Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Perseverance Mars rover used its right-front navigation camera to capture this first view over the rim of Jezero Crater on Dec. 10, 2024, the 1,354th Martian day, or sol, of the mission. The camera is facing west from a location nicknamed “Lookout Hill.”NASA/JPL-Caltech NASA’s Perseverance Mars rover captured this scene showing the slippery terrain that’s made its climb up to the rim of Jezero Crater challenging. Rover tracks can be seen trailing off into the distance, back toward the crater’s floor.NASA/JPL-Caltech The road ahead will be even more scientifically intriguing, and probably somewhat easier-going, now that the six-wheeler has completed its long climb to the top.
NASA’s Perseverance Mars rover has crested the top of Jezero Crater’s rim at a location the science team calls “Lookout Hill” and rolling toward its first science stop after the monthslong climb. The rover made the ascent in order to explore a region of Mars unlike anywhere it has investigated before.
Taking about 3½ months and ascending 1,640 vertical feet (500 vertical meters), the rover climbed 20% grades, making stops along the way for science observations. Perseverance’s science team shared some of their work and future plans at a media briefing held Thursday, Dec. 12, in Washington at the American Geophysical Union’s annual meeting, the country’s largest gathering of Earth and space scientists.
“During the Jezero Crater rim climb, our rover drivers have done an amazing job negotiating some of the toughest terrain we’ve encountered since landing,” said Steven Lee, deputy project manager for Perseverance at NASA’s Jet Propulsion Laboratory in Southern California. “They developed innovative approaches to overcome these challenges — even tried driving backward to see if it would help — and the rover has come through it all like a champ. Perseverance is ‘go’ for everything the science team wants to throw at it during this next science campaign.”
A scan across a panorama captured by NASA’s Perseverance Mars rover shows the steepness of the terrain leading to the rim of Jezero Crater. The rover’s Mastcam-Z camera system took the images that make up this view on Dec. 5. NASA/JPL-Caltech/ASU/MSSS Since landing at Jezero in February 2021, Perseverance has completed four science campaigns: the “Crater Floor,” “Fan Front,” “Upper Fan,” and “Margin Unit.” The science team is calling Perseverance’s fifth campaign the “Northern Rim” because its route covers the northern part of the southwestern section of Jezero’s rim. Over the first year of the Northern Rim campaign, the rover is expected to visit as many as four sites of geologic interest, take several samples, and drive about 4 miles (6.4 kilometers).
“The Northern Rim campaign brings us completely new scientific riches as Perseverance roves into fundamentally new geology,” said Ken Farley, project scientist for Perseverance at Caltech in Pasadena. “It marks our transition from rocks that partially filled Jezero Crater when it was formed by a massive impact about 3.9 billion years ago to rocks from deep down inside Mars that were thrown upward to form the crater rim after impact.”
This animation shows the position of NASA’s Perseverance Mars rover as of Dec. 4, 2024, the 1,347th Martian day, or sol, of the mission, along with the proposed route of the mission’s fifth science campaign, dubbed Northern Rim, over the next several years. NASA/JPL-Caltech/ESA/University of Arizona “These rocks represent pieces of early Martian crust and are among the oldest rocks found anywhere in the solar system. Investigating them could help us understand what Mars — and our own planet — may have looked like in the beginning,” Farley added.
First Stop: ‘Witch Hazel Hill’
With Lookout Hill in its rearview mirror, Perseverance is headed to a scientifically significant rocky outcrop about 1,500 feet (450 meters) down the other side of the rim that the science team calls “Witch Hazel Hill.”
“The campaign starts off with a bang because Witch Hazel Hill represents over 330 feet of layered outcrop, where each layer is like a page in the book of Martian history. As we drive down the hill, we will be going back in time, investigating the ancient environments of Mars recorded in the crater rim,” said Candice Bedford, a Perseverance scientist from Purdue University in West Layfette, Indiana. “Then, after a steep descent, we take our first turns of the wheel away from the crater rim toward ‘Lac de Charmes,’ about 2 miles south.”
Lac de Charmes intrigues the science team because, being located on the plains beyond the rim, it is less likely to have been significantly affected by the formation of Jezero Crater.
After leaving Lac de Charmes, the rover will traverse about a mile (1.6 kilometers) back to the rim to investigate a stunning outcrop of large blocks known as megabreccia. These blocks may represent ancient bedrock broken up during the Isidis impact, a planet-altering event that likely excavated deep into the Martian crust as it created an impact basin some 745 miles (1,200 kilometers) wide, 3.9 billion years in the past.
