Sols 4554–4555: Let’s Try That One Again… NASA’s Mars rover Curiosity acquired this image using its Front Hazard Avoidance Camera (Front Hazcam) on May 28, 2025 — Sol 4553, or Martian day 4,553 of the Mars Science Laboratory mission — at 04:48:55 UTC.

Earth planning date: Wednesday, May 28, 2025
We came in early this morning and learned that part of Tuesday’s plan didn’t execute on Mars due to a temporary issue with the arm. We collected APXS data on the target “Palo Verde Mountains,” but were not able to take the corresponding MAHLI images or drive away. So it was a straightforward decision for the planning team today to pick up where we left off yesterday, giving ourselves a second chance to collect the MAHLI observation and then complete the same 29.5-meter drive to the west (about 97 feet) that we had planned on Tuesday.
We love making lemonade from lemons when things don’t go exactly as expected in rover tactical planning, and today was no exception. Since we’re sticking around for a little bit longer, the science team decided to collect additional mosaics of impressive nearby features, including a 15×2 Mastcam mosaic of the “Mishe Mokwa” hill and an 11×2 Mastcam mosaic of fractures near “Lake Cachuma.” We’re also having another go at taking the epically long, long-distance RMI mosaic of a crater 91 kilometers away from Curiosity (almost 57 miles) that we planned yesterday, and we’re playing around with the focus settings to see if we can get a sharper image.
The team also had time for a second RMI mosaic of our very well-imaged “Texoli” butte, and a ChemCam LIBS observation on a target named “Santa Monica Bay,” which is just above the “Sisquoc River” target we observed yesterday on the bumpy rock in our workspace. As usual, we will also continue to monitor the environment around us with REMS, RAD, Navcam, and Mastcam observations.

NASA’s SpaceX Demo-2 Launch Fifth Anniversary
NASA’s SpaceX Demo-2 Launch Fifth Anniversary
President Donald Trump walks onstage to speak to a crowd at NASA’s Kennedy Space Center in Florida, following the launch of NASA’s SpaceX Demo-2 mission on May 30, 2020. The mission was the first crewed launch of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. This marked the first time American astronauts launched on an American rocket from American soil to low-Earth orbit since the conclusion of the Space Shuttle Program in 2011.

Hubble Spies Paired Pinwheel on Its Own This NASA Hubble Space Telescope image features the beautiful barred spiral galaxy NGC 3507 ESA/Hubble & NASA, D. ThilkerA single member of a galaxy pair takes centerstage in this NASA/ESA Hubble Space Telescope image. This beautiful spiral galaxy is NGC 3507, which is situated about 46 million light-years away in the constellation Leo (the Lion). NGC 3507’s classification is a barred spiral because the galaxy’s sweeping spiral arms emerge from the ends of a central bar of stars rather than the central core of the galaxy.
Though pictured solo here, NGC 3507 actually travels the universe with a galactic partner named NGC 3501 that is located outside the frame. While NGC 3507 is a quintessential galactic pinwheel, its partner resembles a streak of quicksilver across the sky. Despite looking completely different, both are spiral galaxies, simply seen from different angles.
For galaxies that are just a few tens of millions of light-years away, like NGC 3507 and NGC 3501, features like spiral arms, dusty gas clouds, and brilliant star clusters are on full display. More distant galaxies appear less detailed. See if you can spot any faraway galaxies in this image: they tend to be orange or yellow and can be anywhere from circular and starlike to narrow and elongated, with hints of spiral arms. Astronomers use instruments called spectrometers to split the light from these distant galaxies to study the nature of these objects in the early universe.
In addition to these far-flung companions, a much nearer object joins NGC 3507. The object is marked by four spikes of light: a star within the Milky Way, a mere 436 light-years away from Earth.

