Sols 4304-4006: 12 Years, 42 Drill Holes, and Now… 1 Million ChemCam Shots! In celebration of ChemCam’s milestone, here is a stunning image from its remote micro imager, showing details in the landscape far away. This image was taken by Chemistry & Camera (ChemCam) onboard NASA’s Mars rover Curiosity on Sol 4302 — Martian day 4,302 of the Mars Science Laboratory mission — on Sept. 12, 2024, at 09:20:51 UTC. NASA/JPL-Caltech

Earth planning date: Friday, Sept. 13, 2024

Today, I need to talk about ChemCam, our laser and imaging instrument on the top of Curiosity’s mast. It one of the instruments in the “head” that gives Curiosity that cute look as if it were looking around tilting its head down to the rocks at the rover’s wheels. On Monday, 19th August the ChemCam team at CNES in France planned the 1 millionth shot and Curiosity executed it on the target Royce Lake on sol 4281 on Mars. Even as an Earth scientist used to really big numbers, this is a huge number that took me a while to fully comprehend. 1 000 000 shots! Congratulations, ChemCam, our champion for getting chemistry from a distance – and high-resolution images, too. If you are now curious how Curiosity’s ChemCam instrument works, here is the NASA fact sheet. And, of course, the team is celebrating, which is expressed by those two press releases, one from CNES in France and one from Los Alamos National Laboratory, the two institutions who collaborated to develop and build ChemCam and are now running the instrument for over 12 years! And the PI, Dr Nina Lanza from Los Alamos informs me that the first milestone – 10000 shots was reached as early as Sol 42, which was the sol the DAN instrument used its active mode for the first time. But before I am getting melancholic, let’s talk about today’s plan!

The drive ended fairly high up in the terrain, and that means we see a lot of the interesting features in the channel and generally around us. So, we are on a spot a human hiker would probably put the backpack down, take the water bottle out and sit down with a snack to enjoy the view from a nice high point in the landscape. Well, no such pleasures for Curiosity – and I am pretty sure sugar, which we humans love so much, wouldn’t be appreciated by rover gears anyway. So, let’s just take in the views! And that keeps Mastcam busy taking full advantage of our current vantage point. We have a terrain with lots of variety in front of us, blocks, boulders, flatter areas and the walls are layered, beautiful geology. Overall there are 11 Mastcam observations in the plan adding up to just about 100 individual frames, not counting those taken in the context of atmospheric observations, which are of course also in the plan. The biggest mosaics are on the targets “Western Deposit,” “Balloon Dome,” and “Coral Meadow.” Some smaller documentation images are on the targets “Wales Lake,” “Gnat Meadow,” and “Pig Chute.”

ChemCam didn’t have long to dwell on its milestone, as it’s busy again today. Of course, it will join Mastcam in taking advantage of our vantage point, taking three remote micro imager images on the landscape around us. LIBS chemistry investigations are targeting “Wales Lake,” “Gnat Meadow,” and “Pig Chute.” APXS is investigating two targets, “College Rock” and “Wales Lake,” which will also come with MAHLI documentation. With all those investigations together, we’ll be able to document the chemistry of many targets around us. There is such a rich variety of dark and light toned rocks, and with so much variety everywhere, it’s hard to choose and the team is excited about the three targeted sols … and planning over 4 hours of science over the weekend!

The next drive is planned to go to an area where there is a step in the landscape. Geologists love those steps as they give insights into the layers below the immediate surface. If you have read the word ‘outcrop’ here, then that’s what that means: access to below the surface. But there are also other interesting features in the area, hence we will certainly have an interesting workspace to look at! But getting there will not be easy as the terrain is very complex, so we cannot do it in just one drive. I think there is a rule of thumb here: the more excited the geo-team gets, the more skills our drivers need. Geologists just love rocks, but of course, no one likes driving offroad in a really rocky terrain – no roads on Mars. And right now, our excellent engineers have an extra complication to think about: they need to take extra care where and how to park so Curiosity can actually communicate with Earth. Why? Well, we are in a canyon, and those of you liking to hike, know what canyons mean for cell phone signals… yes, there isn’t much coverage, and that’s the same for Curiosity’s antenna. This new NASA video has more information and insights into the planning room, too! So, we’ll drive halfway to where we want to be but I am sure there will be interesting targets in the new workspace, the area is just so, so complex, fascinating and rich!

And that’s after Mars for you, after 12 years, 42 drill holes, and now 1 Million ChemCam shots. Go Curiosity go!!!

