellant to produce upwards of 785,000 pounds of thrust. The test verified the motor's ballistics and thermal performance as well as steering control and performance in a cold-conditioned environment. The test team collected more than 500 channels of data to aid in verifying the motor. "Northrop Grumman designed OmegA to use the most reliable propulsion available to ensure exceptional mission assurance for our customers," said Charlie Precourt, vice president, propulsion systems, Northrop Grumman. "The firing is a significant accomplishment that demonstrates a domestic solution for the RD-180 rocket engine replacement." In October 2018, the U.S. Air Force awarded Northrop Grumman a $792 million Launch Services Agreement to complete detailed design and verification of the OmegA space launch vehicle and launch sites. The cold test, in conjunction with the successful hot static fire in May 2019, subjected OmegA's motors to the most extreme propellant temperatures the rocket will experience during storage, transport, stacking and launch.

Northrop Grumman has leveraged its flight proven technologies and extensive experience launching critical payloads in the development of the OmegA launch system. The rocket was designed to accommodate national security payloads while also serving the civil and commercial markets.

In preparation for OmegA's inaugural flight, Northrop Grumman now occupies High Bay 2 as the first commercial tenant in NASA's historic Vehicle Assembly Building at Kennedy Space Center. Construction crews are currently modifying Mobile Launch Platform-3 to serve as OmegA's assembly and launch platform at Pad 39B.
