NASA testing advanced capabilities for moon, Mars rovers

On a bleak stretch of the Colorado Desert in Southern California, a compact four-wheeled rover recently trundled 16 miles (26 kilometers) with minimal intervention from the team of engineers trailing it. Called ERNEST (Exploration Rover for Navigating Extreme Sloped Terrain), this prototype is being used by NASA to advance both robotic autonomy and the ability to traverse challenging landscapes.

Developed at NASA’s Jet Propulsion Laboratory in Southern California, ERNEST is 4 feet (1.2 meters) long. Not only can it lift each of its mesh wheels to get past obstacles that would stymie Curiosity and Perseverance, NASA’s six-wheeled Mars rovers, but the prototype also has enhanced independent decision-making capabilities. These mobility and autonomy advances could be infused into future missions that will venture into previously inaccessible areas of the red planet or the moon.

In the field, ERNEST served as a testbed for a potential future lunar mission requiring higher speeds and much greater mileage than can be accomplished by current rovers. This technology could be used to inform future designs for exploration efforts on the moon and beyond.

New optical centrifuge unlocks the secrets of frictionless superfluids

Physicists have developed a new way to control the rotation of molecules inside tiny droplets of liquid helium, marking an important advance in the study of superfluids. By using a specially designed optical centrifuge, the team was able to precisely spin molecules suspended in liquid helium nano-droplets, giving scientists a powerful new tool for exploring these unusual frictionless materials.

The achievement represents the first successful demonstration of controlled molecular rotation inside a superfluid. Researchers can now directly adjust both the direction and speed of a molecule’s rotation, making it possible to investigate how molecules interact with their quantum surroundings at different rotational frequencies. The work, led by researchers at the University of British Columbia (UBC) in collaboration with the University of Freiburg, was published in Physical Review Letters.

“Controlling the rotation of a molecule dissolved in any fluid is a challenge,” said Dr. Valery Milner, associate professor with UBC Physics and Astronomy and author on the paper.

The Sun may not engulf Earth after all, scientists say

The Earth may not be engulfed by the expanding fireball of the dying sun, which has long been assumed to be our home planet’s ultimate fate, according to scientists.

Don’t worry: This is not expected to happen for another 5 billion years, long after all life on Earth has been wiped out.

When the sun burns through all of the hydrogen in its core, it will go through two immense expansion phases: first becoming a red giant, then, when its helium is spent, an “AGB” star.

We aren’t the authors of our thoughts. We’re just the user interface. We look at the universe and see a solid reality. The universe looks at us and sees a line of code. We spend our lives trying to leave a mark on the surface of reality. Oblivious to the fact that our existence is being computed from beneath. We aren’t separate individuals. We’re just the localized tips of a single, massive mathematical architecture.👇

A fully built

NASA announced on June 30, 2026, that it is considering sending PROMISE, an engineering test rover built at the Jet Propulsion Laboratory as a stand-in for the Curiosity and Perseverance Mars rovers, to the lunar surface. NASA Administrator Jared Isaacman, announcing the concept alongside a batch of new lunar lander contracts, framed the pitch as a matter of hardware already paid for. “We’ve had years now of experience operating the two rovers on the surface of Mars, and we’ve got this hardware that the taxpayers have invested a lot in,” Isaacman said, according to Space.com. “So the question was posed: what if we send it to the moon?” He introduced the idea with a line borrowed from Yoda: “There is another.”

XMM-Newton and Chandra help revise distance to Milky Way’s outer spiral arms

The European Space Agency’s XMM-Newton and NASA’s Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance to these echoes, they found the outer arms to be up to 10% farther away than previously thought.

Perhaps surprisingly, we don’t know much about the structure of our galaxy’s outer regions. It’s difficult to observe our galaxy from the inside: The solar system is well embedded in its disk, preventing a bird’s-eye view, and many regions are obscured by thick clouds of cosmic dust.

But this is changing: We have learned a huge amount since the launch of ESA’s star-surveying Gaia space telescope. Using data collected by Gaia, scientists are mapping the Milky Way galaxy in more detail than ever before by measuring precise distances to its stars. Before Gaia, we weren’t even sure whether our galaxy had two or four spiral arms (we now know the answer to be four).

Beyond 3D: Data scientists introduce novel AI tool to interpret complex biological data

As humans, our eyes take in two-dimensional images that our brains convert to three-dimensional experiences. This ability enables us to be aware of our position in space, judge distances, possess depth perception, and visually examine and enjoy all manner of objects and happenings.

But trying to envision subvisible structures and high-dimensional processes that our human-engineered scopes can’t capture is a challenge for data scientists and visualization experts, who turn to machine learning and AI tools to amplify visual exploration.

“Biological processes are an example of complex, high-dimensional data,” says Kevin Moon, director of USU’s Data Science and Artificial Intelligence (DSAI) Center and associate professor in the Department of Mathematics and Statistics.

Nearby super-Earth emerges as a top target in the search for life

Researchers have pinpointed a super-Earth in the habitable zone of a nearby M-dwarf star only 18 light-years away. Sophisticated instruments detected the planet’s gentle tug on its star, hinting at a rocky world that could hold liquid water. Future mega-telescopes may be able to directly image it—something impossible today.
