How does the HST 'aim' or 'steer'?

My googling abilities seem somewhat flawed today.

I was having a moon landing hoax debunking discussion with a few ill-educated morons on another site and the HST came up.

Of course we all know that it should be able to se the Apollo landing sites lol.

But anyway I digress. When called to point at a certain part of the sky, how does it manouver? Can it turn in any direction? To any position?


The Hubble Space Telescope uses gyroscopes to manouver. Their flywheels is spun up to high speeds and by turning the gimbals inertia makes the spacecraft move. All this is powered by electricity which the HST gets from its solar panels.

Hubble Site: Pointing

Hubble could be pointed at the moon. However, IIRC there’s an old thread on this, the resolution at that distance is about 100 yards per pixel.

What about the Harry S Truman? I suppose she just has a rudder. In port she would use tugs rather than bow-thrusters.

And I thought the OP was asking about the High Speed Train. That would have been an odd question. :slight_smile:

Believe me, I understand resolution and Dawes Limits.

And I thought HST was the accepted acronym.

Thanks fellas.

Hunter S. Thompson?

Hell, he could barely steer when he was alive!

I thought to myself, “Hypersonic Transport? they built one of those?”
