NASA has awarded Firefly Aerospace of Cedar Park, Texas, $176.7 million to deliver two rovers and three scientific instruments to the lunar surface as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign to explore more of the Moon than ever before.

This delivery is the first time NASA will use multiple rovers and a variety of stationary instruments, in a collaborative effort with the CSA (Canadian Space Agency) and the University of Bern, to help us understand the chemical composition of the lunar South Pole region and discover the potential for using resources available in permanently shadowed regions of the Moon.

“Through CLPS, NASA is embracing a new era of lunar exploration, with commercial companies leading the way,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “These investigations will produce critical knowledge required for long-term sustainability and contribute to a deeper understanding of the lunar surface, allowing us to meet our scientific and exploration goals for the South Pole region of the Moon for the benefit of all.”

Under the new CLPS task order, Firefly is tasked with delivering end-to-end payload services to the lunar surface, with a period of performance from Tuesday to March 29, 2030. The company’s lunar lander is targeted to land at the Moon’s South Pole region in 2029.

This is Firefly’s fifth task order award and fourth lunar mission through CLPS. Firefly’s first delivery successfully landed on the Moon’s near side in March 2025 with 10 NASA payloads. The company’s second mission, targeting a launch in 2026, includes a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side. Firefly’s third lunar mission will target landing in the Gruithuisen Domes on the near side of the Moon in 2028, delivering six experiments to study that enigmatic lunar volcanic terrain.

“As NASA sends both humans and robots to further explore the Moon, CLPS deliveries to the lunar South Pole region will provide a better understanding of the exploration environment, accelerating progress toward establishing a long-term human presence on the Moon, as well as eventual human missions to Mars,” said Adam Schlesinger, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston.

The rovers and instruments that are part of this newly awarded flight include:

  • MoonRanger is an autonomous microrover that will explore the lunar surface. MoonRanger will collect images and telemetry data while demonstrating autonomous capabilities for lunar polar exploration. Its onboard Neutron Spectrometer System instrument will study hydrogen-bearing volatiles and the composition of lunar regolith, or soil.
    Lead development organizations: NASA’s Ames Research Center in California’s Silicon Valley, and Carnegie Mellon University and Astrobotic, both in Pittsburgh.
  • Stereo Cameras for Lunar Plume Surface Studies will use enhanced stereo imaging photogrammetry, active illumination, and ejecta impact detection sensors to capture the impact of the rocket exhaust plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will help predict lunar regolith erosion and ejecta characteristics, as bigger, heavier spacecraft and hardware are delivered to the Moon near each other in the future.
    Lead development organization: NASA’s Langley Research Center in Hampton, Virginia. 
  • Laser Retroreflector Array is an array of eight retroreflectors on an aluminum support structure that enables precision laser ranging, a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The array is a passive optical instrument, which functions without power, and will serve as a permanent location marker on the Moon for decades to come.
    Lead development organization: NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
  • A CSA Rover is designed to access and explore remote South Pole areas of interest, including permanently shadowed regions, and to survive at least one lunar night. The CSA rover has stereo cameras, a neutron spectrometer, two imagers (visible to near-infrared), a radiation micro-dosimeter, and a NASA-contributed thermal imaging radiometer developed by the Applied Physics Laboratory. These instruments will advance our understanding of the physical and chemical properties of the lunar surface, the geological history of the Moon, and potential resources such as water ice. It will also improve our understanding of the environmental challenges that await future astronauts and their life support systems.
    Lead development organization: CSA.
  • Laser Ionization Mass Spectrometer is a mass spectrometer that will analyze the element and isotope composition of lunar regolith. The instrument will utilize a Firefly-built robotic arm and Titanium shovel that will deploy to the lunar surface and support regolith excavation. The system will then funnel the sample into its collection unit and use a pulsed laser beam to identify differences in chemistry compared to samples studied in the past, like those collected during the Apollo program. Grain-by-grain analyses will provide a better understanding of the chemical complexity of the landing site and the surrounding area, offering insights into the evolution of the Moon.
    Lead development organization: University of Bern in Switzerland.

Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon, and to support human exploration beyond to Mars. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.