Editor’s note: This media advisory was updated Friday, Sept. 13, 2024, with a correct phone number for the media contact at NASA’s Glenn Research Center.

NASA‘s Watts on the Moon Challenge, designed to advance the nation’s lunar exploration goals under the Artemis campaign by challenging United States innovators to develop breakthrough power transmission and energy storage technologies that could enable long-duration Moon missions, concludes on Friday, Sept. 20, at the Great Lakes Science Center in Cleveland.

“For astronauts to maintain a sustained presence on the Moon during Artemis missions, they will need continuous, reliable power,” said Kim Krome-Sieja, acting program manager, Centennial Challenges at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “NASA has done extensive work on power generation technologies. Now, we’re looking to advance these technologies for long-distance power transmission and energy storage solutions that can withstand the extreme cold of the lunar environment.”

The technologies developed through the Watts on the Moon Challenge were the first power transmission and energy storage prototypes to be tested by NASA in an environment that simulates the extreme cold and weak atmospheric pressure of the lunar surface, representing a first step to readying the technologies for future deployment on the Moon. Successful technologies from this challenge aim to inspire, for example, new approaches for helping batteries withstand cold temperatures and improving grid resiliency in remote locations on Earth that face harsh weather conditions.

Media and the public are invited to attend the grand finale technology showcase and awards ceremony for the $5 million, two-phase competition. U.S. and international media interested in covering the event should confirm their attendance with Lane Figueroa by 3 p.m. CDT Tuesday, Sept. 17, at: lane.e.figueroa@nasa.gov. NASA’s media accreditation policy is available online. Members of the public may register as an attendee by completing this form, also by Friday, Sept. 17.

During the final round of competition, finalist teams refined their hardware and delivered a full system prototype for testing in simulated lunar conditions at NASA’s Glenn Research Center in Cleveland. The test simulated a challenging power system scenario where there are six hours of solar daylight, 18 hours of darkness, and the user is three kilometers from the power source.

“Watts on the Moon was a fantastic competition to judge because of its unique mission scenario,” said Amy Kaminski, program executive, Prizes, Challenges, and Crowdsourcing, Space Technology Mission Directorate at NASA Headquarters in Washington. “Each team’s hardware was put to the test against difficult criteria and had to perform well within a lunar environment in our state-of-the-art thermal vacuum chambers at NASA Glenn.”

Each finalist team was scored based on Total Effective System Mass (TESM), which determines how the system works in relation to its mass. At the awards ceremony, NASA will award $1 million to the top team who achieves the lowest TESM score, meaning that during testing, that team’s system produced the most efficient output-to-mass ratio. The team with the second lowest mass will receive $500,000. The awards ceremony stream live on NASA Glenn’s YouTube channel and NASA Prize’s Facebook page.

The Watts on the Moon Challenge is a NASA Centennial Challenge led by NASA Glenn. NASA Marshall manages Centennial Challenges, which are part of the agency’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate. NASA has contracted HeroX to support the administration of this challenge.

Sols 4302-4303: West Side of Upper Gediz Vallis, From Tungsten Hills to the Next Rocky Waypoint This photo taken by NASA’s Mars rover Curiosity of ‘Balloon Dome’ covers a low dome-like structure formed by the light-toned slab-like rocks. This image was taken by Left Navigation Camera aboard Curiosity on Sol 4301 — Martian day 4,301 of the Mars Science Laboratory mission — on Sept. 11, 2024, at 09:14:42 UTC. NASA/JPL-Caltech

Earth planning date: Wednesday, Sept. 11, 2024

The rover is on its way from the Tungsten Hills site to the next priority site for Gediz Vallis channel exploration, in which we plan to get in close enough for arm science to one of the numerous large dark-toned “float” blocks in the channel and also to one of the light-toned slabs.  We have seen some dark blocks in the channel that seem to be related to the Stimson formation material that the rover encountered earlier in the mission, but some seem like they could be something different. We don’t think any of them originated in the channel so they have to come from somewhere higher up that the rover hasn’t been, and we’re interested in how they were transported down into the channel.

We aren’t there yet, but the 4302-4303 plan’s activities include some important longer-range characterization of the dark-toned and light-toned materials via imaging. Context for the future close-up science on the dark-toned blocks will be provided by the Mastcam mosaics named “Bakeoven Meadow” and “Balloon Dome.”  The broad Balloon Dome mosaic also covers a low dome-like structure formed by the light-toned slab-like rocks (pictured).  Smaller mosaics will cover a pair of targets that include contacts where other types of light-toned and dark-toned material occur next to each other in the same block: “Rattlesnake Creek” which appears to be in place, and “Casa Diablo Hot Springs,” which is a float.

