A spacecraft in flight cannot help but change the space about it – which can pose problems. A new paper in the Journal of Geophysical Research: Space Physics presents a study on how ESA’s Jupiter Icy Moons Explorer, Juice, is interacting with the solar wind. The consequences include potentially problematic surface charging, a dense cloud of photoelectrons that surround the spacecraft and a more than 65-m-long wake of ion-free space behind it, resembling the trail of a boat.

A volunteer crew recently "returned" from a simulated 45-day mission to Mars at NASA's Johnson Space Center (JSC) in Houston. The crew completed their stay in a small habitat, contributing to research essential for future human space missions to the Moon and Mars. The HERA (Human Exploration Research Analog) missions are part of NASA's effort to study how humans cope with the unique challe

Is our home galaxy, the Milky Way Galaxy, a special place? A team of scientists started a journey to answer this question more than a decade ago. Commenced in 2013, the Satellites Around Galactic Analogs (SAGA) Survey studies galaxy systems like the Milky Way. Now, the SAGA Survey just published three new research articles that provide us with new insights into the uniqueness of our own Milky Wa

Mars wasn't always the cold desert we see today. There's increasing evidence that water once flowed on the Red Planet's surface, billions of years ago. And if there was water, there must also have been a thick atmosphere to keep that water from freezing. But sometime around 3.5 billion years ago, the water dried up, and the air, once heavy with carbon dioxide, dramatically thinned, leaving only
