Acting NASA Administrator Janet Petro and Anke Kaysser-Pyzalla, chair, Executive Board, DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt), signed an agreement June 16, 2025, to continue a partnership on space medicine research. With this agreement, DLR will provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.Credit: DLR While attending the Paris Air Show June 16, NASA acting Administrator Janet Petro signed an agreement with DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt) to continue a partnership in space medicine research. This renewed collaboration builds on previous radiation mitigation efforts for human spaceflight. As NASA advances the Trump-Vance Administration’s goals for exploration on the Moon and Mars, minimizing exposure to space radiation is one of the key areas the agency is working to protect crew on long duration missions.
With this agreement, DLR will leverage its human spaceflight expertise and provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission, building on previous work in this area during the Artemis I mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.
“In keeping with the historic agreements NASA has made with international partners as a part of Artemis, I am pleased to sign a new NASA-DLR joint agreement today, to enable radiation research aboard Artemis II,” said acting NASA Administrator Janet Petro. “The German Aerospace Center has been a valuable partner in Artemis, having previously worked with NASA to test technology critical to our understanding of radiation on humans aboard an Orion spacecraft on Artemis I and providing a CubeSat as part of Artemis II. Following a productive meeting between President Trump and German Chancellor Merz earlier this month, I am excited to build upon our great partnership with Germany.”
During the Artemis II mission’s planned 10-day journey around the Moon and back, four of DLR’s newly developed M-42 extended (M-42 EXT) radiation detectors will be on board, contributing vital data to support astronaut safety. This next-generation device represents a new phase of research as NASA and DLR continue working together to safeguard human health in space.
Under the leadership of President Trump, America’s Artemis campaign has reignited NASA’s ambition, sparking international cooperation and cutting-edge innovation. The continued partnership with DLR and the deployment of their advanced M-42 EXT radiation detectors aboard Artemis II exemplifies how the Trump-Vance Administration is leading a Golden Era of Exploration and Innovation that puts American astronauts on the path to the Moon, Mars, and beyond.
“To develop effective protective measures against the impact of space radiation on the human body, comprehensive and coherent radiation measurements in open space are essential,” says Anke Pagels-Kerp, divisional board member for space at DLR. “At the end of 2022, Artemis I carried 12,000 passive and 16 active detectors inside the Helga and Zohar mannequins, which flew aboard the Orion spacecraft as part of DLR’s MARE project. These provided a valuable dataset – the first continuous radiation measurements ever recorded beyond low Earth orbit. We are now excited to take the next step together with NASA and send our upgraded radiation detectors around the Moon on the Artemis II mission.”
Through the Artemis campaign, the agency will establish a long-term presence on the Moon for scientific exploration with our commercial and international partners, learn how to live and work away from home, and prepare for future human exploration of Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Instruments in space are helping scientists map wastewater plumes flowing into the Pacific Ocean from the heavily polluted Tijuana River, seen here with the San Diego sky-line to the north. NOAA Proof-of-concept results from the mouth of the Tijuana River in San Diego County show how an instrument called EMIT could aid wastewater detection.
An instrument built at NASA’s Jet Propulsion Laboratory to map minerals on Earth is now revealing clues about water quality. A recent study found that EMIT (Earth Surface Mineral Dust Source Investigation) was able to identify signs of sewage in the water at a Southern California beach.
The authors of the study examined a large wastewater plume at the mouth of the Tijuana River, south of Imperial Beach near San Diego. Every year, millions of gallons of treated and untreated sewage enter the river, which carries pollutants through communities and a national reserve on the U.S.-Mexico border before emptying into the Pacific Ocean. Contaminated coastal waters have been known to impact human health — from beachgoers to U.S. Navy trainees — and harm marine ecosystems, fisheries, and wildlife.
For decades scientists have tracked water quality issues like harmful algal blooms using satellite instruments that analyze ocean color. Shades that range from vibrant red to bright green can reveal the presence of algae and phytoplankton. But other pollutants and harmful bacteria are more difficult to monitor because they’re harder to distinguish with traditional satellite sensors.
