Preparations for Next Moonwalk Simulations Underway (and Underwater)
Knowing whether or not a planet elsewhere in the galaxy could potentially be habitable requires knowing a lot about that planet’s sun. Sarah Peacock relies on computer models to assess stars’ radiation, which can have a major influence on whether or not one of these exoplanets has breathable atmosphere.
Name: Sarah Peacock
Title: Assistant Research Scientist
Formal Job Classification: Astrophysicist
Organization: Exoplanets and Stellar Astrophysics Laboratory, Astrophysics Division, Science Directorate (Code 667)
Sarah Peacock is a research scientist with the Exoplanets and Stellar Astrophysics Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Md.Courtesy of Sarah Peacock What do you do and what is most interesting about your role here at Goddard?
My overarching research goal is to find habitable planets in other solar systems. To do this, I study the high-energy radiation that specific stars produce to help determine if life can exist on any earthlike planets that orbit them.
What is your educational background?
In 2013, I received a Bachelor of Arts in astrophysics from the University of Virginia. I received both my master’s and doctorate degrees from the Lunar and Planetary Laboratory at the University of Arizona in 2016 and 2019, respectively.
What drew you to study the stars?
In high school, I took an astronomy class. We had a planetarium in our school and I had a wonderful teacher who inspired me to fall in love with the stars. She also showed us how many of the Harry Potter characters are drawn from the constellations and that spoke to my heart because I am a Harry Potter fan!
How did you come to Goddard?
I started at Goddard as a NASA post-doctoral fellow in July 2020, but I first saw the center the day before Goddard shut down due to COVID.
How does high-energy radiation show you what planets outside our solar system might be habitable?
High-energy radiation can cause a planet to lose its atmosphere. If a planet is exposed to too much high-energy radiation, the atmosphere can be blown off, and if there is no atmosphere, then there is nothing for life as we know it to breathe.
We cannot directly measure the specific radiation that I study, so we have to model it. The universe has so many stars, and almost all stars host a planet. There are approximately 5,500 confirmed exoplanets so far, with an additional 7,500 unconfirmed exoplanets.
I help identify systems that either have too much radiation, so planets in the habitable zone (the region around a star where liquid water could exist on a planet’s surface) are probably lifeless, or systems that have radiation levels that are safer. Ultimately, my research helps narrow down the most likely systems to host planets that should have stable atmospheres.
Sarah Peacock research goal is to find habitable planets in other solar systems.Courtesy of Sarah Peacock Where does your data come from?
I predominately use data from the Hubble Space Telescope and from the now-retired spacecraft GALEX. My work itself is more theory-focused though: I create a modeled stellar spectrum across all wavelengths and use observations to validate my modeling.
What other areas of research are you involved in?
I am working with a team analyzing data from the James Webb Space Telescope to see if earthlike planets around M-type stars (a star that is cooler and smaller than the Sun) have atmospheres and, if so, what the composition of those atmospheres is. An exciting result from this work is that we may have detected water in the atmosphere of a rocky planet for the first time ever. However, we cannot yet distinguish with our current observations if that water comes from the planet or from spots on the star (starspots on this host star are cold enough for water to exist in gas form).
I am also helping manage a NASA Innovative Advance Concept (NIAC) study led by my mentor, Ken Carpenter, to work on the Artemis Enabled Stellar Imager (AeSI). If selected for further development, this imager would be an ultraviolet/optical interferometer located on the South Pole of the Moon. With this telescope, we would be able to map the surface of stars, image accretion disks, and image the centers of Active Galactic Nuclei.
As a relatively new employee to Goddard, what have been your first impressions?
Everyone who I have met, especially those in my lab, are incredibly friendly and welcoming. Starting during the pandemic, I was worried about feeling isolated, but instead, I was blown away by how many folks in my lab reached out to set up calls to introduce themselves and suggest opportunities for collaboration. It made me feel welcome.
Who is your mentor and what did your mentor advise you?
Ken Carpenter is my mentor. He encourages me to pursue my aspirations. He supports letting me chart my own path and being exposed to many different areas of research. I thank Ken for his support and encouragement and for including me on his projects.
