Preparations for Next Moonwalk Simulations Underway (and Underwater)

As students head back to school, teachers have a new tool that brings NASA satellite data down to their earthly classrooms.

For over 50 years of observing Earth, NASA’s satellites have collected petabytes of global science data (that’s millions and millions of gigabytes) – with terabytes more coming in by the day. Since 2004, the My NASA Data website has been developing ways for students and teachers of grades 3-12 to understand, and visualize NASA data, and to help incorporate those measurements into practical science lessons.

“We have three different types of lesson plans, some of which are student-facing and some are teacher-facing,” said Angie Rizzi, My NASA Data task lead, based at NASA’s Langley Research Center in Hampton, Virginia. “Teachers can download complete lesson plans or display a wide variety of Earth data. There are also lessons written for students to interact with directly.”

A key component of the My NASA Data site is the newly updated Earth System Data Explorer visualization tool, which allows users to access and download NASA Earth data. Educators can explore the data then create custom data tables, graphs, and plots to help students visualize the data. Students can create and investigate comparisons between  land surface temperatures, cloud cover, extreme heat, and a wide range of other characteristics for a specific location or region around the globe.

“The Earth System Data Explorer tool has a collection of science datasets organized by different spheres of the Earth system,” explained Desiray Wilson, My NASA Data scientific programmer. The program highlights six areas of study: atmosphere, biosphere, cryosphere, geosphere, hydrosphere, and Earth as a system. “The data goes as far back as the 1980s, and we are getting more daily datasets. It’s really good for looking at historical trends, regional trends, and patterns.”

My NASA Data had over one million site visits last year, with some of the most popular searches focusing on temperatures, precipitation, water vapor, and air quality.

Natalie Macke has been teaching for 20 years and is a science teacher at Pascack Hills High School in Montvale, New Jersey. Teachers like Macke help shape the lessons on the site through internships with the My NASA Data team. Teachers’ suggestions were also incorporated to enhance the visualization tool by adding new features that now allow users to swipe between visual layers of data and make side-by-side comparisons. Users can also now click on a location to display latitude and longitude and variable data streamlining the previous site which required manual input of latitude and longitude.

“The new visualization tool is very much a point-and-click layout like our students are used to in terms of just quickly selecting data they want to see,” said Macke. “Instantaneously, a map of the Earth comes up, or just the outline, and they can get the satellite view. So if they’re looking for a specific city, they can find the city on the map and quickly grab a dataset or multiple datasets and overlay it on the map to make visual comparisons.”

Even more valuable than creating visualizations for one specific lesson, elaborated Macke, is the opportunity My NASA Data provides for students to understand the importance of interpreting, verifying, and using datasets in their daily lives. This skill, she said, is invaluable, because it helps spread data literacy enabling users to look at data with a discriminating eye and learn to discern between assumptions and valid conclusions.

“Students can relate the data map to literally what’s happening outside their window, showing them how NASA Earth system satellite data relates to real life,” said Macke. “Creating a data literate public – meaning they understand the context and framework of the data they are working with and realizing the connection between the data and the real world – hopefully will intrigue them to continue to explore and learn about the Earth and start asking questions. That’s what got me into science when I was a little kid.”

