The roadmap sets NASA on course for long-term lunar exploration under the Artemis campaign in preparation for future crewed missions to Mars.
Following an Architecture Concept Review, the 2024 updates include a revision of NASA’s Architecture Definition Document which details technical approaches and processes of the agency’s exploration plans, an executive overview, and 12 new white papers on key Moon to Mars topics.
“NASA’s Architecture Concept Review process is critical to getting us on a path to mount a human mission to Mars,” said NASA Associate Administrator Jim Free. “We’re taking a methodical approach to mapping out the decisions we need to make, understanding resource and technological trades, and ensuring we are listening to feedback from stakeholders.”
One newly released white paper highlights NASA’s decision to use fission power as the primary source of power on the Martian surface to sustain crews — the first of seven key decisions necessary for human Mars exploration. Fission power is a form of nuclear power unaffected by day and night cycles or potential dust storms on Mars.
New additions this year also include a broader, prioritized list of key architecture decisions that need to be made early in NASA’s plans to send humans to the Red Planet. Two new elements are now part of the agency’s Moon to Mars architecture — a lunar surface cargo lander and an initial lunar surface habitat. The lunar surface cargo lander will deliver logistics items, science and technology payloads, communications systems, and more. The initial surface habitat will house astronauts on the lunar surface to extend the crew size, range, and duration of exploration missions and enable crewed and uncrewed science opportunities.
The newest revision of the Architecture Definition Document adds more information about NASA’s decision road mapping process — how the agency decides which decisions must be made early in the planning process based on impacts to subsequent decisions — and a list of architecture-driven opportunities that help technology development organizations prioritize research into new technologies that will enable the Moon to Mars architecture.
“Identifying and analyzing high-level architecture decisions are the first steps to realizing a crewed Mars exploration campaign,” said Catherine Koerner, associate administrator, Exploration Systems Development Mission Directorate, NASA Headquarters in Washington. “Each yearly assessment cycle as part of our architecture process is moving us closer to ensuring we have a well thought out plan to accomplish our exploration objectives.”
NASA’s Moon to Mars architecture approach incorporates feedback from U.S. industry, academia, international partners, and the NASA workforce. The agency typically releases a series of technical documents at the end of its annual analysis cycle, including an update of the Architecture Definition Document and white papers that elaborate on frequently raised topics.
Under NASA’s Artemis campaign, the agency will establish the foundation for long-term scientific exploration at the Moon, land the next Americans and first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

Members belonging to one of three teams from Oakwood School aim their devices — armed with chocolate-coated-peanut candies — at a target during JPL’s annual Invention Challenge on Dec. 6.NASA/JPL-Caltech Teams competed with homemade devices to try to launch 50 peanut candies in 60 seconds into a target container.NASA/JPL-Caltech More points were awarded for successfully landing the candy into the highest, smallest level of the triangular Plexiglas target — not an easy task.NASA/JPL-Caltech Treats went flying through the air by the dozens at the annual Invention Challenge at NASA’s Jet Propulsion Laboratory.
The 25th Invention Challenge at NASA’s Jet Propulsion Laboratory in Southern California, which welcomed more than 200 students to compete using home-built devices, was pretty sweet this year. Literally.
That’s because the challenge at the Friday, Dec. 6, competition was to construct an automated machine that would launch, within 60 seconds, 50 chocolate-coated-peanut candies over a barrier and into a triangular Plexiglas container 16 feet (5 meters) away. The mood was tense as teachers, parents, and JPL employees watched the “Peanut Candy Toss Contest” from the sidelines, some of them eating the ammunition.
Students on 21 teams from Los Angeles and Orange county middle and high schools turned to catapults, slingshots, flywheels, springs, and massive rubber bands. There was lots of PVC piping. A giant device shaped like a blue bunny shot candy out of its nose with the help of an air compressor, while other entries relied on leaf blowers and vacuums.
A team from Santa Monica High School won the 2024 Invention Challenge at JPL on Dec. 6 with a device was based on a crossbow.NASA/JPL-Caltech Some were more successful than others. Ultimately, it was an old-school design that won first place for a team from Santa Monica High School: a modified crossbow.
“I tried to come up with something that was historically tried and true,” said Steele Winterer, a senior on the team who produced the initial design. Like his teammates, Steele is in the school’s engineering program and helped build the device during class. He described the process as “nerve-wracking,” “messy,” and “disorganized,” but everyone found their role as the design was refined.
Second and third place went to teams from Oakwood School in North Hollywood, which both took a firing-line approach, using four parallel wooden devices, with one student per device firing after each other in quick succession.
Two regional Invention Challenges held at Costa Mesa High School and Augustus Hawkins High School in South L.A. last month had winnowed the field to the 21 teams invited to the final event at JPL. At the finals, three JPL-sponsored teams from out-of-state schools and two teams that included adult engineers faced off in a parallel competition. In this second competition group, retired JPL engineer Alan DeVault took first place, followed by Boston Charter School of Science coming in second, and Centaurus High School from Colorado in third.
Competing with a wooden device at the 2024 Invention Challenge, retired JPL engineer and longtime participant Alan DeVault won first place among JPL-sponsored teams, which included professionals and out-of-state students. Challenge organizer Paul MacNeal kneels at right.NASA/JPL-Caltech Held since 1998 (with a two-year break during the COVID-19 pandemic), the contest was designed by JPL mechanical engineer Paul MacNeal to inspire students to discover a love for building things and solving problems. Student teams spend months designing, constructing, and testing their devices to try to win the new challenge that MacNeal comes up with each year.
