Earth planning date: Wednesday, May 22, 2024
One of the biggest challenges that comes with operating a rover on another planet is that we don’t always know exactly what we’re going to have in front of us when we park after driving. The science teams and our rover planners (who actually plan out the drives) do their best of what we have available, consisting of a combination of high-resolution imagery from the HiRISE camera onboard the Mars Reconnaissance Orbiter and images from Curiosity looking off in our planned drive direction.
Ultimately though, we don’t know what we’re going to be dealing with on any given planning day until we actually get there. Sometimes that’s because the drive “faults” and ends early, something that happens when driving over rocky or sandy terrain that causes the rover’s mobility systems to exceed their maximum allowable limits. That wasn’t the case today, as the 30 metre drive further towards the Gediz Vallis channel crossing that we planned on Monday executed perfectly. Instead, our “workspace” (the area in front of the rover that is reachable by the arm) was not as exciting as we had anticipated, consisting mostly of sand and smaller rocks.
Consequently, it was decided to convert today from a “contact science” plan where we unstow the arm on the first sol for a lengthy list of activities before driving away on the second sol, to a “touch and go” plan where we mostly focus on remote sensing and a more limited list of contact science activities (the “touch”) and drive away on the first sol (the “go”). From the environmental science side, these kinds of major plan reorganizations can be a bit stressful as they often involve lots of last-minute shuffling around of our pre-planned activities, but the transition today was thankfully fairly straightforward.
The decision to convert the plan ended up being a good decision anyway, as we parked with our left front wheel on top of a pile of small rocks, which limited the kinds of arm activities we could safely perform regardless of how interesting the workspace was. Moving the drive from the second to the first sol also means that we’ll be able to get more useful data down to Earth before planning for the long weekend begins on Friday.
Despite the less interesting workspace (and setting aside the fact that calling any part of the surface of another planet “less interesting” feels a little crazy), we’re still fitting a decent amount of science into this plan. The first sol kicks off with our remote sensing, beginning with ChemCam LIBS on “Lake Catherine” and two ChemCam RMI mosaics, one on the Kukenán butte that’s filled up our eastern view for many months now and another on “Echo Ridge,” a feature near the rover that we’re currently driving towards in the hopes of understanding its origin. Mastcam then performs its documentation of the LIBS target and takes a couple of images of “Evelyn Lake” and “Emerson Lake,” two of the slightly larger rocks that lie just outside of the current workspace.
We wrap this remote sensing session up with some environmental science, including a Mastcam tau to monitor the amount of dust in the atmosphere, a dust devil movie, and Navcam monitoring of the dust and sand on the rover deck. Before we drive, we briefly unstow the arm to take some MAHLI observations of Lake Catherine. Curiosity finishes its first sol in this plan by driving away, followed by our standard suite of post-drive images to help us with planning on Friday, including another Navcam deck monitoring mosaic to see if the drive moved around any of the sand and dust.
Because we’ll be in a new location, the second sol of this plan is all untargeted remote sensing. ChemCam will use AEGIS to autonomously search for a LIBS target in our new location, then we’ll take a series of short Navcam movies to look for dust devils around the rover and a Navcam 3×1 line-of-sight mosaic to determine the amount of dust currently in the atmosphere within Gale. Shortly after noon, Curiosity will call it a day (or sol, really) and head back to sleep for the rest of this plan, occasionally waking up to phone home with the data it has gathered. As always, DAN, REMS, and RAD remain hard at work in the background, RAD particularly so given the high solar activity that has been seen recently.

Making Connections: Marshall Hosts Annual Jamboree, Poster Expo
By Celine Smith
Engineers, researchers, and scientists at NASA’s Marshall Space Flight Center had the opportunity to showcase their vast range of projects and learn about others at Marshall’s annual Science, Technology, and Engineering Jamboree and Poster Expo.

