NASA’s IMAP will use 10 science instruments to study and map the heliosphere, a vast magnetic bubble surrounding the Sun protecting our solar system from radiation incoming from interstellar space. This mission and its two rideshares will orbit the Sun near Lagrange point 1, about one million miles from Earth, where it will scan the heliosphere, analyze the composition of charged particles, and investigate how those particles move through the solar system. This will provide information on how the Sun accelerates charged particles, filling in essential puzzle pieces to understand the space weather environment across the solar system. The IMAP spacecraft also will continuously monitor solar wind and cosmic radiation. Scientists can use this information to evaluate new and improved capabilities for space weather prediction tools and models, which are vital for the health of human space explorers and the longevity of technological systems, like satellites and power grids, that can affect life on Earth.
The agency’s Carruthers Geocorona Observatory is a small satellite set to study the exosphere, the outermost part of Earth’s atmosphere. Using ultraviolet cameras, it will monitor how space weather from the Sun impacts the exosphere, which plays a crucial role in protecting Earth from space weather events that can affect satellites, communications, and power lines. The exosphere, a cloud of neutral hydrogen extending to the Moon and possibly beyond, is created by the breakdown of water and methane by ultraviolet light from the Sun, and its glow, known as the geocorona, has been observed globally only four times before this mission.
The SWFO-L1 mission, managed by NOAA and developed with NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and commercial partners, will use a suite of instruments to provide real-time measurements of solar wind, along with a compact coronagraph to detect coronal mass ejections from the Sun. The observatory, serving as an early warning beacon for potentially destructive space weather events, will enable faster and more accurate forecasts. Its 24/7 data will support NOAA’s Space Weather Prediction Center in protecting vital infrastructure, economic interests, and national security, both on Earth and in space.
David McComas, professor, Princeton University, leads the IMAP mission with an international team of 25 partner institutions. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built the spacecraft and operates the mission. NASA’s IMAP is the fifth mission in NASA’s Solar Terrestrial Probes program portfolio. The Explorers and Heliophysics Project Division at NASA Goddard manages the program for the agency’s Heliophysics Division of NASA’s Science Mission Directorate.
NASA’s Launch Services Program, based at NASA Kennedy, manages the launch service for the mission.

The 33rd SpaceX commercial resupply services mission for NASA, scheduled to liftoff from the agency’s Kennedy Space Center in Florida in late August, is heading to the International Space Station with an important investigation for the future of bone health.
The experiment will test how microgravity affects bone-forming and bone-degrading cells and explore potential ways to prevent bone loss. This research could help protect astronauts on future long-duration missions to the Moon and Mars, while also advancing treatments for millions of people on Earth who suffer from osteoporosis.
Mesenchymal stem cells (MSCs) are derived from human bone marrow and stained with rapid red dye NASA Space’s Hidden Health Mystery
During long-duration missions, astronauts may experience a gradual reduction in bone density—typically around 1% to 2% per month—even with consistent exercise routines. While scientists understand how bones work on Earth, they aren’t sure exactly why bones weaken so quickly in microgravity.
Previous research aboard the space station revealed that microgravity changes how stem cells behave and what substances they release. Scientists now want to dig deeper into these cellular changes to better understand what causes bone loss in space and explore potential ways to prevent it.
Blocking a Potential Bone Thief
The Microgravity Associated Bone Loss-B (MABL-B) investigation focuses on special stem cells called mesenchymal stem cells, or MSCs. As these cells mature, they build new bone tissue in the body.
Scientists suspect that a protein called IL-6 might be the culprit behind bone problems in space. Data from the earlier MABL-A mission suggests that microgravity promotes the type of IL-6 signaling that enhances bone degradation. The MABL-B experiment will investigate this by testing ways to block this IL-6 signaling pathway.
The experiment will grow mesenchymal stem cells alongside other bone cells in special containers designed for space research. Cells will be cultured for 19 days aboard the space station, with crew members periodically collecting samples for analysis back on Earth.
How this benefits space exploration
The research could lead to targeted treatments that protect astronauts from bone loss during long-duration missions to the Moon, Mars, and beyond. As crews venture farther from Earth, bone health becomes increasingly critical since medical evacuation or emergency return to Earth won’t be possible during Mars missions.
How this benefits humanity
The findings could provide new insights into age-related bone loss that affects millions of people on Earth. Understanding how the IL-6 protein affects bone health may lead to new treatments for osteoporosis and other bone conditions that come with aging.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
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/

On January 7, 2021, NASA astronaut Kate Rubins serviced samples for Bacterial Adhesion and Corrosion. This investigation looked at how spaceflight affects the formation of microbial biofilms and tested a silver-based disinfectant.NASA This November marks a quarter century of continuous human presence aboard the International Space Station, which has served as a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including human missions to the Moon and Mars. To kick off the orbiting laboratory’s silver 25th anniversary countdown, here are a few silver-themed science investigations that have advanced research and space exploration.
Antimicrobial properties
Silver has been used for centuries to fight infection, and researchers use its unique properties to mitigate microbial growth aboard the space station. Over time, microbes form biofilms, sticky communities that can grow on surfaces and cause infection. In space, biofilms can become resistant to traditional cleaning products and could infect water treatment systems, damage equipment, and pose a health risk to astronauts. The Bacterial Adhesion and Corrosion investigation studied the bacterial genes that contribute to the formation of biofilms and tested whether a silver-based disinfectant could limit their growth.
Another experiment focused on the production of silver nanoparticles aboard the space station. Silver nanoparticles have a bigger surface-to-volume ratio, allowing silver ions to come in contact with more microbes, making it a more effective antimicrobial tool to help protect crew from potential infection on future space missions. It also evaluated whether silver nanoparticles produced in space are more stable and uniform in size and shape, characteristics that could further enhance their effectiveness.
Wearable tech
Silver is a high-conductivity precious metal that is very malleable, making it a viable option for smart garments. NASA astronauts aboard the orbiting laboratory tested a wearable monitoring vest with silver-coated sensors to record heart rates, cardiac mechanics, and breathing patterns while they slept. This smart garment is lightweight and more comfortable, so it does not disturb sleep quality. The data collected provided valuable insight into improving astronauts’ sleep in space.
Silver crystals
In microgravity, there is no up or down, and weightlessness does not allow particles to settle, which impacts physical and chemical processes. Researchers use this unique microgravity environment to grow larger and more uniform crystals unaffected by the force of Earth’s gravity or the physical processes that would separate mixtures by density. The NanoRacks-COSMOS investigation used the environment aboard the station to grow and assess the 3D structure of silver nitrate crystals. The molecular structure of these superior silver nitrate crystals has applications in nanotechnology, such as creating silver nanowires for nanoscale electronics.
