The Republic of San Marino became the 76th signatory to the Artemis Accords during a ceremony in the town of Rimini on Friday with NASA and U.S. Department of State officials present.
“San Marino joins a growing coalition of like-minded nations committed to the peaceful, transparent, and responsible exploration of space,” said NASA Deputy Administrator Matt Anderson. “President Trump has directed NASA to build a Moon Base and establish an enduring presence on the lunar surface. As we do, we are putting the principles of the Accords into practice. NASA has invited every Artemis Accords signatory to participate in our return to the Moon through scientific payloads, technology demonstrations, CubeSats, and other capabilities. San Marino is already looking toward that future.”
Minister of Industry and Technological Research Rossano Fabbri signed on behalf of San Marino. Gregory Mann, NASA Europe representative, participated in the ceremony with the U.S. Consul General in Florence Joseph Tordella.
“We are pleased and honored that the Republic of San Marino has been welcomed as the 76th signatory state of the Artemis Accords,” said Fabbri. “We fully share the principles and values expressed in the Artemis Accords, and we are convinced that the signatory states united under the Accords will make a tangible contribution to promoting international cooperation in space and ensuring the use of space for peaceful purposes.”
In 2020, NASA and the State Department joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. They introduced the first set of practical principles aimed at enhancing the safety and coordination between nations as they explore the Moon, Mars, and beyond, committing nations to:
Explore peaceably and transparently
Render aid to those in need
Enable access to scientific data
Ensure activities do not interfere with those of others
Preserve historically significant sites and artifacts by developing best practices
By signing the Artemis Accords, nations open the door to opportunities for future lunar exploration with NASA, advancing humanity’s return to the Moon, and shaping the Golden Age of exploration and innovation.
Spacecraft propulsion traditionally relies on volatile fuels and separate, bulky systems for different types of maneuvering in space. NASA is working to change that paradigm. Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently completed a rigorous series of environmental and physical tests on a new small satellite designed to make spaceflight safer and more efficient.
The ASCENT (Advanced Spacecraft Energetic Non-Toxic) Propulsion Dual Mode mission is a flight demonstration of a spacecraft about the size of a large shoebox. The mission will test a single, integrated propulsion system that uses a common fuel tank to feed two different types of engines.
Dr. Nehemiah Williams, the demonstration’s project manager at NASA, prepares to start testing the mission’s flight hardware in a clean room at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The mission will demonstrate a single, non-toxic propulsion system that combines both high-thrust and low-thrust capabilities into a common tank.

Typically, spacecraft carry two separate propulsion systems to navigate: a high-thrust chemical system for rapid movements like entering orbit, and a low-thrust electric system for highly efficient, slow maneuvers like maintaining a position. This requires multiple fuel tanks and heavy plumbing, which eats up valuable space and weight.
The spacecraft being developed uses a single non-toxic propellant called ASCENT. By feeding both a high-thrust combustion engine and low-thrust electrospray thrusters from one central tank, the spacecraft saves critical mass and volume. For future missions, this means more room for scientific instruments and the ability to launch on smaller, less expensive rockets.
Bringing this concept to flight requires a nationwide collaborative effort. While NASA Marshall manages the mission, the spacecraft relies on electrospray thrusters developed by the Massachusetts Institute of Technology, a chemical propulsion module built by Plasma Processes, and a spacecraft bus integrated by the Georgia Institute of Technology.
“There are a lot of odds and ends, and a lot of small challenges and some big ones,” said Nehemiah Williams, the demonstration’s project manager at NASA Marshall. “But ensuring the functionality of the propulsion system across all these different teams is what makes the mission successful.”
Before a spacecraft can safely operate in the harsh environment of low Earth orbit, it must pass a battery of tests on the ground. Over the past few months, the engineering team at Marshall has put the flight hardware through its paces inside the center’s Small Spacecraft Servicing and Integration Lab.
To verify the integrity of the unified propulsion system, the team conducted extensive leak testing. Engineers performed a pressurized helium leak test of the spacecraft inside a vacuum chamber to ensure the integrity of the spacecraft’s seals, successfully proving those seals were working as intended. Because the system shares a single tank of ASCENT propellant to feed two different thruster types, ensuring that the fuel lines and valves are perfectly sealed is vital for mission safety and success.

