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

https://www.youtube.com/watch?v=mvVgGh7uiEg From Aug 13, 2019. 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.   And then, when the time is up, the spacecraft can shift its gaze in another direction. All without the use of fuel.   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.   Scott Manley’s Aug 20, 2018 clip:  Scientists May Have Figure Out Why So Many Spacecraft Were Failing https://www.youtube.com/watch?v=KibT-PEMHUU&t=0s   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
