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.”

On Sept. 20, 2024, four students experienced the wonder of space exploration at NASA’s Johnson Space Center in Houston, taking part in an international competition that brought their work to life aboard the International Space Station.
Now in its fifth year, the Kibo Robot Programming Challenge (Kibo-RPC) continues to push the boundaries of robotics, bringing together the world’s brightest young minds for a real-world test of programming, problem-solving, and innovation.
The Kibo Robot Programming Challenge (Kibo-RPC) students tour the Gateway Habitation and Logistics Outpost module at NASA’s Johnson Space Center in Houston.NASA/Helen Arase Vargas The stakes reached new heights in this year’s competition, with 661 teams totaling 2,788 students from 35 countries and regions competing to program robots aboard the orbiting laboratory. Organized by the Japan Aerospace Exploration Agency in collaboration with the United Nations Office for Outer Space Affairs, the challenge provided a unique platform for students to test their skills on a global stage.
Meet Team Salcedo
Representing the U.S., Team Salcedo is composed of four talented students: Aaron Kantsevoy, Gabriel Ashkenazi, Justin Bonner, and Lucas Paschke. Each member brought a unique skill set and perspective, contributing to the team’s well-rounded approach to the challenge.
From left to right are Kibo-RPC students Gabriel Ashkenazi, Lucas Paschke, Aaron Kantsevoy, and Justin Bonner. NASA/Helen Arase Vargas The team was named in honor of Dr. Alvaro Salcedo, a robotics teacher and competitive robotics coach who had a significant impact on Kantsevoy and Bonner during high school. Dr. Salcedo played a crucial role in shaping their interests and aspirations in science, technology, engineering, and mathematics (STEM), inspiring them to pursue careers in these fields.
Kantsevoy, a computer science major at Georgia Institute of Technology, or Georgia Tech, led the team with three years of Kibo-RPC experience and a deep interest in robotics and space-based agriculture. Bonner, a second-year student at the University of Miami, is pursuing a triple major in computer science, artificial intelligence, and mathematics. Known for his quick problem-solving, he played a key role as a strategist and computer vision expert. Paschke, a first-time participant and computer science student at Georgia Tech, focused on intelligence systems and architecture, and brought fresh insights to the table. Ashkenazi, also studying computer science at Georgia Tech, specialized in computer vision and DevOps, adding depth to the team’s technical capabilities.
AstroBee Takes Flight
The 2024 competition tasked students with programming AstroBee, a free-flying robot aboard the station, to navigate a complex course while capturing images scattered across the orbital outpost. For Team Salcedo, the challenge reached its peak as their code was tested live on the space station.