More About Perseverance
A key objective of Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, to help pave the way for human exploration of the Red Planet and as the first mission to collect and cache Martian rock and regolith.
NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The north polar region of Jupiter’s volcanic moon Io was captured by NASA’s Juno during spacecraft’s 57th close pass of the gas giant on Dec. 30, 2023. Data from recent flybys is helping scientists understand Io’s interior. Image data: NASA/JPL-Caltech/SwRI/MSSS
Image processing by Gerald Eichstädt A new study points to why, and how, Io became the most volcanic body in the solar system.
Scientists with NASA’s Juno mission to Jupiter have discovered that the volcanoes on Jupiter’s moon Io are each likely powered by their own chamber of roiling hot magma rather than an ocean of magma. The finding solves a 44-year-old mystery about the subsurface origins of the moon’s most demonstrative geologic features.
A paper on the source of Io’s volcanism was published on Thursday, Dec. 12, in the journal Nature, and the findings, as well as other Io science results, were discussed during a media briefing in Washington at the American Geophysical Union’s annual meeting, the country’s largest gathering of Earth and space scientists.
About the size of Earth’s Moon, Io is known as the most volcanically active body in our solar system. The moon is home to an estimated 400 volcanoes, which blast lava and plumes in seemingly continuous eruptions that contribute to the coating on its surface.
This animated tour of Jupiter’s fiery moon Io, based on data collected by NASA’s Juno mission, shows volcanic plumes, a view of lava on the surface, and the moon’s internal structure. NASA/JPL-Caltech/SwRI/Koji Kuramura/Gerald Eichstädt Although the moon was discovered by Galileo Galilei on Jan. 8, 1610, volcanic activity there wasn’t discovered until 1979, when imaging scientist Linda Morabito of NASA’s Jet Propulsion Laboratory in Southern California first identified a volcanic plume in an image from the agency’s Voyager 1 spacecraft.
“Since Morabito’s discovery, planetary scientists have wondered how the volcanoes were fed from the lava underneath the surface,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “Was there a shallow ocean of white-hot magma fueling the volcanoes, or was their source more localized? We knew data from Juno’s two very close flybys could give us some insights on how this tortured moon actually worked.”
The Juno spacecraft made extremely close flybys of Io in December 2023 and February 2024, getting within about 930 miles (1,500 kilometers) of its pizza-faced surface. During the close approaches, Juno communicated with NASA’s Deep Space Network, acquiring high-precision, dual-frequency Doppler data, which was used to measure Io’s gravity by tracking how it affected the spacecraft’s acceleration. What the mission learned about the moon’s gravity from those flybys led to the new paper by revealing more details about the effects of a phenomenon called tidal flexing.
This five-frame sequence shows a giant plume erupting from Io’s Tvashtar volcano, extending 200 miles (330 kilometers) above the fiery moon’s surface. It was captured over an eight-minute period by NASA’s New Horizons mission as the spacecraft flew by Jupiter in 2007.NASA/Johns Hopkins APL/SwRI Prince of Jovian Tides
Io is extremely close to mammoth Jupiter, and its elliptical orbit whips it around the gas giant once every 42.5 hours. As the distance varies, so does Jupiter’s gravitational pull, which leads to the moon being relentlessly squeezed. The result: an extreme case of tidal flexing — friction from tidal forces that generates internal heat.
“This constant flexing creates immense energy, which literally melts portions of Io’s interior,” said Bolton. “If Io has a global magma ocean, we knew the signature of its tidal deformation would be much larger than a more rigid, mostly solid interior. Thus, depending on the results from Juno’s probing of Io’s gravity field, we would be able to tell if a global magma ocean was hiding beneath its surface.”
The Juno team compared Doppler data from their two flybys with observations from the agency’s previous missions to the Jovian system and from ground telescopes. They found tidal deformation consistent with Io not having a shallow global magma ocean.
“Juno’s discovery that tidal forces do not always create global magma oceans does more than prompt us to rethink what we know about Io’s interior,” said lead author Ryan Park, a Juno co-investigator and supervisor of the Solar System Dynamics Group at JPL. “It has implications for our understanding of other moons, such as Enceladus and Europa, and even exoplanets and super-Earths. Our new findings provide an opportunity to rethink what we know about planetary formation and evolution.”
