Among the mountainous dunes and small, undulating ripples of Mars' desert-like surface are sand structures, intermediate in size, that are not quite like anything on Earth.
Stanford University scientists have now used an AI model to analyze a million Martian dunes and uncover how these sandy waves form on our sister planet at a scale - roughly 1 meter between crests - that previously seeme Soyuz leak cancels space station spacewalk

Webb glimpses field of extragalactic PEARLS, studded with galactic diamonds Russian ISS spacewalk cancelled due to coolant leak: NASA

A spacewalk by two Russian cosmonauts aboard the International Space Station was called off after the detection of a coolant leak, NASA said on Thursday.
The Russian space agency, Roscosmos, said that a walk in space by Sergei Prokopyev and Dmitry Petelin had been cancelled after one of the warning indicators went off in the Soyuz spacecraft docked to the ISS.
The mission had been planned for Wednesday.
NASA said that a coolant leak had been discovered "from the aft end of the Soyuz MS-22 spacecraft", towards the back of the vessel.
"NASA and Roscosmos will continue to work together to determine the next course of action following the ongoing analysis," the US space agency said.
"The crew members aboard the space station are safe, and were not in any danger during the leak."
US astronaut Frank Rubio flew to the ISS with the two Russian cosmonauts on the Soyuz rocket, which launched on September 21 from Kazakhstan.
Space has been a rare avenue of cooperation between Moscow and Washington since the start of Moscow's assault on Ukraine in February, and ensuing Western sanctions on Russia that shredded ties between the two countries.
