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…

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…

Los Angeles Fires Seen from International Space Station

NeRD

NASA/Don Pettit On Jan. 10, 2025, NASA astronaut Don Pettit posted two images of the Los Angeles fires from the International Space Station. Multiple destructive fires broke out in the hills of Los Angeles County in early January 2025, fueled by a dry landscape and winds that gusted up to 100 miles per hour. See satellite imagery of the fires. Image credit: NASA/Don Pettit

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…

JAXA’s First Wooden Satellite Deploys from Space Station

NeRD

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…
