Extracting Oxygen from Moon Soil using Concentrated Sunlight | NASA Science

Extracting Oxygen from Moon Soil using Concentrated Sunlight | NASA Science

NASA’s Carbothermal Reduction Demonstration (CaRD) project completed an important step toward using local resources to support human exploration on the Moon. The CaRD team performed integrated prototype testing that used concentrated solar energy to extract oxygen from simulated lunar soil, while confirming the production of carbon monoxide through a solar-driven chemical reaction. Lunar soil, or regolith, is a fine, unconsolidated layer of rock fragments, mineral grains, and dust covering the Moon, formed primarily by meteoroid impacts and space weathering.

If deployed on the Moon, this technology could enable the production of propellant using only lunar materials and sunlight, significantly reducing the cost and complexity of sustaining a long-term human presence on the lunar surface. The same downstream systems used to convert carbon monoxide into oxygen can also be adapted to convert carbon dioxide into oxygen and methane on Mars.  

The integrated prototype brought together a carbothermal oxygen production reactor developed by Sierra Space, a solar concentrator designed by NASA’s Glenn Research Center in Cleveland, precision mirrors produced by Composite Mirror Applications, and avionics, software, and gas analysis systems from NASA’s Kennedy Space Center in Florida. NASA’s Johnson Space Center in Houston led project management, systems engineering, testing, and development of key hardware and ground support systems.

The CaRD project was funded by NASA’s Game Changing Development program under the Space Technology Mission Directorate.

It aims to produce oxygen from simulated lunar regolith for use at the Moon’s south pole. During this integrated test, the team combined the concentrator, mirrors, and control software and confirmed the production of carbon monoxide.

Shenzhou-21 Crew Performs Space Experiments, Maintenance | China Space Station

Shenzhou-21 Crew Performs Space Experiments, Maintenance | China Space Station


China's Shenzhou-21 astronauts have steadily carried out a series of tasks aboard the Tiangong Space Station over the past week, including in-orbit experiments, equipment maintenance, and health monitoring, the China Manned Space Agency (CMSA) stated on March 15, 2026.

The crew, comprised of mission commander Zhang Lu and astronauts Wu Fei and Zhang Hongzhang, have spent more than four months in orbit and remain in good health, according to the CMSA.

Inside the station's core module, cherry tomatoes cultivated using a water aeroponic device are thriving. The astronauts documented the plants with photos, harvested ripe fruit, and sealed plants and produce separately for preservation.

Building on the success of the cherry tomato cultivation, the team will conduct aeroponic experiments with wheat, carrots, plus medicinal and other edible plants as planned. These trials aim to validate key technologies and expand the range of crops and technical capabilities for space cultivation.

In the field of space materials science, the crew completed several tasks, including cleaning the experimental chamber in the unpressurized compartment, replacing experimental samples, maintaining the electrodes of the central mechanism, and cleaning the window cover of the central mechanism.

They also completed related microgravity combustion science experiments. This included replacing the burner and sampling cover inside the experiment cabinet, as well as vacuumization and exhaust gas discharge.

Additional work included maintenance of the regenerative life support system equipment, microorganism monitoring and assessment, and medical training. This helps familiarize the astronauts with rescue operation methods and force application characteristics in a microgravity environment.

The Shenzhou-21 crewed spacecraft blasted off from the Jiuquan Satellite Launch Center in northwest China on October 31, 2025, sending the three astronauts to the orbiting space station on a six-month mission.

China Long March-8A Rocket Launches New Internet Satellites from Hainan

China Long March-8A Rocket Launches New Internet Satellites from Hainan

China launched a Long March-8A carrier rocket on Friday, March 13, 2026, in the southern island province of Hainan, sending a new group of Internet satellites into space. The rocket lifted off at 03:48 from the Hainan commercial spacecraft launch site. It successfully placed the payloads, the 20th group of low-orbit Internet satellites, into preset orbit.

The Long March-8A carrier rocket, designed by the China Academy of Launch Vehicle Technology (CALT), represents a significant upgrade to the Long March-8 series. It successfully conducted its maiden flight on Feb. 11, 2025.

The rocket, 50.5 meters long with a takeoff weight of 371 tonnes, is capable of carrying up to seven tonnes to a sun-synchronous orbit at an altitude of 700 km. It is designed specifically for high-density, rapid constellation deployment, serving as a core vehicle for China's satellite Internet constellation construction.