The rover’s arm workspace provided an opportunity for present-day aeolian science on the sandy-looking ripple, Sandy Meadow. Mastcam stereo imaging will document the shape of the ripple, while a suite of high-resolution MAHLI images will tell us something about the particle size of the grains in it.  The modern environment will also be monitored via a suprahorizon observation, a dust devil survey, and imaging of the rover deck to look for dust movement.

The workspace included small examples of the dark float blocks, so the composition of one of them will be measured by both APXS and ChemCam LIBS as targets “Lucy’s Foot Pass” and “Colt Lake” respectively.

In the meantime, the Mastcam Boneyard Meadow mosaic will provide a look back at the Tungsten Hills dark rippled block along its bedding plane to try to narrow down the origin of the ripples and the potential roles of water vs. wind in their formation.

Communication remains a challenge for the rover in this location. During planning, the rover’s drive was shifted from the second sol to the first sol in order to increase the downlink data volume available for the post-drive imaging, thereby enabling better planning at the science waypoint we expect to reach in the weekend plan. However, maintaining communications will require the rover to end its drive in a narrow range of orientations, which could make approaching our next science target a bit tricky.  We’ll find out on Friday!

The Digital Information Platform (DIP) Sub-Project of Air Traffic Management – eXploration (ATM-X) is seeking to make available in the National Airspace System a variety of live data feeds and services built on that data. The goal is to allow external partners to build advanced, data-driven services using this data and to make these services available to flight operators, who will use these capabilities to save fuel and avoid delays. Different wind directions, weather conditions at or near the airport, inoperative runway, etc., affects the runway configurations to be used and impacts the overall arrival throughputs. Knowing the arrival runway and its congestion level ahead of time will enable aviation operators to perform better flight planning and improve the flight efficiency. This competition seeks to make better predictions of runway throughputs using machine learning or other techniques. This competition engages students, faculty members, and other individuals employed by United States universities to develop a machine learning model that provides a short-term forecast of estimated airport runway throughput using simulated real-time information from historical NAS and weather forecast data, as well as other factors such as meteorological conditions, airport runway configuration, and airspace congestion.

Award: $120,000 in total prizes

4 Min Read NASA’s Artemis II Crew Uses Iceland Terrain for Lunar Training

Black and gray sediment stretches as far as the eye can see. Boulders sit on top of ground devoid of vegetation. Humans appear almost miniature in scale against a swath of shadowy mountains. At first glance, it seems a perfect scene from an excursion on the Moon’s surface … except the people are in hiking gear, not spacesuits.

Iceland has served as a lunar stand-in for training NASA astronauts since the days of the Apollo missions, and this summer the Artemis II crew took its place in that long history. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, along with their backups, NASA astronaut Andre Douglas and CSA astronaut Jenni Gibbons, joined geology experts for field training on the Nordic island.

“Apollo astronauts said Iceland was one of the most lunar-like training locations that they went to in their training,” said Cindy Evans, Artemis geology training lead at NASA’s Johnson Space Center in Houston. “It has lunar-like planetary processes – in this case, volcanism. It has the landscape; it looks like the Moon. And it has the scale of features astronauts will both be observing and exploring on the Moon.”

Iceland’s geology, like the Moon’s, includes rocks called basalts and breccias. Basalts are dark, fine-grained, iron-rich rocks that form when volcanic magma cools and crystalizes quickly. In Iceland, basalt lavas form from volcanoes and deep fissures. On the Moon, basalts can form from both volcanoes and lava pooling in impact basins. Breccias are angular fragments of rock that are fused together to create new rocks. In Iceland, volcanic breccias are formed from explosive volcanic eruptions and on the Moon, impact breccias are formed from meteoroids impacting the lunar surface.

Apollo astronauts said Iceland was one of the most lunar-like training locations that they went to in their training.

Artemis Geology Training Lead

Along with exploring the geology of Iceland, the astronauts practiced navigation and expeditionary skills to prepare them for living and working together, and gave feedback to instructors, who used this as an opportunity to hone their instruction and identify sites for future Artemis crew training. They also put tools to the test, learning to use hammers, scoops, and chisels to collect rock samples.

“The tools we used during the Apollo missions haven’t changed that much for what we’re planning for the Artemis missions,” said Trevor Graff, exploration geologist and the hardware and testing lead on the Artemis science team at NASA Johnson. “Traditionally, a geologist goes out with just standard tool sets of things like rock hammers and scoops or shovels to sample the world around them, both on the surface and subsurface.”

