Researchers have utilized infrared survey data to refine the asteroid’s size and surface brightness in support of the Nov. 1 encounter by NASA’s Lucy mission.

NASA’s Lucy mission will soon have its first asteroid encounter as the spacecraft travels through deep space en route to Jupiter’s orbit. But before the spacecraft passes 265 miles (425 kilometers) from the surface of the small asteroid Dinkinesh, researchers have used 13-year-old infrared data from NASA’s Wide-field Infrared Survey Explorer (WISE) to support the mission’s flyby. Their new study provides updated estimates of the asteroid’s size and albedo – a measurement of surface reflectivity – that could help scientists better understand the nature of some near-Earth objects.

Located between Mars and Jupiter, the main asteroid belt is home to most asteroids in our solar system, including Dinkinesh, which is following an orbit around the Sun that places it near Lucy’s path. The Lucy mission is using the Dinkinesh encounter as an opportunity to test systems and procedures that are designed to keep the asteroid within the science instruments’ fields of view as the spacecraft flies past at 10,000 mph (4.5 kilometers per second). This will help the team prepare for the mission’s primary objective: investigating the Jupiter Trojan asteroids, a population of primitive small bodies orbiting in tandem with Jupiter.

In the new study, published in the Astrophysical Journal Letters, University of Arizona researchers used observations made by the WISE spacecraft, which serendipitously scanned Dinkinesh in 2010 during its prime mission. Managed by NASA’s Jet Propulsion Laboratory in Southern California, WISE launched on Dec. 14, 2009, to create an all-sky infrared map of the universe.

Although the signal was weak in the exposures captured by WISE, the authors managed to identify 17 infrared observations of the region of sky where Dinkinesh’s signal could be seen. Then they used an algorithm to align and stack the images. The observations were made in March 2010 and represent 36.5 hours of observing time.

“Dinkinesh wasn’t initially detected by WISE, because the asteroid’s infrared signal was too weak for the software that was designed to find objects in a single exposure,” said Kiana De’Marius McFadden, a graduate student at the University of Arizona and lead author of the study. “But the asteroid’s dim infrared signal was still there, so our main challenge was to first find Dinkinesh and then to stack multiple exposures of the same region of sky to get its signal to emerge from the noise.”

Beyond WISE

Dinkinesh was discovered in 1999 – over a decade before WISE made the observations – and although its approximate size has been known, the new analysis refines not only its size, but also its albedo. The WISE observations suggest the asteroid has a diameter of about a half-mile (760 meters) and an albedo consistent with stony (S-type) asteroids.

Although WISE’s purpose wasn’t to detect asteroids, the spacecraft was sensitive to the infrared light (which is invisible to the naked eye) radiating from them as a result of sunlight heating their rocky surfaces. WISE had recorded about 190,000 asteroid observations by the end of its prime mission. In 2013, NASA reactivated WISE and renamed the mission Near-Earth Object Wide-field Survey Explorer (NEOWISE). Its purpose: to detect and track asteroids and comets that stray close to Earth’s orbit.

“Dinkinesh is the smallest main belt asteroid to be studied up-close and could provide valuable information about this type of object,” said the University of Arizona’s Amy Mainzer, a study co-author and the principal investigator for NEOWISE. “This population of main-belt asteroids overlap in size with the potentially hazardous near-Earth object population. Studying Dinkinesh could provide insights as to how these small main-belt asteroids form and where near-Earth asteroids come from.”

