Astronauts Set to Swab the Exterior of Station for Microbial Life

NeRD

NASA astronaut Victor Glover tests collection methods for ISS External Microorganisms in the Neutral Buoyancy Lab at Johnson Space Center. NASA Astronauts are scheduled to venture outside the International Space Station to collect microbiological samples during crew spacewalks for the ISS External Microorganisms experiment. This investigation focuses on sampling at sites near life support system vents to examine whether the spacecraft releases microorganisms, how many, and how far they may travel. This experiment could help researchers understand whether and how these microorganisms survive and reproduce in the harsh space environment…

Insights into metal alloy solidification Researchers report details of phase and structure in the solidification of metal alloys on the International Space Station, including formation of microstructures. Because these microstructures determine a material’s mechanical properties, this work could support improvements in techniques for producing coatings and additive manufacturing or 3D printing processes. METCOMP, an ESA (European Space Agency) investigation, studied solidification in microgravity using transparent organic mixtures as stand-ins for metal alloys. Conducting the research in microgravity removed the influence of convection and other effects of gravity. Results help scientists…

Peak Performance in Microgravity

NeRD

Science in Space January 2025 At the start of a new year, many people think about making positive changes in their lives, such as improving physical fitness or learning a particular skill. Astronauts on the International Space Station work all year to maintain a high level of performance while adapting to changes in their physical fitness, cognitive ability, sensory perception, and other functions during spaceflight. Research on the space station looks at how these qualities change in space, the ways those changes affect daily performance, and countermeasures to keep astronauts…

Measurements from space support wildfire risk predictions Researchers demonstrated that data from the International Space Station’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument played a significant role in the ability of machine learning algorithms to predict wildfire susceptibility. This result could help support development of effective strategies for predicting, preventing, monitoring, and managing wildfires. As the frequency and severity of wildfires increases worldwide, experts need reliable models of fire susceptibility to protect public safety and support natural resource planning and risk management. ECOSTRESS measures evapotranspiration, water use…

Astronaut Set to Patch NASA’s X-ray Telescope Aboard Space Station

NeRD

4 min read Astronaut Set to Patch NASA’s X-ray Telescope Aboard Space Station NASA astronaut Nick Hague will install patches to the agency’s NICER (Neutron star Interior Composition Explorer) X-ray telescope on the International Space Station as part of a spacewalk scheduled for Jan. 16. Hague, along with astronaut Suni Williams, will also complete other tasks during the outing. NICER will be the first NASA observatory repaired on-orbit since the last servicing mission for the Hubble Space Telescope in 2009. Hague and other astronauts, including Don Pettit, who is also currently on the…

NASA’s 2024 International Space Station Achievements

NeRD

City lights streak across Earth and an aurora is visible on the horizon as the International Space Station passes over Lake Michigan. NASA For more than 24 years, NASA has supported a continuous U.S. human presence aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth for the benefit of humanity. The space station is a springboard to NASA’s next great leaps in exploration, including future missions to the Moon under Artemis, and ultimately, human exploration of Mars.

Internal view of LignoSat’s structure shows the relationship among wooden panels, aluminum frames, and stainless-steel shafts. Credit: Kyoto University In December 2024, five CubeSats deployed into Earth’s orbit from the International Space Station. Among them was LignoSat, a wooden satellite from JAXA (Japanese Aerospace Exploration Agency) that investigates the use of wood in space. Findings could offer a more sustainable alternative to conventional satellites. A previous experiment aboard station exposed three species of wood to the space environment to help researchers determine the best option for LignoSat. The final design…

A method for evaluating thermophysical properties of metal alloys Simulation of the solidification of metal alloys, a key step in certain industrial processes, requires reliable data on their thermophysical properties such as surface tension and viscosity. Researchers propose comparing predictive models with experimental outcomes as a method to assess these data. Scientists use data on surface tension and viscosity of titanium-based alloys in industrial processes such as casting and crystal growth. Non-Equilibrium Solidification, Modelling for Microstructure Engineering of Industrial Alloys, an ESA (European Space Agency) investigation, examined the microstructure and…

4 Min Read Space Gardens NASA astronaut Kayla Barron with chile peppers in the station’s Advanced Plant Habitat. Credits: NASA Science in Space December 2024 As NASA plans missions to the Moon and Mars, one challenge is figuring out how to provide crew members with enough healthy food. Bringing along a supply for months or even years in space is impractical, and stored food can lose taste and nutritional value. Growing plants in space is one way to help solve this problem. Tending space gardens also has positive psychological effects…
