Watch a Mesmerizing Animation of NASA Satellites \u2013 (Wired \u2013 March 9, 2015)<\/a><\/b>
\nNASA\u2019s Earth-observing satellites get the dubious honor of staring at us all day. Now, this video of the fleet zipping around the planet\u00a0is\u00a0just mesmerizing enough to make us want to do the same. Roughly 400 miles overhead in low-Earth orbit, these 18 spacecraft are constantly taking pictures and collecting data about Earth, from its climate and oceans to its deserts and forests. They circle the planet once every hour and a half, totaling about eight orbits in the 12 hours elapsed in the animation. Look closer and you\u2019ll notice that most of these flyers orbit Earth in the north-south direction\u2014that\u2019s called a polar orbit. It\u2019s one of the most useful orbits for exploring a planet, moon, or any other planet-like body, because it lets the satellite see the entire surface while the planet rotates below.<\/p>\nA FINAL QUOTE–<\/b><\/p>\n
Tomorrow is the most important thing in life. Comes into us at midnight very clean. It’s perfect when it arrives and it puts itself in our hands. It hopes we’ve learned something from yesterday.<\/em>— John Wayne<\/p>\nA special thanks to<\/strong>: Larry Dossey, Chas Freeman, Ursula Freer, Sergio Lub, Diane Petersen, Gary Sycalik, Steve Ujvarosy and all of you who have sent us interesting links in the past.
