Preparations for Next Moonwalk Simulations Underway (and Underwater)
Located off the coast of Ecuador, Paramount seamount is among the kinds of ocean floor features that certain ocean-observing satellites like SWOT can detect by how their gravitational pull affects the sea surface.NOAA Okeanos Explorer Program More accurate maps based on data from the SWOT mission can improve underwater navigation and result in greater knowledge of how heat and life move around the world’s ocean.
There are better maps of the Moon’s surface than of the bottom of Earth’s ocean. Researchers have been working for decades to change that. As part of the ongoing effort, a NASA-supported team recently published one of the most detailed maps yet of the ocean floor, using data from the SWOT (Surface Water and Ocean Topography) satellite, a collaboration between NASA and the French space agency CNES (Centre National d’Études Spatiales).
Ships outfitted with sonar instruments can make direct, incredibly detailed measurements of the ocean floor. But to date, only about 25% of it has been surveyed in this way. To produce a global picture of the seafloor, researchers have relied on satellite data.
This animation shows seafloor features derived from SWOT data on regions off Mexico, South America, and the Antarctic Peninsula. Purple denotes regions that are lower relative to higher areas like seamounts, depicted in green. Eötvös is the unit of measure for the gravity-based data used to create these maps.
NASA’s Scientific Visualization Studio Why Seafloor Maps Matter
More accurate maps of the ocean floor are crucial for a range of seafaring activities, including navigation and laying underwater communications cables. “Seafloor mapping is key in both established and emerging economic opportunities, including rare-mineral seabed mining, optimizing shipping routes, hazard detection, and seabed warfare operations,” said Nadya Vinogradova Shiffer, head of physical oceanography programs at NASA Headquarters in Washington.
Accurate seafloor maps are also important for an improved understanding of deep-sea currents and tides, which affect life in the abyss, as well as geologic processes like plate tectonics. Underwater mountains called seamounts and other ocean floor features like their smaller cousins, abyssal hills, influence the movement of heat and nutrients in the deep sea and can attract life. The effects of these physical features can even be felt at the surface by the influence they exert on ecosystems that human communities depend on.

