Tipping Point (noun)
• The critical point in an evolving situation that leads to a new and irreversible development
• An addition or increment that, in itself, might not seem extraordinary but that unexpectedly is just the amount of additional change that will lead to a big effect

Tipping Point (noun)
• The critical point in an evolving situation that leads to a new and irreversible development
• An addition or increment that, in itself, might not seem extraordinary but that unexpectedly is just the amount of additional change that will lead to a big effect
There are many Level-4 Electric Propulsion Technologies that are at a tipping point.
Electric Propulsion as a whole is in the process of tipping.
Small input will yield disproportionately large displacement.

The EP Roadmap: Scaling
Straightforward (adj): admitting no doubt or misunderstanding; having only one meaning and leading to only one conclusion.
Easy (adj): capable of being accomplished with ease; posing no difficulty
vs.
GapsProvide technology gaps that the roadmap did not cover
Potential Gap: Ground testing and development
• In order to thrive EP technology programs must be active at prime contractors, small businesses, and multiple academic institutions
• At present high-power EP will be ‘choked’ at 1, 2, or 3 available ground facilities• Some roadmap technologies will severely strain national xenon production capabilities, not to mention cost of raw material• NASA must consider alternatives to all-xenon architectures – what are they and what are the trades?