June’s Night Sky Notes: Seasons of the Solar System
NASA
by Kat Troche of the Astronomical Society of the Pacific
Here on Earth, we undergo a changing of seasons every three months. But what about the rest of the Solar System? What does a sunny day on Mars look like? How long would a winter on Neptune be? Let’s take a tour of some other planets and ask ourselves what seasons might look like there.
Martian AutumnAlthough Mars and Earth have nearly identical axial tilts, a year on Mars lasts 687 Earth days (nearly 2 Earth years) due to its average distance of 142 million miles from the Sun, making it late autumn on the red planet. This distance and a thin atmosphere make it less than perfect sweater weather. A recent weather report from Gale Crater boasted a high of -18 degrees Fahrenheit for the week of May 20, 2025.
Credit: NASA/JPL-Caltech Seven Years of SummerSaturn has a 27-degree tilt, very similar to the 25-degree tilt of Mars and the 23-degree tilt of Earth. But that is where the similarities end. With a 29-year orbit, a single season on the ringed planet lasts seven years. While we can’t experience a Saturnian season, we can observe a ring plane crossing here on Earth instead. The most recent plane crossing took place in March 2025, allowing us to see Saturn’s rings ‘disappear’ from view.
A Lifetime of Spring NASA Hubble Space Telescope observations in August 2002 show that Neptune’s brightness has increased significantly since 1996. The rise is due to an increase in the amount of clouds observed in the planet’s southern hemisphere. These increases may be due to seasonal changes caused by a variation in solar heating. Because Neptune’s rotation axis is inclined 29 degrees to its orbital plane, it is subject to seasonal solar heating during its 164.8-year orbit of the Sun. This seasonal variation is 900 times smaller than experienced by Earth because Neptune is much farther from the Sun. The rate of seasonal change also is much slower because Neptune takes 165 years to orbit the Sun. So, springtime in the southern hemisphere will last for several decades! Remarkably, this is evidence that Neptune is responding to the weak radiation from the Sun. These images were taken in visible and near-infrared light by Hubble’s Wide Field and Planetary Camera 2. Credit: NASA, L. Sromovsky, and P. Fry (University of Wisconsin-Madison)Even further away from the Sun, each season on Neptune lasts over 40 years. Although changes are slower and less dramatic than on Earth, scientists have observed seasonal activity in Neptune’s atmosphere. These images were taken between 1996 and 2002 with the Hubble Space Telescope, with brightness in the southern hemisphere indicating seasonal change.
As we welcome summer here on Earth, you can build a Suntrack model that helps demonstrate the path the Sun takes through the sky during the seasons. You can find even more fun activities and resources like this model on NASA’s Wavelength and Energy activity.

Sol 4553: Back to the Boxwork! NASA’s Mars rover Curiosity acquired this image of its workspace in the “boxwork” terrain area, showing resistant, ridge-like features where it will investigate the targets dubbed “Sisquoc River” and “Palo Verde Mountains.” Curiosity acquired the image using its Left Navigation Camera on May 27, 2025 — Sol 4552, or Martian day 4,552 of the Mars Science Laboratory mission — at 08:38:12 UTC. NASA/JPL-CaltechWritten by Lucy Thompson, Planetary Geologist at University of New Brunswick
Earth planning date: Tuesday, May 27, 2005
We return to planning today after a successful long weekend and about 42 meters of drive distance (about 138 feet). We planned four sols of activities on Friday to keep Curiosity busy, while the U.S.-based science team and engineers took time off yesterday for the Memorial Day holiday. As we got to admire the new workspace and drive direction view in front of the rover this morning, I realized that we have now driven about 35 kilometers (about 22 miles) and climbed more than 850 meters (2,789 feet) in elevation since landing nearly 13 years ago, and we continue to do exciting science on Mars, having recently driven onto new terrain.
The so-called boxwork structures are a series of resistant ridges observed both from orbit and in long-distance rover imaging (see Ashley’s blog here). Not only are the ridges of interest (do they indicate enhanced fluid-flow and cementation?), but the outcrop expression in general changed after we drove over a shallow trough onto the rocks that host the ridges.
This plan will continue characterization of the interesting boxwork terrain. We had an example of a more resistant, ridge-like feature in our workspace today (see accompanying image). The composition of the ridge will be investigated using ChemCam (target “Sisquoc River”) and APXS (target “Palo Verde Mountains”), with accompanying Mastcam and MAHLI images. We will also acquire Mastcam imaging of a trough-like feature surrounding a bedrock slab, as part of our ongoing documentation of such structures, as well as of an apparent resistant boxwork ridge in the distance (“Lake Cachuma”). And a first for our mission, we are planning the longest-distance ChemCam remote imaging mosaic that we will have acquired — 91 kilometers (almost 57 miles) away! The intent is to compare the long-distance view from the ground with HiRISE orbital images in an attempt to create a 3D view. We also managed to squeeze in a Navcam large dust-devil survey before the planned 24-meter drive (about 79 feet). Once we arrive at our new location, MARDI will take an image of the terrain beneath the rover.
The plan is rounded out with the standard REMS, DAN and RAD activities.

