This project will investigate and develop improved storage methods for the fuels needed to generate electrical power in places where sunlight is not available. The effort will focus on particularly tailored materials called Metal Oxide Frameworks, or MOFs, that can be used to store methane and oxygen. The methane and oxygen can be reacted in a solid oxide fuel cell to generate electricity, and storing them in a MOF could potentially result in significant mass and cost savings over traditional storage tanks which also require active pressure and thermal regulation. The team will use a number of computational and experimental tools to develop a MOF structure suitable for this application.

Sols 4505-4506: Up, up and onto the Devil’s Gate
This image was taken by Left Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4503 (2025-04-07 00:33:50 UTC). NASA/JPL-Caltech Written by Catherine O’Connell-Cooper, Planetary Geologist at University of New Brunswick
Earth planning date: Monday, April 7, 2025
Over the weekend, we completed our drive up the steep side of a canyon, up onto “Devil’s Gate,” a small butte which forms part of the ridge along the top of the canyon and now we can see down into the next canyon. It is always true that we are going somewhere no one has been before – that’s the idea of an exploratory mission after all, and everyone kind of gets used to it, we don’t stop to think about it. But today, coming over the top of a hill like this and fully looking for the first time into an area that we have only had glimpses of before, it really brings it home that the mission is doing something extraordinary, something out of this world …. and brings that feeling of awe back into focus.
We did not pass SRAP (Slip Risk Assessment Process) a couple of times as we climbed up the side of this canyon, meaning that the contact science instruments (APXS and MAHLI) had to stand down for that day’s planning. However, this morning, in addition to a brand new vista, we saw that all six wheels are firmly on the ground and we passed SRAP quickly this morning, which must have been a relief to the rover planner in charge of assessing it today! (no one wants to be the bearer of bad news, day after day!)
Bedrock here has both flat bedrock and amazing large nodular features, which appear to have “wind tails” caused by winds consistently blowing in the same direction. This is a Touch and Go plan, so APXS and MAHLI are focusing on a single target, the brushed “Coronado” target on the flat bedrock in front of us. ChemCam will use LIBS to investigate the nodular features at “La Cumbre Peak.”
Near the rover, Mastcam will image some small diagenetic features at “Boulder Oaks” and the LIBS target. The 3×2 (2 rows of 3 images) “La Jolla Valley” mosaic focuses on a very nodular patch, just outside of the workspace reachable by the arm. Further from the rover, the 6×2 mosaic (2 rows of 6 images) “Los Penasquitos” looks at an amazing almost vertical vein. This discontinuous vein stretches for about 6 meters (about 18 feet), with vein fins sticking above the surface at various points, like a series of shark fins breaking the bedrock surface. Much further afield, ChemCam will acquire a long distance image on “Condor Peak,” which appears to have large scale vein networks, known as “boxwork structures” and may be an early example of the boxworks we are hoping to reach in Fall 2025.
The ENV (Environmental and Atmospheric group) planned a Mastcam “tau” measurement, to look at dust in the atmosphere. There is a paired Navcam activity, looking at dust devils towards the north of the crater on the first sol and towards the south on the second sol. A suprahorizon movie and our usual DAN and REMS measurements round out this plan.
Let’s see what the next drive will reveal to us!

Sols 4502-4504: Sneaking Past Devil’s Gate
NASA’s Mars rover Curiosity acquired this image of the terrain around it on April 3, 2025, showing a small ridgeline on the right side, “Devil’s Gate,” and the base of Texoli butte, visible on the left side of the image. Curiosity acquired the image using its Left Navigation Camera on Sol 4500, or Martian day 4,500 of the Mars Science Laboratory mission, at 23:08:35 UTC.

Earth planning date: Friday, April 4, 2025
We continue to make progress driving up Mount Sharp, each day gaining new perspectives on the spectacular, towering buttes surrounding our path. To get to the next canyon we can ascend, we have to swing around the north end of a small ridgeline, “Devil’s Gate,” which is on the right side of the image above.
