Has there been any talk of further fly-by targets? I seem to recall there were a number of possible candidates after the Pluto fly-by, but I suppose the Thule visit might have ruled some or all of those others out.
To be clear, something that "doesn't last long" on an astronomical timescale could still quite happily exist stably for several dozen human lifetimes.
"And we hope to hunt down one more KBO — one more Kuiper Belt object — and make an even more distant flyby in the 2020s," Stern added [...] New Horizons [...] has enough juice [...] to keep the power on through the mid to late 2030s, he said.”
Lets hope.