      NASA Observes First Visible-light Auroras at Mars
      On March 15, 2024, near the peak of the current solar cycle, the Sun produced a solar flare and an accompanying coronal mass ejection (CME), a massive explosion of gas and magnetic energy that carries with it large amounts of solar energetic particles. This solar activity led to stunning auroras across the solar system, including at Mars, where NASA’s Perseverance Mars rover made history by detecting them for the first time from the surface of another planet.
      The first visible-light image of green aurora on Mars (left), taken by the Mastcam-Z instrument on NASA’s Perseverance Mars rover. On the right is a comparison image of the night sky of Mars without aurora but featuring the Martian moon Deimos. The moonlit Martian night sky, lit up mostly by Mars’ nearer and larger moon Phobos (outside the frame) has a reddish-brown hue due to the dust in the atmosphere, so when green auroral light is added, the sky takes on a green-yellow tone, as seen in the left image. NASA/JPL-Caltech/ASU/MSSS/SSI “This exciting discovery opens up new possibilities for auroral research and confirms that auroras could be visible to future astronauts on Mars’ surface.” said Elise Knutsen, a postdoctoral researcher at the University of Oslo in Norway and lead author of the Science Advances study, which reported the detection.
      Picking the right aurora
      On Earth, auroras form when solar particles interact with the global magnetic field, funneling them to the poles where they collide with atmospheric gases and emit light. The most common color, green, is caused by excited oxygen atoms emitting light at a wavelength of 557.7 nanometers. For years, scientists have theorized that green light auroras could also exist on Mars but suggested they would be much fainter and harder to capture than the green auroras we see on Earth.
      Due to the Red Planet’s lack of a global magnetic field, Mars has different types of auroras than those we have on Earth. One of these is solar energetic particle (SEP) auroras, which NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission discovered in 2014. These occur when super-energetic particles from the Sun hit the Martian atmosphere, causing a reaction that makes the atmosphere glow across the whole night sky.
      While MAVEN had observed SEP auroras in ultraviolet light from orbit, this phenomenon had never been observed in visible light from the ground. Since SEPs typically occur during solar storms, which increase during solar maximum, Knutsen and her team set their sights on capturing visible images and spectra of SEP aurora from Mars’ surface at the peak of the Sun’s current solar cycle.
      Coordinating the picture-perfect moment
      Through modeling, Knutsen and her team determined the optimal angle for the Perseverance rover’s SuperCam spectrometer and Mastcam-Z camera to successfully observe the SEP aurora in visible light. With this observation strategy in place, it all came down to the timing and understanding of CMEs.
      “The trick was to pick a good CME, one that would accelerate and inject many charged particles into Mars’ atmosphere,” said Knutsen.
      That is where the teams at NASA’s Moon to Mars (M2M) Space Weather Analysis Office and the Community Coordinated Modeling Center (CCMC), both located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, came in. The M2M team provides real-time analysis of solar eruptions to the CCMC for initiating simulations of CMEs to determine if they might impact current NASA missions. When the simulations suggest potential impacts, the team sends out an alert.
      At the University of California, Berkeley, space physicist Christina Lee received an alert from the M2M office about the March 15, 2024, CME. Lee, a member of the MAVEN mission team who serves as the space weather lead, determined there was a notable solar storm heading toward the Red Planet,which could arrive in a few days. She immediately issued the Mars Space Weather Alert Notification to currently operating Mars missions.
      “This allows the science teams of Perseverance and MAVEN to anticipate impacts of interplanetary CMEs and the associated SEPs,” said Lee.
      “When we saw the strength of this one,” Knutsen said, “we estimated it could trigger aurora bright enough for our instruments to detect.”
      A few days later, the CME impacted Mars, providing a lightshow for the rover to capture, showing the aurora to be nearly uniform across the sky at an emission wavelength of exactly 557.7 nm. To confirm the presence of SEPs during the aurora observation, the team looked to MAVEN’s SEP instrument, which was additionally corroborated by data from ESA’s (European Space Agency) Mars Express mission. Data from both missions confirmed that the rover team had managed to successfully catch a glimpse of the phenomenon in the very narrow time window available.
      “This was a fantastic example of cross-mission coordination. We all worked together quickly to facilitate this observation and are thrilled to have finally gotten a sneak peek of what astronauts will be able to see there some day,” said Shannon Curry, MAVEN principal investigator and research scientist at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder (CU Boulder).
