Preparations for Next Moonwalk Simulations Underway (and Underwater)
European company apetito uses Neurala’s vision inspection software to ensure the quality of its prepared meals, such as green bean portions pictured here. The software evolved from code Neurala was developing more than a decade ago, with NASA funding, for a rover that could independently learn to traverse Martian terrain. Credit: Neurala Inc. Artificial intelligence software initially designed to learn and analyze Martian terrain is now at the heart of a system to monitor assembly lines on Earth.
The vision inspection software from Neurala Inc., an artificial intelligence company in Boston, Massachusetts, works with existing cameras, computers, and even cellphones to monitor the quality of products running along a conveyor belt, for instance.
“Our software can learn very quickly on a processor with a very small footprint, a skill we learned working with NASA,” said Neurala cofounder and CEO Massimiliano Versace. “By doing so, we enable vision inspection with whatever components are already available, deploying in minutes. In our exploration of the market, we realized that the manufacturing space had a precise need for this technology.”
Versace and Neurala (Spinoff 2018) began working with NASA more than a decade ago on a project funded through the Small Business Technology Transfer (STTR) program. NASA was interested in “adaptive bio-inspired navigation for planetary exploration,” and Versace and his team had been working on neural network AI software modeled on the human brain.
Focusing on a rover concept that could independently learn to traverse Martian terrain, Neurala went on to win STTR Phase II funding for the project. Additional money from a NASA Center Innovation Fund enabled the Neurala team to adapt its technology to drone navigation and collision avoidance.
In both the rover and the drone applications, the Neurala software could run on a small device on the vehicle itself, eliminating the delay of sending signals to a decision maker in another location. Since then, the company developed the software to help monitor assembly lines.
Onsite computing is an advantage in manufacturing, as well, where an assembly line may have a hundred items passing every minute, making visual inspections for quality control difficult.

Hubble Space Telescope data of Jupiter’s Great Red Spot spanning approximately 90 days. Credits:
NASA, ESA, Amy Simon (NASA-GSFC); Image Processing: Joseph DePasquale (STScI) Astronomers have observed Jupiter’s legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises – especially when NASA’s Hubble Space Telescope takes a close-up look at it.
Hubble’s new observations of the famous red storm, collected 90 days between December 2023 to March 2024, reveal that the GRS is not as stable as it might look. The recent data show the GRS jiggling like a bowl of gelatin. The combined Hubble images allowed astronomers to assemble a time-lapse movie of the squiggly behavior of the GRS.

This time-lapse movie is assembled from Hubble Space Telescope observations spanning approximately 90 days (between December 2023 and March 2024) when the giant planet Jupiter ranged from 391 million to 512 million miles from the Sun. Astronomers measured the Great Red Spot’s size, shape, brightness, color, and vorticity over a full oscillation cycle. The data reveal that the Great Red Spot is not as stable as it might look. It was observed going through an oscillation in its elliptical shape, jiggling like a bowl of gelatin. The cause of the 90-day oscillation is unknown.

“While we knew its motion varies slightly in its longitude, we didn’t expect to see the size oscillate. As far as we know, it’s not been identified before,” said Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, lead author of the science paper published in The Planetary Science Journal. “This is really the first time we’ve had the proper imaging cadence of the GRS. With Hubble’s high resolution we can say that the GRS is definitively squeezing in and out at the same time as it moves faster and slower. That was very unexpected, and at present there are no hydrodynamic explanations.”
Hubble monitors Jupiter and the other outer solar system planets every year through the Outer Planet Atmospheres Legacy program (OPAL) led by Simon, but these observations were from a program dedicated to the GRS. Understanding the mechanisms of the largest storms in the solar system puts the theory of hurricanes on Earth into a broader cosmic context, which might be applied to better understanding the meteorology on planets around other stars.