Targeting a late-2027 launch, NASA’s Near-Earth Object Surveyor (NEO Surveyor) will take over where NEOWISE leaves off. Scanning the sky in infrared wavelengths for hard-to-find asteroids and comets, NEO Surveyor could also utilize the same technique used to detect faint signals hiding in WISE observations, boosting the next-generation space telescope’s power. Mainzer is the principal investigator for NEO Surveyor.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Coastal locations, such as Drakes Bay on the Point Reyes peninsula in Northern California, are increasingly vulnerable to sea level rise.NOAA/NMFS/WCR/CCO The information will help people who live in coastal areas prepare for impacts caused by rising sea levels.
      Earth’s ocean is rising, disrupting livelihoods and infrastructure in coastal communities around the world. Agencies and organizations are working to prepare people as their world changes around them, and NASA information is helping these efforts.
      The agency’s global data is now available in the sea level section of the Earth Information Center. NASA developed the global sea level change website in collaboration with the U.S. Department of Defense, the World Bank, the U.S. Department of State, and the United Nations Development Programme.  
      The site includes information on projected sea level rise through the year 2150 for coastlines around the world, as well as estimates of how much flooding a coastal community or region can expect to see in the next 30 years. The projections come from data collected by NASA and its partners and from computer models of ice sheets and the ocean, as well as the latest sea level assessment from the Intergovernmental Panel on Climate Change, and other sources.
      “NASA innovates for the benefit of humanity. Our cutting-edge instruments and data-driven information tools help communities and organizations respond to natural hazards and extreme weather, and inform critical coastal infrastructure planning decisions,” said Karen St. Germain, director of the Earth science division at NASA Headquarters in Washington.
      Information to Action
      International organizations such as the World Bank will use the data from the global sea level change site for tasks including the creation of Climate Risk Profiles for countries especially vulnerable to sea level rise.
      The Defense Department will continue to incorporate sea level rise data into its plans to anticipate and respond to hazards posed to its facilities by the effects of rising oceans. Similarly, the State Department uses the information for activities ranging from disaster preparedness to long-term adaptation planning to supporting partners around the world in related efforts.
      “We are at a moment of truth in our fight against the climate crisis. The science is unequivocal and must serve as the bedrock upon which decision-making is built. With many communities around the world already facing severe impacts from sea-level rise, this new resource provides a vital tool to help them protect lives and livelihoods. It also illustrates what is at stake between a 1.5-degree-Celsius world and a current-policies trajectory for all coastal communities worldwide,” said Assistant Secretary-General Selwin Hart, special adviser to the United Nations secretary-general on climate action and just transition.
      Rising Faster
      NASA-led data analyses have revealed that between 1970 and 2023, 96% of countries with coastlines have experienced sea level rise. The rate of that global rise has also accelerated, more than doubling from 0.08 inches (0.21 centimeters) per year in 1993 to about 0.18 inches (0.45 centimeters) per year in 2023.
      As the rate of sea level rise increases, millions of people could face the related effects sooner than previously projected, including larger storm surges, more saltwater intrusion into groundwater, and additional high-tide flood days — also known as nuisance floods or sunny day floods.
      “This new platform shows the timing of future floods and the magnitude of rising waters in all coastal countries worldwide, connecting science and physics to impacts on people’s livelihoods and safety,” said Nadya Vinogradova Shiffer, director of the ocean physics program at NASA Headquarters in Washington.
      Data released earlier this year found that Pacific Island nations will experience at least 6 inches (15 centimeters) of sea level rise in the next 30 years. The number of high-tide flood days will increase by an order of magnitude for nearly all Pacific Island nations by the 2050s.
      “The data is clear: Sea levels are rising around the world, and they’re rising faster and faster,” said Ben Hamlington, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California and head of the agency’s sea level change science team. “Having the best information to make decisions about how to plan for rising seas is more crucial than ever.”