The 6-U CubeSat recently underwent rigorous spin, thermal vacuum, and leak tests to ensure its innovative, non-toxic propulsion system is ready for the extreme environment of space.

The team also subjected the spacecraft to thermal vacuum testing. Space is an unforgiving environment characterized by a total lack of air and extreme temperature swings. By placing the spacecraft inside a specialized vacuum chamber that mimics these harsh conditions, engineers can ensure that the electronics, thrusters, and mechanical systems will operate normally once in orbit.
Additionally, the spacecraft underwent a spin test. Just like a tire on a car, a spacecraft needs to be perfectly balanced. The spin test measures the spacecraft’s mass properties and center of gravity. This validates the CubeSat’s ability to stably fly and maintain the correct attitude, allowing its antennas to communicate with Earth and its solar panels to accurately catch the Sun’s rays.
With the environmental and physical testing now complete, the mission is entering its final stages of preparation. The team will complete the final system checkouts, integrate the spacecraft’s solar arrays, and ship the hardware to its launch destination.
The ASCENT Propulsion Dual Mode mission is manifested to launch no earlier than October 1 as a payload aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.
Once deployed into an orbit about 325 miles above Earth, the spacecraft will begin a nine-month mission. After an initial checkout period, the operations team will execute short chemical and electric maneuvers. If successful, the spacecraft will spend several months performing multiple orbit-raising and lowering maneuvers, alternating between its high-thrust and low-thrust engines to prove the dual-mode concept works in space.
The ASCENT Propulsion Dual Mode mission is managed and funded by NASA’s Small Spacecraft & Distributed Systems (SSDS) within the agency’s Research and Technology Mission Directorate at NASA Headquarters in Washington. SSDS is based at NASA’s Ames Research Center in California’s Silicon Valley.
After rapidly intensifying, Hurricane Polo spins off Mexico’s Pacific coast on September 23, 2026 (left), over unusually warm waters (right). NASA Earth Observatory images by Michala Garrison, using data from the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Aqua satellite and the MUR SST (Multiscale Ultrahigh Resolution Sea Surface Temperature) project.
In mid-September 2026, Hurricane Polo began as a tropical disturbance off the Pacific coast of Mexico. By September 20, it was organized enough to qualify as a tropical depression, and by the next day it was a tropical storm.
From there, Polo launched into a period of rapid intensification that left meteorologists searching for adjectives strong enough to convey what was happening. Some described the storm’s rate of intensification and strength as “jaw-dropping,” others as “astonishing,”and others as “absolute insanity.”
“Polo went through a period of what can only be described as explosively rapid intensification,” said Gary Partyka, an atmospheric scientist with the Global Modeling and Assimilation Office (GMAO) at NASA’s Goddard Space Flight Center, in an email. “This was RAPID, rapid intensification.”
The storm was in an environment that was “near perfect” for strengthening, Partyka said, characterized by weak wind shear, high moisture, warmer ocean temperatures, and high levels of atmospheric instability.
Several observers leaned on extreme rapid intensification—a technical classification meaning the storm’s wind speeds increased at least 60 knots (111 kilometers or 69 miles per hour) within a 24-hour period. By September 22, the storm’s maximum sustained wind speed had risen by 90 knots (167 kilometers per hour or 104 miles per hour) within 24 hours, hitting category 5 strength. In its normally staid forecast discussions, the National Hurricane Center called the intensification “truly remarkable.”
When NOAA’s Hurricane Hunter aircraft flew over the storm on September 22, researchers estimated winds of nearly 285 kilometers (180 miles) per hour. That would make it the third-strongest storm on record in the eastern Pacific by maximum sustained winds and the fastest on record to go from a tropical depression to a category 5 storm, according to some analysts.
On the afternoon of September 23, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image (left), Polo was churning off the coast of Guerrero, southwest of Acapulco. With maximum sustained winds of 230 kilometers (145 miles) per hour, the storm was category 4 strength when the image was acquired, having undergone an eyewall replacement cycle that weakened it slightly.
