That 7 second video of a small rocket shot into a cloud to induce a lightning strike (about half way down the article) is incredible.

Any ideas why the lightning strike appears mostly green (and momentarily purple and orange)?
Soooo you are telling me that we still haven't fully understood something as fundamental as lightning and it's still an active area of research...
So, nothing new?
The cosmic ray hypothesis has been dominant for a few years now.

Tl;dr lightings may be caused by electrons/positrons from outer space hitting a cloud and initiating an "avalanche" of electrons.
just in case you missed it, all matter carrys a charge, and all space(and matter) has energy radiating through it, making the universe an energy gradient.
sometimes you can see it happening.
