Blood Moon: Diagrams explain how eclipses work. Space.com has a big page of more information about blood moons, lunar tetrads (NASA video), a calendar of the four lunar eclipses 2014-15, and a great downloadable infographic called Shadow on the Moon that sums all this up in graphic form! Most of this will be valid for the next three eclipses as well! Going in Astronomy.
The phases of the April 14-15 total lunar eclipse are shown with GMT timestamps in this NASA image from a video guide. The total lunar eclipse will affect two NASA spacecraft orbiting the moon since they rely on sunlight for power.