“The satellite imagery of Polo is very impressive, with the storm’s large, clear eye and extensive outflow pattern,” said Kristen Corbosiero, an atmospheric scientist at the State University of New York at Albany, who is working on a NASA project that uses satellite data to study tropical cyclone ventilation. “Weak winds above the system and good outflow at the top of the system also contributed to Polo’s rapid intensification.”
As Polo developed, it moved over areas where sea surface temperatures were as high as 32 degrees Celsius (90 degrees Fahrenheit)—2 to 3 degrees warmer than usual for September 23. Surface waters across much of the region were above 27.8°C (82°F), the temperature generally required to sustain and intensify hurricanes.
The map above (right) is based on data from the Multiscale Ultrahigh Resolution Sea Surface Temperature (MUR SST) project at NASA’s Jet Propulsion Laboratory, which blends satellite measurements from NASA, NOAA, and international missions with observations from ships and buoys. Rather than absolute temperatures, the map shows anomalies—how much warmer or cooler the ocean surface was on September 23, 2026, than the project’s 2003-2014 average for that date.
While the map above conveys temperatures at the water surface, the presence of warm water deeper in the column has likely contributed to the storm’s staying power, Corbosiero added. Sometimes hurricanes churn up cooler water from deep in the column that can slow a storm’s intensification, but in this case the cool water wake behind the storm appears minimal, and measurements and models show high ocean heat content at considerable depths.
Both Partyka and Corbosiero cautioned against attributing Polo’s rapid intensification directly to El Niño’s unusually warm surface temperatures in the central and eastern Pacific Ocean. Several hurricanes in this region have undergone rapid intensification in the past during La Niñaand neutral conditions, Corbosiero noted, including Hurricane Otis in 2023 and Patricia in 2015, both category 5 storms.
However, the overall amount of tropical cyclone activity in the eastern Pacific does typically increase during El Niño due to changes in large-scale ocean and atmospheric circulation patterns, and that’s what has happened so far in 2026. As of September 24, the accumulated cyclone energy in the region was nearly twice the norm, according to data from Colorado State University.

Four crew members from three space agencies will launch to the International Space Station no earlier than spring 2027 for a long-duration science expedition as part of NASA’s SpaceX Crew-14 mission.
NASA astronauts Kayla Barron and Chris Birch will serve as spacecraft commander and pilot, with JAXA (Japan Aerospace Exploration Agency) astronaut Makoto Suwa, and Roscosmos cosmonaut Arutyun Kiviryan as mission specialists. After docking, Crew-14 will join the space station’s Expedition 75/76.
This mission is the 14th commercial crew rotation with SpaceX under NASA’s Low Earth Orbit Program. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future exploration missions to the Moon and Mars and to benefit people on Earth.
This will be Barron’s second flight to the space station. She was selected as a NASA astronaut in 2017. Barron earned a bachelor’s degree in systems engineering from the U.S. Naval Academy in Annapolis, Maryland and a master’s degree in nuclear engineering from the University of Cambridge in England. A commander in the U.S. Navy, Barron earned her submarine warfare officer qualification, deploying three times aboard the USS Maine. She first launched to the space station in 2021 aboard NASA’s SpaceX Crew-3 mission, spending a total of 177 days in space across space station Expeditions 66/67. She completed two spacewalks and served as lead robotics operator for another. Most recently, Barron supported the development of new technologies and operational concepts for NASA’s Artemis program.
Selected as a NASA astronaut in 2021, Birch graduated from the University of Arizona in Tucson with degrees in mathematics and biochemistry and molecular biophysics. She earned a doctorate in biological engineering from the Massachusetts Institute of Technology, and later taught bioengineering at the University of California, Riverside, and scientific writing and communication at the California Institute of Technology in Pasadena. Birch competed as a decorated track cyclist on the U.S. National Team and was named to the Olympic Long Team for the 2020 Tokyo Games. She has served as a capsule communicator, supporting crews aboard the space station and during the Artemis II mission. Birch was crew lead for Expedition 72, working with flight control teams to help manage daily operations, and served as a crew representative for NASA’s Orion Program, supporting Artemis II mission development and operations. This will be her first spaceflight.
