Momentum / Reaction Wheels[edit]

I'm not sure about the description of Momentum Wheels, the description sound more like Reaction Wheels i.e. the spacecraft rotates in the opposite direction of the motor rotation - an equal an opposite reaction. Momentum wheels spin constantly and give much finer control with minimal backlash. In fact they spin faster-and-faster over time and have to be regularly "unloaded" using thrusters. The 3-axis gyroscopic effect gives the spacecraft more inertial mass - it appears stiffer and heavier to turn, making steering more accurate.

Solar sails[edit]

Shouldn't it be Mariner 10 instead of Pioneer 10?

Relative/Absolute sensors[edit]

The given definition of relative and absolute sensors is quite unclear for me. For example gyroscope, from the relative sensors cathegory, does not essentialy rely on any other external objects or phenomena. Yet sun sensors, from the absolute sensors cathegory, depend clearly on observed object and output relative information about measured attitude. Therefore I am quite confused. --Robert Valner (talk) 01:07, 4 February 2013 (UTC)

I suggest merging all of spin-stabilized satellite into the more general article attitude control. (I am mystified as to why this was first suggested at Talk: flight dynamics (spacecraft)#Merge from spin-stabilized satellite and 3-axis stabilized spacecraft ). --DavidCary (talk) 02:59, 12 June 2014 (UTC)
