Preventing bone loss in space
Microgravity Associated Bone Loss-B (MABL-B) assesses the effects of microgravity on bone marrow stem cells and may provide a better understanding of the basic molecular mechanisms of bone loss that occurs during spaceflight and from normal aging on Earth.NASA A study of bone-forming stem cells in microgravity could provide insight into the basic mechanisms of the bone loss astronauts experience during long-duration space flight ahead of future exploration of the Moon and Mars.
Researchers identified a protein in the body called IL-6 that can send signals to stem cells to promote either bone formation or bone loss. This work evaluates whether blocking IL-6 signals could reduce bone loss during spaceflight. Results could improve our understanding of bone loss on Earth due to aging or disease and lead to new prevention and treatment strategies.
Printing parts, tools in space
Printing parts, tools in space
The objective of the Metal 3D printer aboard the International Space Station is to gain experience with operating and evaluating the manufacturing of spare parts in microgravity to support long duration space missions.NASA As mission duration and distance from Earth increase, resupply becomes harder. Additive manufacturing, or 3D printing, could be used to make parts and dedicated tools on demand, enhancing mission autonomy.
Research aboard the space station has made strides in 3D printing with plastic, but it is not suitable for all uses. Investigations from ESA’s (European Space Agency) Metal 3D Printer builds on recent successful printing of the first metal parts in space.
Bioprinting tissue in microgravity
Maturation of Vascularized Liver Tissue Construct in Zero Gravity (MVP Cell-07) is a biotechnology experiment studying bioprinted, or lab grown, liver tissues complete with blood vessels in space. The results could improve astronaut health on long missions and lead to new ways to treat patients on Earth.NASA Researchers plan to bioprint liver tissue containing blood vessels on the ground and examine how the tissue develops in microgravity. Results could help support the eventual production of entire functional organs for transplantation on Earth.
A previous mission tested whether this bioprinted liver tissue survived and functioned in space. This experimental round could show whether microgravity improves the development of the bioprinted tissue.
Biomanufacturing drug-delivery medical devices
The InSPA-Auxilium Bioprinter will test 3D printing medical implant devices designed to deliver drugs and treat various health conditions such as nerve inuries. Printing on the International Space Station may produce higher-quality devices than on Earth.NASA Scientists are creating an implantable device in microgravity that could support nerve regrowth after injuries. The device is created through bioprinting, a type of 3D printing that uses living cells or proteins as raw materials.
Traumatic injuries can create gaps between nerves, and existing treatments have a limited ability to restore nerve function and may result in impaired physical function. A bioprinted device to bridge nerve gaps could accelerate recovery and preserve function.
Cargo Highlights
NASA’s SpaceX 33rd commercial resupply mission will carry over 5,000 pounds of cargo to the International Space Station.NASA Hardware

Close-Up Views of NASA’s DART Impact to Inform Planetary Defense
Photos taken by the Italian LICIACube, short for the LICIA Cubesat for Imaging of Asteroids. These offer the closest, most detailed observations of NASA’s DART (Double Asteroid Redirection Test) impact aftermath to date. The photo on the left was taken roughly 2 minutes and 40 seconds after impact, as the satellite flew past the Didymos system. The photo on the right was taken 20 seconds later, as LICIACube was leaving the scene. The larger body, near the top of each image is Didymos. The smaller body in the lower half of each image is Dimorphos, enveloped by the cloud of rocky debris created by DART’s impact. NASA/ASI/University of Maryland On Sept. 11, 2022, engineers at a flight control center in Turin, Italy, sent a radio signal into deep space. Its destination was NASA’s DART (Double Asteroid Redirection Test) spacecraft flying toward an asteroid more than 5 million miles away.
The message prompted the spacecraft to execute a series of pre-programmed commands that caused a small, shoebox-sized satellite contributed by the Italian Space Agency (ASI), called LICIACube, to detach from DART.
Fifteen days later, when DART’s journey ended in an intentional head-on collision with near-Earth asteroid Dimorphos, LICIACube flew past the asteroid to snap a series of photos, providing researchers with the only on-site observations of the world’s first demonstration of an asteroid deflection.
