The first mission devoted to observing the Martian atmosphere and its evolution, NASA’s MAVEN (Mars Atmosphere and Volatile Evolution), has ended after more than 11 years in orbit at Mars and a decade beyond its primary, one-year mission. The spacecraft was heard last on Dec. 6, when it experienced an unexpected loss of signal after it passed behind the Red Planet.
NASA will host a media teleconference at 2 p.m. EDT today, Wednesday, June 3, to discuss MAVEN’s achievements.
The agency convened an anomaly review board in February to evaluate recovery efforts and assess the spacecraft’s probable current state. The review board has determined that the MAVEN spacecraft is not recoverable, and it is no longer capable of performing its science and data relay mission, which is consistent with the mission team’s findings.
Telemetry from MAVEN prior to the spacecraft’s passage behind Mars in December showed all subsystems working normally. After the spacecraft emerged, NASA’s Deep Space Network (DSN) did not observe a signal. A brief fragment of telemetry data from analysis of radio signals recorded by the DSN’s open-loop receivers indicated the spacecraft was in safe mode and rotating at an unusually high rate when it emerged from behind Mars, indicating a disruption in MAVEN’s orbit trajectory. The review board concluded that due to this rotation, the batteries on the spacecraft had drained, causing the communications system to lose power and rendering MAVEN in an unrecoverable state.
These preliminary findings do not address a potential root cause for the anomaly, which still is being investigated. The review board is expected to provide its final report later this year. NASA has begun the official process of decommissioning the MAVEN mission, following standard procedures to archive the full mission dataset for the science and exploration communities.
“The science MAVEN has given us is key to informing what kind of radiation protection and safety measures we must take before sending humans to Mars,” said Louise Prockter, director of the Planetary Science Division at NASA Headquarters in Washington. “The data collected from MAVEN will continue to provide valuable insight into Mars for decades to come.”
Launched in November 2013, the MAVEN mission explored the Red Planet’s upper atmosphere, ionosphere, and interactions with the Sun to explore the loss of the Martian atmosphere to space. Understanding atmospheric loss gives scientists insight into the history of the planet’s atmosphere and climate, liquid water, and planetary habitability.
“The MAVEN mission has truly advanced our understanding of the Martian atmosphere and evolution. This dataset has had a tremendous impact on the field,” said Shannon Curry, MAVEN’s principal investigator and a researcher at the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder. “Our science team is exceptionally proud of all of these amazing discoveries.”
Sun’s impact on Mars
One of MAVEN’s first major results was that the erosion of Mars’ atmosphere increases significantly during solar storms. The team studied how the solar wind, which is a stream of charged particles continually streaming from the Sun, and solar storms continually strip away Mars’ atmosphere, as well as how this process played a key role in altering the Martian climate from a potentially habitable world to today’s cold, arid planet. The MAVEN mission made unprecedented strides in advancing our understanding of how the Sun and space weather affect Mars, as it was the only spacecraft that could simultaneously take measurements of both the Sun and the Martian atmospheric response.
Martian light shows
The MAVEN mission discovered several types of auroras that light up when energetic particles plunge into the atmosphere, bombarding gases and making them glow. The MAVEN team showed that protons create new kinds of auroras at Mars. On Earth, proton auroras only occur in very small regions near the poles, whereas at Mars they can occur everywhere.
Mars’ atmosphere sputters into space
To better understand how Mars lost most of its atmosphere, MAVEN measured atmospheric sputtering for the first time at any planet. The team did this by observing argon, which is a noble gas, meaning it rarely reacts with other constituents in the Martian atmosphere. The only significant way it can be removed is by atmospheric sputtering, a process where ions crash into the Martian atmosphere at high enough speeds that they splash gas molecules out of the atmosphere, much like doing a cannonball into a pool. The team used 11 years of data to reveal the presence of sputtered argon at high altitudes in the exact locations that the energetic particles crashed into the atmosphere, showing sputtering in real time.