So far, it has successfully completed eight missions. About 15 launch missions have been scheduled for the Long March 8 series rockets this year, involving the Long March 8A and Long March 8 rockets.

As a new-generation medium-lift liquid-fueled carrier rocket, the Long March 8 series rockets have become the mainstay for China's low-to-medium orbit satellite launches since its maiden flight, thanks to its modular design, high cost-effectiveness, and rapid response capabilities.

Hainan International Commercial Aerospace Launch Co., Ltd., or HICAL, is a Chinese state-owned company that operates the Wenchang Commercial Space Launch Site, China's first commercial spaceport. Established in 2022, HICAL is the first commercially incorporated company in China to independently own and manage a spaceport.

Dwarf Galaxy NGC 5264 in Hydra: An Irregular Island | Hubble Space Telescope

Dwarf Galaxy NGC 5264 in Hydra: An Irregular Island | Hubble Space Telescope

This image, courtesy of the NASA/European Space Agency Hubble Space Telescope’s Advanced Camera for Surveys (ACS), captures the glow of distant stars within NGC 5264, a dwarf galaxy located just over 15 million light-years away in the constellation of Hydra (The Sea Serpent).

Dwarf galaxies like NGC 5264 typically possess around a billion stars—just one per cent of the number of stars found within the Milky Way. They are usually found orbiting other, larger, galaxies such as our own, and are thought to form from the material left over from the messy formation of their larger cosmic relatives.

NGC 5264 clearly possesses an irregular shape—unlike the more common spiral or elliptical galaxies—with knots of blue star formation. Astronomers believe that this is due to the gravitational interactions between NGC 5264 and other galaxies nearby. These past flirtations sparked the formation of new generations of stars that now glow in bright shades of blue.

Aurora over New Zealand

Aurora over New Zealand

Sam Lawler: "Auroras were just barely visible to the naked eye, the colours only showed up with a camera."

Also known as the southern lights (aurora australis) or northern lights (aurora borealis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

Zodiacal Light over Arizona | Earth Science

Zodiacal Light over Arizona | Earth Science

Astrophotographer David Blanchard: "The zodiacal light was easy to see over northern Arizona on Thursday night. This was taken just before the end of astronomical twilight."

What's that strangely diffused white light? 
Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset—or just before sunrise—and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and that it slowly spirals into the Sun.

Arizona is a landlocked state in the Southwestern region of the United States, sharing the Four Corners region of the western United States with Colorado, New Mexico, and Utah. It also borders Nevada to the northwest and California to the west, and shares an international border with the Mexican states of Sonora and Baja California to the south and southwest.

The Necklace Nebula of Sagitta: "In the Sky with Diamonds" | Hubble

The Necklace Nebula of Sagitta: "In the Sky with Diamonds" | Hubble


The interaction of two doomed stars has created this spectacular ring adorned with bright clumps of gas—a diamond necklace of cosmic proportions. Fittingly known as The Necklace Nebula, this planetary nebula is located 15,000 light-years away from Earth in the small, dim constellation of Sagitta (The Arrow).

The Necklace Nebula also goes by the less glamorous name of PN G054.2-03.4. It was produced by a pair of tightly orbiting Sun-like stars. Roughly 25,000 years ago, one of the aging stars expanded and engulfed its smaller companion, creating something astronomers call a “common envelope”. The smaller star continued to orbit inside its larger companion, increasing the bloated giant’s rotation rate until large parts of it spun outwards into space. This escaping ring of debris formed the Necklace Nebula with particularly dense clumps of gas forming the bright “diamonds” around the ring.

The pair of stars that created the Necklace Nebula remain so close together—separated by only a few million kilometers—that they appear as a single bright dot in the center of this image. Despite their close encounter the stars are still furiously whirling around each other, completing an orbit in just over a day.

Globular Cluster NGC 6496 in Scorpius: A Heavy-metal Home | Hubble

Globular Cluster NGC 6496 in Scorpius: A Heavy-metal Home | Hubble


This 10.5-billion-year-old globular cluster, NGC 6496, is home to heavy-metal stars of a celestial kind! The stars comprising this spectacular spherical cluster are enriched with much higher proportions of metals—elements heavier than hydrogen and helium, are in astronomy curiously known as metals—than stars found in similar clusters.