After analyzing LICIACube’s images, NASA and ASI scientists report on Aug. 21 in the Planetary Science Journal that an estimated 35.3 million pounds (16 million kilograms) of dust and rocks spewed from the asteroid as a result of the crash, refining previous estimates that were based on data from ground and space-based observations.
While the debris shed from the asteroid amounted to less than 0.5% of its total mass, it was still 30,000 times greater than the mass of the spacecraft. The impact of the debris on Dimorphos’ trajectory was dramatic: shortly after the collision, the DART team determined that the flying rubble gave Dimorphos a shove several times stronger than the hit from the spacecraft itself.
“The plume of material released from the asteroid was like a short burst from a rocket engine,” said Ramin Lolachi, a research scientist who led the study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The important takeaway from the DART mission is that a small, lightweight spacecraft can dramatically alter the path of an asteroid of similar size and composition to Dimorphos, which is a “rubble-pile” asteroid — or a loose, porous collection of rocky material bound together weakly by gravity.
“We expect that a lot of near-Earth asteroids have a similar structure to Dimorphos,” said Dave Glenar, a planetary scientist at the University of Maryland, Baltimore County, who participated in the study. “So, this extra push from the debris plume is critical to consider when building future spacecraft to deflect asteroids from Earth.”
The tail of material that formed behind Dimorphos was prominent almost 12 days after the DART impact, giving the asteroid a comet-like appearance, as seen in this image captured by NASA’s Hubble Space Telescope in October 2022. Hubble’s observations were made from roughly 6.8 million miles away. NASA, ESA, STScI, Jian-Yang Li (PSI); Image Processing: Joseph DePasquale DART’s Star Witness
NASA chose Dimorphos, which poses no threat to Earth, as the mission target due to its relationship with another, larger asteroid named Didymos. Dimorphos orbits Didymos in a binary asteroid system, much like the Moon orbits Earth. Critically, the pair’s position relative to Earth allowed astronomers to measure the duration of the moonlet’s orbit before and after the collision.
Ground and space-based observations revealed that DART shortened Dimorphos’ orbit by 33 minutes. But these long-range observations, made from 6.8 million miles (10.9 million kilometers) away, were too distant to support a detailed study of the impact debris. That was LICIACube’s job.
After DART’s impact, LICIACube had just 60 seconds to make its most critical observations. Barreling past the asteroid at 15,000 miles (21,140 kilometers) per hour, the spacecraft took a snapshot of the debris roughly once every three seconds. Its closest image was taken just 53 miles (85.3 km) from Dimorphos’ surface.
The short distance between LICIACube and Dimorphos provided a unique advantage, allowing the cubesat to capture detailed images of the dusty debris from multiple angles.
The research team studied a series of 18 LICIAcube images. The first images in the sequence showed LICIACube’s head-on approach. From this angle, the plume was brightly illuminated by direct sunlight. As the spacecraft glided past the asteroid, its camera pivoted to keep the plume in view.
This animated series of images was taken by a camera aboard LICIACube 2 to 3 minutes after DART crashed into Dimorphos. As LICIACube made its way past the binary pair of asteroids Didymos, the larger one on top, and Dimorphos, the object at the bottom. The satellite’s viewing angle changed rapidly during its flyby of Dimorphos, allowing scientists o get a comprehensive view of the impact plume from a series of angles. ASI/University of Maryland/Tony Farnham/Nathan Marder As LICIACube looked back at the asteroid, sunlight filtered through the dense cloud of debris, and the plume’s brightness faded. This suggested the plume was made of mostly large particles — about a millimeter or more across — which reflect less light than tiny dust grains.
Since the innermost parts of the plume were so thick with debris that they were completely opaque, the scientists used models to estimate the number of particles that were hidden from view. Data from other rubble-pile asteroids, including pieces of Bennu delivered to Earth in 2023 by NASA’s OSIRIS-REx spacecraft, and laboratory experiments helped refine the estimate.
“We estimated that this hidden material accounted for almost 45% of the plume’s total mass,” said Timothy Stubbs, a planetary scientist at NASA Goddard who was involved with the study.
