Rosetta Zoo comparison image

Today, ESA and the Zooniverse launch Rosetta Zoo, a citizen science project that invites volunteers to engage in a cosmic game of 'spot the difference'. By browsing through pictures collected by ESA's Rosetta mission, you can help scientists figure out how a comet's surface evolves as it swings around the Sun.

Long-duration space flight alters fluid-filled spaces along veins and arteries in the brain, according to new research from Oregon Health & Science University and scientists across the country.

The study published today in the journal Scientific Reports.

"These findings have important implications as we continue ," said senior author Juan Piantino, M.D., assistant professor of pediatrics (neurology) in the OHSU School of Medicine. "It also forces you to think about some basic fundamental questions of science and how life evolved here on Earth."

The research involved imaging the brains of 15 before and after extended tours of duty on the International Space Station.

Researchers used imaging to measure perivascular space—or the space around blood vessels—in the brains of astronauts prior to their launch and again immediately after their return. They also took MRI measurements again at one, three and six months after they had returned. Astronauts' images were compared with those taken of the same perivascular space in the brains of 16 Earth-bound control subjects.

Comparing before and after images, they found an increase in the perivascular spaces within the brains of first-time astronauts, but no difference among astronauts who previously served aboard the orbiting earth.

Blown by wind across continents and oceans, dust does more than make skies hazy, congest lungs, and leave a film on windshields. Also known as mineral dust or desert dust, it can influence weather, hasten snowmelt, and fertilize plants on land and in the ocean. Particles from North Africa can travel thousands of miles around the globe, sparking phytoplankton blooms, seeding Amazonian rainforests

We have cleared the "Greenheugh pediment" and the mix of sandy, steep, and rough terrain that challenged our drives up and down it. However, we are finding that as we make our way up Mount Sharp along a new route, some of the same driving gremlins are with us. Yesterday's drive made it just about all the way to its endpoint, but Curiosity encountered higher than expected tilts as she attem

DARPA is seeking proposals for Phases 2 and 3 of the Demonstration Rocket for Agile Cislunar Operations (DRACO) program for the design, development, fabrication, and assembly of a nuclear thermal rocket engine. The goal is to execute an in-space flight demonstration of nuclear thermal propulsion in fiscal year 2026. The overall objective of DRACO is to enable time-critical missions over va

One of the prime objectives of the Perseverance mission is to collect a diverse cache of rock samples for eventual return to Earth. Among the highest priority rocks to sample are those that make up the well-preserved delta located on the western side of Jezero crater. This delta was one of the key attributes that made this landing site so appealing for the search for ancient Martian life.