Curiosity Blog, Sols 4609–4610: Recharged and Ready To Roll Onwards

Curiosity Blog, Sols 4609–4610: Recharged and Ready To Roll Onwards

A grayscale photo from the Martian surface shows rough, slightly uneven, dark gray, rocky terrain extending to a plateau that rises in the distance, at the top of the frame. In the foreground, many smaller rocks are poking above the surface, much lighter-toned than the surrounding ground, looking like white specks on the surface.
NASA’s Mars rover Curiosity acquired this image showing the boxwork hollow where it is investigating, and the boxwork ridge on the far side of the hollow, using its Left Navigation Camera. Curiosity captured the image on July 20, 2025 — Sol 4605, or Martian day 4,605 of the Mars Science Laboratory mission — at 18:51:55 UTC.

Earth planning date: Wednesday, July 23, 2025

For today’s planning, we were in the same workspace as the Monday plan — on purpose! We don’t often have a plan without a drive but in order to allow the battery to recover from some power-hungry SAM atmospheric measurements over the weekend and on Monday, we needed to stay put and skip our usual drive. As a result, we gained a bonus planning cycle at this interesting workspace. 

We are in one of the “hollows” between the resistant ridges of the “boxwork” terrain, as you can see in the image for this blog. This made for a quieter Operations day for me as the APXS planner. As Deborah noted in Monday’s blog, we have already gotten three APXS and MAHLI measurements in this workspace, so we didn’t acquire more in this plan.

This morning, we focused on documenting some small light-toned, rounded, white pebbles in the workspace (you can see them in the accompanying Navcam image), which look very different from the underlying bedrock. We used our one ChemCam LIBS analysis for the plan on “Yana Qaqa.” Mastcam will image this pebble, another at “Ojos del Salado,” and a really cool-looking target with a dendritic-looking texture at “Punta de Lobos.”

Further afield, Mastcam will image the adjacent boxwork ridge and hollow in our drive direction, and a series of troughs with raised edges to the right of our current workspace. ChemCam will image a long-distance RMI mosaic of “Cueva de los Vencejos y Murciélagos,” which was imaged by Mastcam on Monday, and also acquire some further images of the “Mishe Mokwa” hill.

We had a bumper couple of sols of atmospheric measurements over the weekend and Monday. Now we revert back to our more normal environmental and atmospheric monitoring. These do not get as much attention sometimes as the amazing images we take of the fascinating rocks we see, but have been taking place consistently and continuously since Curiosity’s landing almost 13 years ago now. This plan includes a series of Navcam movies (suprahorizon, dust devil) and a line-of-sight observation of dust, standard REMS and DAN observations, and two Mastcam tau measurements, looking at dust in the atmosphere.

Our 24-meter drive (almost 79 feet) will take us out of this hollow and back up on top of a ridge. From here, we hope to be able to spy the best driving path through the boxwork. The ridges are up to 5 meters in diameter (about 16 feet), so we are cautiously hopeful that we can just trundle along one of the ridges as we investigate this fascinating terrain.

Hubble Spies Swirling Spiral

A spiral galaxy with a disk made of several swirling arms. Patchy blue clouds of gas speckle the disk where stars are forming and lighting the gas around them. The core of the galaxy is large and shines brightly gold, while the spiral arms are a paler and faint reddish color. Neighboring galaxies – from small, elongated spots to larger swirling spirals – are visible across the black background.
The NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 3285B, a member of the Hydra I cluster of galaxies.
ESA/Hubble & NASA, R. J. Foley (UC Santa Cruz)

The swirling spiral galaxy in this NASA/ESA Hubble Space Telescope image is NGC 3285B, which resides 137 million light-years away in the constellation Hydra (the Water Snake). Hydra has the largest area of the 88 constellations that cover the entire sky in a celestial patchwork. It’s also the longest constellation, stretching 100 degrees across the sky. It would take nearly 200 full moons, placed side by side, to reach from one side of the constellation to the other.

NGC 3285B is a member of the Hydra I cluster, one of the largest galaxy clusters in the nearby universe. Galaxy clusters are collections of hundreds to thousands of galaxies bound to one another by gravity. The Hydra I cluster is anchored by two giant elliptical galaxies at its center. Each of these galaxies is about 150,000 light-years across, making them about 50% larger than our home galaxy, the Milky Way.