The jamboree took place May 16 in Activities Building 4316. Team members created and displayed more than 100 posters summarizing their projects at the center. From engineering easier ways for astronauts to take pictures in space to studying galaxies light years away, the projects represented Marshall’s diverse capabilities. The jamboree also included eight flash talks, which are brief speeches from team members about their research and experiments.
The idea to host a jamboree originated from flash talks presented during past holiday luncheons at the National Space Science Technology Center (NSSTC) at the University of Alabama in Huntsville.
“Scientists were only allowed to speak about their discoveries and research for two minutes and were limited to one slide,” said Tom Inman, lead organizer and assistant director of Marshall’s Science and Technology Office. A cowbell was rung if the speaker went over their time, which added to the fun.

The event became its own entity to bring together NSSTC and other Marshall technologists. With Marshall team members becoming more aware of all that’s happening at the center, they can better connect with each other, according to Inman. In addition, learning about existing work could aid another project or create an entirely new one.
“If we know what other people are working on it sparks more work and more innovation, while also building our portfolio and Marshall,” Inman said. “It’s an opportunity to see our colleagues and potentially collaborate.”
During the expo, engineers, researchers, and scientists stood alongside their poster, educating viewers and answering questions about their work. Food trucks were present right outside the building for the lunch. The event also was open to attendees from other government agencies at Redstone Arsenal. The jamboree attracted about 850 people.

Larry Leopard, Marshall’s associate director, technical, welcomed attendees to the event.
“Innovation thrives in an environment where connections are nurtured, ideas are shared, and collaboration flourishes,” Leopard said. “That’s why today’s event is so important. It provides us with a platform to come together, exchange ideas, and forge new connections that will drive us forward.”

“Once again, NASA has shown that with the world’s finest workforce, we can reach the stars,” said NASA Administrator Bill Nelson. “Through space exploration, advances in aviation, groundbreaking science, new technologies, and more, the team of wizards at NASA do what is hard to achieve what is great. That’s the pioneer spirit that makes NASA the best place to work in the federal government. With this ingenuity and passion, we will continue to innovate for the benefit of all and inspire the world.”
The agency’s workforce explored new frontiers in 2023, including shattering an American record for longest astronaut spaceflight, announcing the Artemis II crew, launching the Deep Space Optical Communications experiment, partnering on a sustainable flight demonstration later designated as X-66, and celebrating a year of science gathered from the agency’s James Webb Space Telescope. Feats beyond our atmosphere persisted with NASA’s OSIRIS-Rex (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) mission – the first U.S. mission to collect an asteroid sample. Insights from the asteroid data will further NASA’s studies on celestial objects, while the agency also continues its pursuit to return astronauts to the Moon as part of the Artemis campaign.
Along with being the 65th anniversary of the agency, 2023 brought new climate data with the launching of the U.S. Greenhouse Gas Center and Earth Information Center, new perspectives on Earth’s surface water through NASA’s SWOT (Surface Water and Ocean Topography) mission, and accrued air quality data from NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission.
“NASA has proven yet again that we have the most dedicated workforce in the federal government,” said Joseph Pelfrey, director of NASA’s Marshall Space Flight Center. “At Marshall and Michoud Assembly Facility, I am confident that our contributions to the agency’s missions have secured our place in this new era of space exploration.”
The Partnership for Public Service began to compile the Best Places to Work rankings in 2003 to analyze federal employee’s viewpoints of leadership, work-life balance, and other factors of their job. A formula is used to evaluate employee responses to a federal survey, dividing submissions into four groups: large, midsize, and small agencies, in addition to their subcomponents.
Mission Success is in Our Hands is a safety initiative collaboration between NASA’s Marshall Space Flight Center and Jacobs. As part of the initiative, eight Marshall team members are featured in testimonial banners placed around the center. This is the seventh in a Marshall Star series profiling team members featured in the testimonial banners. The Mission Success team also awards the Golden Eagle Award on a quarterly basis to Marshall and contractor personnel who are nominated by their peers or management. Candidates for this award have made significant, identifiable contributions that exceed normal job expectations to advance flight safety and mission assurance. Nominations for 2024 are open now online on Inside Marshall.