Purple denotes regions that are lower relative to higher areas like seamounts, indicated with green. Eötvös is the unit of measure for the gravity-based data used to create these maps.NASA Earth Observatory Mapping the seafloor isn’t the SWOT mission’s primary purpose. Launched in December 2022, the satellite measures the height of water on nearly all of Earth’s surface, including the ocean, lakes, reservoirs, and rivers. Researchers can use these differences in height to create a kind of topographic map of the surface of fresh- and seawater. This data can then be used for tasks such as assessing changes in sea ice or tracking how floods progress down a river.
“The SWOT satellite was a huge jump in our ability to map the seafloor,” said David Sandwell, a geophysicist at Scripps Institution of Oceanography in La Jolla, California. He’s used satellite data to chart the bottom of the ocean since the 1990s and was one of the researchers responsible for the SWOT-based seafloor map, which was published in the journal Science in December 2024.
How It Works
The study authors relied the fact that because geologic features like seamounts and abyssal hills have more mass than their surroundings, they exert a slightly stronger gravitational pull that creates small, measurable bumps in the sea surface above them. These subtle gravity signatures help researchers predict the kind of seafloor feature that produced them.
Through repeated observations — SWOT covers about 90% of the globe every 21 days — the satellite is sensitive enough to pick up these minute differences, with centimeter-level accuracy, in sea surface height caused by the features below. Sandwell and his colleagues used a year’s worth of SWOT data to focus on seamounts, abyssal hills, and underwater continental margins, where continental crust meets oceanic crust.
Previous ocean-observing satellites have detected massive versions of these bottom features, such as seamounts over roughly 3,300 feet (1 kilometer) tall. The SWOT satellite can pick up seamounts less than half that height, potentially increasing the number of known seamounts from 44,000 to 100,000. These underwater mountains stick up into the water, influencing deep sea currents. This can concentrate nutrients along their slopes, attracting organisms and creating oases on what would otherwise be barren patches of seafloor.
Looking Into the Abyss
The improved view from SWOT also gives researchers more insight into the geologic history of the planet.
“Abyssal hills are the most abundant landform on Earth, covering about 70% of the ocean floor,” said Yao Yu, an oceanographer at Scripps Institution of Oceanography and lead author on the paper. “These hills are only a few kilometers wide, which makes them hard to observe from space. We were surprised that SWOT could see them so well.”
Abyssal hills form in parallel bands, like the ridges on a washboard, where tectonic plates spread apart. The orientation and extent of the bands can reveal how tectonic plates have moved over time. Abyssal hills also interact with tides and deep ocean currents in ways that researchers don’t fully understand yet.
The researchers have extracted nearly all the information on seafloor features they expected to find in the SWOT measurements. Now they’re focusing on refining their picture of the ocean floor by calculating the depth of the features they see. The work complements an effort by the international scientific community to map the entire seafloor using ship-based sonar by 2030. “We won’t get the full ship-based mapping done by then,” said Sandwell. “But SWOT will help us fill it in, getting us close to achieving the 2030 objective.”
More About SWOT
The SWOT satellite was jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and the UK Space Agency. NASA’s Jet Propulsion Laboratory, managed for the agency by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system payload, NASA provided the Ka-band radar interferometer (KaRIn) instrument, a GPS science receiver, a laser retroreflector, a two-beam microwave radiometer, and NASA instrument operations. The Doppler Orbitography and Radioposition Integrated by Satellite system, the dual frequency Poseidon altimeter (developed by Thales Alenia Space), the KaRIn radio-frequency subsystem (together with Thales Alenia Space and with support from the UK Space Agency), the satellite platform, and ground operations were provided by CNES. The KaRIn high-power transmitter assembly was provided by CSA.

James Gentile always wanted to fly. As he prepared for an appointment to the U.S. Air Force Academy to become a pilot, life threw him an unexpected curve: a diagnosis of Type 1 diabetes. His appointment was rescinded.
With his dream grounded, Gentile had two choices—give up or chart a new course. He chose the latter, pivoting to aerospace engineering. If he could not be a pilot, he would design the flight simulations that trained those who could.
Official portrait of James Gentile. NASA/Robert Markowitz As a human space vehicle simulation architect at NASA’s Johnson Space Center in Houston, Gentile leads the Integrated Simulation team, which supports the Crew Compartment Office within the Simulation and Graphics Branch. He oversees high-fidelity graphical simulations that support both engineering analysis and flight crew training for the Artemis campaign.
His team provides critical insight into human landing system vendor designs, ensuring compliance with NASA’s standards. They also develop human-in-the-loop simulations to familiarize teams with the challenges of returning humans to the lunar surface, optimizing design and safety for future space missions.
“I take great pride in what I have helped to build, knowing that some of the simulations I developed have influenced decisions for the Artemis campaign,” Gentile said.
One of the projects he is most proud of is the Human Landing System CrewCo Lander Simulation, which helps engineers and astronauts tackle the complexities of lunar descent, ascent, and rendezvous. He worked his way up from a developer to managing and leading the project, transforming a basic lunar lander simulation into a critical tool for the Artemis campaign.
What began as a simple model in 2020 is now a key training asset used in multiple facilities at Johnson. The simulation evaluates guidance systems and provides hands-on piloting experience for lunar landers.

NASA/James Blair Before joining Johnson as a contractor in 2018, Gentile worked in the aviation industry developing flight simulations for pilot training. Transitioning to the space sector was challenging at first, particularly working alongside seasoned professionals who had been part of the space program for years.
“I believe my experience in the private sector has benefited my career,” he said. “I’ve been able to bring a different perspective and approach to problem-solving that has helped me advance at Johnson.”
Gentile attributes his success to never being afraid to speak up and ask questions. “You don’t always have to be the smartest person in the room to make an impact,” he said. “I’ve been able to show my value through my work and by continuously teaching myself new skills.”
As he helps train the Artemis Generation, Gentile hopes to pass on his passion for aerospace and simulation development, inspiring others to persevere through obstacles and embrace unexpected opportunities.
“The most important lessons I’ve learned in my career are to build and maintain relationships with your coworkers and not to be afraid to step out of your comfort zone,” he said.

