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)
Pacific Island nations such as Kiribati — a low-lying country in the southern Pacific Ocean — are preparing now for a future of higher sea levels.NASA Earth Observatory Climate change is rapidly reshaping a region of the world that’s home to millions of people.
In the next 30 years, Pacific Island nations such as Tuvalu, Kiribati, and Fiji will experience at least 8 inches (15 centimeters) of sea level rise, according to an analysis by NASA’s sea level change science team. This amount of rise will occur regardless of whether greenhouse gas emissions change in the coming years.
The sea level change team undertook the analysis of this region at the request of several Pacific Island nations, including Tuvalu and Kiribati, and in close coordination with the U.S. Department of State.
In addition to the overall analysis, the agency’s sea level team produced high-resolution maps showing which areas of different Pacific Island nations will be vulnerable to high-tide flooding — otherwise known as nuisance flooding or sunny day flooding — by the 2050s. Released on Sept. 23, the maps outline flooding potential in a range of emissions scenarios, from best-case to business-as-usual to worst-case.
“Sea level will continue to rise for centuries, causing more frequent flooding,” said Nadya Vinogradova Shiffer, who directs ocean physics programs for NASA’s Earth Science Division. “NASA’s new flood tool tells you what the potential increase in flooding frequency and severity look like in the next decades for the coastal communities of the Pacific Island nations.”
Team members, led by researchers at the University of Hawaii and in collaboration with scientists at the University of Colorado and Virginia Tech, started with flood maps of Kiribati, Tuvalu, Fiji, Nauru, and Niue. They plan to build high-resolution maps for other Pacific Island nations in the near future. The maps can assist Pacific Island nations in deciding where to focus mitigation efforts.
“Science and data can help the community of Tuvalu in relaying accurate sea level rise projections,” said Grace Malie, a youth leader from Tuvalu who is involved with the Rising Nations Initiative, a United Nations-supported program led by Pacific Island nations to help preserve their statehood and protect the rights and heritage of populations affected by climate change. “This will also help with early warning systems, which is something that our country is focusing on at the moment.”
Future Flooding
The analysis by the sea level change team also found that the number of high-tide flooding days in an average year will increase by an order of magnitude for nearly all Pacific Island nations by the 2050s. Portions of the NASA team’s analysis were included in a sea level rise report published by the United Nations in August 2024.
Areas of Tuvalu that currently see less than five high-tide flood days a year could average 25 flood days annually by the 2050s. Regions of Kiribati that see fewer than five flood days a year today will experience an average of 65 flood days annually by the 2050s.
“I am living the reality of climate change,” said Malie. “Everyone (in Tuvalu) lives by the coast or along the coastline, so everyone gets heavily affected by this.”
Flooding on island nations can come from the ocean inundating land during storms or during exceptionally high tides, called king tides. But it can also result when saltwater intrudes into underground areas and pushes the water table to the surface. “There are points on the island where we will see seawater bubbling from beneath the surface and heavily flooding the area,” Malie added.
Matter of Location
Sea level rise doesn’t occur uniformly around the world. A combination of global and local conditions, such as the topography of a coastline and how glacial meltwater is distributed in the ocean, affects the amount of rise a particular region will experience.
“We’re always focused on the differences in sea level rise from one region to another, but in the Pacific, the numbers are surprisingly consistent,” said Ben Hamlington, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California and the agency’s sea level change science team lead.
The impacts of 8 inches (15 centimeters) of sea level rise will vary from country to country. For instance, some nations could experience nuisance flooding several times a year at their airport, while others might face frequent neighborhood flooding equivalent to being inundated for nearly half the year.
Researchers would like to combine satellite data on ocean levels with ground-based measurements of sea levels at specific points, as well as with better land elevation information. “But there’s a real lack of on-the-ground data in these countries,” said Hamlington. The combination of space-based and ground-based measurements can yield more precise sea level rise projections and improved understanding of the impacts to countries in the Pacific.
“The future of the young people of Tuvalu is already at stake,” said Malie. “Climate change is more than an environmental crisis. It is about justice, survival for nations like Tuvalu, and global responsibility.”

