      In the unforgiving lunar environment, the possibility of an astronaut crewmember becoming incapacitated due to unforeseen circumstances (injury, medical emergency, or a mission-related accident) is a critical concern, starting with the upcoming Artemis III mission, where two astronaut crewmembers will explore the Lunar South Pole. The Moon’s surface is littered with rocks ranging from 0.15 to 20 meters in diameter and craters spanning 1 to 30 meters wide, making navigation challenging even under optimal conditions. The low gravity, unique lighting conditions, extreme temperatures, and availability of only one person to perform the rescue, further complicate any rescue efforts. Among the critical concerns is the safety of astronauts during Extravehicular Activities (EVAs). If an astronaut crewmember becomes incapacitated during a mission, the ability to return them safely and promptly to the human landing system is essential. A single crew member should be able to transport an incapacitated crew member distances up to 2 km and a slope of up to 20 degrees on the lunar terrain without the assistance of a lunar rover. This pressing issue opens the door for innovative solutions. We are looking for a cutting-edge design that is low in mass and easy to deploy, enabling one astronaut crewmember to safely transport their suited (343 kg (~755lb)) and fully incapacitated partner back to the human landing system. The solution must perform effectively in the Moon’s extreme South Pole environment and operate independently of a lunar rover. Your creativity and expertise could bridge this critical gap, enhancing the safety measures for future lunar explorers. By addressing this challenge, you have the opportunity to contribute to the next “giant leap” in human space exploration.

      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.”

      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.

      Bone cellsNASA Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms. 
      But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley.
      “Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’”
      O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks.
      jsc2022e083018 (10/26/2022) — A preflight image of beating cardiac spheroid composed of iPSC-derived cardiomyocytes (CMs), endothelial cells (ECs), and cardiac fibroblasts (CFs). These cells are incubated and put under the microscope in space as part of the Effect of Microgravity on Drug Responses Using Heart Organoids (Cardinal Heart 2.0) investigation. Image courtesy of Drs. Joseph Wu, Dilip Thomas and Xu Cao, Stanford Cardiovascular Institute “The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.”
      O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond.
      “It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.”
      During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth.
      As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen
      Malcolm o'malley
      Former NASA Intern
      “I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.”
      Artist conception of a future Artemis Base Camp on the lunar surface NASA When O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity. 
      O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.
