This mass redistribution alters Earth&#8217;s center of gravity, which in turn speeds up and slows down the planet&#8217;s spin\u2014and so the length of the day\u2014as well as changing the orientation of its spin axis. These changes to Earth&#8217;s spin and orientation occur over relatively short timescales of days and weeks, and threaten communication between ground stations and missions in orbit and across the solar system.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-03-track-spacecraft-earth.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Keeping track of spacecraft as Earth&#8217;s water alters its spin<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mass is constantly being redistributed around our planet, as Earth&#8217;s atmosphere, oceans and other bodies of water on and under the surface melt, shift and stir.