A plume spreads out to sea in this image captured off San Diego by the Sentinel-2 satellite on March 24, 2023. Both a spectroradiometer used to analyze water samples (yellow star) and NASA’s EMIT identified in the plume signs of a type of bacterium that can sicken humans and animals.SDSU/Eva Scrivner That’s where EMIT comes in. NASA’s hyperspectral instrument orbits Earth aboard the International Space Station, observing sunlight reflecting off the planet below. Its advanced optical components split the visible and infrared wavelengths into hundreds of color bands. By analyzing each satellite scene pixel by pixel at finer spatial resolution, scientists can discern what molecules are present based on their unique spectral “fingerprint.”
Scientists compared EMIT’s observations of the Tijuana River plume with water samples they tested on the ground. Both EMIT and the ground-based instruments detected a spectral fingerprint pointing to phycocyanin, a pigment in cyanobacteria, an organism that can sicken humans and animals that ingest or inhale it.
‘Smoking Gun’
Many beachgoers are already familiar with online water-quality dashboards, which often rely on samples collected in the field, said Christine Lee, a scientist at JPL in Southern California and a coauthor of the study. She noted the potential for EMIT to complement these efforts.
“From orbit you are able to look down and see that a wastewater plume is extending into places you haven’t sampled,” Lee said. “It’s like a diagnostic at the doctor’s office that tells you, ‘Hey, let’s take a closer look at this.’”
Lead author Eva Scrivner, a doctoral student at the University of Connecticut, said that the findings “show a ‘smoking gun’ of sorts for wastewater in the Tijuana River plume.” Scrivner, who led the study while at San Diego State University, added that EMIT could be useful for filling data gaps around intensely polluted sites where traditional water sampling takes a lot of time and money.
EMIT’s Many Uses
The technology behind EMIT is called imaging spectroscopy, which was pioneered at JPL in the 1980s. Imaging spectrometers developed at JPL over the decades have been used to support areas ranging from agriculture to forest health and firefighting.
When EMIT was launched in July 2022, it was solely aimed at mapping minerals and dust in Earth’s desert regions. That same sensitivity enabled it to spot the phycocyanin pigments off the California coast.
Scrivner hadn’t anticipated that an instrument initially devoted to exploring land could reveal insights about water. “The fact that EMIT’s findings over the coast are consistent with measurements in the field is compelling to water scientists,” she said. “It’s really exciting.”

Sols 4559-4560: Drill Campaign — Searching for a Boxwork Bedrock Drill Site
NASA’s Mars rover Curiosity acquired this image of a portion of its workspace, full of interesting but not drillable bedrock, using its Left Navigation Camera on June 2, 2025 — Sol 4558, or Martian day 4,558 of the Mars Science Laboratory mission — at 12:23:24 UTC. NASA/JPL-Caltech Written by Lucy Lim, Planetary Scientist at NASA’s Goddard Space Flight Center
Earth planning date: Monday, June 2, 2025
Now that Curiosity has spent a few sols collecting close-up measurements of the rocks in the outer edge of the boxwork-forming geologic unit, the team has decided that it’s time to collect a drill sample. The geochemical measurements by APXS and ChemCam have shown changes since we crossed over from the previous layered sulfate unit, but we can’t figure out the mineralogy from those data alone. As we’ve often seen before on Mars, the same chemical elements can crystallize into a number of different mineral assemblages. That’s even more the case in sedimentary rocks such as we are driving through, in which different grains in our rocks may have formed in different times and places. This also means that when we do get our mineral data, those minerals will tell us a lot about the history of these new-to-us rocks.
On board Curiosity, that mineral analysis is the job of the CheMin instrument, which uses X-ray diffraction to identify minerals. CheMin shines a narrow X-ray beam through a powdered sample in order to generate the diffraction pattern, which means that it needs a drilled sample. So the team today was busy looking for a drillable spot. Unfortunately the rover’s drill reach from today’s parking spot included only rocks that were too fractured or had too much debris sitting on them to be considered likely to produce a good drilled sample, so we will have to move, or “bump,” at least one more time before progressing to the drill preload test, which is the next step in drilling.
