NASA’s Osiris-Rex Prepares to Deliver Asteroid Sample It Swiped in Space

A tiny load of cargo seven years in the making will touch down in the Utah desert later this month.

A pickpocketed piece of a big asteroid named Bennu is on its way back to Earth. NASA’s Osiris-Rex is winding down its mission more than seven years after launching from Cape Canaveral, Florida.

In 2020, the van-size spacecraft performed a «touch-and-go» maneuver — sort of like a chest bump in space — and swiped a few ounces of material from the space rock, which is really a pile of rubble held together by its own gravity. Osiris-Rex lingered around Bennu until 2021, when it started its two-year journey back to Earth.

The long flight ends on Sept. 24, when the spacecraft will jettison the capsule containing the sample. The capsule will then make a superheated trip through the atmosphere before parachuting in for a soft landing at the US military’s Utah Test and Training Range near Dugway, Utah.

Mission controllers have been preparing for the capsule’s return for months now. On Sept. 10, NASA reported the spacecraft briefly fired its thrusters to point itself toward Earth. The minor adjustment puts Osiris-Rex on course to release the capsule on a trajectory to enter our atmosphere off the coast of California at 7:42 a.m. PT on the delivery. About 13 minutes later it will touch down southwest of Salt Lake City somewhere in a predetermined area measuring 36 miles by 8.5 miles across.

The capsule will sizzle as it races through the sky protected by a heat shield. It will be tracked with thermal imaging equipment, and recovery teams will be deployed by helicopter to snatch it as quick as possible to avoid possible contamination from Earth’s environment.

Osiris-Rex is the first such mission led by NASA. Japan’s space agency sent two spacecraft, named Hayabusa and Hayabusa2, to collect and return samples from asteroids Itokawa and Ryugu, respectively.

The sample is set to arrive at Johnson Space Center in Houston after landing on Sept. 24, and there it will undergo preliminary analysis and be unveiled on Oct. 11 in a livestreamed news conference. It’s hoped the sample will provide scientists with a window into the birth of the solar system, including the sun and planets, some 4.5 billion years ago.

As for the main spacecraft, it isn’t done. After sending its treasure to the surface, Osiris-Rex will fire its engines to avoid smashing into the atmosphere itself. Instead, it will continue on to its next target, the asteroid Apophis, at which point it will be rechristened Osiris-Apex (Osiris-Apophis Explorer). The vehicle isn’t equipped to collect and return another sample, but it may try to blast the asteroid with its gas thrusters in an attempt to dislodge dust and other small bits for study.

Apophis is an important target because it’s considered a potentially hazardous asteroid. While any chance of it impacting Earth in the next century has been ruled out, it will be worth keeping a close eye on for centuries to come.

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.