The Artemis tools have a bit of a twist from traditional terrestrial geology tools, though. Engineers must take into consideration limited mass availability during launch, how easy it is to use a tool while wearing pressurized gloves, and how to ensure the pristine nature of the lunar samples is preserved for study back on Earth.

There’s really transformational science that we can learn by getting boots back on the Moon, getting samples back, and being able to do field geology with trained astronauts on the surface.

Exploration Geologist and Artemis II Science Officer

“There’s really transformational science that we can learn by getting boots back on the Moon, getting samples back, and being able to do field geology with trained astronauts on the surface,” said Angela Garcia, exploration geologist and an Artemis II science officer at NASA Johnson.

The Artemis II test flight will be NASA’s first mission with crew under Artemis and will pave the way to land the first woman, first person of color, and first international partner astronaut on the Moon on future missions. The crew will travel approximately 4,600 miles beyond the far side of the Moon. While the Artemis II astronauts will not land on the surface of the Moon, the geology fundamentals they develop during field training will be critical to meeting the science objectives of their mission.

These objectives include visually studying a list of surface features, such as craters, from orbit. Astronauts will snap photos of the features, and describe their color, reflectivity, and texture — details that can reveal their geologic history.

“Having humans hold the camera during a lunar pass and describe what they’re seeing in language that scientists can understand is a boon for science,” said Kelsey Young, lunar science lead for Artemis II and Artemis II science officer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “In large part, that’s what we’re training astronauts to do when we take them to these Moon-like environments on Earth.”

Hubble Examines a Spiral Star Factory This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 5668. ESA/Hubble & NASA, C. Kilpatrick

This NASA/ESA Hubble Space Telescope image features a spiral galaxy in the constellation Virgo named NGC 5668. It is relatively near to us at 90 million light-years from Earth and quite accessible for astronomers to study with both space- and ground-based telescopes. At first glance, it doesn’t seem like a remarkable galaxy. It is around 90,000 light-years across, similar in size and mass to our own Milky Way galaxy, and its nearly face-on orientation shows open spiral arms made of cloudy, irregular patches.

One noticeable difference between the Milky Way galaxy and NGC 5668 is that this galaxy is forming new stars 60% more quickly. Astronomers have identified two main drivers of star formation in NGC 5668. Firstly, this high-quality Hubble view reveals a bar at the galaxy’s center, though it might look more like a slight oval shape than a real bar. The bar appears to have affected the galaxy’s star formation rate, as central bars do in many spiral galaxies. Secondly, astronomers tracked high-velocity clouds of hydrogen gas moving vertically between the disk of the galaxy and the spherical, faint halo which surrounds it. These movements may be the result of strong stellar winds from hot, massive stars, that would contribute gas to new star-forming regions.

The enhanced star formation rate in NGC 5668 comes with a corresponding abundance of supernova explosions. Astronomers have spotted three in the galaxy, in 1952, 1954, and 2004. In this image, Hubble examined the surroundings of the Type II SN 2004G, seeking to study the kinds of stars that end their lives as this kind of supernova.

On Aug. 21, 2024, engineers and technicians deployed and tested NASA’s Europa Clipper giant solar arrays. Each array measures about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high.

Europa Clipper is scheduled to launch Oct. 10, 2024, on the first mission to conduct a detailed science investigation of Jupiter’s moon Europa. Scientists predict Europa has a salty ocean beneath its icy crust that could hold the building blocks necessary to sustain life.

The International Space Station is pictured from the SpaceX Crew Dragon Endeavour during a fly around.NASA

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are headed to the International Space Station for the agency’s SpaceX Crew-9 mission in September. Once on station, these crew members will support scientific investigations that include studies of blood clotting, effects of moisture on plants grown in space, and vision changes in astronauts.

Here are details on some of the work scheduled during the Crew-9 expedition:

Blood cell development in space

Megakaryocytes Orbiting in Outer Space and Near Earth (MeF1) investigates how environmental conditions affect the development and function of megakaryocytes and platelets. Megakaryocytes, large cells found in bone marrow, and platelets, pieces of these cells, play important roles in blood clotting and immune response.

“Understanding the development and function of megakaryocytes and platelets during long-duration spaceflight is crucial to safeguarding the health of astronauts,” said Hansjorg Schwertz, principal investigator, at the University of Utah. “Sending megakaryocyte cell cultures into space offers a unique opportunity to explore their intricate differentiation process. Microgravity also may impact other blood cells, so the insights we gain are likely to enhance our overall comprehension of how spaceflight influences blood cell production.”

