Reaction wheels are one way to make orientation adjustments without running the thrusters, and [Zachary Tong]’s liquid metal reaction wheel greatly simplifies the conventional design.

Most components don’t move much, but reaction wheels must spin thousands of times per second for years on end—so any imperfection can quickly produce catastrophic amounts of friction and heat.

One of the planet-hunting Kepler space telescope’s reaction wheels — devices that maintain the observatory’s position in space — remains balky despite mitigation attempts, NASA said April ...

Research from all publishers Recent studies have showcased the potential of chemical fuel-driven systems to achieve complex behaviours through well-engineered reaction networks.

One of Kepler's reaction wheels — devices that maintain the observatory's position in space — remains balky despite mitigation attempts.

Reaction wheels offer the advantage of running on renewable electricity from the orbiter's solar array, rather than drawing on the finite supply of thruster fuel.