Following the historic year of 1969 that saw two successful Moon landings, 1970 opened on a more sober note. Ever-tightening federal budgets forced NASA to rescope its future lunar landing plans. The need for a Saturn V to launch an experimental space station in 1972 forced the cancellation of the final Moon landing mission and an overall stretching out of the Moon landing flights. Apollo 13 slipped to April, but the crew of James Lovell, Thomas “Ken” Mattingly, and Fred W. Haise and their backups John Young, John “Jack” Swigert, and Charles Duke continued intensive training for the landing at Fra Mauro. Training included practicing their surface excursions and water egress, along with time in spacecraft simulators. The three stages of the Apollo 14 Saturn V arrived at the launch site and workers began the stacking process for that mission now planned for October 1970. Scientists met in Houston to review the preliminary findings from their studies of the lunar samples returned by Apollo 11.
Apollo Program Changes
Apollo Moon landing plans in early 1970, with blue indicating completed landings, green planned landings at the time, and red canceled landings. Illustration of the Apollo Applications Program, later renamed Skylab, experimental space station then planned for 1972. On Jan. 4, 1970, NASA Deputy Administrator George Low announced the cancellation of Apollo 20, the final planned Apollo Moon landing mission. The agency needed the Saturn V rocket that would have launched Apollo 20 to launch the Apollo Applications Program (AAP) experimental space station, renamed Skylab in February 1970. Since previous NASA Administrator James Webb had precluded the building of any additional Saturn V rockets in 1968, this proved the only viable yet difficult solution.
In other program changes, on Jan. 13 NASA Administrator Thomas Paine addressed how NASA planned to deal with ongoing budgetary challenges. Lunar landing missions would now occur every six months instead of every four, and with the slip of Apollo 13 to April, Apollo 14 would now fly in October instead of July. Apollo 15 and 16 would fly in 1971, then AAP would launch in 1972, and three successive crews would spend, 28, 56, and 56 days aboard the station. Lunar landing missions would resume in 1973, with Apollo 17, 18, and 19 closing out the program by the following year.

Wernher von Braun in his office at NASA Headquarters in Washington, D.C. In addition to programmatic changes, several key management changes took place at NASA in January 1970. On Nov. 26, 1969, Christopher Kraft , the director of flight operations at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston, assumed the position of MSC deputy director. On Dec. 28, MSC Director Robert Gilruth named Sigurd “Sig” Sjoberg, deputy director of flight operations since 1963, to succeed Kraft. At NASA Headquarters in Washington, D.C., Associate Administrator for Manned Space Flight George Mueller resigned his position effective Dec. 10, 1969. To replace Mueller, on Jan. 8, NASA Administrator Paine named Dale Myers, vice president and general manager of the space shuttle program at North American Rockwell Corporation. On Jan. 27, Paine announced that Wernher von Braun, designer of the Saturn family of rockets and director of the Marshall Space Flight Center in Huntsville, Alabama, since its establishment in 1960, would move to NASA Headquarters and assume the position of deputy associate administrator for planning.
Apollo 11 Lunar Science Symposium