The Crew-14 mission also is the first spaceflight assignment for Suwa. Before JAXA selected him as an astronaut candidate in 2023, Suwa spent nearly a decade with the World Bank Group. Previously, he served in Rwanda as a Japan Overseas Cooperation Volunteer before joining the United Nations World Meteorological Organization. Suwa holds a doctorate in geosciences from Princeton University and completed basic training to become certified as an astronaut in 2024.
This mission will be Kiviryan’s first trip to the space station. He graduated from Saint Petersburg Suvorov Military School in 2010 and later studied at the Baltic State Technical University. He graduated in 2015 as an engineer specializing in rocket science and completed training in the operation of computer-controlled machines. Kiviryan was selected for the Gagarin Research and Test Cosmonaut Training Center Cosmonaut Corps in 2021 and has served as a test cosmonaut since 2023.
For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that aren’t possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

NASA announced the winners of the Deep Space Food Challenge: Mars to Table Thursday, with the top $300,000 prize being awarded to Chinyere Ukeje of Philadelphia, Pa. for the Adaptive Nourishment Infrastructure (ANI) food system concept. This competition challenged solvers to explore innovative solutions for integrated space food systems that would provide safe, nutritious meals to astronauts living and working in space.
Mars to Table launched in January 2026 as a follow on to the Deep Space Food Challenge, which NASA ran from 2021-2014 in collaboration with CSA (Canadian Space Agency). The original challenge focused on prototyped novel food production methods, while the 2026 competition asked teams to conceptualize space meals not as individual technology components, but as a complete food-production system that would offer a variety of food with limited crew time and work needed to maintain the food system. After judging 113 submissions by teams hailing from 33 countries and 28 U.S. states, the agency selected five winning teams for the 2026 challenge, awarding a combined $650,000.
“We’re thrilled to keep advancing the future of space food systems with this challenge,” said Jennifer Edmunson, program manager for Centennial Challenges at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The future of human space exploration will rely on innovative food systems, and it is amazing how much ingenuity this challenge has helped us identify from participants near and far.”
Currently, astronaut meals are almost entirely cooked, packaged, and sent to the International Space Station from the Space Food Systems Laboratory at NASA’s Johnson Space Center. A one-way trip to Mars will take at least nine months, so bringing all required meals will not be sustainable for such missions. From shelf stability issues to mass restrictions, pre-packaged foods cannot be the default option for future Martian astronauts.
In search of viable solutions for future space food operations, teams were tasked with ideating and designing systems in response to a mission scenario that addressed a 15-person astronaut crew for 500 Martian sols, or about 513 Earth days. The challenge focused on surface operations and system integration, and each team delivered a design layout, meal plan, concept of operations, and walkthrough video.
“The criteria we laid out for this competition were challenging, but intentionally so,” said Mars to Table head judge Dr. Alexander Meyers, who supports NASA Centennial Challenges through Noetic Strategies from the agency’s Kennedy Space Center in Florida. “This challenge spotlights the complexity of a complete space food system and the human ingenuity required to solve these problems. Every new idea presented in this challenge represents a possible new tool in NASA’s plans for the future of space exploration.
NASA named five winners of the Mars to Table Challenge. These technologies provide NASA with inspirational launching pads for future deep space food systems.
The first-place winner, Chinyere Ukeje, developed the concept of ANI, a modular food ecosystem combining controlled-environment agriculture, fermentation and fungi cultivation, and closed-loop nutrient recycling through bioreactors with limited Earth-provisioned foods to produce 50% of the food away from Earth. ANI, named after the Nigerian Earth goddess of harvest and fertility, envisions a system that cooks fresh meals daily and has provisions to work through shortages of power, water, equipment, or crew time.
The second-place prize of $200,000 was awarded to Cislune of Rosemead, Calif. for the Fresh, Ferment, Reserve food infrastructure. The proposed system grows model-selected crops, converts part of the harvest into familiar foods in instrumented culture cassettes, and uses a protected Earth-loaded reserve to supplement in cases of biological variability, utility curtailment, and rejected batches.