While DART showed that a high-speed collision with a spacecraft can change an asteroid’s trajectory, Stubbs and his colleagues note that different asteroid types, such as those made of stronger, more tightly packed material, might respond differently to a DART-like impact. “Every time we interact with an asteroid, we find something that surprises us, so there’s a lot more work to do,” said Stubbs. “But DART is a big step forward for planetary defense.”
The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, managed the DART mission and operated the spacecraft for NASA’s Planetary Defense Coordination Office as a project of the agency’s Planetary Missions Program Office.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This National Aviation Day graphic shows Orville Wright surrounded by the faces of some of NASA’s aeronautical innovators.NASA / Maria Werries The first “A” in NASA stands for Aeronautics – so naturally that means today, Aug. 19, National Aviation Day, is one of our favorite days all year!
National Aviation Day was first proclaimed in 1939 by President Franklin Roosevelt to celebrate the birthday of aviation pioneer Orville Wright, who, with his brother Wilbur, in 1903, were the first humans to achieve powered flight.
Each year since the President first marked the occasion, sky-faring Americans have come together on this date in an annual celebration of flight – a time to revel in spreading our wings and slipping the surly bonds of Earth.
All of us at NASA share in that celebration. We love everything about flight, whether it’s into space or within Earth’s atmosphere.
Our aeronautical innovators are dedicated to improving the design of airplanes to carry on pioneering new technologies in high-speed flight, airframes and propulsion methods, aerospace engineering modelling, and automating airspace and safety management.
Our heritage in aviation research goes back more than 100 years. We’ve helped air travel become a safe, efficient, reliable form of transportation. If you’re heading to an airport, keep an eye out for these NASA-developed aviation technologies you might see on your flight:
WINGLETSNASA studies led to development of vertical extensions that can be attached to wing tips in order to reduce aerodynamic drag without having to increase wingspan. Winglets help increase an airplane’s range, decrease fuel use, and today can be seen on airplanes everywhere.NASA CHEVRON NOZZLESWorking with its industry partners, NASA researchers determined an effective way to reduce noise levels on the ground and in the passenger cabin was to add saw tooth-shaped cut outs, or chevrons, to structures such as exhaust nozzles and cowlings of jet engines.NASA / The Boeing Company GLASS COCKPITS NASA created and tested the concept of replacing dial and gauge instruments with flat panel digital displays. The displays present information more efficiently and provide the flight crew with a more easily understood picture of the aircraft’s health and position.NASA Langley / Sean Smith How Will You Celebrate?
How else can you celebrate National Aviation Day? Here are seven ideas:
Visit your local science museum or NASA visitor center
Explore your local science center for exhibits about aviation and how an airplane flies. And if you live within a short drive from Norfolk, Virginia; Cleveland, or San Francisco, you might consider checking out the visitor centers associated with NASA’s Langley Research Center, Glenn Research Center, or Ames Research Center, respectively. These major NASA field centers play host to the majority of NASA’s aeronautics research. (NASA’s Armstrong Flight Research Center, the fourth of NASA’s aeronautics centers, is located within the restricted area of Edwards Air Force Base in California so they do not have a public visitor’s center.)
Watch an aviation-themed movie
There’s no shortage of classic aviation-themed movies available to watch in any format (streaming, DVD, cinema, library rentals, etc.), and with any snacks (popcorn, nachos, gummies, etc.). We dare not attempt a comprehensive list, but a good place to start is our documentary “X-59: NASA’s “Quesst” for Quiet Supersonic Flight” available to stream on NASA+.
Build an airplane
Why not? It doesn’t have to be big enough to actually fly in – plastic model kits of the world’s most historic aircraft can be just as rewarding and just as educational, especially for kids who might be thinking about a career as an engineer or technician. In fact, many astronauts will tell you their love of aviation and space began with putting models together as a child. Another idea: Grab some LEGO bricks and build the airplane of your dreams. Or make it easy on yourself, fold a paper airplane and shoot it across the room.
Take an introductory flight lesson
Pilots will tell you there is a wonderful sense of freedom in flying, not to mention the incredible views and the personal sense of accomplishment. At the same time, being a pilot is not for everyone, but you won’t know unless you try! Many general aviation airports in the nation have a flight school that may offer an introductory flight lesson at a discounted price. And if you want a taste of flight without leaving the ground, computer desktop flight simulators such as Microsoft Flight Simulator or X-Plane are popular choices and can get you into the virtual sky in short order.
