Space Science Updates: Key Developments in Satellite Technology and Polar Discoveries

NASA has indefinitely postponed a mission to reposition an aging satellite using robotic spacecraft developed with Katalyst, citing weather and technical difficulties. The orbital-grappling technology demonstration was meant to advance commercial satellite servicing and compete with Chinese space capabilities. Meanwhile, Amazon's Leo broadband network has grown to over 390 satellites following a Florida launch and plans to offer internet services later this year as part of a 3,200-satellite global coverage initiative.

Researchers have determined why Antarctica froze 34 million years before the Arctic, with the South Pole developing an extensive ice sheet while the Arctic remained ice-free for another 25 million years. The discovery advances understanding of polar climate history. Separately, Indian startup Skyroot Aerospace is preparing to launch Vikram-1, the country's first privately developed orbital rocket.
