Visiting Ceres in March

Not as dramatic as landing on a comet, but a first, just the same. In two months, NASA will orbit Ceres, the largest dwarf planet in the asteroid belt. The same craft has already orbited Vesta, the second largest. That will make it the first craft to orbit two celestial bodies. Plus, ion propulsion (Apr'15).
Doubleplus: 7 other space highlights expected this year
(May'15) Electromagnetic drives are tested and appear to work,  Puzzling though, do they violate Newton's third law?