Between Jan. 5 and 8, 1970, several hundred scientists, including all 142 U.S. and international principal investigators provided with Apollo 11 samples, gathered in downtown Houston’s Albert Thomas Exhibit and Convention Center for the Apollo 11 Lunar Science Conference. During the conference, the scientists discussed the chemistry, mineralogy, and petrology of the lunar samples, the search for carbon compounds and any evidence of organic material, the results of dating of the samples, and the results returned by the Early Apollo Surface Experiments Package (EASEP). Senior NASA managers including Administrator Paine, Deputy Administrator Low, and Apollo Program Director Rocco Petrone attended the conference, and Apollo 11 astronaut Edwin “Buzz” Aldrin gave a keynote speech at a dinner reception. The prestigious journal Science dedicated its Jan. 30, 1970, edition to the papers presented at the conference, dubbing it “The Moon Issue”. The Lunar Science Conference evolved into an annual event, renamed the Lunar and Planetary Science Conference in 1978, and continues to attract scientists from around the world to discuss the latest developments in lunar and planetary exploration.

Actress June Lockhart, an avid space enthusiast, interviewed them during the TV broadcast of the event. As President Richard Nixon had earlier requested, Conrad, Gordon, and Bean and their wives paid a visit to former President Lyndon B. Johnson and First Lady Lady Bird Johnson at their ranch near Fredericksburg, Texas, on Jan. 14, 1970. The astronauts described their mission to the former President and Mrs. Johnson.

Engineers there completed a thorough inspection of the spacecraft and eventually prepared it for public display. NASA transferred Yankee Clipper to the Smithsonian Institution in 1973, and today the capsule resides at the Virginia Air & Space Center in Hampton, Virginia. NASA also released from quarantine the lunar samples and the parts of the Surveyor 3 spacecraft returned by the Apollo 12 astronauts. The scientists received their allocated samples in mid-February, while after initial examination in the Lunar Receiving Laboratory (LRL) the Surveyor parts arrived at NASA’s Jet Propulsion Laboratory in Pasadena, California, for detailed analysis.
Apollo 13
As the first step in the programmatic rescheduling of all Moon landings, on Jan. 7, NASA announced the delay of the Apollo 13 launch from March 12 to April 11. The Saturn V rocket topped with the Apollo spacecraft had rolled out the previous December to Launch Pad 39A where workers began tests on the vehicle. The prime crew of Lovell, Mattingly, and Haise, and their backups Young, Swigert, and Duke, continued to train for the 10-day mission to land in the Fra Mauro region of the Moon.

Apollo 13 prime crew members Lovell, Mattingly, and Haise completed their water egress training in the Gulf of Mexico near the coast of Galveston, Texas, on Jan. 24. With support from the Motorized Vessel Retriever, the three astronauts entered a boilerplate Apollo CM. Sailors lowered the capsule into the water, first in the Stable 2 or apex down position. Three self-inflating balloons righted the spacecraft into the Stable 1 apex up position within a few minutes. With assistance from the recovery team, Lovell, Mattingly, and Haise exited the spacecraft onto a life raft. A helicopter lifted them out of the life rafts using Billy Pugh nets and returned them to Retriever. Later that day, the astronauts returned to the MSC to examine Moon rocks in the LRL that the Apollo 12 astronauts had returned the previous November.
During their 33.5 hours on the Moon’s surface, Lovell and Haise planned to conduct two four-hour spacewalks to set up the Apollo Lunar Surface Experiment Package (ALSEP), a suite of five investigations designed to collect data about the lunar environment after the astronauts’ departure, and to conduct geologic explorations of the landing site. Mattingly planned to remain in the Command and Service Module (CSM), conducting geologic observations from lunar orbit including photographing potential future landing sites. Lovell and Haise conducted several simulations of the spacewalk timelines, including setting up the ALSEP equipment, practicing taking core samples, and photographing their activities for documentation purposes. They and their backups conducted practice sessions with the partial gravity simulator, also known as POGO, an arrangement of harnesses and servos that simulated walking in the lunar one-sixth gravity. Lovell and Young completed several flights in the Lunar Landing Training Vehicle (LLTV) that simulated the flying characteristics of the Lunar Module (LM) for the final several hundred feet of the descent to the surface.