“Everyone who I have met, especially those in my lab, are incredibly friendly and welcoming.”Courtesy of Sarah Peacock What do you do for fun?
I am a new mom, so my usual hobbies are on pause! Right now, fun is taking care of my baby and introducing life experiences to him.
As a recently selected member of the Executive Committee for NASA’s Exoplanet Exploration Program Analysis Group (ExoPAG), what are your responsibilities?
The NASA ExoPAG is responsible for soliciting and coordinating scientific community input into the development and execution of NASA’s exoplanet exploration program. We solicit opinions and advice from any scientist who studies exoplanets. We are a bridge between NASA’s exoplanet scientists and NASA Headquarters in Washington.
What is a fun fact about yourself?
I got married the same day I defended my Ph.D. I had my defense in the morning and got married in the afternoon at the courthouse.
Who is your favorite author?
I love to read; I always have three books going. My favorite author is Louise Penny, who writes mysteries, but I read all genres. Right now, I am reading a biography about Marjorie Merriweather Post.
What is your favorite quote?
“The most that can be expected from any model is that it can supply a useful approximation to reality: All models are wrong; some models are useful.” —Box and Draper 1987

9 Min Read Towards Autonomous Surface Missions on Ocean Worlds

NASA/JPL – Caltech Through advanced autonomy testbed programs, NASA is setting the groundwork for one of its top priorities—the search for signs of life and potentially habitable bodies in our solar system and beyond. The prime destinations for such exploration are bodies containing liquid water, such as Jupiter’s moon Europa and Saturn’s moon Enceladus. Initial missions to the surfaces of these “ocean worlds” will be robotic and require a high degree of onboard autonomy due to long Earth-communication lags and blackouts, harsh surface environments, and limited battery life.
Technologies that can enable spacecraft autonomy generally fall under the umbrella of Artificial Intelligence (AI) and have been evolving rapidly in recent years. Many such technologies, including machine learning, causal reasoning, and generative AI, are being advanced at non-NASA institutions.
NASA started a program in 2018 to take advantage of these advancements to enable future icy world missions. It sponsored the development of the physical Ocean Worlds Lander Autonomy Testbed (OWLAT) at NASA’s Jet Propulsion Laboratory in Southern California and the virtual Ocean Worlds Autonomy Testbed for Exploration, Research, and Simulation (OceanWATERS) at NASA’s Ames Research Center in Silicon Valley, California.
NASA solicited applications for its Autonomous Robotics Research for Ocean Worlds (ARROW) program in 2020, and for the Concepts for Ocean worlds Life Detection Technology (COLDTech) program in 2021. Six research teams, based at universities and companies throughout the United States, were chosen to develop and demonstrate autonomy solutions on OWLAT and OceanWATERS. These two- to three-year projects are now complete and have addressed a wide variety of autonomy challenges faced by potential ocean world surface missions.
OWLAT
OWLAT is designed to simulate a spacecraft lander with a robotic arm for science operations on an ocean world body. The overall OWLAT architecture including hardware and software components is shown in Figure 1. Each of the OWLAT components is detailed below.
Figure 1. The software and hardware components of the Ocean Worlds Lander Autonomy Testbed and the relationships between them. NASA/JPL – Caltech The hardware version of OWLAT (shown in Figure 2) is designed to physically simulate motions of a lander as operations are performed in a low-gravity environment using a six degrees-of-freedom (DOF) Stewart platform. A seven DOF robot arm is mounted on the lander to perform sampling and other science operations that interact with the environment. A camera mounted on a pan-and-tilt unit is used for perception. The testbed also has a suite of onboard force/torque sensors to measure motion and reaction forces as the lander interacts with the environment. Control algorithms implemented on the testbed enable it to exhibit dynamics behavior as if it were a lightweight arm on a lander operating in different gravitational environments.
Figure 2. The Ocean Worlds Lander Autonomy Testbed. A scoop is mounted to the end of the testbed robot arm. NASA/JPL – Caltech The team also developed a set of tools and instruments (shown in Figure 3) to enable the performance of science operations using the testbed. These various tools can be mounted to the end of the robot arm via a quick-connect-disconnect mechanism. The testbed workspace where sampling and other science operations are conducted incorporates an environment designed to represent the scene and surface simulant material potentially found on ocean worlds.
