I had some friends working on Hall Thrusters this summer at PPPL. Personally I'm rooting to see VASIMR-style thrusters get more use, but in general, plasma thrusters are really cool compared to chemical rockets.
Since I don't think this ever showed up in this thread, and Jonimus and I were marveling at it last night.

The above link is sobering.... In rocket-science terms they simply used a big-guns approach to escape gravity. However they used something akin to a calculator to get them home...
It was truly a modern day wonder and we are still reaping the benefits of the technological advances which were made during that decade...

Apparently they think they found a moon orbiting an exoplanet. If this is the case, this will be a first

Well, the blackhole bit is kind of cool, the bit about how densely packed that galaxy is is even more so!