The blocks scattered around the base of Devil’s Gate are ripe with interesting structures, which motivated the acquisition of an RMI mosaic across the ridge. Those blocks are also inconvenient for driving and parking the rover with all six wheels firmly on the ground, the latter of which is needed to be able to unstow the arm for APXS and MAHLI observations. Our last drive ended with our front wheels not quite on solid ground, so we had to forego arm work this weekend. But as you can imagine with the view around us, Devil’s Gate was not the only feature that the team was excited to image. ChemCam added a second RMI mosaic along the base of “Texoli” butte, which you can see the flank of on the left side of the image above. Mastcam planned a mosaic across an expanse of bedrock that looks like rolling waves frozen in place at “Maidenhair Falls.”
The rocks right in front of the rover were also wonderfully complex in their textures and structures. ChemCam targeted two different textures expressed in the workspace — one across fine layers at “Arroyo Burro” and one across rough, platy, and gray material at “Arroyo Conejo.” Mastcam documented the block containing both these targets with a stereo mosaic that will give us a three-dimensional view of its structures.
We planned a drive to get us further around the base of Devil’s Gate, after which we will acquire an autonomously-targeted ChemCam LIBS raster and early morning Navcam and Mastcam mosaics looking back on the path we have recently traveled. DAN is scheduled for about seven hours of data collecting across the plan, both during science blocks and our drive. The sky gets a lot of attention in this plan with suites of observations taken at two different times — near midday and early morning — to assess variability across the day. Each window of time had Navcam dust-devil and cloud movies, and measurements of the amount of dust in the atmosphere. The early morning block of observations also had multiple cloud movies cover the full sky. REMS and RAD have regular measurements across the sols.
See you Monday, when we are a bit farther past Devil’s Gate!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This image shows about 1.5% of Euclid’s Deep Field South, one of three regions of the sky that the telescope will observe for more than 40 weeks over the course of its prime mission, spotting faint and distant galaxies. One galaxy cluster near the center is located almost 6 billion light-years away from Earth. ESA/Euclid/Euclid Consortium/NASA; image processing by J.-C. Cuillandre, E. Bertin, G. An-selmi With contributions from NASA, the mission is looking back into the universe’s history to understand how the universe’s expansion has changed.
The Euclid mission — led by ESA (European Space Agency) with contributions from NASA — aims to find out why our universe is expanding at an accelerating rate. Astronomers use the term “dark energy” to refer to the unknown cause of this phenomenon, and Euclid will take images of billions of galaxies to learn more about it. A portion of the mission’s data was released to the public by ESA released on Wednesday, March 19.
This new data has been analyzed by mission scientists and provides a glimpse of Euclid’s progress. Deemed a “quick” data release, this batch focuses on select areas of the sky to demonstrate what can be expected in the larger data releases to come and to allow scientists to sharpen their data analysis tools in preparation.
The data release contains observations of Euclid’s three “deep fields,” or areas of the sky where the space telescope will eventually make its farthest observations of the universe. Featuring one week’s worth of viewing, the Euclid images contain 26 million galaxies, the most distant being over 10.5 billion light-years away. Launched in July 2023, the space telescope is expected to observe more than 1.5 billion galaxies during its six-year prime mission.
The entirety of the Euclid mission’s Deep Field South region is shown here. It is about 28.1 square degrees on the sky. Euclid will observe this and two other deep field regions for a total of about 40 weeks during its 6-year primary mission. ESA/Euclid/Euclid Consortium/NASA; image processing by J.-C. Cuillandre, E. Bertin, G. An-selmi By the end of that prime mission, Euclid will have observed the deep fields for a total of about 40 weeks in order to gradually collect more light, revealing fainter and more distant galaxies. This approach is akin to keeping a camera shutter open to photograph a subject in low light.
The first deep field observations, taken by NASA’s Hubble Space Telescope in 1995, famously revealed the existence of many more galaxies in the universe than expected. Euclid’s ultimate goal is not to discover new galaxies but to use observations of them to investigate how dark energy’s influence has changed over the course of the universe’s history.
