Could 2 NASA astronauts be stuck at the space station until next year? A decision is imminent

Will two NASA astronauts return to Earth soon in their troubled Boeing capsule? Or wait at the International Space Station for a ride home next year with SpaceX?

NASA has been wrestling with that decision ever since Butch Wilmore and Suni Williams arrived at the orbiting lab in early June on what was supposed to be a weeklong test flight.

Researchers identify effective materials for protecting astronauts from harmful cosmic radiation on Mars

Researchers have identified specific materials, including certain plastics, rubber, and synthetic fibers, as well as Martian soil (regolith), which would effectively protect astronauts by blocking harmful space radiation on Mars. These findings could inform the design of protective habitats and spacesuits, making long-duration Mars missions more feasible. Because Mars lacks Earth's thick atmosphere and magnetic field, astronauts exploring the planet would be exposed to dangerous levels of radiation.

Dimitra Atri, Investigator, Center for Astrophysics and Space Science and Group Leader of the Mars Research Group at NYU Abu Dhabi's Center for Astrophysics and Space Science, and lead author Dionysios Gakis from the University of Patras in Greece, report these new findings in "Modeling the effectiveness of radiation shielding materials for astronaut protection on Mars," appearing in the journal The European Physical Journal Plus.

Comparing two proposed NASA missions to Jupiter's moon Io

Thanks to NASA's Juno mission to the Jupiter system, we're getting our best looks ever at the gas giant's volcanic moon Io. Even as Juno provides our best views of the moon, it also deepens our existing questions. Only a dedicated mission to Io can answer those questions, and there are two proposed missions.

Io is well-known as the most geologically active world in the solar system, and it's not even close.

Juice JANUS view of the Moon

Since ESA’s Jupiter Icy Moons Explorer (Juice) flew by the Moon and Earth earlier this week, we’ve seen images from its monitoring cameras and we’ve seen images from its navigation camera. Today we reveal the first images from its scientific camera, JANUS, designed to take detailed, high-resolution photos of Jupiter and its icy moons.

NASA said Thursday it will decide this weekend whether Boeing's new capsule is safe enough to return two astronauts from the International Space Station, where they've been waiting since June.