Results could provide critical knowledge about the risks of changes in inflammation, immune responses, and clot formation in spaceflight and on the ground.

The Neutron Star Interior Composition Explorer (NICER) telescope on the exterior of the space station measures X-rays emitted by neutron stars and other cosmic objects to help answer questions about matter and gravity.

In May 2023, NICER developed a “light leak” that allows sunlight to interfere with daytime measurements. Special patches designed to cover some of the damage will be installed during a future spacewalk, returning the instrument to around-the-clock operation.

“This will be the fourth science observatory and first X-ray telescope in orbit to be repaired by astronauts,” said principal investigator Keith Gendreau at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “In just a year, we diagnosed the problem, designed and tested a solution, and delivered it for launch. The space station team — from managers and safety experts to engineers and astronauts — helped us make it happen. We’re looking forward to getting back to normal science operations.”

This view shows NICER’s 56 X-ray concentrators. Astronauts plan to cover some of them with special patches on a future spacewalk. NASA Vitamins for vision

Some astronauts experience vision changes, a condition called Spaceflight-Associated Neuro-ocular Syndrome. The B Complex investigation tests whether a daily B vitamin supplement can prevent or mitigate this problem and assesses how genetics may influence individual response.

“We still do not know exactly what causes this syndrome, and not everyone gets it,” said Sara Zwart, principal investigator, at the University of Texas Medical Branch, Houston. “It is likely many factors, and biological variations that make some astronauts more susceptible than others.”

One such variation could be related to a metabolic pathway that requires B vitamins to function properly. Inefficiencies in this pathway can affect the inner lining of blood vessels, resulting in leaks that may contribute to vision changes. Providing B vitamins known to affect blood vessel function positively could minimize issues in genetically at-risk astronauts.

“The concept of this study is based on 13 years of flight and ground research,” Zwart said. “We are excited to finally flight test a low-risk countermeasure that could mitigate the risk on future missions, including those to Mars.”

NASA astronaut Mark Vande Hei conducts a vision exam on the International Space StationNASA Watering the space garden

As people travel farther from Earth for longer, growing food becomes increasingly important. Scientists conducted many plant growth experiments on the space station using its Veggie hardware, including Veg-01B, which demonstrated that ‘Outredgeous’ red romaine lettuce is suitable for crop production in space.

Plant Habitat-07 uses this lettuce to examine how moisture conditions affect the nutritional quality and microbial safety of plants. The Advanced Plant Habitat controls humidity, temperature, air, light, and soil moisture, creating the precise conditions needed for the experiment.

Using a plant known to grow well in space removes a challenging variable from the equation, explained Chad Vanden Bosch, principal investigator at Redwire, and this lettuce also has been proven to be safe to consume when grown in space.

“For crews building a base on the Moon or Mars, tending to plants may be low on their list of responsibilities, so plant growth systems need to be automated,” Bosch said. “Such systems may not always provide the perfect growing conditions, though, so we need to know if plants grown in suboptimal conditions are safe to consume.”

John Campbell, a logistics engineer at NASA’s Marshall Space Flight Center, stands on NASA’s Pegasus barge July 15. NASA

How do you move NASA’s SLS (Space Launch System) rocket’s massive 212-foot-long core stage across the country? You do it with a 300-foot-long barge. However, NASA’s Pegasus barge isn’t just any barge. It’s a vessel with a history, and John Campbell, a logistics engineer for the agency based at NASA’s Marshall Space Flight Center in Huntsville, Alabama, is one of the few people who get to be a part of its legacy.

For Campbell, this journey is more than just a job – it’s a lifelong passion realized. “Ever since I was a boy, I’ve been fascinated by engineering,” he said. “But to be entrusted with managing NASA’s Pegasus barge, transporting history-making hardware for human spaceflight across state lines and waterways – is something I never imagined.”

NASA has used barges to ferry the large,and heavy hardware elements of its rockets since the Apollo Program. Replacing the agency’s Poseidon and Orion barges, Pegasus was originally crafted for the Space Shuttle Program and updated in recent years to help usher in the Artemis Generation and accommodate the mammoth dimensions of the SLS core stage. The barge plays a big role in NASA’s logistical operations, navigating rivers and coastal waters across the Southeast, and has transported key structural test hardware for SLS in recent years.

Campbell grew up in Muscle Shoals, Alabama. After graduating from the University of Alabama with a degree in mechanical engineering, he ventured south to Panama City, Florida, where he spent a few years with a heating, ventilation, and air conditioning consulting team. Looking for an opportunity to move home, he applied for and landed a contractor position with NASA and soon moved to his current civil service role.

