NASA’s Lucy blasts off on historic mission to Jupiter’s Trojan asteroids

The asteroids are 4.6-billion-year-old relics from the solar system’s earliest days.

A United Launch Alliance Atlas V 401 rocket flared to life under the cover of dark at Cape Canaveral Space Force Station in Floridajust after 2:30 a.m. local time Saturday morning. Encased within the pencil-shaped payload fairing atop the rocket was NASA’s latest interplanetary explorer: a spacecraft named Lucy.

It was the 100th launch from Cape Canaveral Space Launch Complex 41. Approximately 58 minutes after launch the probe, which is about as wide as a bus, was released from the second stage rocket booster to begin its long journey toward Jupiter’s orbit. The United Launch Alliance team celebrated with hugs and clapping in its mission control room.

«It was one of the most exciting experiences of my life,» Hal Levison, principal investigator of the Lucy mission, said post-launch. «It was truly awesome, in the old-fashioned meaning of the word.»

Over the next two years, Lucy will use Earth’s gravity twice to swing toward the solar system’s largest planet. But the gas giant isn’t Lucy’s destination. Instead, it’ll explore a series of asteroids, locked in Jupiter’s orbit, known as the Trojans.

These asteroids have never been studied up close before and move as huge swarms, or camps, at the «Lagrangian points» in Jupiter’s orbit. The Lagrangian points are regions where gravity’s push and pull lock the camps in place, leading and trailing Jupiter in its journey around the sun in perpetuity.

The collection of amorphous space rocks is like a series of cosmic fossils, providing a window into the earliest era of our solar system, some 4.6 billion years ago. Lucy will act as a cosmic palaeontologist, flying past these eight different «fossils» at a distance and studying their surfaces with infrared imagers and cameras.

«No spacecraft has visited so many objects before, and each is a potential window into the material and conditions of the early solar system,» says Alan Duffy, an astrophysicist at Swinburne University in Melbourne.

The idea of examining fossils is core to the mission’s philosophy — right down to its name. «Lucy» is derived from a hominid skeleton discovered in Ethiopia in 1974. The skeleton was dubbed Lucy because the Beatles’ song Lucy in the Sky With Diamonds was playing in the scientists’ camp after the find. Words from all four Beatles are contained on a plaque inside the spacecraft.

Though the early morning launch and separation was marked down as a success on Lucy’s extensive to-do list, the spacecraft had to overcome one final, giant hurdle before it was ready to sail out of Earth’s backyard. About one hour into its flight, the probe experienced «20 minutes of terror,» as it unfurled its 24 foot wide decagonal solar panels.

The panels are critical to the spacecraft’s success and will power Lucy during the 12-year journey toward the Trojans. They can supply about 500 watts of power — about the same amount of energy necessary to run a washing machine, according to NASA. And Lucy will need every watt, because it’ll be the farthest solar-powered spacecraft should it reach its destinations.

Ninety-one minutes after launch, the team acquired a signal from Lucy confirming the solar panels had deployed. «Things were splendid today,» said Omar Baez, the senior launch director of NASA’s Launch Services Program.

That means Lucy is alive and well and now there’s a lot of ground to cover before it reaches its first object of interest: Donaldjohanson, a space rock positioned in the asteroid belt between Mars and Jupiter. That flyby will occur in April 2025.

From there, Lucy will swing toward the Trojans, reaching four worlds throughout 2027 and 2028 in the Greek camp, the swarm of rocks leading Jupiter in orbit. Another Earth flyby will help propel Lucy to its final targets, Patroclus and its binary companion Menoetius, in the Trojan camp trailing Jupiter in 2033. In total, the spacecraft will cover 4 billion miles.

Lucy’s ambitious main mission won’t necessarily end with Patroclus and Menoetius, either. The spacecraft’s orbit will see it drift through the swarms for years to come. NASA has a good track record with extending missions — but you’ll have to keep your fingers crossed that everything goes well for the next decade.