Watching AstroBee in action aboard the space station offered a rare glimpse of the direct impact of their programming skills and added a layer of excitement that pushed them to fine-tune their approach.
Overcoming Challenges in Real Time
Navigating AstroBee through the orbital outpost presented a set of unique challenges. The team had to ensure the robot could identify and target images scattered throughout the station with precision while minimizing the time spent between locations.
The Kibo-RPC students watch in real time as the free-flying robot Astrobee performs maneuvers aboard the International Space Station, executing tasks based on their input to test its capabilities. NASA/Helen Arase Vargas Using quaternions for smooth rotation in 3D space, they fine-tuned AstroBee’s movements to adjust camera angles and capture images from difficult positions without succumbing to the limitations of gimbal lock. Multithreading allowed the robot to simultaneously process images and move to the next target, optimizing the use of time in the fast-paced environment.
The Power of Teamwork and Mentorship
Working across different locations and time zones, Team Salcedo established a structured communication system to ensure seamless collaboration. Understanding each team member’s workflow and adjusting expectations accordingly helped them maintain efficiency, even when setbacks occurred.
Team Salcedo tour the Space Vehicle Mockup Facility with their NASA mentors (from top left to right) Education Coordinator Kaylie Mims, International Space Station Research Portfolio Manager Jorge Sotomayer, and Kibo-RPC Activity Manager Jamie Semple. NASA/Helen Arase Vargas Mentorship was crucial to their success, with the team crediting several advisors and educators for their guidance. Kantsevoy acknowledged his first STEM mentor, Casey Kleiman, who sparked his passion for robotics in middle school.
The team expressed gratitude to their Johnson mentors, including NASA Program Specialist Jamie Semple, Education Coordinator Kaylie Mims, and International Space Station Research Portfolio Manager Jorge Sotomayer, for guiding them through the program’s processes and providing support throughout the competition.
They also thanked NASA’s Office of STEM Engagement for offering the opportunity to present their project to Johnson employees.
“The challenge mirrors how the NASA workforce collaborates to achieve success in a highly technical environment. Team Salcedo has increased their knowledge and learned skills that they most likely would not have acquired individually,” said Semple. “As with all of our student design challenges, we hope this experience encourages the team to continue their work and studies to hopefully return to NASA in the future as full-time employees.”
Pushing the Boundaries of Innovation
The Kibo-RPC allowed Team Salcedo to experiment with new techniques, such as Slicing Aided Hyperinference—an approach that divides images into smaller tiles for more detailed analysis. Although this method showed promise in detecting smaller objects, it proved too time-consuming under the competition’s time constraints, teaching the students valuable lessons about prioritizing efficiency in engineering.
The Kibo-RPC students present their robotic programming challenge to the International Space Station Program. NASA/Bill Stafford For Team Salcedo, the programming challenge taught them the value of communication, the importance of learning from setbacks, and the rewards of perseverance. The thrill of seeing their code in action on the orbital outpost was a reminder of the limitless possibilities in robotics and space exploration.
Inspiring the Next Generation
With participants from diverse backgrounds coming together to compete on a global platform, the Kibo-RPC continues to be a proving ground for future innovators.
The challenge tested the technical abilities of students and fostered personal growth and collaboration, setting the stage for the next generation of robotics engineers and leaders.

As Team Salcedo looks ahead, they carry with them the skills, experiences, and inspiration needed to push the boundaries of human space exploration.
“With programs like Kibo-RPC, we are nurturing the next generation of explorers – the Artemis Generation,” said Sotomayer. “It’s not far-fetched to imagine that one of these students could eventually be walking on the Moon or Mars.”
The winners were announced virtually from Japan on Nov. 9, with Team Salcedo achieving sixth place.

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!

Researchers demonstrated the feasibility of 3D bioprinting a meniscus or knee cartilage tissue in microgravity. This successful result advances technology for bioprinting tissue to treat musculoskeletal injuries on long-term spaceflight or in extraterrestrial settings where resources and supply capacities are limited.
BFF Meniscus-2 evaluated using the BioFabrication Facility to 3D print knee cartilage tissue using bioinks and cells. The meniscus is the first engineered tissue of an anatomically relevant shape printed on the station. Manufactured human tissues have potential as alternatives to donor organs, which are in short supply. Bioprinting in microgravity overcomes some of the challenges present in Earth’s gravity, such as deformation or collapse of tissue structures.

These findings could help researchers develop treatments for neurodegenerative diseases on Earth and address potential adverse neurological effects of spaceflight.
Cosmic Brain Organoids examined growth and gene expression in 3D organoids created with neural stem cells from individuals with primary progressive multiple sclerosis and Parkinson’s disease. Results could improve understanding of these neurological diseases and support development of new treatments. Researchers plan additional studies on the underlying causes of the accelerated neuron maturation.

Jeanne Frances Loring, National Stem Cell Foundation Researchers demonstrated that induced pluripotent stem cells (iPSCs) can be processed in microgravity using off the-shelf cell culture materials. Using standard laboratory equipment and protocols could reduce costs and make space-based biomedical research accessible to a broader range of scientists and institutions.
Stellar Stem Cells Ax-2 evaluated how microgravity affects methods used to generate and grow stem cells into a variety of tissue types on the ground. iPSCs can give rise to any type of cell or tissue in the human body, and insight into processing in space could support their use in regenerative medicine and future large-scale biomanufacturing of cellular therapeutics in space.

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.