With 17 years under his belt, Campbell has many fond memories during his time with the agency. One standout moment was witnessing the space shuttle stacked in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. But it’s not all about rockets and launch pads for Campbell. When he isn’t in his office making sure  Pegasus has everything it needs for its next trip out, he is on the water accompanying important pieces of hardware to their next destinations. With eight trips on Pegasus under his belt, the journey never gets old.

“There is something peaceful when you look out and it’s just you, the water, one or two other boats, and wildlife,” Campbell said. “On one trip we had a pod of at least 20 dolphins surrounding us. You get to see all kinds of cool wildlife and scenery.” From cherishing special moments like this to ensuring the success of each journey, Campbell recognizes the vital role he plays in the agency’s goals to travel back to the Moon and beyond and does not take his responsibility lightly.

“To be a part of the Artemis campaign and the future of space is just cool. I was there when the barge underwent its transformation to accommodate the colossal core stage, and in that moment, I realized I was witnessing history unfold. Though I couldn’t be present at the launch of Artemis I, watching it on TV was an emotional experience. To see something you’ve been a part of, something you’ve watched evolve from mere components to a giant spacecraft hurtling into space – it’s a feeling beyond words.”

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

During its 61st close flyby of Jupiter on May 12, 2024, NASA’s Juno spacecraft captured this color-enhanced view of the giant planet’s northern hemisphere. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists as a folded filamentary region. In these regions, the zonal jets that create the familiar banded patterns in Jupiter’s clouds break down, leading to turbulent patterns and cloud structures that rapidly evolve over the course of only a few days.

Citizen scientist Gary Eason made this image using raw data from the JunoCam instrument, applying digital processing techniques to enhance color and clarity.

At the time the raw image was taken, the Juno spacecraft was about 18,000 miles (29,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 68 degrees north of the equator.

On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin landed on the Moon in the lunar module “Eagle.” Afterward, Aldrin posed for this photo, taken by Armstrong, beside the United States flag.

The Apollo 11 mission’s main goal was to perform a crewed lunar landing and return to Earth. The crew also conducted scientific exploration of the Moon’s surface and deployed a television camera to transmit signals to Earth. Armstrong and Aldrin spent 21 hours and 36 minutes on the Moon. They explored the surface, took extensive photographs of the lunar terrain and each other, and collected lunar surface samples.

The two moonwalkers left behind commemorative medallions bearing the names of the three Apollo 1 astronauts who lost their lives in a launch pad fire, and two cosmonauts who also died in accidents, on the lunar surface. Also left on the Moon were several tokens of world peace.

Preparations for Next Moonwalk Simulations Underway (and Underwater) The Arctic is captured in this 2010 visualization using data from NASA’s Aqua satellite. A new study quantifies how climate-related processes, including the melting of ice sheets and glaciers, are driving polar motion. Another study looks at how polar meltwater is speeding the lengthening of Earth’s day.NASA’s Scientific Visualization Studio

Researchers used more than 120 years of data to decipher how melting ice, dwindling groundwater, and rising seas are nudging the planet’s spin axis and lengthening days.

Days on Earth are growing slightly longer, and that change is accelerating. The reason is connected to the same mechanisms that also have caused the planet’s axis to meander by about 30 feet (10 meters) in the past 120 years. The findings come from two recent NASA-funded studies focused on how the climate-related redistribution of ice and water has affected Earth’s rotation.

This redistribution occurs when ice sheets and glaciers melt more than they grow from snowfall and when aquifers lose more groundwater than precipitation replenishes. These resulting shifts in mass cause the planet to wobble as it spins and its axis to shift location — a phenomenon called polar motion. They also cause Earth’s rotation to slow, measured by the lengthening of the day. Both have been recorded since 1900.

The animation, exaggerated for clarity, illustrates how Earth’s rotation wobbles as the location of its spin axis, shown in orange, moves away from its geographic axis, which is shown in blue and represents the imaginary line between the planet’s geographic North and South poles.NASA’s Scientific Visualization Studio

Analyzing polar motion across 12 decades, scientists attributed nearly all of the periodic oscillations in the axis’ position to changes in groundwater, ice sheets, glaciers, and sea levels. According to a paper published recently in Nature Geoscience, the mass variations during the 20th century mostly resulted from natural climate cycles.