In the meantime, we are taking more measurements to understand the range of compositions that can be found in this rock layer. Dust removal (DRT) + APXS + LIBS + MAHLI were all planned for target “Holcomb Valley,” while a short distance away a second DRT/APXS/MAHLI measurement was planned for “Santa Ysabel Valley” and in another direction, a second LIBS for “Stough Saddle.” One long-distance ChemCam remote imaging mosaic was planned to cover a boxwork structure off in the distance. Mastcam had a relatively light day of imaging, with just a couple of small mosaics covering a nearby trough feature, and providing context for the RMI of the boxwork structure, in addition to documenting the two LIBS targets. The modern Mars environment was also recorded with a couple of movies to look for dust-devil activity, a measurement of atmospheric opacity, and a pair of suprahorizon observations to look for clouds, plus the usual passive observations by DAN and REMS to monitor the neutron environment, temperature, and humidity.
I’ll be on rover planning Wednesday as Geology and Mineralogy Science Theme Lead and looking forward to what we find — hopefully some drillable boxwork-unit bedrock!

A Dust Devil Photobombs Perseverance!
Perseverance self portrait, acquired by the WATSON camera on Sol 1500 on Mars. The Bell Island borehole where the rover acquired a sample is visible in the workspace in front of the rover. NASA/JPL-Caltech/MSSS Written by Athanasios Klidaras, Ph.D. candidate at Purdue University, and Megan Kennedy Wu, Senior Mission Operations Specialist at Malin Space Science Systems
To celebrate her 1,500th Martian day (“Sol”) exploring the red planet, the Perseverance rover used its robotic arm to take a selfie of the rover and the surrounding landscape. But when team members reviewed the photo, they were surprised to find that Perseverance had been photobombed!
As the rover sat at the “Pine Pond” workspace, located on the outer rim of Jezero crater, which it has been exploring for the past several months, the Wide Angle Topographic Sensor for Operations and eNgineering (WATSON) camera on the end of its arm was used to acquire a 59-image mosaic of the rover. This is the fifth “selfie” that Perseverance has acquired since landing on Mars in 2021. The rover’s robotic arm is not visible in the self portrait because — just like a selfie you would take with your own cellphone camera — rover operators make sure not to have the arm get “in the way” of the body of the rover. This is even easier to do on Mars because Perseverance needs to take 59 different images at slightly different arm positions to build up the selfie, and the elbow of the robotic arm is kept out of the way while the images are acquired. You can find more details about the Sol 1500 selfie here, and this YouTube video shows how the rover arm moves when these activities take place.
While snapping away, Perseverance was photobombed by a dust devil in the distance! These are relatively common phenomena both on Mars and in Earth’s desert regions, and form from rising and rotating columns of warm air, which gives the appearance of a dust tornado. Just like many other weather patterns, there is a peak “season” for dust-devil activity, and Jezero crater is in the peak of that season now (late northern spring). The one seen in the selfie is fairly large, about 100 meters, or 328 feet, across. While Perseverance regularly monitors the horizon for dust-devil activity with Navcam movies, this is the first time the WATSON camera on the end of the robotic arm has ever captured an image of a dust devil!
The dark hole in front of the rover, surrounded by gray rock powder created during the drilling process, shows the location of Perseverance’s 26th sample. Nicknamed “Bell Island” after an island near Newfoundland, Canada, this rock sample contains small spherules, thought to have formed by volcanic eruptions or impacts early in Martian history. Later, this ancient rock was uplifted during the impact that formed Jezero crater. Now that the rover has successfully acquired the spherule sample the science team was searching for, Perseverance is leaving the area to explore new rock exposures. Last week, the rover arrived at an exposure of light-toned bedrock called “Copper Cove,” and the science team was interested to determine if this unit underlies or overlies the rock sequence explored earlier. After performing an abrasion to get a closer look at the chemistry and textures, the rover drove south to scout out more sites along the outer edge of the Jezero crater rim.