Additional prizes include:
Applied Frameworks Award ($50,000): Ohā Kanu from Hilo, Hawaii with ʻOhā Kanu: An Ahupuaʻa-Inspired Food System for Mars
Mission Simulation Award ($50,000): Orbital Health Systems, Inc. from Evansville, Ind. with New Lunar Settlers Cookbook (Mars Edition)
Human-Centered Design Award ($50,000): Autonomic Resilience Collective from Bentonville, Ark. with Adaptive Endurance and Growth through Integrated Sustenance (AEGIS) Mars
NASA also recognized one international team:
International Winner: Astrofood from Ellezelles, Belgium with Food Resilience Ecosystem for Space Habitats (FRESH)
The Deep Space Food Challenge: Mars to Table is managed at NASA Marshall by Centennial Challenges, part of the Prizes, Challenges, and Crowdsourcing Program within NASA’s Research and Technology Mission Directorate. The challenge is also supported by NASA’s Division of Biological and Physical Sciences, Heliophysics Division, Planetary Science Program, Human Research Program, and Earth Science Division.
Centennial Challenges have a legacy of more than 20 years engaging the public to solve complex problems that benefit NASA’s broader initiatives. Past challenges have spurred advances in robotics, additive manufacturing, power and energy, textiles, chemistry, and biology.
The Deep Space Food Challenge: Mars to Table is also supported by subject matter experts at NASA Johnson and NASA Kennedy. The Methuselah Foundation and Floor23 Digital support the administration of this challenge.
NASA announced Wednesday a mission to explore the history and evolution of the universe, PRIMA (PRobe far-Infrared Mission for Astrophysics), is advancing to the next phase of development. This space telescope is the first in a new class of NASA astrophysics missions, called Probe Explorers, within the agency’s longstanding Explorers Program.
“The PRIMA mission is humanity’s next window into the deep universe. It will unveil the obscure across cosmic time to better understand the formation of planets, stars, black holes, and even how water on Earth came to be,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington.
NASA selected PRIMA to move into Phase B, the stage of development that advances the preliminary design and technology development for the mission. The mission is subject to a confirmation review, based on technical, programmatic, and cost performance, to determine its readiness to begin implementation in Phase C. If confirmed, PRIMA’s project cost is capped at $1.2 billion, not including launch and other non-project costs. The observatory will be targeted to launch in 2033, for a planned five-year mission.
With a 5.9-foot telescope, PRIMA will conduct deep, sensitive surveys of the universe in far-infrared light, helping bridge the gap between existing infrared observatories, such as NASA’s James Webb Space Telescope, and radio telescopes. By studying radiant energy that only emerges in the far-infrared, PRIMA will address a wide range of questions about the universe. This includes the origins of planets outside our solar system, how galaxies and their black holes have grown and evolved over cosmic history, and how dust and heavy elements have built up in the universe over time – all helping paint a better picture of why the universe looks the way it does today.
“A single mission alone can’t probe all the universe’s mysteries. But by extending the survey capabilities of our fleet into far-infrared wavelengths with PRIMA, we’re enabling an incredibly comprehensive look at the cosmos,” said Shawn Domagal-Goldman, director, Astrophysics Division, NASA Headquarters. “With our Webb and Roman space telescopes, we set a cadence of launching premiere-class missions in both halves of the decade. We’re going to keep that up and kick off the next decade with PRIMA, as part of a pipeline that will consistently have missions of this caliber ready to go.”
The National Academies of Sciences, Engineering, and Medicine’s 2020 Decadal Survey, Pathways to Discovery in Astronomy and Astrophysics for the 2020s, recommended NASA establish this new Probe Explorers mission class. NASA selected PRIMA for development after detailed evaluation of concept studies for Probe Explorer missions, based on their scientific merit in alignment with the Decadal Survey’s recommendations, feasibility of their development plans on cost and schedule, and use of technologies that could support the development of future large missions.
NASA’s Jet Propulsion Laboratory in Southern California will manage the PRIMA mission. Other partners include NASA’s Goddard Space Flight Center in Greenbelt, Maryland and NASA’s Marshall Space Flight Center in Huntsville, Alabama. The PRIMA mission also will have contributions from international partners: CNES (Centre National D’Etudes Spatiales), ASI (Agenzia Spaziale Italiana), DLR (Deutsches Zentrum für Luft- und Raumfahrt), CSA (Canadian Space Agency), KASI (Korea Astronomy and Space Science Institute), JAXA (Japan Aerospace Exploration Agency), and the UK Space Agency.