The same researchers teamed on a subsequent study that focused on day length. They found that, since 2000, days have been getting longer by about 1.33 milliseconds per 100 years, a faster pace than at any point in the prior century. The cause: the accelerated melting of glaciers and the Antarctic and Greenland ice sheets due to human-caused greenhouse emissions. Their results were published July 15 in Proceedings of the National Academy of Sciences.

“The common thread between the two papers is that climate-related changes on Earth’s surface, whether human-caused or not, are strong drivers of the changes we’re seeing in the planet’s rotation,” said Surendra Adhikari, a co-author of both papers and a geophysicist at NASA’s Jet Propulsion Laboratory in Southern California.

The location of Earth’s spin axis moved about 30 feet (10 meters) between 1900 and 2023, as shown in this animation. A recent study found that about 90% of the periodic oscillations in polar motion could be explained by melting ice sheets and glaciers, diminishing groundwater, and sea level rise.NASA/JPL-Caltech Decades of Polar Motion

In the earliest days, scientists tracked polar motion by measuring the apparent movement of stars. They later switched to very long baseline interferometry, which analyzes radio signals from quasars, or satellite laser ranging, which points lasers at satellites.

Researchers have long surmised that polar motion results from a combination of processes in Earth’s interior and at the surface. Less clear was how much each process shifts the axis and what kind of effect each exerts — whether cyclical movements that repeat in periods from weeks to decades, or sustained drift over the course of centuries or millennia.

For their paper, researchers used machine-learning algorithms to dissect the 120-year record. They found that 90% of recurring fluctuations between 1900 and 2018 could be explained by changes in groundwater, ice sheets, glaciers, and sea level. The remainder mostly resulted from Earth’s interior dynamics, like the wobble from the tilt of the inner core with respect to the bulk of the planet.

The patterns of polar motion linked to surface mass shifts repeated a few times about every 25 years during the 20th century, suggesting to the researchers that they were largely due to natural climate variations. Past papers have drawn connections between more recent polar motion and human activities, including one authored by Adhikari that attributed a sudden eastward drift of the axis (starting around 2000) to faster melting of the Greenland and Antarctic ice sheets and groundwater depletion in Eurasia.

That research focused on the past two decades, during which groundwater and ice mass loss as well as sea level rise — all measured via satellites — have had strong connections to human-caused climate change.

“It’s true to a certain degree” that human activities factor into polar motion, said Mostafa Kiani Shahvandi, lead author of both papers and a doctoral student at the Swiss university ETH Zurich. “But there are natural modes in the climate system that have the main effect on polar motion oscillations.”

Longer Days

For the second paper, the authors used satellite observations of mass change from the GRACE mission (short for Gravity Recovery and Climate Experiment) and its follow-on GRACE-FO, as well as previous mass-balance studies that analyzed the contributions of changes in groundwater, ice sheets, and glaciers to sea level rise in the 20th century to reconstruct changes in the length of days due to those factors from 1900 to 2018.

Scientists have known through historical eclipse records that length of day has been growing for millennia. While almost imperceptible to humans, the lag must be accounted for because many modern technologies, including GPS, rely on precise timekeeping.

In recent decades, the faster melting of ice sheets has shifted mass from the poles toward the equatorial ocean. This flattening causes Earth to decelerate and the day to lengthen, similar to when an ice skater lowers and spreads their arms to slow a spin.

The authors noticed an uptick just after 2000 in how fast the day was lengthening, a change closely correlated with independent observations of the flattening. For the period from 2000 to 2018, the rate of length-of-day increase due to movement of ice and groundwater was 1.33 milliseconds per century — faster than at any period in the prior 100 years, when it varied from 0.3 to 1.0 milliseconds per century.

The lengthening due to ice and groundwater changes could decelerate by 2100 under a climate scenario of severely reduced emissions, the researchers note. (Even if emissions were to stop today, previously released gases — particularly carbon dioxide — would linger for decades longer.)

If emissions continue to rise, lengthening of day from climate change could reach as high as 2.62 milliseconds per century, overtaking the effect of the Moon’s pull on tides, which has been increasing Earth’s length of day by 2.4 milliseconds per century, on average. Called lunar tidal friction, the effect has been the primary cause of Earth’s day-length increase for billions for years.

“In barely 100 years, human beings have altered the climate system to such a degree that we’re seeing the impact on the very way the planet spins,” Adhikari said.

Five months later, Hague launched aboard Soyuz MS-12 and served as a flight engineer aboard the space station during Expeditions 59 and 60. Hague conducted three spacewalks to upgrade space station power systems and install a docking adapter for commercial spacecraft. As an active-duty colonel in the U.S. Space Force, Hague completed a developmental rotation at the Department of Defense in Washington, where he served as the USSF director of test and evaluation from 2020 to 2022. In August 2022, Hague resumed duties at NASA, working on the Boeing Starliner Program until this flight assignment. Follow @astrohague on X and @astrohauge on Instagram.