Figure 3. Tools and instruments designed to be used with the testbed. NASA/JPL – Caltech The software-only version of OWLAT models, visualizes, and provides telemetry from a high-fidelity dynamics simulator based on the Dynamics And Real-Time Simulation (DARTS) physics engine developed at JPL. It replicates the behavior of the physical testbed in response to commands and provides telemetry to the autonomy software. A visualization from the simulator is shown on Figure 4.

Figure 7. Screenshot of OceanWATERS lander on a terrain modeled from the Atacama Desert. A scoop operation has just been completed. NASA/JPL – Caltech The autonomy software module shown at the top in Figure 1 interacts with the testbed through a Robot Operating System (ROS)-based interface to issue commands and receive telemetry. This interface is defined to be identical to the OceanWATERS interface. Commands received from the autonomy module are processed through the dispatcher/scheduler/controller module (blue box in Figure 1) and used to command either the physical hardware version of the testbed or the dynamics simulation (software version) of the testbed. Sensor information from the operation of either the software-only or physical testbed is reported back to the autonomy module using a defined telemetry interface. A safety and performance monitoring and evaluation software module (red box in Figure 1) ensures that the testbed is kept within its operating bounds. Any commands causing out of bounds behavior and anomalies are reported as faults to the autonomy software module.

At the time of the OceanWATERS project’s inception, Jupiter’s moon Europa was planetary science’s first choice in searching for life. Based on ROS, OceanWATERS is a software tool that provides a visual and physical simulation of a robotic lander on the surface of Europa (see Figure 6). OceanWATERS realistically simulates Europa’s celestial sphere and sunlight, both direct and indirect. Because we don’t yet have detailed information about the surface of Europa, users can select from terrain models with a variety of surface and material properties. One of these models is a digital replication of a portion of the Atacama Desert in Chile, an area considered a potential Earth-analog for some extraterrestrial surfaces.
Figure 6. Screenshot of OceanWATERS. NASA/JPL – Caltech JPL’s Europa Lander Study of 2016, a guiding document for the development of OceanWATERS, describes a planetary lander whose purpose is collecting subsurface regolith/ice samples, analyzing them with onboard science instruments, and transmitting results of the analysis to Earth.
The simulated lander in OceanWATERS has an antenna mast that pans and tilts; attached to it are stereo cameras and spotlights. It has a 6 degree-of-freedom arm with two interchangeable end effectors—a grinder designed for digging trenches, and a scoop for collecting ground material. The lander is powered by a simulated non-rechargeable battery pack. Power consumption, the battery’s state, and its remaining life are regularly predicted with the Generic Software Architecture for Prognostics (GSAP) tool. To simulate degraded or broken subsystems, a variety of faults (e.g., a frozen arm joint or overheating battery) can be “injected” into the simulation by the user; some faults can also occur “naturally” as the simulation progresses, e.g., if components become over-stressed. All the operations and telemetry (data measurements) of the lander are accessible via an interface that external autonomy software modules can use to command the lander and understand its state. (OceanWATERS and OWLAT share a unified autonomy interface based on ROS.) The OceanWATERS package includes one basic autonomy module, a facility for executing plans (autonomy specifications) written in the PLan EXecution Interchange Language, or PLEXIL. PLEXIL and GSAP are both open-source software packages developed at Ames and available on GitHub, as is OceanWATERS.
Mission operations that can be simulated by OceanWATERS include visually surveying the landing site, poking at the ground to determine its hardness, digging a trench, and scooping ground material that can be discarded or deposited in a sample collection bin. Communication with Earth, sample analysis, and other operations of a real lander mission, are not presently modeled in OceanWATERS except for their estimated power consumption. Figure 7 is a video of OceanWATERS running a sample mission scenario using the Atacama-based terrain model.

Figure 7. Screenshot of OceanWATERS lander on a terrain modeled from the Atacama Desert. A scoop operation has just been completed. NASA/JPL – Caltech Because of Earth’s distance from the ocean worlds and the resulting communication lag, a planetary lander should be programmed with at least enough information to begin its mission. But there will be situation-specific challenges that will require onboard intelligence, such as deciding exactly where and how to collect samples, dealing with unexpected issues and hardware faults, and prioritizing operations based on remaining power.
