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.

Want to Speak to Dolphins? Researchers Won $100,000 AI Prize Studying Their Whistling

The scientists studied a bottlenose dolphin community in Sarasota, Florida, uncovering evidence of language-like communications.

If any dolphins are reading this: hello!

A team of scientists studying a community of Florida dolphins has been awarded the first $100,000 Coller Dolittle Challenge prize, set up to award research in interspecies communication algorithms.

The US-based team, led by Laela Sayigh of the Woods Hole Oceanographic Institution, found that a type of whistle that dolphins employ is used as an alarm. Another whistle they studied is used by dolphins to respond to unexpected or unfamiliar situations. The team used non-invasive hydrophones to perform the research, which provides evidence that dolphins may be using whistles like words, shared with multiple members of their communities.

Capturing the sounds is just the beginning. Researchers will use AI to continue deciphering the whistles to try to find more patterns. 

«The main thing stopping us cracking the code of animal communication is a lack of data. Think of the 1 trillion words needed to train a large language model like ChatGPT. We don’t have anything like this for other animals,» said Jonathan Birch, a professor at the London School of Economics and Politics and one of the judges for the prize.

«That’s why we need programs like the Sarasota Dolphin Research Program, which has built up an extraordinary library of dolphin whistles over 40 years. The cumulative result of all that work is that Laela Sayigh and her team can now use deep learning to analyse the whistles and perhaps, one day, crack the code,» he said.

The award was part of a ceremony honoring the work of four teams from across the world. In addition to the dolphin project, researchers studied ways in which nightingales, marmoset monkeys and cuttlefish communicate.

The challenge is a collaboration between the Jeremy Coller Foundation and Tel Aviv University. Submissions for next year open up in August. 

Dolphins are just the beginning

Researching animals and trying to learn the secrets of their communication is nothing new; but AI is speeding up the creation of larger and lager datasets.

«Breakthroughs are inevitable,» says Kate Zacarian, CEO and co-founder of Earth Species Project, a California-based nonprofit that also works in breaking down language barriers with the animal world.

«Just as AI has revolutionized the fields of medicine and material science, we see a similar opportunity to bring those advances to the study of animal communication and empower researchers in this space with entirely new capabilities,» Zacarian said.

Zacarian applauded Sayigh’s team and their win and said it will help bring broader recognition to the study of non-human animal communication. It could also bring more attention to ways that AI can change the nature of this type of research.
«The AI systems aren’t just faster — they allow for entirely new types of inquiry,» she said. «We’re moving from decoding isolated signals to exploring communication as a rich, dynamic, and structure phenomenon — whish is a task that’s simply too big for our human brains, but possible for large-scale AI models.»

Earth Species recently released an open-source large audio language model for analyzing animal sounds called NatureLM-audio. The organization is currently working with biologists and ethologists to study species including carrion crows, orcas, jumping spiders and others and plans to release some of their findings later this year, Zacarian said.