      The future of aurora on Mars
      By coordinating the Perseverance observations with measurements from MAVEN’s SEP instrument, the teams could help each other determine that the observed 557.7 nm emission came from solar energetic particles. Since this is the same emission line as the green aurora on Earth, it is likely that future Martian astronauts would be able to see this type of aurora.
      “Perseverance’s observations of the visible-light aurora confirm a new way to study these phenomena that’s complementary to what we can observe with our Mars orbiters,” said Katie Stack Morgan, acting project scientist for Perseverance at NASA’s Jet Propulsion Laboratory in Southern California. “A better understanding of auroras and the conditions around Mars that lead to their formation are especially important as we prepare to send human explorers there safely.”
      On September 21, 2014, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft entered orbit around Mars. The mission has produced a wealth of data about how Mars’ atmosphere responds to the Sun and solar wind NASA/JPL-Caltech More About Perseverance and MAVEN
      The Mars 2020 Perseverance mission is part of NASA’s Mars Exploration Program portfolio and 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.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      New research suggests vast surface features on Venus called coronae continue to be shaped by tectonic processes. Observations of these features from NASA’s Magellan mission include, clockwise from top left, Artemis Corona, Quetzalpetlatl Corona, Bahet Corona, and Aine Corona.NASA/JPL-Caltech Using archival data from the mission, launched in 1989, researchers have uncovered new evidence that tectonic activity may be deforming the planet’s surface.
      Vast, quasi-circular features on Venus’ surface may reveal that the planet has ongoing tectonics, according to new research based on data gathered more than 30 years ago by NASA’s Magellan mission. On Earth, the planet’s surface is continually renewed by the constant shifting and recycling of massive sections of crust, called tectonic plates, that float atop a viscous interior. Venus doesn’t have tectonic plates, but its surface is still being deformed by molten material from below.
      Seeking to better understand the underlying processes driving these deformations, the researchers studied a type of feature called a corona. Ranging in size from dozens to hundreds of miles across, a corona is most often thought to be the location where a plume of hot, buoyant material from the planet’s mantle rises, pushing against the lithosphere above. (The lithosphere includes the planet’s crust and the uppermost part of its mantle.) These structures are usually oval, with a concentric fracture system surrounding them. Hundreds of coronae are known to exist on Venus.
      Published in the journal Science Advances, the new study details newly discovered signs of activity at or beneath the surface shaping many of Venus’ coronae, features that may also provide a unique window into Earth’s past. The researchers found the evidence of this tectonic activity within data from NASA’s Magellan mission, which orbited Venus in the 1990s and gathered the most detailed gravity and topography data on the planet currently available.
      “Coronae are not found on Earth today; however, they may have existed when our planet was young and before plate tectonics had been established,” said the study’s lead author, Gael Cascioli, assistant research scientist at the University of Maryland, Baltimore County, and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “By combining gravity and topography data, this research has provided a new and important insight into the possible subsurface processes currently shaping the surface of Venus.”
      This artist’s concept of the large Quetzalpetlatl Corona located in Venus’ southern hemisphere depicts active volcanism and a subduction zone, where the foreground crust plunges into the planet’s interior. A new study suggests coronae are the locations of several types of tectonic activity.NASA/JPL-Caltech/Peter Rubin As members of NASA’s forthcoming VERITAS (Venus Emissivity, Radio science, InSAR, Topography, and Spectroscopy) mission, Cascioli and his team are particularly interested in the high-resolution gravity data the spacecraft will provide. Study coauthor Erwan Mazarico, also at Goddard, will co-lead the VERITAS gravity experiment when the mission launches no earlier than 2031.
      Mystery Coronae
      Managed by NASA’s Jet Propulsion Laboratory in Southern California, Magellan used its radar system to see through Venus’ thick atmosphere and map the topography of its mountains and plains. Of the geological features the spacecraft mapped, coronae were perhaps the most enigmatic: It wasn’t clear how they formed. In the years since, scientists have found many coronae in locations where the planet’s lithosphere is thin and heat flow is high.