In the LRL, technicians prepared the Apollo Lunar Sample Return Containers (ALSRC), or rock boxes, for Apollo 13. Like all missions, Apollo 13 carried two ALSRCs, with each box and lid manufactured from a single block of aluminum. Workers placed sample containers and bags and two 2-cm core sample tubes inside the two ALSRCs. Once loaded, technicians sealed the boxes under vacuum conditions so that they would not contain pressure greater than lunar ambient conditions. Engineers at MSC prepared the American flag that Lovell and Haise planned to plant on the Moon for stowage on the LM’s forward landing strut.

The CSM and the LM had arrived at NASA’s Kennedy Space Center (KSC) in Florida late in 1969 and technicians conducted tests on the vehicles in the Manned Spacecraft Operations Building (MSOB). On Jan. 12, workers lowered the ascent stage of the LM onto the CSM to perform a docking test – the next time the two vehicles docked they would be on the way to the Moon and the test verified their compatibility. Workers mated the two stages of the LM on Jan. 20.

The three stages of the Apollo 14 Saturn V arrived in KSC’s cavernous Vehicle Assembly Building (VAB) in mid-January and while workers stacked the first stage on its Mobile Launch Platform on Jan. 14, they delayed stacking the remainder of the rocket stages until May 1970. That decision proved fortunate, since engineers needed to modify the second stage engines following the pogo oscillations experienced during the Apollo 13 launch.

