Guide To Space: Spacecraft Gyroscopes And Reaction Wheels. You Can Never Have Enough

<p><a href= "https://www.youtube.com/watch?v=mvVgGh7uiEg">https://www.youtube.com/watch?v=mvVgGh7uiEg</a></p> <p><strong>From Aug 13, 2019.</strong></p> <p>It’s amazing to think there are telescopes up in space, right now, directing their gaze at distant objects for hours, days and even weeks. Providing a point of view so stable and accurate that we can learn details about galaxies, exoplanets and more.</p> <p> </p> <p>And then, when the time is up, the spacecraft can shift its gaze in another direction. All without the use of fuel.</p> <p> </p> <p>It’s all thanks to the technology of reaction wheels and gyroscopes. Let’s talk about how they work, how they’re different, and how their failure has ended missions in the past.</p> <p> </p> <p>Scott Manley’s Aug 20, 2018 clip:<span class= "Apple-converted-space"> </span></p> <p>Scientists May Have Figure Out Why So Many Spacecraft Were Failing</p> <p><a href= "https://www.youtube.com/watch?v=KibT-PEMHUU&t=0s">https://www.youtube.com/watch?v=KibT-PEMHUU&t=0s</a></p> <p> </p> <p>We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.<span class= "Apple-converted-space"> </span></p> <p>Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p>Share the podcast with your friends and send the Patreon link to them too!<span class="Apple-converted-space"> </span></p> <p>Every bit helps!