NASA’s Compact Infrared Cameras Enable New Science
A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth’s upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets.
The cameras use sensitive, high-resolution strained-layer superlattice sensors, initially developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, using IRAD, Internal Research and Development funding.
Their compact construction, low mass, and adaptability enable engineers like Tilak Hewagama to adapt them to the needs of a variety of sciences.
Goddard engineer Murzy Jhabvala holds the heart of his Compact Thermal Imager camera technology – a high-resolution, high-spectral range infrared sensor suitable for small satellites and missions to other solar-system objects.
“Attaching filters directly to the detector eliminates the substantial mass of traditional lens and filter systems,” Hewagama said. “This allows a low-mass instrument with a compact focal plane which can now be chilled for infrared detection using smaller, more efficient coolers. Smaller satellites and missions can benefit from their resolution and accuracy.”
Engineer Murzy Jhabvala led the initial sensor development at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as well as leading today’s filter integration efforts.
Jhabvala also led the Compact Thermal Imager experiment on the International Space Station that demonstrated how the new sensor technology could survive in space while proving a major success for Earth science. More than 15 million images captured in two infrared bands earned inventors, Jhabvala, and NASA Goddard colleagues Don Jennings and Compton Tucker an agency Invention of the Year award for 2021.
The Compact Thermal Imager captured unusually severe fires in Australia from its perch on the International Space Station in 2019 and 2020. With its high resolution, detected the shape and location of fire fronts and how far they were from settled areas — information critically important to first responders.

Data from the test provided detailed information about wildfires, better understanding of the vertical structure of Earth’s clouds and atmosphere, and captured an updraft caused by wind lifting off Earth’s land features called a gravity wave.
The groundbreaking infrared sensors use layers of repeating molecular structures to interact with individual photons, or units of light. The sensors resolve more wavelengths of infrared at a higher resolution: 260 feet (80 meters) per pixel from orbit compared to 1,000 to 3,000 feet (375 to 1,000 meters) possible with current thermal cameras.
Jhabvala and NASA’s Advanced Land Imaging Thermal IR Sensor (ALTIRS) team are developing a six-band version for this year’s LiDAR, Hyperspectral, & Thermal Imager (G-LiHT) airborne project. This first-of-its-kind camera will measure surface heat and enable pollution monitoring and fire observations at high frame rates, he said.
NASA Goddard Earth scientist Doug Morton leads an ESTO project developing a Compact Fire Imager for wildfire detection and prediction.
“We’re not going to see fewer fires, so we’re trying to understand how fires release energy over their life cycle,” Morton said. “This will help us better understand the new nature of fires in an increasingly flammable world.”
CFI will monitor both the hottest fires which release more greenhouse gases and cooler, smoldering coals and ashes which produce more carbon monoxide and airborne particles like smoke and ash.
“Those are key ingredients when it comes to safety and understanding the greenhouse gases released by burning,” Morton said.
After they test the fire imager on airborne campaigns, Morton’s team envisions outfitting a fleet of 10 small satellites to provide global information about fires with more images per day.
Combined with next generation computer models, he said, “this information can help the forest service and other firefighting agencies prevent fires, improve safety for firefighters on the front lines, and protect the life and property of those living in the path of fires.”
Probing Clouds on Earth and Beyond
Outfitted with polarization filters, the sensor could measure how ice particles in Earth’s upper atmosphere clouds scatter and polarize light, NASA Goddard Earth scientist Dong Wu said.
This applications would complement NASA’s PACE — Plankton, Aerosol, Cloud, ocean Ecosystem — mission, Wu said, which revealed its first light images earlier this month. Both measure the polarization of light wave’s orientation in relation to the direction of travel from different parts of the infrared spectrum.
“The PACE polarimeters monitor visible and shortwave-infrared light,” he explained. “The mission will focus on aerosol and ocean color sciences from daytime observations. At mid- and long-infrared wavelengths, the new Infrared polarimeter would capture cloud and surface properties from both day and night observations.”
In another effort, Hewagama is working Jhabvala and Jennings to incorporate linear variable filters which provide even greater detail within the infrared spectrum. The filters reveal atmospheric molecules’ rotation and vibration as well as Earth’s surface composition.
That technology could also benefit missions to rocky planets, comets, and asteroids, planetary scientist Carrie Anderson said. She said they could identify ice and volatile compounds emitted in enormous plumes from Saturn’s moon Enceladus.
“They are essentially geysers of ice,” she said, “which of course are cold, but emit light within the new infrared sensor’s detection limits. Looking at the plumes against the backdrop of the Sun would allow us to identify their composition and vertical distribution very clearly.”