To put boots on the Moon—and keep them there—will require bold thinkers ready to tackle the challenges of tomorrow.
That’s why NASA’s Office of STEM Engagement at Johnson Space Center in Houston is on a mission to empower the next generation of explorers in science, technology, engineering, and mathematics (STEM).
Through the High School Aerospace Scholars (HAS) program, Texas juniors have the opportunity to immerse themselves in space exploration through interactive learning experiences.
“HAS is such an important program because we introduce students to the multitude of careers and experiences that contribute to space exploration,” said NASA HAS Activity Manager Jakarda Varnado. “We go beyond asking students who they want to be when they grow up and ask what problems they want to solve.”
Meet Former HAS Student Madeline King
Madeline King always knew she wanted a career in STEM, with a dream of working at NASA influencing her decision to pursue a degree in Engineering.
Before joining HAS, King thought scientists mainly worked in labs and engineers focused on design. But the HAS program revealed a different reality—scientists and engineers often collaborated on interdisciplinary projects, sometimes even sharing roles.
Official portrait of Madeline King.NASA The program broadened King’s perspective on the diverse paths a STEM degree can lead to. It showed her that careers at NASA offer opportunities across various fields and disciplines.
King said participating in HAS helped to strengthen her problem-solving skills and ability to think creatively. The program required students to tackle complex technical tasks independently, emphasizing self-directed learning. King describes HAS as fun, challenging, and engaging, which helped her excel in technical roles.
“Learning to digest and internalize this information is a skill I continue to use when getting up to speed in new groups or taking on projects outside my current skill set,” said King.
Though King joined HAS during COVID-19, which limited in-person interactions, the experience still made an impact. Her mentors also offered insights into graduate school options, helping her weigh the benefits of advanced degrees against gaining hands-on experience at NASA.
The program opened doors to internships at Johnson in the Engineering Robotics and the Avionics Systems Integration Division. Now, she is studying mechanical engineering at the University of Houston, bringing passion and experience in electronics, robotics, education, project management, and aviation.
“Early on in my internship journey, HAS shined on my resume,” she said. “It demonstrated that I already had experience with NASA’s culture, values, and mission.”
Looking forward, King envisions herself as a flight controller, contributing to both the International Space Station Program and the Artemis campaign. Driven by her passion for NASA’s mission, King is just beginning her journey and is eager to be part of the future of space exploration.
“My internships since HAS have allowed me to make small contributions to both of these missions, and I’m excited to specialize as a full-time engineer,” said King.
Meet Caroline Vergara
As a first-generation student, Caroline Vergara lacked the resources to fully explore her interests in aerospace engineering, let alone envision what that career might look like. That all changed when she was accepted into NASA’s HAS program.
“The exposure to real-world innovation ignited my desire to be part of something bigger, something that pushes the boundaries of human knowledge and capability,” she said.
Caroline Vergara announces the launch of the model rocket she built during her time in the HAS program. NASA/David DeHoyos Touring NASA facilities and watching engineers work on projects opened her eyes to the possibilities in STEM. Today, Vergara is a propulsion design engineering intern at United Launch Alliance, contributing to the Vulcan rocket as a Brooke Owens Fellow.
Vergara initially thought working in STEM was mostly about writing equations or running simulations but HAS showed her it is so much more. “A STEM career is about curiosity, collaboration, and the power to change the world,” she said.
During the program, Vergara joined a team of students to tackle a mission simulation project. They called themselves “Charlie and the Rocket Factory” and designed a prototype rocket together. Working with peers from all over the country showed her the power of diverse perspectives. She experienced firsthand what it was like to be part of a team with a shared vision, working toward something bigger than themselves.
Vergara also discovered her love for 3D printing and computer-aided design through HAS. She spent hours fine-tuning designs, fascinated by the process of turning digital models into physical reality.
Her experience with HAS also sparked a desire to give back. She returned to her hometown to share her story and encourage other students to pursue STEM. Partnering with Johnson Community Engagement Lead Jessica Cordero, she organized video conferences with NASA engineers on International Women in Engineering Day to inspire a new wave of students to be part of space exploration.
“The aerospace industry is entering a new space age, and we have the unique opportunity to put humans back on the Moon and explore beyond,” she said.
Her advice to the Artemis Generation is: “Go for it! You could be part of the generation that changes humanity’s destiny.”
Caroline Vergara, University of Houston Class of 2025. As a mechanical engineering honors student at the University of Houston and chief engineer of Space City Rocketry, Vergara envisions contributing to the Artemis campaign and advancing NASA’s mission to explore the cosmos.
“My dream is to contribute to space exploration efforts that put humans back on the Moon and beyond, and to one day work in Mission Control Center, where I can help guide those historic missions into the future.”
Meet Iker Aguirre
For Iker Aguirre, the spark that ignited his journey toward a career in aerospace was lit by a passing conversation during his freshman year of high school. A senior classmate described the HAS program as a once-in-a-lifetime experience that cemented his passion for aerospace. That moment stayed with Aguirre, and when the opportunity arose, he did not hesitate to apply.
Iker Aguirre inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. “HAS showed me that in order to accomplish something as complex as Artemis, you need a well-rounded set of teams and individuals,” he said. “You don’t need to study aerospace to be in the aerospace industry!”
In 2020, Aguirre participated during the remote-only version of HAS, but he recalls that the program still gave him a much deeper understanding of the spaceflight industry.
Despite already being interested in aerospace, Aguirre says HAS broadened his horizons, showing him the diverse pathways into the field. Through collaborative projects with peers across Texas, he discovered that solving the challenges of space exploration requires more than just aerospace engineers.
The program’s emphasis on teamwork left a lasting impression. During his time with HAS, Aguirre found himself working alongside students from different backgrounds, each bringing unique perspectives to problem-solving. It introduced him to dedicated and passionate people with various personalities and cultures who all shared similar dreams and aspirations as him.
Aguirre credits HAS with not only refining his technical skills but also shaping his approach to innovation and teamwork. That experience paid off as he moved through his academic and professional journey, including Pathways program internships with NASA’s Johnson Space Center in Houston and Marshall Space Flight Center in Huntsville, Alabama.
“Getting connections at NASA through HAS helped me open many doors so far,” said Aguirre. “I met many good friends through HAS and my internship at Johnson, which I value to this day.”
Now pursuing a degree in rocket propulsion, with a focus on turbomachinery design, Aguirre remains committed to advancing space exploration. He hopes to contribute to humanity’s mobility in space, tackling challenges in rocket engine feed systems.
