Cygnus freighter’s ISS-boosting engine burn ends early

A planned reboost maneuver of the International Space Station ended after just 5 seconds for reasons currently unknown.

Cargo ships docked to the International Space Station regularly fire their thrusters in short bursts to keep the orbiting laboratory at its cruising altitude. Typically, these vehicles are Russian Progress capsules, but on Monday (June 20), a Northrop Grumman Cygnus vehicle was scheduled to complete a five-minute burn to evaluate whether the capsule is ready to take this duty on regularly.

The engine began firing at 11:20 a.m. EDT (1520 GMT) but shut down after just five seconds, according to a NASA statement (opens in new tab). Northrop Grumman isn’t sure yet what caused the abort, the agency noted.

The glitch isn’t an issue for the seven astronauts living and working on the International Space Station, the agency emphasized. “The Expedition 67 crew, which was never in any danger, is continuing its regular regime of work aboard the complex, which is orbiting around 260 miles [418 kilometers] above the Earth,” officials wrote.

Today’s maneuver had originally been scheduled to occur on Saturday (June 18), but was delayed after a Progress capsule docked to the orbiting laboratory conducted a 4.5-minute long boost on Thursday (June 16) to ensure that the station avoided a piece of debris.

Scientists estimated that the debris, likely a remnant of Russia’s November 2021 anti-satellite test, might have come as close as 0.5 miles (0.8 km) to the station without the protective maneuver.

The Cygnus capsule currently in orbit arrived at the laboratory in February. Astronauts have been packing the vehicle with trash in advance of its planned destruction in Earth’s atmosphere later this month. But before that happens, NASA wants to notch the reboost attempt, which is meant to become standard practice for Cygnus vehicles.

“NASA and Northrop Grumman flight controllers are reviewing data from today’s attempt and will develop a plan for the next steps needed to continue development of this enhanced capability as a standard service for NASA,” agency officials wrote in today’s statement.

Jetmakers push freighters, 787 timing in hands of regulators

DUBAI, Nov 13 (Reuters) – Boeing (BA.N) said on Saturday it was in advanced talks to sell a cargo version of its future 777X jetliner jet while Airbus predicted an A350 freighter deal soon, as aerospace giants eye a post-pandemic boom in e-commerce.

Boeing also indicated it was nearing the end of production snags on the 787 Dreamliner, but said the timing of any return to normal deliveries was strictly in the hands of regulators.

“We are in pretty advanced discussions with a number of customers. The (777X freighter) looks good from a design standpoint and a requirements standpoint,” Ihssane Mounir, senior vice president of commercial sales and marketing, said.

The U.S. planemaker is poised to launch what it says would be the world’s largest and most capable new freighter, while European rival Airbus (AIR.PA) is seeking buyers for an A350 cargo version that it describes as lighter and more efficient.

Airbus expects to announce a launch order for the A350 freighter “soon,” Chief Commercial Officer Christian Scherer told a separate news conference on the eve of the Dubai Airshow.

“I am quite happy with the market response around the world and in the region to the A350 freighter,” he added.

The 777X freighter is expected to be based on the smaller of two versions of the 777X family, known as the 777-8.

It had been expected to be launched only after the 777-8 passenger version, but Mounir said it could jump ahead of the 777-8, whose sales have lagged the main 777-9 variant.

Boeing is sticking to plans to deliver the 777-9 in 2023, Mounir said. The president of Dubai’s Emirates, the biggest customer for the 777X, has sharply criticised Boeing for around three years of delays and a lack of certainty on delivery dates.

REGULATORS’ CALL

Qatar Airways has said publicly it is in talks with Boeing over the possible purchase of a 777X freighter, while FedEx (FDX.N) is widely seen as another early contender. Airbus hopes to land an A350 cargo deal with Singapore Airlines (SIAL.SI).

Freighter traffic has increased as passenger jets that usually carry goods in the hold were grounded by the pandemic.

Mounir and Scherer, sales chiefs for the world’s two largest planemakers, both said a market recovery was under way, though doubts remain over demand for the largest wide-body jetliners.

Boeing is meanwhile approaching the resumption of deliveries of its 787 Dreamliner, after suspending them to deal with production flaws, and engaging with Chinese regulators over the re-certification of the 737 MAX in China, Mounir said.

But he stressed that Boeing would not pre-empt U.S. or Chinese regulators, who make final decisions on timing.

The 787 has been beset by production problems that have halted deliveries since May. In July, the Federal Aviation Administration said some 787s had a manufacturing quality issue.

The 737 MAX was cleared by major Western regulators late last year after an almost two-year safety grounding, but China has yet to allow it back to service.

“Whether the FAA or international regulators look at us and ask us questions … we will comply with those,” Mounir said.
