Not really the first time, but they seem to be much closer to be being able to study them. Apparently, they had 38 atoms trapped for miliseconds. Now it's time to prove it behaves just like matter.
The plume issue is not that difficult. I think they used something similar on Apollo LES. The problem is stabilizing the entire system, which is extremely difficult. The entire system will most likely plummet down after the solar balloon phase (which is the only phase they tested before). At least they are not using government money :).