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Note: The following article is part of a series highlighting propulsion testing at NASA’s Stennis Space Center. To access the entire series, please visit: https://www.nasa.gov/feature/propulsion-powering-space-dreams/.
      Crews at NASA’s Stennis Space Center work Jan. 21-22, 2020, to install the first flight core stage of NASA’s powerful SLS (Space Launch System) rocket on the B-2 side of the Thad Cochran Test Stand for a Green Run test series. Operations required crews to lift the massive core stage from a horizontal position into a vertical orientation, a procedure known as “break over.” Once the stage was oriented in a horizontal position on the night of Jan. 21, crews tied it in place to await favorable wind conditions. The following morning, crews began the process of raising, positioning, and securing the stage on the stand. NASA/Stennis The future is now at NASA’s Stennis Space Center near Bay St. Louis, Mississippi – at least when it comes to helping power the next great era of human space exploration.  
      NASA Stennis is contributing directly to the agency’s effort to land the first woman, the first person of color, and its first international partner astronaut on the Moon – for the benefit of all humanity. Work at the nation’s largest – and premier – propulsion test site will help power SLS (Space Launch System) rockets on future Artemis missions to enable long-term lunar exploration and prepare for the next giant leap of sending the first astronauts to Mars.  
      “We play a critical role to ensure the safety of astronauts on future Artemis missions,” NASA Stennis Space Center Director John Bailey said. “Our dedicated workforce is excited and proud to be part of NASA’s return to the Moon.”  
      NASA Stennis achieved an RS-25 testing milestone in April at the Fred Haise Test Stand. Completion of the successful RS-25 certification series provided critical data for L3Harris (formerly known as Aerojet Rocketdyne) to produce new RS-25 engines, using modern processes and manufacturing techniques. The engines will help power SLS rockets beginning with Artemis V.   
      The first four Artemis missions are using modified space shuttle main engines also tested at NASA Stennis. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket to produce more than 8.8 million pounds of total combined thrust at liftoff.   
      NASA’s powerful SLS rocket is the only rocket that can send the Orion spacecraft, astronauts, and cargo to the Moon on a single mission.   
      Following key test infrastructure upgrades near the Fred Haise Test Stand, NASA Stennis will be ready for more RS-25 engine testing. NASA has awarded L3Harris contracts to provide 24 new engines, supporting SLS launches for Artemis V through Artemis IX.  
      “Every RS-25 engine that launches Artemis to space will be tested at NASA Stennis,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate. “We take pride in helping to power this nation’s human space exploration program. We also take great care in testing these engines because they are launching astronauts to space. We always have safety in mind.” 
      NASA’s Stennis Space Center conducts a successful hot fire of the first flight core stage of NASA’s powerful SLS (Space Launch System) rocket on the B-2 side of the Thad Cochran Test Stand on March 18, 2021. NASA employees, as well as NASA astronauts Jessica Meir and Zena Cardman, watched the milestone moment. The hot fire of more than eight minutes marked the culmination of a Green Run series of tests on the stage and its integrated systems.  NASA/Stennis In addition to RS-25 testing, preparations are ongoing at the Thad Cochran Test Stand (B-2) for future testing of the agency’s new exploration upper stage. The more powerful SLS second stage, which will send astronauts and cargo to deep space aboard the Orion spacecraft, is being built at NASA’s Michoud Assembly Facility in New Orleans.   
      Before its first flight, the NASA Stennis test team will conduct a series of Green Run tests on the new stage’s integrated systems to demonstrate it is ready to fly. Crews completed installation of a key component for testing the upper stage in October. The lift and installation of the 103-ton interstage simulator component, measuring 31 feet in diameter and 33 feet tall, provided crews best practices for moving and handling the actual flight hardware when it arrives to NASA Stennis.   
      The exploration upper stage Green Run test series will culminate with a hot fire of the stage’s four RL10 engines, made by L3Harris, the lead SLS engines contractor.  
      “All of Mississippi shares in our return to the Moon with the next great era of human space exploration going through NASA Stennis,” Bailey said. “Together, we can be proud of the state’s contributions to NASA’s great mission.”