Understanding Mars’ dusty secrets
In 2018, a series of dust storms created a dust cloud so large that it enveloped the Red Planet. The MAVEN team studied how this “global” dust storm affected Mars’ upper atmosphere to understand how these events affected the escape of water to space. It confirmed that heating from dust storms can loft water molecules far higher into the atmosphere than usual, leading to a sudden surge in water lost to space.
Chasing comets
In addition to Martian science, MAVEN contributed to NASA’s effort to observe comet 3I/ATLAS at Mars. Over the course of 10 days last year, the MAVEN team designed a new observing campaign to capture 3I/ATLAS by taking multiple images of the comet in several wavelengths, much like using various filters on a camera. Then it snapped high-resolution UV images to identify the hydrogen coming from the comet. By studying a combination of these images, scientists can identify a variety of molecules and better understand the comet’s composition and history.
During the mission’s lifetime, MAVEN’s science team produced more than 800 publications, and additional publications are planned.
In addition to science, the MAVEN spacecraft was an instrumental player in NASA’s Mars Relay Network, communicating data from Mars rovers to Earth. It also holds the solar system record for most data relayed from another planet in a single day.

From late May into early June 2026, a broad, slow-spinning storm churned north-northwest over the Philippine Sea toward southern Japan. Typhoon Jangmi’s rainbands unleashed torrential rainfall across a vast swath of the region, triggering flooding concerns in several areas.
The VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite captured this nighttime image (above) of the storm at about 16:40 Universal Time on May 30 (1:40 a.m. Japan Standard Time on May 31). Around that time, the typhoon produced sustained winds of 120 kilometers (75 miles) per hour, based on 1-minute averages reported by the Joint Typhoon Warning Center (JTWC). That’s equivalent to a category 1 storm on the Saffir-Simpson hurricane wind scale.
The image shows a detailed view of the eyewall and eye, with a diameter that is on the larger end of the spectrum, according to Scott Braun, a research meteorologist at NASA’s Goddard Space Flight Center. There also appears to be some low-level rotation on the eastern side of the eye, producing features known as “mesocyclones” that are partially obscured by high-level clouds. Though they appear striking, the features are fairly typical, Braun noted.
The second image shows a wider view of the same storm one day later. The VIIRS on the NOAA-20 satellite acquired this image at about 16:40 Universal Time on May 31 (1:40 a.m. Japan Standard Time on June 1), when the storm was a slightly stronger typhoon with sustained winds of 130 kilometers (80 miles) per hour.
In both images, Jangmi’s eye was still located south of Okinawa. However, the storm’s outer cloud bands already reached over land as the storm moved north. Forecasts called for the storm to make a close approach to Okinawa and then turn northeast toward the Amami region around June 1-2. It was expected to continue delivering large amounts of rain, especially along the nation’s Pacific coast, according to news reports.

A mobile wastewater treatment system built at NASA’s Kennedy Space Center in Florida that can help prepare for long-duration missions on the Moon and Mars departed the spaceport and arrived at the University of North Dakota in Grand Forks. Graduate students at the university will test the technology under conditions designed to closely mimic the challenges of operating on another planetary surface.
The Divergent Deployable Wastewater Treatment Facility is designed to turn crew wastewater into useful resources, which future explorers will need every day. At the University of North Dakota, teams will integrate this new wastewater system with the university’s Integrated Lunar/Martian Analog Habitat. Student operators and NASA researchers will study how the facility performs when connected to a habitat-like environment and exposed to the kinds of operational limits crews could face on another planet.
“NASA’s Artemis program is laying the groundwork for a sustained human presence on the Moon, where habitats will need to operate far from the steady resupply chain that supports astronauts in partial gravity,” said Luke Roberson, surface water systems lead within the Mars Campaign Office at NASA Kennedy. “To solve that challenge, we are developing the future of sustainable lunar surface systems to process wastewater into nutrient feedstocks for plants and biomanufacturing.”
