    CSA (Canadian Space Agency) astronaut Joshua Kutryk and NASA astronaut Anil Menon began a spacewalk at 8:36 a.m. EST outside the International Space Station airlock to install and deploy the eighth and final IROSA on the 3B channel of the space station, completing the power augmentation upgrades,

  • Astronauts are Go for Final Power Upgrade Spacewalk

    From left, astronauts Joshua Kutryk of CSA (Canadian Space Agency) and Anil Menon of NASA pose for pre-flight crew portraits at Johnson Space Center in Houston, Texas.

    Mission managers have given the go for two astronauts to exit the International Space Station on Thursday and install its eighth and final roll-out solar array. The Expedition 75 crew members completed final preparations for the spacewalk and also conducted biotechnology research.

  • Solar Flare Alert System Helps NASA Rocket Team Decide When to Launch

    For the first time, scientists have used NASA sounding rockets to study a solar flare in progress, thanks to a new flare alert system that told the team when to launch. Solar flares accelerate particles and release energy into the solar system, which can affect Earth and its technologies. Sounding rockets are a relatively fast, […]

  • NASA-Funded SSPICY Mission Experiences Communications Loss

    A NASA-supported small satellite launched in October as a technology demonstration has lost contact with its owner and operator, Starfish Space. NASA and Starfish have concluded the spacecraft is not recoverable due to an issue preventing communications between the SmallSat and ground operators. Led by Starfish Space, NASA’s Small Spacecraft Propulsion and Inspection Capability (SSPICY) […]

  • Crew Keeps Up Spacewalk Preps, Research, and Cargo Operations

    CSA (Canadian Space Agency) astronaut and Expedition 75 flight engineer Joshua Kutryk is pictured during a spacewalk with his spacesuit's helmet visor down to install a new roll-out solar array on the International Space Station's port side truss structure. The orbital outpost was soaring 267 miles above the South Atlantic Ocean at the time of this photograph.

    Expedition 75 is continuing preparations for the second and final spacewalk in a series of two to upgrade the International Space Station’s power generation system. The orbital residents are also conducting microgravity research and transferring cargo in and out of a U.S. cargo spacecraft.

  • NASA’s Eyes software: October release notes

    On October 28, 2026, a new version of Eyes on Exoplanets was released. This release added the new Nancy Grace Roman Space Telescope, which is expected to find thousands of new exoplanets. When accessing Eyes on Exoplanets from your mobile phone, you can use the augmented reality feature to place the spacecraft in your own […]

  • Week Starts with Spacewalk Preps and Life Science

    NASA astronaut and Expedition 75 flight engineer Anil Menon points his camera toward his spacesuit’s helmet visor and takes an out-of-this-world “space selfie.” Menon participated in a spacewalk with CSA (Canadian Space Agency) astronaut Joshua Kutryk to install a new roll-out solar array on the International Space Station's port side truss structure.

    Preparations continue for the second in the final series of spacewalks to upgrade the International Space Station’s power generation system on Thursday. Meanwhile, the Expedition 75 crew focused its research efforts on life science at the beginning of the week.