A Dust Devil Photobombs Perseverance! Perseverance self portrait, acquired by the WATSON camera on Sol 1500 on Mars. The Bell Island borehole where the rover acquired a sample is visible in the workspace in front of the rover. NASA/JPL-Caltech/MSSSWritten by Athanasios Klidaras, Ph.D. candidate at Purdue University, and Megan Kennedy Wu, Senior Mission Operations Specialist at Malin Space Science Systems
To celebrate her 1,500th Martian day (“Sol”) exploring the red planet, the Perseverance rover used its robotic arm to take a selfie of the rover and the surrounding landscape. But when team members reviewed the photo, they were surprised to find that Perseverance had been photobombed!
As the rover sat at the “Pine Pond” workspace, located on the outer rim of Jezero crater, which it has been exploring for the past several months, the Wide Angle Topographic Sensor for Operations and eNgineering (WATSON) camera on the end of its arm was used to acquire a 59-image mosaic of the rover. This is the fifth “selfie” that Perseverance has acquired since landing on Mars in 2021. The rover’s robotic arm is not visible in the self portrait because — just like a selfie you would take with your own cellphone camera — rover operators make sure not to have the arm get “in the way” of the body of the rover. This is even easier to do on Mars because Perseverance needs to take 59 different images at slightly different arm positions to build up the selfie, and the elbow of the robotic arm is kept out of the way while the images are acquired. You can find more details about the Sol 1500 selfie here, and this YouTube video shows how the rover arm moves when these activities take place.
While snapping away, Perseverance was photobombed by a dust devil in the distance! These are relatively common phenomena both on Mars and in Earth’s desert regions, and form from rising and rotating columns of warm air, which gives the appearance of a dust tornado. Just like many other weather patterns, there is a peak “season” for dust-devil activity, and Jezero crater is in the peak of that season now (late northern spring). The one seen in the selfie is fairly large, about 100 meters, or 328 feet, across. While Perseverance regularly monitors the horizon for dust-devil activity with Navcam movies, this is the first time the WATSON camera on the end of the robotic arm has ever captured an image of a dust devil!
The dark hole in front of the rover, surrounded by gray rock powder created during the drilling process, shows the location of Perseverance’s 26th sample. Nicknamed “Bell Island” after an island near Newfoundland, Canada, this rock sample contains small spherules, thought to have formed by volcanic eruptions or impacts early in Martian history. Later, this ancient rock was uplifted during the impact that formed Jezero crater. Now that the rover has successfully acquired the spherule sample the science team was searching for, Perseverance is leaving the area to explore new rock exposures. Last week, the rover arrived at an exposure of light-toned bedrock called “Copper Cove,” and the science team was interested to determine if this unit underlies or overlies the rock sequence explored earlier. After performing an abrasion to get a closer look at the chemistry and textures, the rover drove south to scout out more sites along the outer edge of the Jezero crater rim.

After performing an abrasion to get a closer look at the chemistry and textures, the rover drove south to scout out more sites along the outer edge of the Jezero crater rim.

NASA Tech Gives Treadmill Users a ‘Boost’
2 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Boost Treadmills cofounder Sean Whalen runs on the Boost 2. The treadmill uses air pressure to counter gravity, making running possible for people with injuries and other conditions.Credit: Boost Treadmills LLCThe antigravity treadmill, which has benefits in space and on Earth, was pioneered by Robert Whalen at NASA’s Ames Research Center in Silicon Valley, California, in the 1980s and ’90s.
Whalen built a system that placed a pressurized bulb over the user’s upper body, creating downward pressure that could simulate gravity for astronauts running on a treadmill in space. With support from Ames, he prototyped a treadmill in his garage that reversed the concept, with the bubble enclosing the user from the waist down to create lift. He thought the system could help patients rehabilitate.
Years later, his son recalled the prototype in the garage and turned it into the AlterG concept. The AlterG treadmill, which uses air pressure to take weight off the user, had proven popular with professional sports teams and rehabilitation clinics, but Whalen and his friends wanted to make it affordable enough for home use, so they founded Boost Treadmills in 2017.
Now Boost, based in Palo Alto, California, has cut the price of an antigravity treadmill by almost two thirds. In 2022, the company released the Boost 2, which is quieter and more energy-efficient than its predecessor, among other improvements. The Boost 2 has roughly tripled sales to individuals, progressing on the company’s goal of moving into the home.
Offloading weight during exercise is a clear solution for patients whose injuries prevent them from walking or running at their full weight, but Boost says it can be equally valuable for people with long-term mobility impairments, such as obesity or arthritis.
Advanced through NASA, the antigravity treadmill is one of many space-inspired technologies benefitting life on Earth.

45 Years Ago: NASA Announces Ninth Astronaut Group
45 Years Ago: NASA Announces Ninth Astronaut Group
Nearly all of NASA’s ninth class of astronaut candidates, along with two European trainees, poses for photos in the briefing room in the public affairs facility at NASA’s Johnson Space Center in Houston on July 7, 1980.
Group 9 was announced on May 29, 1980; the candidates would go on to make history in spaceflight and at NASA. For example, Charles Bolden (kneeling at far right) traveled to orbit four times aboard the space shuttle between 1986 and 1994, then became the agency’s first African American administrator in 2009. Franklin Chang-Diaz (fifth from the right, standing) was the first Hispanic American to fly in space and Jerry Ross (middle, standing in the back) was the first person to be launched into space seven times.