Housed inside an 8.5-by-24-foot trailer, the facility brings together three biological reactor systems, a vertical garden, water-polishing hardware, environmental monitoring, autonomous control software, and safety systems. The trailer was outfitted at NASA Kennedy to function as a deployable laboratory and to travel between at least two simulation test sites as the technology matures.
Unlike wastewater systems on Earth, this facility keeps waste streams separate. That divergent approach is important for small crews, because wastewater from four to eight people can be highly concentrated. Urine, hygiene water, laundry water, fecal waste, and food waste each contain different levels of salts, solids, carbon, nitrogen, phosphorus, and other compounds. Treating them separately allows each stream to be processed by the reactor best suited for the job.
To do that, the system uses three different bioreactors to treat waste streams. The Anaerobic Phototrophic Membrane Bioreactor processes fecal and food waste and converts it into a nutrient-rich wastewater that can support plant growth. The Suspended Aerobic Membrane Bioreactor processes urine and flush water. The Membrane Aerated Biological Reactor treats graywater from hygiene and laundry activities. Collectively, the bioreactors process nutrients to feed the facility’s vertical garden and prepare the water for reuse. Inside that garden, crops will grow hydroponically, or without using soil, by using nutrient solutions derived from the bioreactors. Researchers will compare crop performance with plants grown using standard hydroponic nutrients.
At North Dakota, under a NASA EPSCoR (Established Program to Stimulate Competitive Research) grant, the facility was connected to the Integrated Lunar/Martian Analog Habitat through a bathroom interface that includes a urine-diverting toilet. The setup will allow different waste streams to be separated at the source and sent to the correct treatment systems. In parallel, Ali Alshami’s team is developing novel membrane-based separation technologies intended for future integration into the divergent wastewater facility to improve water recovery efficiency, contaminant rejection, and overall system resilience for long-duration habitation missions.
“The tests will help NASA evaluate real-world operation, crew training needs, system reliability, and how wastewater simulants compare with actual human metabolic waste in an analog mission environment,” said Alshami.
These efforts are focused on advancing compact, energy-efficient treatment approaches capable of handling complex wastewater streams generated in closed-loop extraterrestrial environments.
“The testing campaign at the University of North Dakota supports the facility’s technology maturation from laboratory-scale validation toward demonstration in a relevant Inflatable Lunar/Martian Analog Habitat environment,” said Pablo De Leon, professor and department chair of Space Studies at the University of North Dakota.
Lessons learned could inform future higher-fidelity tests, including potential integration with NASA’s next generation of yearlong simulated Mars missions via isolation analogs at the agency’s Johnson Space Center in Houston.
The work is part of NASA’s broader Bioregenerative Life Support Systems effort, which is developing biological approaches to reduce dependence on Earth-supplied consumables. In future lunar or Martian habitats, systems like the wastewater treatment facility could help close life support loops by recovering water, recycling nutrients, supporting crop production, and reducing the amount of waste that must be stored or discarded. Further NASA research completed trade studies demonstrating how bioregenerative life support becomes more effective for space travel over current life support technologies.
NASA researchers also are exploring how wastewater-recovered resources could support in-space manufacturing. One effort is studying how nutrient-rich water from bioregenerative wastewater systems could feed microbes that produce lactic acid, which can be turned into polylactic acid. The material could one day serve as a binder for 3D printing with lunar or Martian regolith, the loose, fragmental surface material, or could be used for replacement parts, extending the value of recovered waste beyond water and food systems.
“By sending the facility from NASA Kennedy to North Dakota, the agency is moving a key part of that circular economy out of the lab and into a real-world test,” said J.J. Edelmann, surface systems domain lead for the Mars Campaign Office at NASA Headquarters in Washington. “The work may begin with wastewater, but its goal is much larger. We want to help future crews live sustainably on the Moon, learn how to operate farther from Earth, and carry those lessons forward to Mars.”
