SIGN UP ⋅   WEBSITE   The Launchpad Happy Monday space fans! It's a busy day as we get underway to bring you all things space news and science. Mark your calendars as tomorrow is the second shortest day in history, thanks to the Earth spinning slightly faster. It'll only be faster by 1.34 milliseconds less than the standard 24 hours — not something you'll notice — but it's part of a puzzling trend in Earth's rotational behavior that has been unfolding in recent years. Other stories for today include South Korea planning to build a moon base by 2045, two NASA Mars probes preparing for launch on Blue Origin's huge New Glenn rocket, and a new "This Week in Space" podcast episode all about the 60th anniversary of Mariner 4.  We have all that and more for your daily read.  Thanks for exploring with us.