Results
All six of the research teams funded by the ARROW and COLDTech programs used OceanWATERS to develop ocean world lander autonomy technology and three of those teams also used OWLAT. The products of these efforts were published in technical papers, and resulted in development of software that may be used or adapted for actual ocean world lander missions in the future.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Diana Oglesby’s love for NASA began long before she started working for the agency. A native of Decatur, Texas, Oglesby knew at the age of eight that she would make NASA her future destination. That dream became a reality when Oglesby joined the agency, first as an intern and later as a NASA full-time employee, marking the beginning of a career that would span over two decades.
From left, Richard Jones, CCP (Commercial Crew Program) deputy program manager at NASA’s Johnson Space Center in Houston; Steve Stich, program manager for CCP; Dana Hutcherson, CCP deputy program manager at NASA’s Kennedy Space Center in Florida; and Diana Oglesby, director, Strategic Integration and Management Division, Space Operations Mission Directorate, pose with the agency’s SpaceX Crew-9 mission flag near the countdown clock at the NASA News Center at the Kennedy on Tuesday, Sept. 24, 2024.NASA/Cory S Huston Oglesby currently serves as director of the Strategic Integration and Management Division within NASA’s Space Operations Mission Directorate at NASA Headquarters. The division plays a key role in ensuring the effectiveness and efficiency of space operations, providing essential business support such as programmatic integration, strategic planning, information technology and cybersecurity leadership, stakeholder outreach, and administrative services.
Before her current role, Oglesby led the business management function for NASA’s Commercial Crew Program at NASA’s Kennedy Space Center in Florida. She had a front-row seat to history during NASA’s SpaceX Demo-2 mission, which successfully launched astronauts to the International Space Station in the first commercially built and operated American rocket and spacecraft, marking a significant milestone in NASA’s space exploration efforts.
“It was an honor of a lifetime,” she says, reflecting on her role in this historic achievement.
Oglesby’s ability to foster teamwork and genuine care for others has been a hallmark of her career, whether serving in NASA’s Commercial Crew Program or now guiding the Strategic Integration and Management Division.
While reflecting on her new role as division director, Oglesby is most excited about the people. As someone who thrives on diverse activities and complex challenges, she looks forward to the strategic aspects of her role and the opportunity to lead a dynamic team helping to shape NASA’s future.

Born and raised in Mexico City, Carlos Fontanot has dedicated 34 years to NASA. He supports the International Space Station Mission Integration and Operations Office, ensuring that high-quality imagery enhances mission objectives and operations.
Fontanot is known for conceiving and leading the High Definition Earth Viewing (HDEV) project, which has brought stunning live visuals of Earth to millions around the globe. As he approaches his well-deserved retirement, we are excited to spotlight Fontanot’s remarkable career, celebrating his contributions to NASA and the lasting impact he has made on the agency’s mission to share the wonders of space.
Carlos Fontanot (left) receives the Great Minds in STEM Lifetime Achievement Award from Joel Montelbano, NASA at the Hispanic Engineer National Achievement Award Conference. What does your position entail?
Integrate all aspects of station imagery, from initial requirements to acquisition, processing, cataloging, archiving, and distribution of station imagery to multiple stakeholders, our clients.
How would you describe your job to family or friends who may not be as familiar with NASA?
I manage an array of television and digital still imagery cameras on the International Space Station. Each day we receive eight channels of high definition (HD) video and thousands of digital images that allow the ground team to see what the crew is doing in their daily lives and as part of scientific activities. In today’s age of social media and high-quality imagery, having these images is crucial for effectively conveying the station narrative.
I also chair the International Space Station’s Multilateral Imagery Working Group. Our team captures and processes the video and still images on a large server, where they are cataloged, archived, and distributed to our clients. Additionally, we are responsible for the photo and TV hardware aboard the space station and provide training to astronauts on how to use this equipment.
Carlos Fontanot with Liam Kennedy at the International Space Station Research and Development Conference. How do you feel the imagery and public affairs teams contribute to the overall mission of NASA?