      “Coronae are abundant on Venus. They are very large features, and people have proposed different theories over the years as to how they formed,” said coauthor Anna Gülcher, Earth and planetary scientist at the University of Bern in Switzerland. “The most exciting thing for our study is that we can now say there are most likely various and ongoing active processes driving their formation. We believe these same processes may have occurred early in Earth’s history.”
      The researchers developed sophisticated 3D geodynamic models that demonstrate various formation scenarios for plume-induced coronae and compared them with the combined gravity and topography data from Magellan. The gravity data proved crucial in helping the researchers detect less dense, hot, and buoyant plumes under the surface — information that couldn’t be discerned from topography data alone. Of the 75 coronae studied, 52 appear to have buoyant mantle material beneath them that is likely driving tectonic processes.
      One key process is subduction: On Earth, it happens when the edge of one tectonic plate is driven beneath the adjacent plate. Friction between the plates can generate earthquakes, and as the old rocky material dives into the hot mantle, the rock melts and is recycled back to the surface via volcanic vents.
      These illustrations depict various types of tectonic activity thought to persist beneath Venus’ coronae. Lithospheric dripping and subduction are shown at top; below are and two scenarios where hot plume material rises and pushes against the lithosphere, potentially driving volcanism above it.Anna Gülcher, CC BY-NC On Venus, a different kind of subduction is thought to occur around the perimeter of some coronae. In this scenario, as a buoyant plume of hot rock in the mantle pushes upward into the lithosphere, surface material rises and spreads outward, colliding with surrounding surface material and pushing that material downward into the mantle.
      Another tectonic process known as lithospheric dripping could also be present, where dense accumulations of comparatively cool material sink from the lithosphere into the hot mantle. The researchers also identify several places where a third process may be taking place: A plume of molten rock beneath a thicker part of the lithosphere potentially drives volcanism above it.
      Deciphering Venus
      This work marks the latest instance of scientists returning to Magellan data to find that Venus exhibits geologic processes that are more Earth-like than originally thought. Recently, researchers were able to spot erupting volcanoes, including vast lava flows that vented from Maat Mons, Sif Mons, and Eistla Regio in radar images from the orbiter.
      While those images provided direct evidence of volcanic action, the authors of the new study will need sharper resolution to draw a complete picture about the tectonic processes driving corona formation. “The VERITAS gravity maps of Venus will boost the resolution by at least a factor of two to four, depending on location — a level of detail that could revolutionize our understanding of Venus’ geology and implications for early Earth,” said study coauthor Suzanne Smrekar, a planetary scientist at JPL and principal investigator for VERITAS.
      Managed by JPL, VERITAS will use a synthetic aperture radar to create 3D global maps and a near-infrared spectrometer to figure out what the surface of Venus is made of.  Using its radio tracking system, the spacecraft will also measure the planet’s gravitational field to determine the structure of Venus’ interior. All of these instruments will help pinpoint areas of activity on the surface.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      This artist’s concept shows the Moon’s hot interior and volcanism about 2 to 3 billion years ago. It is thought that volcanic activity on the lunar near side (the side facing Earth) helped create a landscape dominated by vast plains called mare, which are formed by molten rock that cooled and solidified. NASA/JPL-Caltech Analyzing gravity data collected by spacecraft orbiting other worlds reveals groundbreaking insights about planetary structures without having to land on the surface.
      Although the Moon and the asteroid Vesta are very different, two NASA studies use the same technique to reveal new details about the interiors of both.
      In the lunar study, published May 14 in the journal Nature, researchers developed a new gravity model of the Moon that includes tiny variations in the celestial body’s gravity during its elliptical orbit around Earth. These fluctuations cause the Moon to flex slightly due to Earth’s tidal force — a process called tidal deformation — which provides critical insights into the Moon’s deep internal structure.
      Using their model, the researchers produced the most detailed lunar gravitational map yet, providing future missions an improved way to calculate location and time on the Moon. They accomplished this by analyzing data on the motion of NASA’s GRAIL (Gravity Recovery and Interior Laboratory) mission, whose spacecraft, Ebb and Flow, orbited the Moon from Dec. 31, 2011, to Dec. 17, 2012.
