[Science] FUSE

Very cool stuff! The FUSE satellite is using the magnetic field of the Earth for stationkeeping...

I am very interested in this because I did 3 years worth of Science Fair projects on this topic ["Can the Magnetic Field of the Earth be Used as a Feasible Form of Space Vehicle Propulsion? I-III"] where I concluded (back in 1992-93) that it could be used for station keeping.

I was laughed at by my college physics professor. Well screw him, I was right. :-)