A handful of these high-metallicity stars are also variable stars, meaning that their brightness fluctuates over time. NGC 6496 hosts a selection of long-period variables—giant pulsating stars whose brightness can take up to, and even over, a thousand days to change—and short-period eclipsing binaries, which dim when eclipsed by a stellar companion.

The nature of the variability of these stars can reveal important information about their mass, radius, luminosity, temperature, composition, and evolution, providing astronomers with measurements that would be difficult or even impossible to obtain through other methods.

NGC 6496 was discovered in 1826 by Scottish astronomer James Dunlop. The cluster resides at about 35,000 light-years away in the southern constellation of Scorpius (The Scorpion).

NASA Artemis II Crew Moon Mission Menu | Johnson Space Center

NASA Artemis II Crew Moon Mission Menu | Johnson Space Center

Artemis II Launch Update: NASA completed the agency’s Artemis II Flight Readiness Review on Thursday, March 12, 2026, and polled “go” to proceed toward launch. NASA is targeting Thursday, March 19, to roll the Space Launch System (SLS) rocket and Orion spacecraft to launch pad 39B in advance of a launch attempt Wednesday, April 1, pending close out of remaining open work.

Artemis II: What’s on the Menu?
The food flying aboard Artemis II is designed to support crew health and performance during the mission around the Moon. With no resupply, refrigeration, or late-load capability, all meals must be carefully selected to remain safe, shelf-stable, and easy to prepare and consume in NASA’s Orion spacecraft. Food selections are developed in coordination with space food experts and the crew to balance calorie needs, hydration, and nutrient intake while accommodating individual crew preferences.

Here are a frequently asked questions about how NASA designs and prepares food systems for Artemis II to support crew health:

What considerations go into selecting and packaging food for safe use during a mission like Artemis II?
Food selection for Artemis II considers shelf life, food safety, nutritional value, crew preference, and compatibility with Orion’s mass, volume, and power requirements. Foods must be easy to prepare and consume in microgravity, minimize crumbs, and remain safe and stable throughout the mission. The crew provided input well before the meals were packed for the test flight.

How are menu items structured to make up an astronaut’s typical daily meals?
On a typical mission day—excluding launch and reentry—astronauts have scheduled time for breakfast, lunch, and dinner. Each astronaut is allotted two flavored beverages per day, which may include coffee. Beverage options are limited due to upmass constraints, which restrict how much food and drink can be carried onboard.

Fresh foods will not be flying on Artemis II as Orion does not have refrigeration nor the late load capability required for fresh foods. Shelf-stable foods help manage food safety and quality throughout the intended shelf life in a compact, self-contained spacecraft, while also reducing the risk of crumbs or particulates in microgravity.

How do Artemis II menus vary from those used during Apollo, space shuttle, and International Space Station missions?
Artemis II menus reflect decades of advancement in space food systems. Apollo missions relied on early food technologies with limited variety, while space shuttle missions expanded menu options and onboard preparation. The International Space Station benefits from regular resupply and occasional fresh foods. In contrast, Artemis II uses a fixed, pre-selected menu designed for a self-contained space vehicle with no resupply.

How much input does the Artemis II crew have in choosing their meals?
The Artemis II crew has direct input into menu selection. Crew members sample, evaluate, and rate all foods on the standard menu during preflight testing, and their preferences are balanced with nutritional requirements and what Orion can accommodate. Final, crew-specific menus are set well before launch. Two to three days’ worth of food for each crewmember is packed together in a single container, providing flexibility for meal selection during the mission.

How are menus tailored for each mission phase, such as launch, transit, and re-entry?
Menus are tailored based on the spacecraft’s food preparation capabilities during each hase of flight. Certain foods, such as freeze-dried meals, require hydration using Orion’s potable water dispenser. This capability is not available during some phases, including launch and landing. As a result, foods selected for those phases must be ready-to-eat and compatible with the spacecraft’s operational constraints, while a broader range of food options are available once full food preparation systems are up and running.

How is space food prepared in the Orion spacecraft?
Food aboard Orion is ready-to-eat, rehydratable, thermostabilized, or irradiated. The crew uses Orion’s potable water dispenser to rehydrate foods and beverages and a compact, briefcase-style food warmer to heat meals as needed.

