Troubled Boeing Starliner headed back to factory, further delaying NASA launch

A persistent valve problem remains after the issue scrubbed a second launch attempt earlier this month.

After more than a week trying to fix a problem with stuck valves, Boeing’s Starliner crew capsule is coming off the Atlas V rocket that was meant to send it to orbit for some «deeper-level troubleshooting.» In a call with media on Friday, NASA’s Steve Stich said Starliner now won’t be able to undertake its test flight to the International Space Station until late October at the earliest.

Boeing had hoped to launch Starliner on Aug. 3 in an attempt to dock with the ISS, but the attempt was scrubbed — the second delay in less than a week. Boeing’s first try way back in December 2019 failed to reach the correct orbit but gave it valuable data.

Engineers «detected unexpected valve position indicationsin the propulsion system» during a health check of the spacecraft after electrical storms in the region, Boeing said at the time. It remainsuncertain if the storms were responsible for the technical issue.

The spacecraft was moved off the pad and returned to a hangar (or»vertical integration facility») on Aug. 4 but as of Friday, four valves were still malfunctioning, forcing Boeing to de-stack the vehicle to get a better look at the problem.

«We’ll continueto work the issue from the Starliner factory,» Boeing’s Commercial Crew Program manager John Vollmer said.

He also cast some doubt on the possibility that the capsule will get off the ground in 2021: «It’s probably too early to say whether it’s this year, or not.»

The mission was originally scheduled to take off July 30, but that was delayed due to an issue Thursday with a Russian ISS module firing its thrusters shortly after docking with the station. That knocked the space station around and forced teams to evaluate the station’s status.

When Starliner does finally launch, it will lift off on a United Launch Alliance (ULA) Atlas V rocket. The capsule will be packed with around 400 pounds of crew supplies and cargo. If all goes well, it’ll dock with the space station about 24 hours later. Docking will also be covered live by NASA TV.

Software defects and a communications link problem led to a premature end to the original Boeing test flight in 2019, though the CST-100 Starliner capsule landed safely back on Earth. The upcoming Orbital Flight Test-2 (OFT-2) mission is a chance for Boeing to thoroughly vet its hardware and software before a crew of three American astronauts would fly on Starliner.

Both Boeing and SpaceX are part of NASA’s Commercial Crew Program, which is all about sending astronauts to the ISS from American soil. SpaceX has now delivered 10 astronauts to the ISS, and Boeing would like to catch up. But first, it’ll need to show that its Starliner can safely reach the ISS and return to Earth.

Starliner will spend between five and 10 days at the ISS before bringing research samples back to Earth. Boeing will aim to bring the spacecraft back for a parachute landing in the desert of New Mexico.

«OFT-2 will provide valuable data that will help NASA certify Boeing’s crew transportation system to carry astronauts to and from the space station,» NASA said in a statement July 22 after concluding a flight readiness review.

The mission is a key step for NASA’s plans to run regular crewed launches from the US, ending its reliance on Russian Soyuz spacecraft. Boeing is also looking ahead at its first crewed mission, Boe-CFT, which it had been hoping to launch within the next six months. The delays with OFT-2 could mean a longer wait before people fly on Starliner.

Ultrahuman Ring Pro Brings Better Battery Life, More Action and Analysis

The company’s new flagship smart ring stores more data, too. But that doesn’t really help Americans.

Sick of your smart ring’s battery not holding up? Ultrahuman’s new $479 Ring Pro smart ring, unveiled on Friday, offers up to 15 days of battery life on a single charge. The Ring Pro joins the company’s $349 Ring Air, which boosts health tracking, thanks to longer battery life, increased data storage, improved speed and accuracy and a new heart-rate sensing architecture. The ring works in conjunction with the latest Pro charging case.

Ultrahuman also launched its Jade AI, which can act as an agent based on analysis of current and historical health data. Jade can synthesize data from across the company’s products and is compatible with its Rings.

«With industry-leading hardware paired with Jade biointelligence AI, users can now take real-time actionable interventions towards their health than ever before,» said Mohit Kumar, CEO of Ultrahuman.

No US sales

That hardware isn’t available in the US, though, thanks to the ongoing ban on Ultrahuman’s Rings sales here, stemming from a patent dispute with its competitor, Oura Ring. It’s available for preorder now everywhere else and is slated to ship in March. Jade’s available globally.

Ultrahuman says the Ring Pro boosts battery life to about 15 days in Chill mode — up to 12 days in Turbo — compared to a maximum of six days for the Air. The Pro charger’s battery stores enough for another 45 days, which you top off with Qi-compatible wireless charging. In addition, the case incorporates locator technology via the app and a speaker, as well as usability features such as haptic notifications and a power LED.

The ring can also retain up to 250 days of data versus less than a week for the cheaper model. Ultrahuman redesigned the heart-rate sensor for better signal quality. An upgraded processor improves the accuracy of the local machine learning and overall speed.

It’s offered in gold, silver, black and titanium finishes, with available sizes ranging from 5 to 14.

Jade’s Deep Research Mode is the cross-ecosystem analysis feature, which aggregates data from Ring and Blood Vision and the company’s subscription services, Home and M1 CGM, to provide historical trends, offer current recommendations and flag potential issues, as well as trigger activities such as A-fib detection. Ultrahuman plans to expand its capabilities to include health-adjacent activities, such as ordering food.

Some new apps are also available for the company’s PowerPlug add-on platform, including capabilities such as tracking GLP-1 effects, snoring and respiratory analysis and migraine management tools.