There’s more science on the horizon. The spacecraft made its 66th science flyby over Jupiter’s mysterious cloud tops on Nov. 24. Its next close approach to the gas giant will occur 12:22 a.m. EST, Dec. 27. At the time of perijove, when Juno’s orbit is closest to the planet’s center, the spacecraft will be about 2,175 miles (3,500 kilometers) above Jupiter’s cloud tops and will have logged 645.7 million miles (1.039 billion kilometers) since entering the gas giant’s orbit in 2016.
More About Juno
JPL, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. The Italian Space Agency (ASI) funded the Jovian InfraRed Auroral Mapper. Lockheed Martin Space in Denver built and operates the spacecraft. Various other institutions around the U.S. provided several of the other scientific instruments on Juno.

The telescope and instruments for NASA’s Nancy Grace Roman Space Telescope were recently integrated together on the observatory’s instrument carrier at the agency’s Goddard Space Flight Center in Greenbelt, Md. Next, the entire system will be joined to the Roman spacecraft. NASA/Chris Gunn NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s telescope and two instruments onto the instrument carrier, marking the completion of the Roman payload. Now the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will begin joining the payload to the spacecraft.
“We’re in the middle of an exciting stage of mission preparation,” said Jody Dawson, a Roman systems engineer at NASA Goddard. “All the components are now here at Goddard, and they’re coming together in quick succession. We expect to integrate the telescope and instruments with the spacecraft before the year is up.”
Engineers first integrated the Coronagraph Instrument, a technology demonstration designed to image exoplanets — worlds outside our solar system — by using a complex suite of masks and active mirrors to obscure the glare of the planets’ host stars.
Then the team integrated the Optical Telescope Assembly, which includes a 7.9-foot (2.4-meter) primary mirror, nine additional mirrors, and their supporting structures and electronics. The telescope will focus cosmic light and send it to Roman’s instruments, revealing billions of objects strewn throughout space and time. Roman will be the most stable large telescope ever built, at least 10 times more so than NASA’s James Webb Space Telescope and 100 times more than the agency’s Hubble Space Telescope. This will allow scientists to make measurements at levels of precision that can answer important questions about dark energy, dark matter, and worlds beyond our solar system.
Technicians install the primary instrument for NASA’s Nancy Grace Roman Space Telescope, called the Wide Field Instrument (at left), in the biggest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md. This marked the final step to complete the Roman payload, which also includes a Coronagraph instrument and the Optical Telescope Assembly.NASA/Chris Gunn With those components in place, the team then added Roman’s primary instrument. Called the Wide Field Instrument, this 300-megapixel infrared camera will give Roman a deep, panoramic view of the universe. Through the Wide Field Instrument’s surveys, scientists will be able to explore distant exoplanets, stars, galaxies, black holes, dark energy, dark matter, and more. Thanks to this instrument and the observatory’s efficiency, Roman will be able to image large areas of the sky 1,000 times faster than Hubble with the same sharp, sensitive image quality.
“It would be quicker to list the astronomy topics Roman won’t be able to address than those it will,” said Julie McEnery, the Roman senior project scientist at NASA Goddard. “We’ve never had a tool like this before. Roman will revolutionize the way we do astronomy.”
The telescope and instruments were mounted to Roman’s instrument carrier and precisely aligned in the largest clean room at Goddard, where the observatory is being assembled. Now, the whole assembly is being attached to the Roman spacecraft, which will deliver the observatory to its orbit and enable it to function once there.
At the same time, the mission’s deployable aperture cover — a visor that will shield the telescope from unwanted light — is being joined to the outer barrel assembly, which serves as the telescope’s exoskeleton.
“We’ve had an incredible year, and we’re looking forward to another one!” said Bear Witherspoon, a Roman systems engineer at NASA Goddard. “While the payload and spacecraft undergo a smattering of testing together, the team will work toward integrating the solar panels onto the outer barrel assembly.”
That keeps the observatory on track for completion by fall 2026 and launch no later than May 2027.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Watersheds on the U.S. Eastern Seaboard will be among the areas most affected by underground saltwater intrusion by the year 2100 due to sea level rise and changes in groundwater supplies, according to a NASA-DOD study. NASA’s Terra satellite captured this image on April 21, 2023. Intrusion of saltwater into coastal groundwater can make water there unusable, damage ecosystems, and corrode infrastructure.
