	Gyroscope - Wikipedia, the free encyclopedia
		A gyroscope is a device for measuring or maintaining orientation, based on the principle of conservation of angular momentum.
		The gyroscope effect was discovered in 1817 by Johann Bohnenberger and invented and named in 1852 by Léon Foucault for an experiment involving the rotation of the Earth.
		Gyroscopes can be used to construct gyrocompasses which complement or replace magnetic compasses (in ships, aircraft and spacecraft, vehicles in general), to assist in stability (bicycle, Hubble Space Telescope, ships, vehicles in general) or be used as part of an Inertial guidance system.

	Gyroscope
		The gyroscope was invented in 1852 by the French experimental physicist Leon Foucault (1819-1868) as part of a two-pronged investigation of the rotation of the earth.
		His gyroscope was a rapidly rotating disk with a heavy rim, mounted in low-friction gimbals.
		The gyroscope is spun up to speed with arrangement on the left-hand side, where the cranked wheel is in contact with a small wheel on the axis of the rotor.

	Howstuffworks "How Gyroscopes Work"
		Gyroscopes can be very perplexing objects because they move in peculiar ways and even seem to defy gravity.
		These special properties make gyroscopes extremely important in everything from your bicycle to the advanced navigation system on the space shuttle.
		The Russian Mir space station used 11 gyroscopes to keep its orientation to the sun, and the Hubble Space Telescope has a batch of navigational gyros as well.

	Gyroscope (Site not responding. Last check: )
		The classic image of a gyroscope is a fairly massive rotor suspended in light supporting rings called gimbals which have nearly frictionless bearings and which isolate the central rotor from outside torques.
		At high speeds, the gyroscope exhibits extraordinary stability of balance and maintains the direction of the high speed rotation axis of its central rotor.
		If a gyroscope is tipped, the gimbals will try to reorient to keep the spin axis of the rotor in the same direction.

	Spaceflight Now \| Delta Launch Report \| The GP-B experiment
		Gyroscopes, or any spinning object, remain oriented in the same direction as long as they are spinning, a property called rotational inertia.
		If a perfectly-spherical, spinning gyroscope floated above the Earth in spacetime, and it was protected from external forces that could re-orient it (e.g., gravity, solar radiation, atmospheric friction, magnetic fields, electrical charges), and all internal imbalances were removed (e.g., imperfect shape, unbalanced density, surface imperfections) it would remain pointing in its original direction.
		If the local spacetime in which the gyroscope was floating was curved or was twisting, the gyroscope's position would change to follow this curve or twist.

	Exhibit Cross Reference - Gyroscope
		This gyroscope, unlike most others, allows the addition or subtraction of angular momentum because of its two wheels.
		When the wheels are spun in the same direction, their combined motion add, when spun oppositely, they can cancel if spun to the same speed.
		When the gyroscope is spun up and the sliding weight set for no precession (in the middle), the exhibit can be moved aroung the museum floor and it will not change its spatial orientation (much).

	Gyroscope Experiment 1 (Site not responding. Last check: )
		To determine the movement of a gyroscope when one end is fixed in space, with rotational freedom, and the other end free to roam.
		To determine if the turning of the free end of the gyroscope is biased on the gyroscope, both ends will be tested to make sure that there is no mechanical reason for the turning.
		It is apparent that the turning of the gyroscope is based on the spin direction of the bottom part of the flywheel, and slightly downwards.

	8th Div Coldwar
		When deployed to Germany in 1957 as part of Operation Gyroscope it was believed that the division would remain there for three years.
		Operation Gyroscope was a plan that was initiated after World War II to cut down the expense of replacing men for overseas duty.
		Officers and enlisted men who were then assigned to the division were given the opportunity to volunteer for Gyroscope provided they had sufficient time left during their current tour.

	SPACE.com -- Shuttle Astronauts Repair ISS Gyroscope in Second Spacewalk
		During the gyroscope replacement, the spacewalkers played what Noguchi has called an "orbital shell game," placing the broken gyroscope in a holding area, plucking out its replacement from a berth in Discovery's payload bay and sliding the faulty unit into that same berth.
		Control moment gyroscopes are vital components for the International Space Station (ISS), allowing the orbital laboratory the ability to change its orientation while conserving propellant by not firing its Russian-built thrusters.
		Flight controllers powered down one of the station's working gyroscopes, CMG-3, while Discovery is docked at the ISS after some abnormal vibrations led them to suspect the massive load was putting too much of a strain on it.

		Using vibrations from the antennae, which remain in fixed positions during flight, the organ can detect when and where the moth's body moves in relation to its antennae.
		In essence, it is behaving much like a gyroscope on a ship or plane that gives the vehicle a frame of reference to move within.
		Further investigation revealed the Johnston's organ then sends this information to the brain so the moth can shift its body back to the correct position.
