Biomedical Science and Hardware Top Thursday’s Schedule


The Expedition 74 trio aboard the International Space Station checked out ultrasound gear, inspected advanced sample processing hardware, and tested muscle-stimulating electrodes on Thursday.

Shortly after NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft arrived to Launch Pad 39B at the agency’s Kennedy Space Center in Florida on Jan. 17, engineers began preparations for an upcoming wet dress rehearsal, a fueling test of the rocket set to occur before launch. Technicians hooked up purge lines meant to keep cavities of […]

Sound and hearing studies as well as Earth observations kept the Expedition 74 trio busy on Wednesday. The International Space Station residents also worked on cargo transfers, downloaded radiation data, and kept up lab maintenance.

Microbiology research to protect astronaut health and spacecraft hardware topped the science schedule aboard the International Space Station on Tuesday. Earth observations and life support maintenance rounded out the day for the Expedition 74 trio.

The small satellites passed a crucible of tests, ending with a simulation of the intense vibrations of launch. When the six tiny spacecraft of NASA’s SunRISE (Sun Radio Interferometer Space Experiment) mission settle into their orbits high above Earth after launching later this year, they’ll function as one giant radio dish to track the rumbles of radio bursts coming from deep within the Sun’s atmosphere, or corona. Those bursts are generated by solar energetic particle events that could in extreme […]

The Sun emitted a strong solar flare, peaking at 1:09 p.m. EST on Jan. 18, 2026. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured video of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft […]

Editor’s Note: The timeframe for a wet dress rehearsal has been updated. At 6:42 p.m. EST on Saturday, Jan. 17, NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft reached Launch Pad 39B after a nearly 12-hour journey from the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. Hours earlier, NASA’s […]

The SLS (Space Launch System) rocket and Orion spacecraft that will carry four astronauts around the Moon is rolling to Launch Complex 39B at NASA’s Kennedy Space Center in Florida. The four-mile trek began at 7:04 a.m. EST on Saturday, Jan. 17, and is expected to take up to 12 hours. The 11-million-pound stack has been undergoing preparations […]

The four crew members of NASA’s SpaceX Crew-11 mission have arrived at the agency’s Johnson Space Center in Houston, where they will continue standard postflight reconditioning and evaluations. As part of Crew-11, NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov safely splashed down […]

NASA’s Scientific Balloon Program has completed four successful Antarctica flights during a long-duration campaign that began in early December. The balloons launched from the agency’s facility located near the U.S. National Science Foundation’s McMurdo Station on the Ross Ice Shelf. The General AntiParticle Spectrometer (GAPS) balloon lifted off Dec. 15. The GAPS payload is an experiment designed to detect anti-matter particles entering Earth’s atmosphere to help reveal the origin of dark matter — an invisible […]