NASA, IBM Research to Release New AI Model for Weather, Climate
With the Privthi-weather-climate foundational model, researchers will be able to support many climate applications that can be used throughout the science community. These applications include detecting and improving models for severe weather patterns or natural disasters such as hurricanes. NASA’s Terra satellite acquired this image of Idalia in August 2023.

Working together, NASA and IBM Research have developed a new artificial intelligence model to support a variety of weather and climate applications. The new model – known as the Privthi-weather-climate foundational model – uses artificial intelligence (AI) in ways that could vastly improve the resolution we’ll be able to get, opening the door to better regional and local weather and climate models.
Foundational models are large-scale, base models which are trained on large, unlabeled datasets and can be fine-tuned for a variety of applications. The Privthi-weather-climate model is trained on a broad set of data – in this case NASA data from NASA’s Modern-Era Retrospective analysis for Research and Applications (MERRA-2)– and then makes use of AI learning abilities to apply patterns gleaned from the initial data across a broad range of additional scenarios.
“Advancing NASA’s Earth science for the benefit of humanity means delivering actionable science in ways that are useful to people, organizations, and communities. The rapid changes we’re witnessing on our home planet demand this strategy to meet the urgency of the moment,” said Karen St. Germain, director of the Earth Science Division of NASA’s Science Mission Directorate. “The NASA foundation model will help us produce a tool that people can use: weather, seasonal and climate projections to help inform decisions on how to prepare, respond and mitigate.”
With the Privthi-weather-climate model, researchers will be able to support many different climate applications that can be used throughout the science community. These applications include detecting and predicting severe weather patterns or natural disasters, creating targeted forecasts based on localized observations, improving spatial resolution on global climate simulations down to regional levels, and improving the representation of how physical processes are included in weather and climate models.
“These transformative AI models are reshaping data accessibility by significantly lowering the barrier of entry to using NASA’s scientific data,” said Kevin Murphy, NASA’s chief science data officer, Science Mission Directorate at NASA Headquarters. “Our open approach to sharing these models invites the global community to explore and harness the capabilities we’ve cultivated, ensuring that NASA’s investment enriches and benefits all.”
Privthi-weather-climate was developed through an open collaboration with IBM Research, Oak Ridge National Laboratory, and NASA, including the agency’s Interagency Implementation and Advanced Concepts Team (IMPACT) at Marshall Space Flight Center in Huntsville, Alabama.
Privthi-weather-climate can capture the complex dynamics of atmospheric physics even when there is missing information thanks to the flexibility of the model’s architecture. This foundational model for weather and climate can scale to both global and regional areas without compromising resolution.
“This model is part of our overall strategy to develop a family of AI foundation models to support NASA’s science mission goals,” said Rahul Ramachandran, who leads IMPACT at Marshall. “These models will augment our capabilities to draw insights from our vast archives of Earth observations.”
Privthi-weather-climate is part of a larger model family– the Privthi family– which includes models trained on NASA’s Harmonized LandSat and Sentinel-2 data. The latest model serves as an open collaboration in line with NASA’s open science principles to make all data accessible and usable by communities everywhere. It will be released later this year on Hugging Face, a machine learning and data science platform that helps users build, deploy, and train machine learning models.
“The development of the NASA foundation model for weather and climate is an important step towards the democratization of NASA’s science and observation mission,” said Tsendgar Lee, program manager for NASA’s Research and Analysis Weather Focus Area, High-End Computing Program, and Data for Operation and Assessment. “We will continue developing new technology for climate scenario analysis and decision making.”
Along with IMPACT and IBM Research, development of Privthi-weather-climate featured significant contributions from NASA’s Office of the Chief Science Data Officer, NASA’s Global Modeling and Assimilation Office at Goddard Space Flight Center, Oak Ridge National Laboratory, the University of Alabama in Huntsville, Colorado State University, and Stanford University.

