NASA's Curiosity rover faced an unexpected challenge during a recent sampling attempt on the Martian surface.
An international team of astronomers has determined that the Milky Way's star-forming disk ends around 35,000 to 40,000 light-years from the galactic center. Using stellar age mapping, they found a U-shaped pattern where star formation drops sharply beyond this boundary. Stars farther out are mostly older migrants drifting from inner regions.

Thales Alenia Space has acknowledged a manufacturing issue affecting habitation modules for NASA's former Lunar Gateway project. The company stated it will fix the problem, described as a 'well-known metallurgical behavior,' by the end of the third quarter of 2026.

Blue Origin achieved a milestone by successfully landing and reusing the first stage of its New Glenn rocket for the third flight, but the upper stage failed to place its payload into the correct orbit. The launch occurred Sunday from Cape Canaveral Space Force Station in Florida. The booster, named Never Tell Me The Odds, touched down on a ship in the Atlantic Ocean after its second flight.
