Science News Roundup: Scientists identify 37 recently active volcanic structures on Venus; SpaceX capsule carrying NASA astronauts slated for August 2 return and more

The research focused on ring-like structures called coronae, caused by an upwelling of hot rock from deep within the planet's interior, and provided compelling evidence of widespread recent tectonic and magma activity on Venus's surface, researchers said on Monday.

Scientists identify 37 recently active volcanic structures on Venus

Scientists have identified 37 volcanic structures on Venus that appear to be recently active - and probably still are today - painting the picture of a geologically dynamic planet and not a dormant world as long thought. The research focused on ring-like structures called coronae, caused by an upwelling of hot rock from deep within the planet's interior, and provided compelling evidence of widespread recent tectonic and magma activity on Venus's surface, researchers said on Monday.

SpaceX capsule carrying NASA astronauts slated for August 2 return

The NASA astronauts who traveled to the International Space Station in SpaceX's first crewed flight in May are expected to return to Earth on Aug. 2 after spending two months in orbit, a NASA spokesman said on Friday. U.S. astronauts Bob Behnken and Doug Hurley will gear up for the final benchmark test of SpaceX's so-called Demo-2 mission: a coordinated splashdown somewhere in the Atlantic Ocean that will cap NASA's first crewed mission from U.S. soil in nearly a decade.
