How high in the sky does the Hubble telescope orbit
How high in the sky does the Hubble telescope orbit? The answer is 375 miles, or 600 kilometers above the earth. How high in the sky the Hubble telescope orbits is not just determined by the initial flight however, because unlike other telescopes the Hubble is actually flown like a spacecraft.
The Hubble telescope has gyroscopes that help determine how far up in the sky the Hubble telescope orbits and where. These gyroscopes help the Hubble Space Telescope point itself in the right direction, acting like compasses that always point in the same direction (though in this case not necessarily north.) These Hubble gyroscopes have sensors that tell them that the telescope is moving at an angle, and act as reference points for the short term to help Hubble hone in on its targeted point, no matter how distant in the sky it must orbit to do so.
Another popular question is 'how much did the Hubble telescope cost for its Shuttle servicing mission'.
How far up in the sky does the Hubble telescope orbit can be determined, too, through the use of its reaction wheels. These steering mechanism for the Hubble Space Telescope spin in the opposite direction of the Hubble itself. Driven by the commands of specially designed flight software, the reaction wheels speed up or slow down their spin according to where they need to aim the Hubble telescope so that it can hone in on its next target.
The final determinant for how high in the sky the Hubble telescope orbits is its three sensors for fine guidance. These sensors find stars to guide themselves, measure the telescope's position in relation to these, and aim the Hubble by zeroing in on the location of these designated guidance stars.
