How Hubble Points - It's Not Thrusters

Рет қаралды 16,571

Күн бұрын

How Hubble points is a really interesting question. Instead of thrusters, Hubble uses a sophisticated system of reaction wheels and magnetic torque rods (magnetorquers) to point itself from one target to the next. Hubble also uses rate sensing gyroscopes (gyros), fixed head star trackers (FHST), Sun sensors, magnetometers, and three fine guidance sensors (FGS) that allow Hubble to maintain ultra-steady pointing on a target for up to 24 hours at a time!

Legion of Weirdos I didn’t know what the magnetic torque rods were until I researched this video. I thought they were stability rods to maintain structural integrity during launch. The more you know...

I've wondered for the entire life of Hubble how it could work without thrusters, and didn't know exactly what a "reaction wheel" is. You're video gave me a satisfactory and gratifying explanation. Thank you.

thanks chris i didn't know about the magnetic torque bars what a brilliant idea thanks for the hubble update and the link... sorry i missed this video i never got a notification from youtube great reaction wheel demo in the classroom on how they work to turn hubble ... quality video thanks for posting it cheers james D

Thank you so much for the kind words! I am planning on talking about starshade in an upcoming video. While the channel is about astronomy, I'll probably end up tackling the challenges of interstellar travel at some point. Cheers!

I always wondered how it could take such long exposures of such distant objects. Doesn't the earth get in the way every orbit?

@LaunchPadAstronomy 5 жыл бұрын

In most cases, it does get in the way so the exposures are broken down into individual orbits and added together. Thanks for subscribing!