In particular, scientists want to know how much the rate of expansion has increased or slowed down over time. Whatever the answer, that information would provide new clues about the fundamental nature of this phenomenon. NASA’s Nancy Grace Roman Space Telescope, set to launch by 2027, will also observe large sections of the sky in order to study dark energy, complementing Euclid’s observations.
The location of the Euclid deep fields are shown marked in yellow on this all-sky view from ESA’s Gaia and Planck missions. The bright horizontal band is the plane of our Milky Way galaxy. Euclid’s Deep Field South is at bottom left.ESA/Euclid/Euclid Consortium/NASA; ESA/Gaia/DPAC; ESA/Planck Collaboration Looking Back in Time
To study dark energy’s effect throughout cosmic history, astronomers will use Euclid to create detailed, 3D maps of all the stuff in the universe. With those maps, they want to measure how quickly dark energy is causing galaxies and big clumps of matter to move away from one another. They also want to measure that rate of expansion at different points in the past. This is possible because light from distant objects takes time to travel across space. When astronomers look at distant galaxies, they see what those objects looked like in the past.
For example, an object 100 light-years away looks the way it did 100 years ago. It’s like receiving a letter that took 100 years to be delivered and thus contains information from when it was written. By creating a map of objects at a range of distances, scientists can see how the universe has changed over time, including how dark energy’s influence may have varied.
But stars, galaxies, and all the “normal” matter that emits and reflects light is only about one-fifth of all the matter in the universe. The rest is called “dark matter” — a material that neither emits nor reflects light. To measure dark energy’s influence on the universe, astronomers need to include dark matter in their maps.
Bending and Warping
Although dark matter is invisible, its influence can be measured through something called gravitational lensing. The mass of both normal and dark matter creates curves in space, and light traveling toward Earth bends or warps as it encounters those curves. In fact, the light from a distant galaxy can bend so much that it forms an arc, a full circle (called an Einstein ring), or even multiple images of the same galaxy, almost as though the light has passed through a glass lens.
In most cases, gravitational lensing warps the apparent shape of a galaxy so subtly that researchers need special tools and computer software to see it. Spotting those subtle changes across billions of galaxies enables scientists to do two things: create a detailed map of the presence of dark matter and observe how dark energy influenced it over cosmic history.
It is only with a very large sample of galaxies that researchers can be confident they are seeing the effects of dark matter. The newly released Euclid data covers 63 square degrees of the sky, an area equivalent to an array of 300 full Moons. To date, Euclid has observed about 2,000 square degrees, which is approximately 14% of its total survey area of 14,000 square degrees. By the end of its mission, Euclid will have observed a third of the entire sky.
The dataset released this month is described in several preprint papers available today. The mission’s first cosmology data will be released in October 2026. Data accumulated over additional, multiple passes of the deep field locations will also be included in the 2026 release.
More About Euclid
Euclid is a European mission, built and operated by ESA, with contributions from NASA. The Euclid Consortium — consisting of more than 2,000 scientists from 300 institutes in 15 European countries, the United States, Canada, and Japan — is responsible for providing the scientific instruments and scientific data analysis. ESA selected Thales Alenia Space as prime contractor for the construction of the satellite and its service module, with Airbus Defence and Space chosen to develop the payload module, including the telescope. Euclid is a medium-class mission in ESA’s Cosmic Vision Programme.
Three NASA-supported science teams contribute to the Euclid mission. In addition to designing and fabricating the sensor-chip electronics for Euclid’s Near Infrared Spectrometer and Photometer (NISP) instrument, JPL led the procurement and delivery of the NISP detectors as well. Those detectors, along with the sensor chip electronics, were tested at NASA’s Detector Characterization Lab at Goddard Space Flight Center in Greenbelt, Maryland. The Euclid NASA Science Center at IPAC (ENSCI), at Caltech in Pasadena, California, supports U.S.-based science investigations, and science data is archived at the NASA / IPAC Infrared Science Archive (IRSA). JPL is a division of Caltech.
