NASA’s Mars rover Curiosity acquired this image showing faint tracks behind the rover on April 9, 2026. The mission team used autonomous navigation during the end of this drive, so Curiosity herself made the decision to take the turns visible in the images. The rover captured this image using its Left Navigation Camera on Sol 4861, or Martian day 4,861 of the Mars Science Laboratory mission, at 19:03:01 UTC.

Curiosity spent the past week driving towards a small crater, about 10 meters (32 feet) in diameter. Today the team informally named this crater “Antofagasta,” after a region and major city in Chile next to the Atacama. Craters are very cool for many reasons, one of which is that they act as “nature’s drill,” exposing material to the surface through their walls and ejecta that would have otherwise been buried. From orbit, Antofagasta looks like it might be a relatively young crater (less than 50 million years old, which is young on a Martian geologic scale!), so there may be material in and around the crater that was only exposed to the harsh, organic-molecule destroying radiation environment on Mars’ surface in the very recent past. Curiosity has already found many hardy organic molecules that survived billions of years, but could there be an even bigger treasure trove of complex chemistry deep below the surface? Antofagasta could help us answer this question… but only if the crater is big enough to have excavated deep rocks, if it really is relatively young, and if we are able to find a rock we are confident was excavated from depth that also meets the physical requirements for Curiosity’s drill. That’s a lot of “ifs,” but also too exciting of an opportunity to drive by! We’ll be able to answer all these “ifs” and decide what to do once we get a much closer look at the crater from the ground next week.

In the meantime, the journey to Antofagasta has been extremely interesting. Many of the rocks we’ve driven over have these incredible textures — thousands of honeycomb-shaped polygons crisscross their surface. Here’s one example, and here’s another example, both from Sol 4859. We’ve seen polygon-patterned rocks like these before, but they didn’t seem quite this dramatically abundant, stretching across the ground for meters and meters in our Mastcam mosaics. This week we continued to collect lots of images and chemical data that will help us distinguish between different hypotheses for how the honeycomb textures formed. We also continued to monitor Mars’ environment, with lots of dust-devil searches and images toward the horizon to characterize the Martian atmosphere as it grows predictably dustier approaching the warm summer months.

I’m looking forward to seeing the data that should arrive on Earth by Tuesday morning. If all goes well, Curiosity will be perched on the edge of Antofagasta, sending images that will allow us humans to see the crater rim and into the interior for the first time from the ground.

NASA Finds Young Stars Dim in X-rays Surprisingly Quickly

2026-04-14 20:34

The images of Trumpler 3, NGC 2353 & NGC 2301 represent a Chandra study that shows how young Sun-like stars are dimmer in X-rays than previously thought. Trumpler 3, NGC 2353 and NGC 2301 are open clusters that contains hundreds of young stars that are gravitationally bound together because they formed from the same gas cloud. Many of these stars have masses that are similar to our Sun but are much younger. In this composite image of the three clusters, X-rays from Chandra (purple) have been combined with an optical image from the PanSTARRS telescope in Hawaii (red, green, and blue). This result has implications for the prospects of life developing and surviving on planets in orbit around these stars.

Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal.

Unlike in the new movie “Project Hail Mary,” this quieting of young stars is a benefit for the prospects for life on orbiting planets around these stars — not a threat.

Astronomers used Chandra and other telescopes to monitor how powerful radiation from young stars — often in the form of dangerous X-rays — can pummel planets surrounding them. They did not know, however, how long this high-energy barrage continued.

This latest study looked at eight clusters of stars between the ages of 45 million and 750 million years old. The researchers found that Sun-like stars in these clusters unleashed only about a quarter to a third of the X-rays they expected.

“While science fiction – like the microbes in Project Hail Mary – imagines alien life that dims stellar output by consuming its energy, our real observations reveal a natural ‘quieting’ of young Sun-like stars in X-rays,” said Konstantin Getman, the lead author of the new study from Penn State University. “This is not because an outside force is consuming their light, but because their internal generation of magnetic fields becomes less efficient.”

In fact, this calming could be a boon to the formation of life on planets around stars that are younger versions of our own Sun. (Our Sun is about 4.6 billion years old, so significantly older than the stellar cousins in this study.) This is because large amounts of X-rays can erode a planet’s atmosphere and prevent formation of molecules necessary for organic life as we know it. On average, three-million-year-old stars with a mass equal to the Sun produce about a thousand times more X-rays than today’s Sun. Meanwhile, 100-million-year-old solar-mass stars are about 40 times brighter in X-rays than the present Sun.

“It’s possible that we owe our existence to our Sun doing the same thing, several billion years ago, that we see these young stars doing now,” said co-author Vladimir Airapetian of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This real-world dimming echoes the dramatic stellar change in fiction, but it may be even more fascinating because it highlights our own Sun’s actual history.”

The researchers found that stars with about the same mass as the Sun quieted down relatively rapidly — after a few hundred million years — while ones with less mass kept up their high levels of X-ray emission for longer. Combined with a decrease in the energy of the X-rays and the disappearance of energetic particles, the Sun-sized stars are apparently better suited to host planets with robust atmospheres and possibly blossoming life than previously thought.

The research team also used data from ESA’s (European Space Agency’s) Gaia satellite and X-ray data from the ROSAT (ROentgen SATellite) mission. This data allowed them to identify the stars that were members of the clusters (not foreground or background stars). To measure the X-ray output from the stars, they made new Chandra observations of five clusters with ages between 45 million and 100 million years, in addition to using Chandra and ROSAT data from archives to study three older clusters with ages between 220 and 750 million years.

Astronomers have not been able to study the X-ray output of stars in this age range well before. Most astronomers have relied on sparse data and a derived relation that predicts the X-ray emission young stars should produce based on their ages and rates of spin. Older and more slowly rotating stars are usually fainter in X-rays, but the team found that X-ray output drops off about 15 times more rapidly than the derived relation predicts during this specific adolescent phase.

“We can only see our Sun at this current snapshot in time, so to really understand its past we must look to other stars with about the same mass,” said co-author Eric Feigelson, also of Penn State University. “By studying X-rays from stars that are hundreds of millions of years old, we have filled in a large gap in our understanding of their evolution.”

While they are still investigating the cause of this slower-than-expected activity, scientists think the process that generates magnetic fields in these stars may become less efficient. This would lead to the stars becoming quieter in X-rays more quickly, as they age. The researchers will continue to look at this and other potential causes for the rapid dimming of young Sun-like stars.

NASA astronaut Christina Koch, Artemis II mission specialist, hugs the Orion spacecraft in the well deck of USS John P. Murtha, Saturday, April 11, 2026. NASA astronauts Reid Wiseman, Victor Glover, and Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen splashed down in the Pacific Ocean off the coast of California, on Friday, April 10.

After splashdown, the astronauts were met by a combined NASA and U.S. military team that assisted them out of the spacecraft in open water and transported them via helicopter to the USS John P. Murtha for initial medical checkouts. On April 11, the astronauts returned to the agency’s Johnson Space Center in Houston for a news conference.

Artemis II is the first crewed mission in the program. Lessons learned from this test flight will inform our return to the lunar surface and future missions to Mars. Learn more about the cadence for upcoming Artemis missions.