A Hampton, Virginia, street is flooded by an exceptionally high tide in 2020. Rising seas could make high-tide flooding much more common in coastal communities around the world.Aileen Devlin/Virginia Sea Grant CC BY-ND 2.0 Designed to be user-friendly, the resource contains the latest sea level data, explainers, and other information from several U.S. agencies.
The U.S. Interagency Task Force on Sea Level Change launched the U.S. Sea Level Change website on Monday, Sept. 23. Designed to help communities prepare for rising seas, the site features the latest science on changing sea levels, details about the impact on the environment and coastal communities, and strategies to mitigate the consequences. NASA led the development of the website for the task force.
“NASA, together with our partner agencies, has studied climate change and Earth’s rising seas for decades,” said Karen St. Germain, director of the Earth Science Division at NASA Headquarters in Washington. “The data collected by our satellites and ground-based instruments is crucial to helping policymakers and communities prepare for the consequences of sea level rise. By combining NASA data with information from other federal agencies, the U.S. Sea Level Change website is the latest example of government working for the benefit of humanity.”
Demonstrating a whole-of-government approach, the sea level task force sits within the U.S. Global Change Research Program and includes leading researchers from NASA, the Department of Defense, the Environmental Protection Agency, the Federal Emergency Management Agency, the National Oceanic and Atmospheric Administration (NOAA), the U.S. Agency for International Development, the U.S. Army Corps of Engineers, and the U.S. Geological Survey.
They’ve designed a user-friendly hub that brings together information on sea level change from the various federal agencies. While being detailed and accurate for resource managers, researchers, and others seeking more technical information, the website is intended to be accessible to anyone interested in the latest science and strategies to cope with rising seas.
“Everyone will have access to accurate sea level and flooding information in their favorite U.S. coastal city and see the timing of the projected increase in water levels and flooding frequency,” added Nadya Vinogradova Shiffer, who directs NASA’s sea level change team as well as the ocean physics program at the agency’s headquarters in Washington.
The contributing federal agencies focus on different aspects of sea level rise, including basic scientific research and the effects of rising seas on the environment, as well as infrastructure. With the new site, users can explore the topic from different angles.
“Having this information in one place, delivered in a consistent and authoritative way through a true interagency effort, represents a big step forward for how the federal government helps coastal communities prepare for future sea level rise,” said Ben Hamlington, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California.
Site visitors can find explainers on sea level science, summaries of what rising seas will look like for various parts of U.S. coastlines, and updates to the 2022 interagency report on sea level rise. The report concluded that U.S. coastlines will experience an average of 10 to 12 inches (25 to 30 centimeters) of rise above current sea levels by 2050 and that the amount of rise in the next 30 years could equal the total rise seen over the past 100 years.
The report also outlined near-term sea level rise under various levels of greenhouse gas emissions, from best-case to business-as-usual to worst-case scenarios. The scenarios are based on improved scientific understanding of how melting glaciers and ice sheets — as well as upward and downward vertical land motion — will affect ocean heights at our coasts. The data and scenarios have been updated for the task force website.
NASA contributions to the 2022 interagency report, as well as to the newly launched sea level website, are part of ongoing agency work to understand Earth’s rising seas. NASA’s efforts to monitor the ocean span more than 30 years and include satellites such as Sentinel-6 Michael Freilich and the Surface Water and Ocean Topography (SWOT) mission. Both were jointly developed by the agency and international and domestic partners. Agency partners on Sentinel-6 Michael Freilich include ESA (European Space Agency), the European Organisation for the Exploitation of Meteorological Satellites, and NOAA. For SWOT, NASA partners include the French space agency CNES (Centre National d’Études Spatiales), CSA (the Canadian Space Agency), and the UK Space Agency.

Assignment: Safety and Mission Assurance Directorate, Space Habitation Systems Division, Computer Safety and Software Assurance Branch
Education: Mechanical Engineering, University of Wyoming; graduating December 2024
Proudest internship accomplishment: I am performing a hazard analysis on a spacesuit for armadillos for my exit presentation project. This was inspired by my “Texas to-do list” for the summer, which included seeing an armadillo. I also love iced coffee, and, for fun, I created a cartoon of an armadillo in a spacesuit drinking iced coffee. All of us at the safety review panel I was supporting had a good laugh about it, and it led to a conversation about the logistics of an armadillo in a spacesuit. This project demonstrates my ability to apply the knowledge I have learned during my internship, specifically in safety, to any situation accurately.