NGC 3285B sits on the outskirts of its home cluster, far from the massive galaxies at the center. This galaxy drew Hubble’s attention because it hosted a Type Ia supernova in 2023. Type Ia supernovae happen when a type of condensed stellar core called a white dwarf detonates, igniting a sudden burst of nuclear fusion that briefly shines about 5 billion times brighter than the Sun. The supernova, named SN 2023xqm, is visible here as a blueish dot on the left edge of the galaxy’s disk.

Hubble observed NGC 3285B as part of an observing program that targeted 100 Type Ia supernovae. By viewing each of these supernovae in ultraviolet, optical, and near-infrared light, researchers aim to disentangle the effects of distance and dust, both of which can make a supernova appear redder than it actually is. This program will help refine cosmic distance measurements that rely on observations of Type Ia supernovae.

This is how I make a difference — by protecting the land, the community, and hopefully inspiring others to do the same.

Melissa John

Melissa John

Sustainability Program Lead

Through awareness campaigns and outreach events, John empowers employees to be mindful of their environmental impact. Whether she is fostering grassroots connections, leading hands-on events, or recognizing colleagues who prioritize climate-aware actions, John remains dedicated to making a lasting, positive impact on the planet. 

John credits her Diné heritage and cultural values for fueling her passion to protect and preserve Earth for future generations. 

John began her NASA career at White Sands as a document specialist, reviewing schedules and environmental reports. She later transitioned into technical editing and gradually got involved in green initiatives, volunteering her time before eventually stepping into her current leadership role. 

Now, she coordinates a sitewide working group dedicated to reducing the facility’s environmental impact and inspires others to think critically about everyday actions and their ripple effects. 

A woman sits on a bench with an embroidered blanket placed in front of her.

John did not always know how she would make her mark. 

“Growing up, I remember a teacher asking how we could make a difference in the world,” she said. “I never forgot that question.” 

During the years she spent working in accounting and in the mining industry, she kept returning to that question. It was not until she joined NASA that she found her answer: 

“This — this is how I make my difference in the world.” 

The work also helped John grow in ways she did not expect. 

“I was painfully shy as a kid and terrified of speaking in front of a crowd,” she said. “But when I took on this role, I knew I had to find my voice. I still have timid moments, but the pride I feel in this work helps me push through. I’ve been through a lot, but I’m still here learning, growing, and showing up for the team I now call family.” 

John credits her strong support system for that transformation. “I am in awe of the women I’ve worked with,” she said. “I hope I can inspire others as they have inspired me.” 

From left to right: Mary Canavan, Melissa John, Amanda Skarsgard, and Pam Egan at the annual Plant Fair Share at White Sands Test Facility.

Whether on Earth or beyond it, John believes that thoughtful action today leads to a brighter tomorrow. She is committed to leaving the world a better place for the next generation. Her legacy is simple: “Clean air, clean water, and clean land — that’s what I want to pass on.”

Celebrating 25 Years of Continuous Human Presence Aboard the International Space Station 

GMT198_16_39_Jonny Kim_Deferred Release Attn. Dylan Mathis for 25th Anniversary Cupola Photo
NASA/Jonny Kim

NASA and its partners have supported humans continuously living and working in space since November 2000. A truly global endeavor, the International Space Station has been visited by more than 280 people from 23 countries and a variety of international and commercial spacecraft. The unique microgravity laboratory has hosted more than 4,000 experiments from more than 5,000 researchers in more than 110 countries. The space station also is facilitating the growth of a commercial market in low Earth orbit for research, technology development, and crew and cargo transportation.

NASA created a dedicated logo to symbolize this historic achievement. The logo is visible in the cupola of the space station in this July 17, 2025, image. The central astronaut figure is representative of all those who have lived and worked aboard the station during the 25 years of continuous human presence. In the dark sky of space surrounding the astronaut are 15 stars, which symbolize the 15 partner nations that support the orbiting laboratory.

There is a visual representation of the space station toward the edge of the design, where humans have had a continuous presence for the past 25 years. The Earth represents the planet which the station orbits and that science conducted aboard the orbiting laboratory is for the benefit of all. Integrated into the border of the design is the number “25” to further represent the 25 years of human presence aboard the space station.

After 25 years of continuous human presence, the space station remains a training and proving ground for deep space missions, enabling NASA to focus on Artemis missions to the Moon and Mars.
