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

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.

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.

Meet the Johnson employees contributing to lunar innovations that are helping to shape the future of human presence on the Moon.

Mark Dillard: Pioneering Payload Integration

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.”

Blood Moon Lunar Eclipse

The phases of the lunar eclipse are visible in this time-lapse image of the Moon above the Space Environments Complex at NASA’s Glenn Research Center at NASA’s Neil Armstrong Test Facility in Sandusky, OH on March 14, 2025.

Toward the middle of the Moon’s track through the sky, it appears red – this is the Blood Moon. One meaning of a “Blood Moon” is based on its red glow. This blood moon occurs during a total lunar eclipse. During a total lunar eclipse, Earth lines up between the Moon and the Sun, hiding the Moon from sunlight. When this happens, the only light that reaches the Moon’s surface is from the edges of the Earth’s atmosphere. The air molecules from Earth’s atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon’s surface with a red glow, making the Moon appear red in the night sky.

NASA Data Supports Everglades Restoration

This story is the second installment of a series on NASA’s mission to measure greenhouse gases in Florida’s mangrove ecosystem. Read the first part here.

Along the southernmost rim of the Florida Peninsula, the arching prop roots of red mangroves line the coast. Where they dip below the water’s surface, fish lay their eggs, using the protection from predators that the trees provide. Among their branches, wading birds like the great blue heron and the roseate spoonbill find rookeries to rear their young. The tangled matrix of roots collects organic matter and ocean-bound sediments, adding little by little to the coastline and shielding inland biology from the erosive force of the sea.

In these ways, mangroves are equal parts products and engineers of their environment. But their ecological value extends far beyond the coastline. 

Tropical wetlands absorb carbon dioxide (CO2) from the atmosphere with impressive efficiency. Current estimates suggest they sequester carbon dioxide 10 times faster and store up to five times more carbon than old-growth forests. But as part of the ever-changing line between land and sea, coastal wetlands are vulnerable to disturbances like sea level rise, hurricanes, and changes in ocean salinity. As these threats intensify, Florida’s wetlands — and their role as a critical sink for carbon dioxide — face an uncertain future.

A new data product developed by NASA-funded researchers will help monitor from space the changing relationship between coastal wetlands and atmospheric carbon. It will deliver daily measurements of gaseous flux — the rate at which gas is exchanged between the planet’s surface and atmosphere. The goal is to improve local and global estimates of carbon dioxide levels and help stakeholders evaluate wetland restoration efforts.

NASA measures carbon dioxide from ground, air and space

In the Everglades, flux measurements have historically relied on data from a handful of “flux towers.” The first of these towers was erected in June 2003, not far from the edge of Shark River at a research site known as SRS-6. A short walk from the riverbank, across a snaking path of rain-weathered, wooden planks, sits a small platform where the tower is anchored to the forest floor. Nearly 65 feet above the platform, a suite of instruments continuously measures wind velocity, temperature, humidity, and concentrations of atmospheric gases. These measurements are used to quantify the amount of carbon dioxide that wetland vegetation removes from the atmosphere — and the amount of methane released.

“Hundreds of research papers have come from this site,” said David Lagomasino, a professor of coastal ecology at East Carolina University. The abundance of research born from SRS-6 underscores its scientific value. But the BlueFlux campaign is committed to detailing flux across a much larger area — to fill in the gaps between the towers.

Part of NASA’s new greenhouse-gas product is a machine-learning model that estimates gaseous flux using observations made by the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Aqua and Terra satellites. The MODIS instruments capture images and data of South Florida every one to two days, measuring the wavelength of sunlight reflected by the planet’s surface to produce a dataset called surface spectral reflectance.

Different surfaces — like water, vegetation, sand, or decaying organic matter — reflect different wavelengths of light. With the help of some advanced statistical algorithms, modelers can use these measurements to generate a grid of real-time flux data.

To help ensure the satellite-based model is making accurate predictions, researchers compare its outputs to measurements made on the ground. But with only a handful of flux towers in the region, ground-based flux data can be hard to come by.

To augment existing datasets, NASA researchers use a relatively new airborne technique for measuring flux. Since April 2022, NASA’s airborne science team has conducted 34 flights equipped with a payload known colloquially as “CARAFE,” short for the CARbon Airborne Flux Experiment. The CARAFE instrument measures concentrations of methane, carbon dioxide, and water vapor, generating readings that researchers combine with information about the plane’s speed and orientation to estimate rates of gaseous flux at fixed points along each flight’s path.

“This is one of the first times an instrument like this has flown over a mangrove forest anywhere in the world,” said Lola Fatoyinbo, a forest ecologist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Early findings from space-based flux data confirm that, in addition to acting as a sink of carbon dioxide, tropical wetlands are a significant source of methane — a greenhouse gas that traps heat roughly 80 times more efficiently than carbon dioxide. In fact, researchers estimate that Florida’s entire wetland expanse produces enough methane to offset the benefits of wetland carbon removal by about 5%.

“There are also significant differences in fluxes between healthy mangroves and degraded ones,” Fatoyinbo said. In areas where mangrove forests are suffering, say after a major hurricane, “you end up with more greenhouse gases in the atmosphere.” As wetland ecology responds to intensifying natural and human pressures, the data product will help researchers precisely monitor the impact of ecological changes on global carbon dioxide and methane levels.

‘We need this reliable science’

The Everglades today are roughly half their original size — primarily the result of a century’s worth of uninterrupted land development and wetland drainage projects. It’s difficult to quantify the impact of wetland losses at this scale. Florida’s tropical wetlands aren’t just an important reminder of the beauty and richness of the state’s natural history. They’re also a critical reservoir of atmospheric carbon and a source of drinking water for millions of South Florida residents.

“We know how valuable the wetlands are, but we need this reliable science to help translate their benefits into something that can reach people and policymakers,” said Steve Davis, chief science officer for the Everglades Foundation, a non-profit organization in Miami-Dade County that provides scientific research and advocacy in an effort to protect and restore the Everglades.

As new policies and infrastructure are designed to support Everglades restoration, researchers hope NASA’s daily flux product will help local officials evaluate their restoration efforts in real time — and adjust the course as needed.

The prototype of the product, called Daily Flux Predictions for South Florida, is slated for release this year and will be available through NASA’s Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).

Hubble Sees a Spiral and a Star

This NASA/ESA Hubble Space Telescope image features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart. The star, marked with four long diffraction spikes, is in our own galaxy. It’s just 7,109 light-years away from Earth. The galaxy, named NGC 4900, lies about 45 million light-years from Earth.

This image combines data from two of Hubble’s instruments: the Advanced Camera for Surveys, installed in 2002 and still in operation today, and the older Wide Field and Planetary Camera 2, which was in use from 1993 to 2009. The data used here were taken more than 20 years apart for two different observing programs — a real testament to Hubble’s long scientific lifetime!

Both programs aimed to understand the demise of massive stars. In one, researchers studied the sites of past supernovae, aiming to estimate the masses of the stars that exploded and investigate how supernovae interact with their surroundings. They selected NGC 4900 for the study because it hosted a supernova named SN 1999br.

In the other program, researchers laid the groundwork for studying future supernovae by collecting images of more than 150 nearby galaxies. When researchers detect a supernova in one of these galaxies, they can refer to these images, examining the star at the location of the supernova. Identifying a supernova progenitor star in pre-explosion images gives valuable information about how, when, and why supernovae occur.