Fitbit Launches Luffu, AI-Powered Health Tracking for the Whole Family

Soon, you may be able to access every family member’s health data in one place.

If you’ve ever wanted a way to keep all of your family’s health records in place, Fitbit may have come up with a solution. Fitbit, well-known for its fitness wearables, announced the launch of its own health care system on Wednesday.

Luffu, which translates to the Old English word for «love,» uses AI to create what it calls an «intelligent family care system.» The platform allows family members to share all their health information through an app.

It’s unclear when Luffu will be officially available, but you can sign up for the waitlist to get access to the limited public beta. Pricing or other details have not been announced.

Luffu will allow families to keep track of everyone’s doctor’s appointments, test results, vaccine records, medications, symptoms, diet and more. The platform uses AI to learn your family’s health history and patterns, and to alert you to any changes that should be addressed, such as missed medications or abnormal vitals. The AI function organizes the data submitted into the system. The app will also connect to third-party apps and wearables, such as the Fitbit.

Luffu is meant to lighten the mental load of family care by organizing all this health data in one place, its co-founder said.

«I was caring for my parents from across the country, trying to piece together my mom’s health care across various portals and providers, with a language barrier that made it hard to get a complete, timely context from her about doctor visits,» said Luffu co-founder James Park.

Luffu will include alerts and a space to log health and medication information via voice, text, photos, and other health portals and devices. The key medical information can be shared across the platform with spouses, caregivers and parents.

A representative for Fitbit did not immediately respond to a request for comment.

These New AI Transcription Models Are Built for Speed and Privacy

Mistral AI’s new Voxtral Mini Transcribe 2 and Voxtral Realtime are intended to run on your device, meaning your conversations never find their way to a data center.

Sometimes you want to transcribe something, but don’t want it to be hanging out on the internet for any hacker to see. Maybe it’s a conversation with your doctor or lawyer. Maybe you’re a journalist, and it’s a sensitive interview. Privacy and control are important.

That desire for privacy is one reason the French developer Mistral AI built its latest transcription models to be small enough to run on devices. They can run on your phone, on your laptop or in the cloud.

Voxtral Mini Transcribe 2, one of the new models announced Wednesday, is «super, super small,» Pierre Stock, Mistral’s vice president of science operations, told me. Another new model, Voxtral Realtime, can do the same thing but live, like closed captioning.

Privacy is not the only reason the company wanted to build small open-source models. By running right on the device you’re using, these models can work faster. No more waiting on files to find their way through the internet to a data center and back.

«What you want is the transcription to happen super, super close to you,» Stock said. «And the closest we can find to you is any edge device, so a laptop, a phone, a wearable like a smartwatch, for instance.»

The low latency (read: high speed) is especially important for real-time transcription. The Voxtral Realtime model can generate with a latency of less than 200 milliseconds, Stock said. It can transcribe a speaker’s words about as quickly as you can read them. No more waiting two or three seconds for the closed captioning to catch up.

The Voxtral Realtime model is available through Mistral’s API and on Hugging Face, along with a demo where you can try it out.

In some brief testing, I found it generated fairly quickly (although not as fast as you’d expect if it were on device) and managed to capture what I said accurately in English with a little bit of Spanish mixed in. It’s capable of handling 13 languages right now, according to Mistral.

Voxtral Mini Transcribe 2 is also available through the company’s API, or you can play around with it in Mistral’s AI Studio. I used the model to transcribe my interview with Stock.

I found it to be quick and pretty reliable, although it struggled with proper names like Mistral AI (which it called Mr. Lay Eye) and Voxtral (VoxTroll). Yes, the AI model got its own name wrong. But Stock said users can customize the model to understand certain words, names and jargon better if they’re using it for specific tasks.

The challenge of building small, fast AI models is that they also have to be accurate, Stock said. The company touted the models’ performance on benchmarks showing improved error rates compared to competitors.

«It’s not enough to say, OK, I’ll make a small model,» Stock said. «What you need is a small model that has the same quality as larger models, right?»