“When student teams come to the finals, they are engaged just as engineers are engaged in the work we do here at JPL,” MacNeal said. “It’s engineering for the joy of it. It’s problem-solving but it’s also team building. And it’s unique because the rules change every year. The student teams get to see JPL engineering teams compete side by side. I started this contest to show students that engineering is fun!”
The event is supported by dozens of volunteers from JPL, which is managed by Caltech in Pasadena for NASA.

JPL Director Laurie Leshin, flanked by a model of the Voyager spacecraft and an image of Ed Stone, addresses the audience during the unveiling of the Dr. Edward Stone Exploration Trail on Dec. 6, 2024, at the lab. Ed Stone Memorial Plaque Dedication Ceremony Requester: Susie Woodall Date: 06-DEC-2024 Photographer: Ryan Lannom A series of plaques stretching through the heart of the agency’s Jet Propulsion Laboratory offers highlights of the space explorer’s career and the Voyager mission he led.
Family members, colleagues, and local dignitaries gathered on Friday, Dec. 6, at NASA’s Jet Propulsion Laboratory in Southern California for the unveiling of a memorial honoring Ed Stone, best known as the longtime project scientist of the agency’s Voyager mission. Stone died in June 2024 at age 88 after leading the mission for half a century and leading JPL for a decade.
Stretching through the heart of the lab, the Dr. Edward Stone Exploration Trail traces the arc of Stone’s distinguished career and the long journeys of the twin Voyager space probes. Designed with simple line drawings, 24 disc-shaped plaques along the trail offer career and mission highlights while evoking the Golden Record aboard both spacecraft.
The Dr. Edward Stone Exploration Trail begins in front of the building where Stone served as JPL’s director. NASA/JPL-Caltech Launched in the summer of 1977, Voyager 1 and 2 have since traveled more than 15.4 billion and 12.9 billion miles (24 billion and 20 billion kilometers), respectively — farther than any other human-made object. The plaques trace their trajectories to Jupiter and Saturn as well as their diverging paths, with Voyager 2 heading toward Uranus and Neptune as Voyager 1 made a beeline for interstellar space. Other stops along the trail honor Stone’s work creating the W.M. Keck Observatory in 1985, his appointment as JPL’s director in 1991, and his being honored with the Distinguished Service Award 2013.
“To follow in the footsteps of Ed Stone is to walk the path of an extraordinary person who dedicated his time on Earth to reaching for the stars, and who paved the way for others to do the same,” said Laurie Leshin, director of JPL. “This trail is a testament to Ed’s bold curiosity, visionary leadership, and passion for science that have enabled us to explore farther into the cosmos than ever before. It’s also a reminder of his influence on so many of our endeavors to reach new frontiers in space.”
Embedded in the pavement, 24 additional plaques trace the approximate trajectories of the Voyager spacecraft. The shape and design language of the plaques evoke the design of the Gold Record.NASA/JPL-Caltech Blazing a Trail
Stone’s penchant for walking was one of the topics that came up when members of JPL’s Office of the Director, its DesignLab, and the Voyager team began discussing ways to honor his outsize contributions to JPL and science. From those initial brainstorming sessions came the question, “How can we do something to memorialize him at JPL that gets people to walk?” recalled DesignLab’s graphic manager, Lauren Shapiro.
The distances between the plaques are roughly proportional the distances between the events they highlight, and the team even tried to make flight trajectories of the probes as accurate as possible, given the challenges of avoiding buildings and the like.
Designer Kaelyn Richards relied on the Voyager Golden Record as a guide for the visual language. “I referenced a lot of old scientific diagrams that were made by artists in the ’70s and ’80s, and I used a solar system modeling program to show the exact position of the planets on the day that the ‘Pale Blue Dot’ was taken,” she said, referring to the plaque honoring the famous 1990 image Voyager 1 took of Earth from beyond Neptune.
“Everyone seemed to agree that Voyager was Ed Stone. Yes, he did so much more, but this was really his biggest legacy,” Shapiro said. “So we’re honoring both the mission and the person alongside each other. And they both, in a poetic way, have had very long, incredible lives.”
Voyager 1 and 2 both carry the Golden Record, a 12-inch gold-plated copper disk intended to communicate a story of our world to extraterrestrials with sounds and images that portray the diversity of life and culture on Earth. NASA/JPL-Caltech After retiring as Voyager’s project scientist, Stone returned to teaching and research at Caltech, which manages JPL for NASA.
Before attending the unveiling, Caltech President Thomas Rosenbaum said, “Ed was a whirlwind of activity. I have many good memories of running after Ed in the midst of conversation as he charged across campus. Ed’s ambition, drive, and vision were accompanied by his warmth, humility, and commitment to Caltech and our students. He served as a mentor for generations of scholars who have gone on to be leaders in their fields. He conveyed a curiosity and a thirst for discovery that inspired.”
Stone had joined the Caltech faculty as an assistant professor in 1967 and, from 1983 to 1988, chaired the Division of Physics, Mathematics and Astronomy. He went on to serve as vice president for astronomical facilities from 1988 to 1990 and as vice provost for special projects from 2004 to 2022. In 2023, Caltech established a new faculty position, the Edward C. Stone Professorship.
But there was another academic honor that Stone also cherished: the 2012 naming of the Edward Stone Middle School in his hometown of Burlington, Iowa. A short walk from the plaque marking that milestone is the final stop of the Exploration Trail, its simple inscription reading: “Ed Stone’s leadership and pursuit of scientific knowledge expanded humanity’s understanding of the universe. His legacy lives on through the Voyager mission, and the countless people he has inspired.”