Simon’s team used Hubble to zoom in on the GRS for a detailed look at its size, shape, and any subtle color changes. “When we look closely, we see a lot of things are changing from day to day,” said Simon. This includes ultraviolet-light observations showing that the distinct core of the storm gets brightest when the GRS is at its largest size in its oscillation cycle. This indicates less haze absorption in the upper atmosphere.
“As it accelerates and decelerates, the GRS is pushing against the windy jet streams to the north and south of it,” said co-investigator Mike Wong of the University of California at Berkeley. “It’s similar to a sandwich where the slices of bread are forced to bulge out when there’s too much filling in the middle.” Wong contrasted this to Neptune, where dark spots can drift wildly in latitude without strong jet streams to hold them in place. Jupiter’s Great Red Spot has been held at a southern latitude, trapped between the jet streams, for the extent of Earth-bound telescopic observations.

The team has continued watching the GRS shrink since the OPAL program began 10 years ago. They predict it will keep shrinking before taking on a stable, less-elongated, shape. “Right now it’s over-filling its latitude band relative to the wind field. Once it shrinks inside that band the winds will really be holding it in place,” said Simon. The team predicts that the GRS will probably stabilize in size, but for now Hubble only observed it for one oscillation cycle.
The researchers hope that in the future other high-resolution images from Hubble might identify other Jovian parameters that indicate the underlying cause of the oscillation.
The results are being presented at the 56th annual meeting of the American Astronomical Society Division for Planetary Sciences, in Boise, Idaho.
Jupiter’s iconic Great Red Spot, a storm larger than Earth, has fascinated astronomers for over 150 years. But thanks to NASA’s Hubble Space Telescope, we’re now seeing this legendary storm in a whole new light. Recent observations show that the Great Red Spot is wobbling and fluctuating in size.

NASA’s Advanced Composite Solar Sail System is seen orbiting Earth in this 13-second exposure photograph, Monday, Sept. 2, 2024, from Arlington, Virginia. The mission team confirmed the spacecraft’s unique composite boom system unfurled its reflective sail on Thursday, Aug. 29, 2024, accomplishing a critical milestone in the agency’s demonstration of next-generation solar sail technology that will allow small spacecraft to “sail on sunlight.” Just as a sailboat is powered by wind in a sail, a spacecraft can use the pressure of sunlight on a solar sail for propulsion. This technology demonstration serves as a pathfinder for future missions powered by solar sail technology.NASA/Bill Ingalls Now that its reflective sail has deployed fully open in orbit, the Advanced Composite Solar Sail System can be seen in the night sky from many locations across the world!
Stargazers can join NASA’s #SpotTheSail campaign by using the NASA app on mobile platforms to find out when the spacecraft will be visible at their location. The app, which is free to use and available on iOS and Android, provides a location-specific schedule of upcoming sighting opportunities. A built-in augmented reality tool points users to the location of the spacecraft in real time.

Eclipsing binary stars point the way to exoplanets and many other discoveries. Be one of the first to join the new Eclipsing Binary Patrol project and help discover them! NASA/Goddard Space Flight Center Eclipsing binaries are special pairs of stars that cross in front of one another as they orbit—stars that take turns blocking one another from our view. At Eclipsing Binary Patrol, the newest NASA-funded citizen science project, you’ll have a chance to help discover these unusual pairs of objects.
In Eclipsing Binary Patrol, you’ll work with real data from NASA’s TESS (Transiting Exoplanet Survey Satellite) mission. TESS collects a lot of information! But computers sometimes struggle to tell when the data show us something unimportant, like background noise or objects that aren’t stars. With your help, we can identify the correct targets and gain deeper insights into the behavior of double star systems.
“I’ve never worked as a professional astronomer, but being part of the Eclipsing Binary Patrol allows me to work with real data and contribute to actual discoveries,” said Aline Fornear, a volunteer from Brazil. “It’s exciting beyond words to know that my efforts are helping with the understanding of star systems so far away, and potentially new worlds, too!”
As a volunteer at Eclipsing Binary Patrol, your work will help confirm when a particular target is indeed an eclipsing binary, verify its orbital period, and ensure the target is the true source of the detected eclipses. You’ll be essential in distinguishing genuine discoveries from false signals. To get involved, visit our page on the Zooniverse platform and start sciencing!

