As spacecraft and rovers at Mars emerge from solar conjunction – a period when the Red Planet and Earth are on opposite sides of the Sun and contact with Mars missions isn’t possible – NASA has resumed efforts to recontact its MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft using NASA’s Deep Space Network and the […]
The next astronauts to fly around the Moon went into quarantine late Friday. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen, will ensure that they don’t pick up any illness that could delay their mission by limiting their exposure to others in the days before […]
Cardiac research and artificial intelligence were the main science topics for the Expedition 74 crew on Friday. The International Space Station also received an orbital boost when the SpaceX Dragon spacecraft fired its engines at the end of the week.
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 […]