What challenges come with designing and preparing food for a contained spacecraft like Orion?
Designing food systems for Orion requires balancing nutrition, safety, and crew preference within strict mass, volume, and power limits inside a compact, shared cabin.

Foods must be easy to store, prepare, and consume in microgravity while minimizing crumbs and waste. Preparation is intentionally simple, using ready-to-eat, rehydratable, thermostabilized, or irradiated foods that can be safely prepared without interfering with crew operations or spacecraft systems.

The Artemis II test flight will take Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA and Mission Specialist Jeremy Hansen from the Canadian Space Agency (CSA), around the Moon and back to Earth 

Artemis II will pave the way for new U.S. crewed missions on the lunar surface in preparation to send the first astronauts to Mars.

Northrop Grumman's Cygnus XL cargo spacecraft, with its two prominent cymbal-shaped UltraFlex solar arrays, departs the International Space Station moments after being released from the grasp of the Canadarm2 robotic arm completing its resupply mission. 

The Canadarm2 robotic arm's latching end effector, or LEE, is pictured from a window on the International Space Station after it had released Northrop Grumman's Cygnus XL cargo spacecraft into Earth orbit ending its resupply mission. The orbital outpost was soaring 271 miles above the Atlantic Ocean off the coast of southern Argentina when this photograph was taken. 

Expedition 74 Flight Engineer and NASA Astronaut Jessica Meir: "Another day on the International Space Station brings the departure of another vehicle, the last of our three cargo vehicles on the US Operating Segment (USOS). Today, we bid farewell to the Northrop Grumman Cygnus NG-23 cargo vehicle, named after our late colleague NASA astronaut Willie McCool. 

As I watched Cygnus disappear over the horizon, I took a moment to reflect and honor Willie, and all of the STS-107 crew, who honorably gave their lives in their effort to advance science and space exploration. 

Godspeed S.S. William 'Willie' C. McCool, thank you for your service!"

At 7:06 a.m. EDT, March 12, 2026, Northrop Grumman’s Cygnus XL was released from the Canadarm2 robotic arm that earlier detached the cargo spacecraft from the Earth-facing port of the International Space Station’s Unity module. At the time of release, the station was flying about 260 miles over the south Atlantic Ocean.

The Cygnus XL spacecraft successfully departed the space station more than seven months after arriving at the orbiting laboratory to deliver about 11,000 pounds of supplies, scientific investigations, commercial products, hardware and other cargo for NASA and its international partners.

The spacecraft will be commanded to deorbit on Saturday, March 14, to dispose of several thousand pounds of trash during its re-entry into Earth’s atmosphere, where it will "harmlessly" burn up.

CG 4 in Puppis: The Globule and The Galaxy

CG 4 in Puppis: The Globule and The Galaxy

Is this a cosmic monster ready to devour an unsuspecting galaxy?

Thankfully, that is not the case. The red “monster” shown in the featured image is cometary globule CG 4, 1,300 light-years away in the constellation Puppis. CG 4 is a molecular cloud, where hydrogen becomes cold enough to form molecules that can be brought together by gravity to create stars. The shape of CG 4 resembles that of a comet, but its head is 1.5 light-year in diameter and its tail is 8 light-years long; for comparison, the distance from the Earth to the sun is only 8 light-minutes.

Astronomers think that the tail of a cometary globule could have been shaped by a nearby supernova explosion or by irradiation from hot, massive stars. Indeed, CG 4 and other nearby globules point away from the Vela Supernova Remnant, at the center of the Gum Nebula. The edge-on spiral galaxy, ESO 257-19, is more than a hundred million light-years beyond CG 4, and is completely safe from the “monster”.

Inside the World's Largest Telescope: "It's Progressing Fast!" | ESO

With its 39 m primary mirror, the European Southern Observatory's Extremely Large Telescope (ELT) will be the biggest and most powerful optical telescope in the world. In this episode of Chasing Starlight, we take you on an exclusive tour of the ELT, from the massive telescope structure inside the dome to the facility that will coat the mirrors with reflective silver.

The Extremely Large Telescope (ELT) is a massive building. It is almost as tall as London's Big Ben clock tower and larger than Rome's Colosseum. The construction materials used for the ELT include: 10,000 tonnes of steel, 30 million bolts or 500 km of cables.

The ELT stands at Cerro Armazones in Chile's Atacama Desert. 
Altitude: 3,046 meters
Planned year of technical first light: 2027