      Name: Dr. Inia Soto Ramos
      Title and Formal Job Classification: Associate Research Scientist
      Organization: Ocean Ecology Laboratory (Code 616) via Morgan State University and GESTAR II cooperative agreement
      Dr. Inia Soto Ramos is an associate research scientist with NASA’s PACE — the Plankton, Aerosol, Cloud, ocean Ecosystem mission — at the agency’s Goddard Space Flight Center in Greenbelt, Md.Photo courtesy of Inia Soto Ramos What do you do and what is most interesting about your role here at Goddard?
      I am currently co-leading the validation efforts for PACE, NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem mission. I am also part of NASA’s SeaBASS (SeaWiFS Bio-optical Archive and Storage System) team, which is responsible for archiving, distributing, and managing field data used for validation and development of satellite ocean color data products. It has been exciting to be a part of a satellite mission, to see it being built, tested and launched. And now, be able to validate the data and in the near future, use the data to do science.
      What is your educational background?
      I graduated with a bachelor’s degree in biology from The University of Puerto Rico, Mayagüez Campus, and I have a master’s and Ph.D. in Biological Oceanography from the University of South Florida.
      How did you get your foot in the door at NASA?
      While I was a student at the University of Puerto Rico, I saw a flyer for a program called PaSCoR (Partnership for Spatial and Computational Research). It was a partnership between universities, NASA and other institutions with the intent to train students in remote sensing and Geographical Information Systems. Although, this program was targeted mainly for engineers, I decided to apply. That took me to the first remote sensing classes I had taken. That’s how I started learning that you can study the ocean from space. I had no idea that could be done. That program planted the curiosity about satellite oceanography and gave me the tools to go into graduate school in that field.
      How did you first gain exposure to oceanography and diving?
      I am from Puerto Rico and grew up all the way in the mountains. There wasn’t much of a connection to the ocean for me, only a few trips to the beach. I remember my dad taking me to a small beach called La Poza del Obispo in Arecibo and he held me while I used a small snorkel underwater. That was the first connection I had with marine life. I started diving sometime when I was about 18 years old, and I remember saying, “This is the most amazing thing ever,” and that’s when I decided I needed to pursue a life in that field.
      What interested you in phytoplankton as a specialty?
      Initially, I was curious about harmful algal blooms in the West Florida Shelf, which I studied when I moved to Florida to do my grad studies. I learned that the blooms can produce neurotoxins, and those can affect humans in different ways. So, if you have asthma, they can make you feel worse. I remember developing asthma that night after going to the beach and having go to the ER. I didn’t see the connection at the time until I learned about these events and how toxins can get in the air. It felt like something important that I could study to help people or do something that’s meaningful. It’s amazing that we can see something so tiny from space and study them.
      How does your identity, being a Latina, show up at NASA?
      This is kind of a dream come true. It is so amazing to be able to fulfill that dream. I came from a small town. There appeared to me no chances to come all the way to NASA. So, having this opportunity is exciting, and bringing it back to my community and saying, “Hey, anyone can actually do it.” One of the advantages is that you speak a different language, so you can make connections with different countries.
      What do you look forward to in the future? What are some of your goals?
       I would love to keep growing in my field. As a mother, sometimes is hard to visualize where I want to be in the future, so I find it best to focus on the present. My priority right now is my family, however in the future I would love to engage in a job in which I can transfer my knowledge and love to the oceans to future generations; and be more involved in the community.
      When you think of your village and growing up in Puerto Rico, what is a memory you have that makes you smile?
      I still remember going to collect coffee with my mom and dad. My dad had a small basket for me that I would fill with only the most beautiful red grains of coffee. I was around 5 years old, and I remember the toys that my mom would take, and they’d settle me under the coffee trees. I still go to Puerto Rico, and I am fascinated when I see the coffee trees; it reminds me of my childhood.
      What advice would you give to other little girls who might not think NASA is a dream they can achieve?
      I was the little girl with the dream of being a scientist at NASA, and then I was a teenager, an adult, and a mother, all with the same dream! It took me several decades and many life stages to get here. Many times, along my path, I thought of giving up. Others, I thought I was completely off track and I would never fulfill my dream. I had limited resources while growing up. There were no fancy swimming or piano classes, but I had amazing teachers and mentors who guided me along the way. So, no matter how young or old you are, you can still fulfill that dream. The key to success is to know where you want to go, surround yourself with people that believe in you, and if you fall, just shake it off and try again!