NASA Citizen Scientists Spot Object Moving 1 Million Miles Per Hour
This artist’s concept shows a hypothetical white dwarf, left, that has exploded as a supernova. The object at right is CWISE J1249, a star or brown dwarf ejected from this system as a result of the explosion. This scenario is one explanation for where CWISE J1249 came from. W.M. Keck Observatory/Adam Makarenko Most familiar stars peacefully orbit the center of the Milky Way. But citizen scientists working on NASA’s Backyard Worlds: Planet 9 project have helped discover an object moving so fast that it will escape the Milky Way’s gravity and shoot into intergalactic space. This hypervelocity object is the first such object found with the mass similar to or less than that of a small star.
Backyard Worlds uses images from NASA’s WISE, or Wide Field Infrared Explorer, mission, which mapped the sky in infrared light from 2009 to 2011. It was re-activated as NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) in 2013 and retired on Aug. 8, 2024.
A few years ago, longtime Backyard Worlds citizen scientists Martin Kabatnik, Thomas P. Bickle, and Dan Caselden spotted a faint, fast-moving object called CWISE J124909.08+362116.0, marching across their screens in the WISE images. Follow-up observations with several ground-based telescopes helped scientists confirm the discovery and characterize the object. These citizen scientists are now co-authors on the team’s study about this discovery published in the Astrophysical Journal Letters (a pre-print version is available here).
“I can’t describe the level of excitement,” said Kabatnik, a citizen scientist from Nuremberg, Germany. “When I first saw how fast it was moving, I was convinced it must have been reported already.”
CWISE J1249 is zooming out of the Milky Way at about 1 million miles per hour. But it also stands out for its low mass, which makes it difficult to classify as a celestial object. It could be a low-mass star, or if it doesn’t steadily fuse hydrogen in its core, it would be considered a brown dwarf, putting it somewhere between a gas giant planet and a star.
Ordinary brown dwarfs are not that rare. Backyard Worlds: Planet 9 volunteers have discovered more than 4,000 of them! But none of the others are known to be on their way out of the galaxy.
This new object has yet another unique property. Data obtained with the W. M. Keck Observatory in Maunakea, Hawaii, show that it has much less iron and other metals than other stars and brown dwarfs. This unusual composition suggests that CWISE J1249 is quite old, likely from one of the first generations of stars in our galaxy.
Why does this object move at such high speed? One hypothesis is that CWISE J1249 originally came from a binary system with a white dwarf, which exploded as a supernova when it pulled off too much material from its companion. Another possibility is that it came from a tightly bound cluster of stars called a globular cluster, and a chance meeting with a pair of black holes sent it soaring away.
“When a star encounters a black hole binary, the complex dynamics of this three-body interaction can toss that star right out of the globular cluster,” says Kyle Kremer, incoming assistant professor in UC San Diego’s Department of Astronomy and Astrophysics.
Scientists will look more closely at the elemental composition of CWISE J1249 for clues about which of these scenarios is more likely.
This discovery has been a team effort on multiple levels—a collaboration involving volunteers, professionals, and students. Kabatnik credits other citizen scientists with helping him search, including Melina Thévenot, who “blew my mind with her personal blog about doing searches using Astronomical Data Query Language,” he said. Software written by citizen scientist Frank Kiwy was also instrumental in this finding, he said.
The study is led by Backyard Worlds: Planet 9 science team member Adam Burgasser, a professor at the University of California, San Diego, and includes co-authors Hunter Brooks and Austin Rothermich, astronomy students who both began their astronomy careers as citizen scientists.