Seawater will infiltrate underground freshwater supplies in about three of every four coastal areas around the world by the year 2100, according to a recent study led by researchers at NASA’s Jet Propulsion Laboratory in Southern California. In addition to making water in some coastal aquifers undrinkable and unusable for irrigation, these changes can harm ecosystems and corrode infrastructure.
Called saltwater intrusion, the phenomenon happens below coastlines, where two masses of water naturally hold each other at bay. Rainfall on land replenishes, or recharges, fresh water in coastal aquifers (underground rock and soil that hold water), which tends to flow below ground toward the ocean. Meanwhile, seawater, backed by the pressure of the ocean, tends to push inland. Although there’s some mixing in the transition zone where the two meet, the balance of opposing forces typically keeps the water fresh on one side and salty on the other.
Now, two impacts of climate change are tipping the scales in favor of salt water. Spurred by planetary warming, sea level rise is causing coastlines to migrate inland and increasing the force pushing salt water landward. At the same time, slower groundwater recharge — due to less rainfall and warmer weather patterns — is weakening the force moving the underground fresh water in some areas.
Worldwide Intrusion
Saltwater intrusion will affect groundwater in about three of every four coastal aquifers around the world by the year 2100, a NASA-DOD study estimates. Saltwater can make groundwater in coastal areas undrinkable and useless for irrigation, as well as harm ecosystems and corrode infrastructure.NASA/JPL-Caltech The study, published in Geophysical Research Letters in November, evaluated more than 60,000 coastal watersheds (land area that channels and drains all the rainfall and snowmelt from a region into a common outlet) around the world, mapping how diminished groundwater recharge and sea level rise will each contribute to saltwater intrusion while estimating what their net effect will be.
Considering the two factors separately, the study’s authors found that by 2100 rising sea levels alone will tend to drive saltwater inland in 82% of coastal watersheds studied. The transition zone in those places would move a relatively modest distance: no more than 656 feet (200 meters) from current positions. Vulnerable areas include low-lying regions such as Southeast Asia, the coast around the Gulf of Mexico, and much of the United States’ Eastern Seaboard.
Meanwhile, slower recharge on its own will tend to cause saltwater intrusion in 45% of the coastal watersheds studied. In these areas, the transition zone would move farther inland than it will from sea level rise — as much as three-quarters of a mile (about 1,200 meters) in some places. The regions to be most affected include the Arabian Peninsula, Western Australia, and Mexico’s Baja California peninsula. In about 42% of coastal watersheds, groundwater recharge will increase, tending to push the transition zone toward the ocean and in some areas overcoming the effect of saltwater intrusion by sea level rise.
All told, due to the combined effects of changes in sea level and groundwater recharge, saltwater intrusion will occur by century’s end in 77% of the coastal watersheds evaluated, according to the study.
Generally, lower rates of groundwater recharge are going to drive how far saltwater intrudes inland, while sea level rise will determine how widespread it is around the world. “Depending on where you are and which one dominates, your management implications might change,” said Kyra Adams, a groundwater scientist at JPL and the paper’s lead author.
For example, if low recharge is the main reason intrusion is happening in one area, officials there might address it by protecting groundwater resources, she said. On the other hand, if the greater concern is that sea level rise will oversaturate an aquifer, officials might divert groundwater.
Global Consistency
Co-funded by NASA and the U.S. Department of Defense (DOD), the study is part of an effort to evaluate how sea level rise will affect the department’s coastal facilities and other infrastructure. It used information on watersheds collected in HydroSHEDS, a database managed by the World Wildlife Fund that uses elevation observations from the NASA Shuttle Radar Topography Mission. To estimate saltwater intrusion distances by 2100, the researchers used a model accounting for groundwater recharge, water table rise, fresh- and saltwater densities, and coastal migration from sea level rise, among other variables.
Study coauthor Ben Hamlington, a climate scientist at JPL and a coleader of NASA’s Sea Level Change Team, said that the global picture is analogous to what researchers see with coastal flooding: “As sea levels rise, there’s an increased risk of flooding everywhere. With saltwater intrusion, we’re seeing that sea level rise is raising the baseline risk for changes in groundwater recharge to become a serious factor.”
A globally consistent framework that captures localized climate impacts is crucial for countries that don’t have the expertise to generate one on their own, he added.
“Those that have the fewest resources are the ones most affected by sea level rise and climate change,” Hamlington said, “so this kind of approach can go a long way.”