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s Voyager 2 captured this image of Uranus while flying by the ice giant in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery about the planet’s magnetosphere that now may be solved.NASA/JPL-Caltech NASA’s Voyager 2 flyby of Uranus decades ago shaped scientists’ understanding of the planet but also introduced unexplained oddities. A recent data dive has offered answers.
      When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first — and, so far, only — close glimpse of this strange, sideways-rotating outer planet. Alongside the discovery of new moons and rings, baffling new mysteries confronted scientists. The energized particles around the planet defied their understanding of how magnetic fields work to trap particle radiation, and Uranus earned a reputation as an outlier in our solar system.
      Now, new research analyzing the data collected during that flyby 38 years ago has found that the source of that particular mystery is a cosmic coincidence: It turns out that in the days just before Voyager 2’s flyby, the planet had been affected by an unusual kind of space weather that squashed the planet’s magnetic field, dramatically compressing Uranus’ magnetosphere.
      “If Voyager 2 had arrived just a few days earlier, it would have observed a completely different magnetosphere at Uranus,” said Jamie Jasinski of NASA’s Jet Propulsion Laboratory in Southern California and lead author of the new work published in Nature Astronomy. “The spacecraft saw Uranus in conditions that only occur about 4% of the time.”
      The first panel of this artist’s concept depicts how Uranus’s magnetosphere — its protective bubble — was behaving before the flyby of NASA’s Voyager 2. The second panel shows an unusual kind of solar weather was happening during the 1986 flyby, giving scientists a skewed view of the magnetosphere.NASA/JPL-Caltech Magnetospheres serve as protective bubbles around planets (including Earth) with magnetic cores and magnetic fields, shielding them from jets of ionized gas — or plasma — that stream out from the Sun in the solar wind. Learning more about how magnetospheres work is important for understanding our own planet, as well as those in seldom-visited corners of our solar system and beyond.
      That’s why scientists were eager to study Uranus’ magnetosphere, and what they saw in the Voyager 2 data in 1986 flummoxed them. Inside the planet’s magnetosphere were electron radiation belts with an intensity second only to Jupiter’s notoriously brutal radiation belts. But there was apparently no source of energized particles to feed those active belts; in fact, the rest of Uranus’ magnetosphere was almost devoid of plasma.
      The missing plasma also puzzled scientists because they knew that the five major Uranian moons in the magnetic bubble should have produced water ions, as icy moons around other outer planets do. They concluded that the moons must be inert with no ongoing activity.
      Solving the Mystery
      So why was no plasma observed, and what was happening to beef up the radiation belts? The new data analysis points to the solar wind. When plasma from the Sun pounded and compressed the magnetosphere, it likely drove plasma out of the system. The solar wind event also would have briefly intensified the dynamics of the magnetosphere, which would have fed the belts by injecting electrons into them.
      The findings could be good news for those five major moons of Uranus: Some of them might be geologically active after all. With an explanation for the temporarily missing plasma, researchers say it’s plausible that the moons actually may have been spewing ions into the surrounding bubble all along.
      Planetary scientists are focusing on bolstering their knowledge about the mysterious Uranus system, which the National Academies’ 2023 Planetary Science and Astrobiology Decadal Survey prioritized as a target for a future NASA mission.
      JPL’s Linda Spilker was among the Voyager 2 mission scientists glued to the images and other data that flowed in during the Uranus flyby in 1986. She remembers the anticipation and excitement of the event, which changed how scientists thought about the Uranian system.
      “The flyby was packed with surprises, and we were searching for an explanation of its unusual behavior. The magnetosphere Voyager 2 measured was only a snapshot in time,” said Spilker, who has returned to the iconic mission to lead its science team as project scientist. “This new work explains some of the apparent contradictions, and it will change our view of Uranus once again.”
      Voyager 2, now in interstellar space, is almost 13 billion miles (21 billion kilometers) from Earth.