Imagery is critical for communication in today’s visual environment. If people can’t see it, they won’t believe it! Effective communication through multimedia and pointed messaging is essential for securing continued support for NASA missions from both Congress and the public.
What was your path to NASA?
I was always interested in photography and film, so I studied radio, TV, and film in college. My first job after graduation was with a local TV station, and I also managed a media center for a multinational company. Then, I joined Johnson Space Center’s television and film division, where I managed space shuttle and institutional imagery.
Once at Johnson, I worked in the Office of Public Affairs as the audiovisual manager and served for two years as the public affairs officer in Moscow at the start of the International Space Station Program, including the launch of the first station crew.
What advice would you give to young individuals aspiring to work in the space industry or at NASA?
NASA is not just about astronauts, flight controllers, and engineers—there are countless disciplines and job opportunities here. Take imagery, for example: in today’s digital age, having the highest resolution imagery of our incredible orbiting laboratory environment and our home planet is essential.
For those aspiring to join the NASA team, I encourage you be open-minded and a team player. We need well-educated and talented individuals from diverse backgrounds across all disciplines to help us achieve our goals and explore the wonders of space.
Is there a space figure you’ve looked up to?
The space figure I will always remember and look up to is John Glenn. I had the fortune and privilege to meet him during his training. He was an extraordinary human being with incredibly high goals throughout his career.
I was assigned to escort John Glenn and the STS-95 crew on a two-week official visit to several European countries. John was by far the most inspiring and dedicated crew member that I’d ever met. He was always ready and willing to engage with dignitaries, politicians, leaders, journalists, and the public to share the NASA story and promote future programs to gain support from various governments and the public.
What do you love sharing about the International Space Station to general audiences?
I love sharing the wonders of life in space, especially the unique and breathtaking views of our planet Earth that can only be appreciated from space. I like to tell audiences about the observations and inspiration our astronauts share upon returning from their missions. I emphasize our thin and fragile atmosphere that sustains life as we know it, the beauty of Earth’s deserts, mountains, jungles, and oceans, and most importantly, the absence of borders. There’s always a profound realization that we are all human and that Earth belongs to all of us.
How has the technology for capturing images and video in space evolved over the years?
There was no digital imagery when I started my professional career. Photographs were taken on film that had to be processed in a dark room using chemicals to produce images. Video was recorded on two-inch magnetic tape at low resolution. We even flew film on our spacecraft that had to be brought back and processed on the ground.
Today, in the digital world, images can be streamed directly from our spacecraft and almost instantaneously shared with the entire globe. The evolution of technology has truly transformed how we capture and share the wonders of space!
Carlos Fontanot (left) sets up a NASA imagery exhibit in the Houston Downtown Tunnel System. What are some of the key projects you’ve worked on during your time at NASA? What have been your favorites?
During my time at NASA, I co-led the High Definition Earth Viewing (HDEV) project, which deployed four Earth-viewing cameras on the International Space Station, reaching over 318 million viewers globally. I also contributed to designing Johnson’s new PAO studio, collaborated on upgrading the space station’s downlink system from four standard-definition to eight high-definition channels, and advanced television technology, including the first HD and later UHD live downlinks from the station. These projects have allowed me to enhance NASA’s capacity for sharing space imagery with the world.
What are your plans for retirement, and how do you hope to stay connected to the space community?
I plan to travel across the U.S. in a travel trailer with my wife and dog and enjoying my hobbies I will now have time for, such as photography and spending quality time with my family.
Carlos and Pat Fontanot at the Grand Canyon South Rim in Arizona. How do you believe NASA’s imagery can continue to inspire future generations?
Astronaut John Young would come to the photo lab after every shuttle mission to review the film shot onboard. He would say, “A picture is worth a thousand words.” What can inspire more than a breathtaking image of a sunset captured from space or the aurora borealis over the polar regions?
What legacy do you hope to leave behind after your time at NASA?
I hope to leave behind a legacy of passion and dedication to acquiring and making pristine, high-resolution imagery from space available for the public to enjoy.
If you could have dinner with any astronaut, past or present, who would it be?
I would choose John Young. He flew during both the Apollo and shuttle eras, was an imagery expert, and had a deep understanding of the space station.