Visit your local library or download a NASA e-book
Aviation-themed books, whether fact or fiction, are all over the shelves of your local library – literally. That’s because there’s no single Dewey Decimal number for aviation. A book about aviation history will be in a different section of the library than a book about how to design an airplane. And creative nonfiction books such as the Mark Vanhoenacker’s “Skyfaring,” or autobiographies such as Eileen Collins’ “Through the Glass Ceiling to the Stars,” are off on yet another shelf. Don’t hesitate to ask your librarian for help. And when you get back from the library, or while still there, jump online and check out the NASA e-books you can download and own for free.
Have a plane spotting picnic near an airport
At Washington’s National Airport, it’s Gravelly Point. In Tampa, Florida it’s International Mall. If you live near a major international airport, chances are you know the best place where the locals can go to watch aircraft take off and land up close. Be sure to take heed of any security restrictions about where you can and can’t go. But once you have your spot picked out, then load up your picnic basket and camp out for an evening of plane spotting. See how many different types of airplanes you can count or identify.
Follow what we’re doing to transform aviation
NASA’s aeronautical innovators are working to transform air transportation to meet the future needs of the global aviation community. Sounds like a big job, right? It is and there are many ways in which NASA is doing this. Improving an airplane’s aerodynamics, making airplanes more efficient and quieter, working with the Federal Aviation Administration to improve air traffic control – the list could go on for many thousands of more words. Bookmark our NASA Aeronautics topic page and follow us on social media @NASAaero.
So remember this National Aviation Day, NASA is with you when you fly!

GRX-810 is a new metal alloy developed by NASA for 3D printing parts that can withstand the extreme temperatures of rocket engines, allowing affordable printing of high-heat parts.NASA Until now, additive manufacturing, commonly known as 3D printing, of engine components was limited by the lack of affordable metal alloys that could withstand the extreme temperatures of spaceflight. Expensive metal alloys were the only option for 3D printing engine parts until NASA’s Glenn Research Center in Cleveland, Ohio, developed the GRX-810 alloy.
The primary metals in the GRX-810 alloy include nickel, cobalt, and chromium. A ceramic oxide coating on the powdered metal particles increases its heat resistance and improves performance. Known as oxide dispersion strengthened (ODS) alloys, these powders were challenging to manufacture at a reasonable cost when the project started.
However, the advanced dispersion coating technique developed at Glenn employs resonant acoustic mixing. Rapid vibration is applied to a container filled with the metal powder and nano-oxide particles. The vibration evenly coats each metal particle with the oxide, making them inseparable. Even if a manufactured part is ground down to powder and reused, the next component will have the qualities of ODS.
The benefits over common alloys are significant – GRX-10 could last up to a year at 2,000°F under stress loads that would crack any other affordable alloy within hours. Additionally, 3D printing parts using GRX-810 enables more complex shapes compared to metal parts manufactured with traditional methods.
Elementum 3D, an Erie, Colorado-based company, produces GRX-810 for customers in quantities ranging from small batches to over a ton. The company has a co-exclusive license for the NASA-patented alloy and manufacturing process and continues to work with the agency under a Space Act Agreement to improve the material.
“A material under stress or a heavy load at high temperature can start to deform and stretch almost like taffy,” said Jeremy Iten, chief technical officer with Elementum 3D. “Initial tests done on the large-scale production of our GRX-810 alloy showed a lifespan that’s twice as long as the small-batch material initially produced, and those were already fantastic.”
Commercial space and other industries, including aviation, are testing GRX-810 for additional applications. For example, one Elementum 3D customer, Vectoflow, is testing a GRX-810 flow sensor. Flow sensors monitor the speed of gases flowing through a turbine, helping engineers optimize engine performance. However, these sensors can burn out in minutes due to extreme temperatures. Using GRX-810 flow sensors could improve airplane fuel efficiency, reduce emissions and hardware replacements.
Working hand-in-hand with industry, NASA is driving technology developments that are mutually beneficial to the agency and America’s space economy. Learn more: https://spinoff.nasa.gov/
