If NASA can actually do this then by 2030 we will have all the data needed to mass produce space reactors (for propulsion, electrical power, mining, whatever) which would permit serious space exploration in the later 2040s and 50s. By "serious" I mean off-earth laboratories with triple-digit populations, such as a lunar particle accelerator or a venus orbiter which would build up for a true mars shot - itself just step one for a larger program to chart Jupter's and Saturns many moons. By that point we'll have information from JUICE vis-a-vis conditions on Europa, and this would allow for an in-depth Europa chemical analysis program to discover off-earth life. Ideally, by that point we'll have a regular schedule of rockets coming to and from other planets that we can just slot missions into.

And if we can successfully do that, we could build something like a giant 100m telescope outside the asteroid belt, creating optimal conditions for observing Alpha Centuari for an inevitable probe there that would have to be nuclear-powered somehow.
