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.

Explorers on the Moon: Apollo 11 Landing

NASA

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.

NASA-Funded Studies Explain How Climate Is Changing Earth’s Rotation

6 min read

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.

NASA Awards Launch Excitement for STEM Learning Nationwide

3 Min Read NASA Awards Launch Excitement for STEM Learning Nationwide Southwest Girl Scout Council Leaders test out their “cereal box” pin-hole viewers to study the sun during educator training program.

NASA awards inspire the next generation of explorers by helping community institutions like museums, science centers, libraries, and other informal education institutions and their partners bring science, technology, engineering, and mathematics (STEM) content to their communities. NASA’s Next Generation STEM project has expanded the Teams Engaging Affiliated Museums and Informal Institutions (TEAM II) program to include a new tier of funding and provide even more opportunities to informal educational institutions across the country.

The new STEM Innovator tier will fund awards of approximately $250,000, the Community Anchor tier will continue to offer awards up to $50,000, and the highest award level will be designated the National Connector and fund initiatives up to $900,000. Fiscal year 2024 solicitations will target the Community Anchor and the new STEM Innovator award levels. Community Anchor and National Connector awards will be the focus for the fiscal year 2025 solicitation.

The TEAM II program was first expanded to include Community Anchors in 2022. Since then, the program has designated over 50 institutions across 29 states as NASA Community Anchors. These awards support proposals that strengthen the STEM impact of many community organizations, including:

5th-8th Graders from Whiting Village School join Flight Director Tyson as they embark on a Destination Mars Virtual Mission from their two-room schoolhouse in rural Maine.NASA

The Challenger Learning Center of Maine reached more than 960 K-8 students statewide through 58 virtual programs touching 27 mainland schools and four island schools, hosted a STEM community night for residents of rural Whiting, Maine, and held two virtual programs featuring NASA women engineers for girls across the state.

“NASA’s funding allowed Challenger Maine to provide this Mars mission experience for free to schools, no matter their size,” said Kirsten Hibbard, executive director of the Challenger Learning Center of Maine. “We’ve connected with new schools and become this resource, literally a community anchor of STEM, for these schools.”

Youth at the Standing Arrow Powwow on the Flathead Reservation experience remote sensing content with virtual reality.NASA

The University of Montana spectrUM Discovery Area engaged western Montana’s rural and tribal communities in understanding the role NASA and its partners play in sensing and responding to fire. SpectrUM developed the Montana Virtual Reality Fire Sensing Experience. Using ClassVR headsets, visitors learned about NOAA’s (National Oceanic and Atmospheric Administration) Joint Polar Satellite System satellites, JPSS-1 and JPSS-2, and how they are used to remotely sense the Earth.

SpectrUM collaborated with its community advisory group, SciNation on the Flathead Reservation, to incorporate fire and Earth science curricula developed by the Confederated Salish and Kootenai Tribes into their field trip and educational programs, impacting hundreds of students.

A student from Barksdale Air Force Base in Louisiana is excited to complete an activity in the “Aeronautics Museum in a Box” kit developed by NASA’s Aeronautics Research Mission Directorate; Community Anchor grantee Sci-Port Discovery Center in Shreveport, Louisiana; and Central Creativity, an education center in Laurel, Mississippi.NASA

Sci-Port Discovery Center Shreveport, Louisiana introduced middle and high school students to NASA aeronautics content through their Aeronautics Museum in a Box kits. The kits were developed in collaboration with NASA’s Aeronautics Research Mission Directorate, Sci-Port, and Central Creativity. The kits include fun, hands-on activities focusing on the parts of an airplane, principles of flight, airplane structure and materials, propulsion, future of flight, careers, and more. Students and families from underserved communities across Northwest Louisiana tested the kits and shared feedback with developers.

“Museum in a Box brought our participants to new heights beyond their imagination. They see themselves as teachers for their children, as a source of guidance for STEM careers instead of gangs,” said Dr. Heather Kleiner, director, Northwest LaSTEM Innovation Center, Sci-Port Discovery Center.

U.S. informal education institutions interested in proposing for these awards are invited to attend an optional pre-proposal webinar Thursday, July 25, or Tuesday, August 13. Event times and connection details are available here.

Hubble Studies a Potential Galactic Merger

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!

From One Crew to Another: Artemis II Astronauts Meet NASA Barge Crew

Members of the Artemis II crew met with the crew of NASA’s Pegasus barge prior to their departure to deliver the core stage of NASA’s SLS (Space Launch System) rocket to the Space Coast.

NASA astronaut and pilot of the Artemis II mission Victor Glover met the crew July 15.

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.