The Explorers Program is the oldest continuous NASA program designed to provide frequent, low-cost access to space using principal investigator-led space science investigations relevant to the Science Mission Directorate’s astrophysics and heliophysics programs. Since the Explorer 1 launch in 1958, which discovered Earth’s radiation belts, the Explorers Program has launched more than 100 missions, including the Uhuru and Cosmic Background Explorer missions that led to Nobel prizes for their investigators.
The Explorers Program is managed by NASA Goddard for the Science Mission Directorate, which conducts a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system, and the universe.

Agricultural emissions represent an important and understudied part of Earth’s land and atmosphere systems. The FarmFlux mission will deploy more than a dozen sensors to measure ozone, methane, ammonia, particulates, and other pollutants rising from agricultural lands and animal farms and the interaction with the Earth’s atmosphere. The mission is jointly led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Colorado State University; and Boston University.
The Colorado deployment is the first series of flights for the FarmFlux mission. Additional low-altitude research flights are scheduled over farmland in Amarillo, Texas, from late October to early November. For the March to July 2027 growing season, research flights with a NASA P-3 Orion aircraft are scheduled in the Midwest and California’s Central Valley with a focus on croplands.

NASA’s Hubble Space Telescope captured this image of massive galaxy cluster MACS J0417 (left of center) on Sept. 19, 2026. This galaxy cluster acts as a gravitational lens, bending and magnifying light from objects far behind it. Supernova Athena, discovered by NASA’s James Webb Space Telescope in 2025, is predicted to reappear between now and early March 2027. Measuring the timing of Athena’s reappearances can help researchers map the mass of MACS J0417, which acts as a magnifying, foreground lens for distant objects, and refine our understanding of the expansion rate of the universe.
Hubble also completed its 200,000th orbit around Earth on Sept. 19, marking another new milestone for an observatory that continues to transform our understanding of the universe.

Arid shrublands in Western Australia were bursting with life in late austral winter 2026, when a profusion of wildflowers brought vivid colors to the rusty ochre landscape. After several wetter-than-normal months earlier in the year, dormant seeds in the soil awoke to produce carpets of blooms. Local experts think the display could be the best the area has seen in nearly two decades.
The images above, captured with the OLI (Operational Land Imager) on the NASA-USGS Landsat 8 satellite, compare the more verdant landscape of late August 2026 (right) with a similar time in 2025 (left), when it was drier. This area is located about 600 kilometers (370 miles) north of Perth in the Murchison region, one of Western Australia’s main areas for grazing sheep and cattle. The local vegetation includes grasses, saltbush, and the slow-growing evergreen mulga tree.
White flowers carpet the Western Australian outback.
Every so often, a variety of wildflowers makes an appearance, too. In 2026, rainfall totals were above average in June and very much above average in August due to several cold fronts moving through the area, according to Australia’s Bureau of Meteorology. The rains helped rouse a diverse mix of flowers to bloom across the outback, including on a radio astronomy site managed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia’s national science agency. The flower show included some threatened species, which the observatory has helped monitor on its formerly pastoral land.
Though the spectacle underfoot might have momentarily stolen the show, Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory, is primarily focused on what’s overhead and the exploration of deep space. At the Murchison site, CSIRO operates several antenna arrays that observe and catalog objects in the southern sky. The remote facility is situated within a “radio quiet” zone, where terrestrial communications and electronic devices are controlled to limit electromagnetic interference with the instruments.
Mulla mulla flowers appear in front of CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope.
Other telescopes in CSIRO’s purview in Australia have played crucial roles in NASA missions from the agency’s early years to today. The Murriyang radio telescope in Parkes, New South Wales, tracked Mariner 2—the first successful planetary science mission—in 1962 and was an important receiving station for the Apollo 11 mission to the Moon in 1969. CSIRO also manages and operates the Canberra Deep Space Communication Complex, one of three facilities in NASA’s global Deep Space Network that supports interplanetary spacecraft missions and collects radar and radio astronomy observations. Both supported the Artemis II mission in April 2026.