      These views of the Moon’s near side, left, and far side were put together from observations made by NASA’s Lunar Reconnaissance Orbiter. NASA/JPL-Caltech In a second study, published in the journal Nature Astronomy on April 23, the researchers focused on Vesta, an object in the main asteroid belt between Mars and Jupiter. Using NASA’s Deep Space Network radiometric data and imaging data from the agency’s Dawn spacecraft, which orbited the asteroid from July 16, 2011, to Sept. 5, 2012, they found that instead of having distinct layers as expected, Vesta’s internal structure may be mostly uniform, with a very small iron core or no core at all.
      “Gravity is a unique and fundamental property of a planetary body that can be used to explore its deep interior,” said Park. “Our technique doesn’t need data from the surface; we just need to track the motion of the spacecraft very precisely to get a global view of what’s inside.”
      Lunar Asymmetry
      The lunar study looked at gravitational changes to the Moon’s near and far sides. While the near side is dominated by vast plains — known as mare — formed by molten rock that cooled and solidified billions of years ago, the far side is more rugged, with few plains.
      NASA’s Dawn mission obtained this image of the giant asteroid Vesta on July 24, 2011. The spacecraft spent 14 months orbiting the asteroid, capturing more than 30,000 images and fully mapping its surface. NASA/JPL-Caltech/UCLA/MPS/DLR/IDA Both studies were led by Ryan Park, supervisor of the Solar System Dynamics Group at NASA’s Jet Propulsion Laboratory in Southern California, and were years in the making due to their complexity. The team used NASA supercomputers to build a detailed map of how gravity varies across each body. From that, they could better understand what the Moon and Vesta are made of and how planetary bodies across the solar system formed.
      Some theories suggest intense volcanism on the near side likely caused these differences. That process would have caused radioactive, heat-generating elements to accumulate deep inside the near side’s mantle, and the new study offers the strongest evidence yet that this is likely the case.
      “We found that the Moon’s near side is flexing more than the far side, meaning there’s something fundamentally different about the internal structure of the Moon’s near side compared to its far side,” said Park. “When we first analyzed the data, we were so surprised by the result we didn’t believe it. So we ran the calculations many times to verify the findings. In all, this is a decade of work.”
      When comparing their results with other models, Park’s team found a small but greater-than-expected difference in how much the two hemispheres deform. The most likely explanation is that the near side has a warm mantle region, indicating the presence of heat-generating radioactive elements, which is evidence for volcanic activity that shaped the Moon’s near side 2 billion to 3 billion years ago.
      Vesta’s Evolution
      Park’s team applied a similar approach for their study that focused on Vesta’s rotational properties to learn more about its interior.  
      “Our technique is sensitive to any changes in the gravitational field of a body in space, whether that gravitational field changes over time, like the tidal flexing of the Moon, or through space, like a wobbling asteroid,” said Park. “Vesta wobbles as it spins, so we could measure its moment of inertia, a characteristic that is highly sensitive to the internal structure of the asteroid.”
      Changes in inertia can be seen when an ice skater spins with their arms held outward. As they pull their arms in, bringing more mass toward their center of gravity, their inertia decreases and their spin speeds up. By measuring Vesta’s inertia, scientists can gain a detailed understanding of the distribution of mass inside the asteroid: If its inertia is low, there would be a concentration of mass toward its center; if it’s high, the mass would be more evenly distributed.
      Some theories suggest that over a long period, Vesta gradually formed onion-like layers and a dense core. But the new inertia measurement from Park’s team suggests instead that Vesta is far more homogeneous, with its mass distributed evenly throughout and only a small core of dense material, or no core.
      Gravity slowly pulls the heaviest elements to a planet’s center over time, which is how Earth ended up with a dense core of liquid iron. While Vesta has long been considered a differentiated asteroid, a more homogenous structure would suggest that it may not have fully formed layers or may have formed from the debris of another planetary body after a massive impact.
      In 2016, Park used the same data types as the Vesta study to focus on Dawn’s second target, the dwarf planet Ceres, and results suggested a partially differentiated interior.
      Park and his team recently applied a similar technique to Jupiter’s volcanic moon Io, using data acquired by NASA’s Juno and Galileo spacecraft during their flybys of the Jovian satellite as well as from ground-based observations. By measuring how Io’s gravity changes as it orbits Jupiter, which exerts a powerful tidal force, they revealed that the fiery moon is unlikely to possess a global magma ocean.
      “Our technique isn’t restricted just to Io, Ceres, Vesta, or the Moon,” said Park. “There are many opportunities in the future to apply our technique for studying the interiors of intriguing planetary bodies throughout the solar system.”