Favorite Johnson experience: On a professional level, it was the ability to work with JAXA personnel during the safety review panel for their new HTV-X. Working and building connections with international partners is an experience I will never forget! On a personal level, it was touring the Mission Control Center and seeing the sun rise and set live from the International Space Station!
Advice for incoming interns: Say yes to any opportunity you are presented with.

Assignment: Office of Communications
Education: Marketing, University of Houston’s Bauer School of Business; graduating December 2024
Proudest internship achievement: My intern project of creating and executing an employee engagement plan for NASA’s Boeing Crew Flight Test (CFT). I worked with two other interns to create a unique plan to get the Johnson workforce excited about the CFT launch. We created custom crew drinks with RoyalTEA & Coffee Co., held a crew sendoff event which also included a poster decorating party for employees, hosted CFT booths at center-wide events, and hung ‘Godspeed, Suni and Butch’ banners around campus. We ended the project with a fun viewing event for employees and their families.
Favorite Johnson experience: Planning the building 12 dedication that happened on July 19. The tasks have varied between planning the seating chart, writing scripts, and helping create the run of show for the event. But getting to experience the planning process of this event and seeing it come to life has been a surreal experience.
Important lesson learned: The true power of teamwork. It takes a village to accomplish all of the great things that happen here.

Proudest internship accomplishment: Serving as lead representative for CBCS in a safety review panel of an International Space Station payload.
Favorite Johnson experience: Working while surrounded by space history. There is always something going on, and something to see. It has been incredible to tour places like the Mission Control Center, Neutral Buoyancy Laboratory, and vacuum chambers. Also, it was pretty cool to meet an astronaut from my home country, Puerto Rico.
Important lesson learned: To persevere and step out of my comfort zone. I am working on concepts I have not worked on previously and are not taught in the classroom, therefore it has been a challenge to learn about them and contribute to the work. I took this challenge with a positive attitude and have been able to gain further understanding of systems engineering and CBCS and complete my tasks.
Courtney Thompson during a tour of Johnson Space Center’s Space Vehicle Mockup Facility. Courtney Thompson
Assignment: Center Operations Directorate, Logistics Division and Director’s Office
Education: Supply Chain Management, University of Nebraska-Lincoln; graduated December 2023
Proudest internship achievement: Getting here! Working at NASA was always the dream, though it didn’t seem like that was going to happen for me. I went back to school as a nontraditional business student a few years ago. I thought that would work against me but rolled the dice and here I am. Both my spring and summer internship mentors have been incredibly supportive during my time here. Temporary or not, this has been one of the best experiences of my life.
Important lesson learned: Remember what we are a part of. There are so many amazing things humanity has accomplished; many of those things are right here at NASA. Tour the facilities, ask questions, watch the launches, and celebrate and share with your friends. We are so lucky to get to witness these things up close and be a part of that history.
Advice for incoming interns: Always ask questions. Someone else probably has that question, too, or has never thought of things that way. It also helps show initiative and gets people to learn your name. Have a crazy new idea for something? Ask if it’s been done before or if it’s even feasible. And if they love the idea, you might just find more people to help make it happen.
Luis Valdez during a tour of Johnson Space Center’s Space Vehicle Mockup Facility. Luis Valdez
Assignment: Artificial Intelligence/Machine Learning – Software Development for Decision Intelligence Capability, Office of the Chief Information Officer’s Information, Data, and Analytics Services Team
Education: Computer Science, Texas A&M University; graduating May 2026
Proudest internship achievement: I’m proud of how much I’ve been able to learn and get done as the only intern on my project. It was pretty daunting at first, but I also saw it as an opportunity to show what I have to offer. Also, networking with other interns, civil servants, and even other companies like Google has been a dream come true.
Important lesson learned: Everything always changes. At the beginning of my internship, there was no clear path for me to take to achieve our objective, so it was all up to me to make the vision come to life. If something wasn’t working out, or if the customer wanted something different that wasn’t possible, I changed my methods to make it possible.
Advice for incoming interns: Get involved. Let yourself integrate fully into this internship. It’s a once-in-a-lifetime experience and working at NASA has been the dream of millions of people so make sure you take it all in. Also, connect with your mentor! They have so much to offer, and they truly want the best for you.