A veteran of three spaceflights aboard space shuttle Discovery, Wilson has spent 42 days in space. During her first mission, STS-121, in July 2006, she and her crewmates spent 13 days in orbit. Wilson served as the robotic arm operator for spacecraft inspection, the installation of the “Leonardo” Multi-Purpose Logistics Module, and spacewalk support. In October 2007, Wilson and her STS-120 crewmates delivered the Harmony module to the station and relocated a solar array. In April 2010, Wilson and her STS-131 crewmates completed another resupply mission to the orbiting complex, delivering a new ammonia tank for the station cooling system, new crew sleeping quarters, a window observation facility, and a freezer for experiments. During nearly 30 years with NASA, Wilson served as the integration branch chief for NASA’s Astronaut Office, focusing on International Space Station systems and payload operations. She also completed a nine-month detail as the acting chief of NASA’s Program and Project Integration Office at the agency’s Glenn Research Center in Cleveland. Follow @astro_stephanie on X.

This will be Gorbunov’s first trip to space and the station. Born in Zheleznogorsk, Kursk region, Russia, he studied engineering with qualifications in spacecraft and upper stages from the Moscow Aviation Institute. Gorbunov graduated from the military department with a specialty in operating and repairing aircraft, helicopters, and aircraft engines. Before being selected as a cosmonaut in 2018, he worked as an engineer for Rocket Space Corporation Energia and supported cargo spacecraft launches from the Baikonur Cosmodrome.

Hubble Studies a Potential Galactic Merger This NASA/ESA Hubble Space Telescope image captures the dwarf irregular galaxy NGC 5238. ESA/Hubble & NASA, F. Annibali

This NASA/ESA Hubble Space Telescope image features the dwarf irregular galaxy NGC 5238, located 14.5 million light-years from Earth in the constellation Canes Venatici. Its unexciting, blob-like appearance seems to resemble an oversized star cluster more than a classic image of a galaxy. Its lackluster appearance belies its complicated structure, which is the subject of a great deal of research. As the image reveals, Hubble is able to pick out the galaxy’s countless stars, as well as its associated globular clusters — glowing, bright spots both inside and around the galaxy swarmed by even more stars.

Astronomers theorize that NGC 5238 may have had a close encounter with another galaxy as recently as a billion years ago. NGC 5238’s distorted shape provides evidence for this interaction. As the two galaxies interacted, their gravity caused distortions in the distribution of stars in each galaxy. There’s no nearby galaxy which could have caused this disturbance, so astronomers think NGC 5238 devoured a smaller satellite galaxy. Astronomers look for traces of the consumed galaxy by closely examining the population of stars in NGC 5238, a task made for Hubble’s excellent resolution. One tell-tale sign of the smaller galaxy would be groups of stars with different properties from most of NGC 5238’s other stars, indicating they were originally formed in a separate galaxy. Another sign would be a burst of star formation that occurred abruptly at around the same time the two galaxies merged. The Hubble data used to create this image will help astronomers determine NGC 5238’s history.

Despite their small size and unremarkable appearance, it’s not unusual for dwarf galaxies like NGC 5238 to drive our understanding of galaxy formation and evolution. One main theory of galaxy evolution is that galaxies formed ‘bottom-up’ in a hierarchical fashion: star clusters and small galaxies were the first to form out of gas and dark matter. Over time, gravity gradually assembled these smaller objects into galaxy clusters and superclusters, which explains the shape of the largest structures we see in the universe today. A dwarf irregular galaxy like NGC 5238 merging with a smaller companion is just the type of event that might have started the process of galaxy assembly in the early universe. Hubble’s observations of tiny NGC 5238 may help test some of our most fundamental ideas of how the universe evolves!

Pegasus is currently transporting the SLS core stage from NASA’s Michoud Assembly Facility in New Orleans to NASA’s Kennedy Space Center in Florida, where it will be integrated and prepared for launch. During the Artemis II test flight, the core stage with its four RS-25 engines will provide more than 2 million pounds of thrust to help send the Artemis II crew around the Moon.

Pegasus, which was previously used to ferry space shuttle tanks, was modified and refurbished to ferry the SLS rocket’s massive core stage. At 212 feet in length and 27.6 feet in diameter, the Moon rocket stage is more than 50 feet longer than the space shuttle external tank.

NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.
