Meet the Johnson CLPS Team Supporting NASA’s Lunar Exploration Goals

[NASA]

As part of NASA’s Artemis campaign, the Commercial Lunar Payload Services (CLPS) initiative, managed out of Johnson Space Center in Houston, is paving the way for conducting lunar science for the benefit of humanity.

Through CLPS, NASA teams worked closely with commercial companies to develop a new model for space exploration, enabling a sustainable return to the Moon. These commercial missions deliver NASA science and technology to the lunar surface, providing insights into the environment and demonstrating new technologies that will support future astronauts—on the Moon and, eventually, on Mars.

Carrying a suite of NASA science and technology, Firefly Aerospace’s Blue Ghost Mission 1 successfully landed at 3:34 a.m. EST on Sunday, March 2, 2025, near a volcanic feature called Mons Latreille within Mare Crisium, a more than 300-mile-wide basin located in the northeast quadrant of the Moon’s near side.

2025: A Year of Lunar Firsts

This year has already seen historic milestones. Firefly Aerospace’s Blue Ghost Mission 1 successfully delivered 10 science and technology instruments to the Moon on March 2, 2025. It touched down near a volcanic feature called Mons Latreille within Mare Crisium, a basin over 300 miles wide in the northeast quadrant of the Moon’s near side. Intuitive Machines’ IM-2 Mission, landed near the Moon’s South Pole on March 6, marking the southernmost lunar landing ever achieved.

The lunar deliveries for NASA have collected valuable insights and data to inform the next giant leap in humanity’s return to the Moon, helping scientists address challenges like lunar dust mitigation, resource utilization, and radiation tolerance.

Mark Dillard, Blue Ghost Mission 1 payload integration manager, has been at the forefront of space exploration for more than 40 years, including 28 years with the International Space Station Program. Beyond ensuring all NASA payloads are integrated onto the lunar landers, he oversees schedules, costs, and technical oversight while fostering strong partnerships with CLPS vendors and NASA science teams.

“I believe NASA is about to enter its next Golden Age,” said Dillard. “The enthusiasm of Firefly’s engineering team is contagious, and it has been a privilege to witness their success.”

Dillard’s career includes five years as NASA’s resident manager in Torino, Italy, where he oversaw the development of International Space Station modules, including three logistics modules, the European Space Agency’s Columbus module, and two space station nodes.

“Like Apollo, Shuttle, and the International Space Station Programs, Artemis will add the next building block for space exploration,” said Dillard. “The CLPS initiative is a significant building block, aiming to establish reliable and long-term access to the lunar surface.”

Susan Lederer: Guiding Science in Real Time

Susan Lederer, IM-2 project scientist, has spent years ensuring all the NASA instruments are fully prepared for lunar operations. She oversees real-time science operations from IM’s Nova Control Center, working to maximize the mission’s scientific return and prepare for the next generation of astronauts to explore the Moon, Mars, and beyond.

“We have done our best with remote data, but the only way to truly understand the Moon—how to drill for resources, how to live on another celestial body—is to go there and do the experiments,” she said. “Now, we get to do that.”

Lederer’s path to CLPS was shaped by a background in space exploration, astrophysics, and planetary science. She has contributed to multiple spacecraft missions, including NASA’s Deep Impact mission, which sent a projectile into Comet Tempel 1, and a separate mission that retrieved a sample from asteroid Itokawa.

On Ascension Island, a remote joint U.S. Air Force and Royal Air Force base, she co-led the construction of a 20,000-pound optical telescope to study space debris. Her work spans collaborations with the Defense Advanced Research Projects Agency, a tenure as a physics professor, and the design of impact experiments at NASA’s Experimental Impact Lab, where she used a vertical gun firing projectiles at speeds exceeding those of sniper rifles to study asteroid and comet collisions.

Lederer has logged hundreds of hours conducting observing runs at professional observatories worldwide, where she refined both her scientific precision and her ability to repair instruments while working alone on remote mountaintops.

As a private pilot and SciComm (the science equivalent of Capsule Communicator) for NASA’s Desert Research and Technology Studies, she honed her mission communication skills. She was also part of an international team that discovered two extrasolar planetary systems—one with a single Earth-sized planet and another with seven—orbiting ultracool red dwarf stars.

Her expertise has uniquely prepared her to oversee real-time science operations for lunar missions in high-intensity environments.

Lederer emphasizes the importance of both scientific discovery and the practical realities of living and working on another world—a challenge NASA is tackling for the first time in history.

“Honestly, it’s when things don’t go as planned that you learn the most,” she said. “I’m looking forward to the surprises that we get to solve together as a team. That’s our greatest strength—the knowledge and teamwork that make this all happen.”

Lederer credits the success of CLPS lunar deliveries to the dedication of teams working on payloads like Polar Resources Ice Mining Experiment-1 and Lunar Retroreflector Array, as well as peers within NASA’s Science Mission Directorate, Space Technology Mission Directorate, and Intuitive Machines.

“What we do every day in CLPS creates a new world for exploration that is efficient in schedule, cost, and gaining science and technology knowledge in these areas like we’ve never done before,” said Lederer. “It feels very much like being a trailblazer for inspiring future generations of explorers – at least that’s my hope, to keep the next generation inspired and engaged in the wonders of our universe.”