A team of astronomers have studied 16 supermassive black holes that are firing powerful beams into space, to track where these beams, or jets, are pointing now and where they were aimed in the past, as reported in our latest press release. Using NASA’s Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National Radio Astronomical Observatory’s (NRAO) Very Large Baseline Array (VLBA), they found that some of the beams have changed directions by large amounts.
These two Chandra images show hot gas in the middle of the galaxy cluster Abell 478 (left) and the galaxy group NGC 5044 (right). The center of each image contains one of the sixteen black holes firing beams outwards. Each black hole is in the center of a galaxy embedded in the hot gas.
In the images below, labels and the radio images appear. Ellipses show a pair of cavities in the hot gas for Abell 478 (left) and ellipses show two pairs of cavities for NGC 5044 (right). These cavities were carved out by the beams millions of years ago, giving the directions of the beams in the past. An X shows the location of each supermassive black hole.

The VLBA images are shown as insets, which reveal where the beams are currently pointing, as seen from Earth. The radio images are both much smaller than the X-ray images. For Abell 478 the radio image is about 3% of the width of the Chandra image and for NGC 5044 the radio image is about 4% of the Chandra image’s width.
A comparison between the Chandra and VLBA images shows that the beams for Abell 478 changed direction by about 35 degrees and the beams for NGC 5044 changed direction by about 70 degrees.
Across the entire sample the researchers found that about a third of the 16 galaxies have beams that are pointing in completely different directions than they were before. Some have changed directions by nearly 90 degrees in some cases, and over timescales between one million years and a few tens of millions of years. Given that the black holes are of the order of 10 billion years old, this represents a relatively rapid change for these galaxies.

Black holes generate beams when material falls onto them via a spinning disk of matter and some of it then gets redirected outward. The direction of the beams from each of these giant black holes, which are likely spinning, is thought to align with the rotation axis of the black hole, meaning that the beams point along a line connecting the poles.
These beams are thought to be perpendicular to the disk. If material falls towards the black holes at a different angle that is not parallel to the disk, it could affect the direction of the black hole’s rotation axes, changing the direction of the beams.
Scientists think that beams from black holes and the cavities they carve out play an important role in how many stars form in their galaxies. The beams pump energy into the hot gas in and around the galaxy, preventing it from cooling down enough to form huge numbers of new stars. If the beams change directions by large amounts, they can tamp down star formation across much larger areas of the galaxy.

This image contains two X-ray images presented side by side, separated by a thin, gray line. On the left is an image of galaxy cluster Abell 478, and on the right is an image of galaxy group NGC 5044.
The X-ray image of Abell 478 resembles a gooey, blue substance that has been spilled on a black canvas. Most of the image is covered in this blue goo texture, which is hot gas in X-ray light, however there are cavities where no blue texture is present. At the center of the image is a bright, white region. Within the white region, too small to identify, exists Abell 478’s supermassive black hole.
The X-ray image of NGC 5044, on our right, is more pixelated than the image of Abell 478. It resembles blue television static or noise, that is present on a television when no transmission signal is detected. Most of the image is covered in this blue static, however there are cavities where no blue static is present. At the center of the image is a bright, white region. Within the white region, too small to identify, exists NGC 5044’s supermassive black hole.
