The title pretty much summarizes the question.
Weirdly, googling „dawn spaceprobe burn time“ and similar things didn‘t turn up anything useful (at least for me), so I was wondering if maybe someone here knows how long dawn‘s xenon reserves lasted?

1$\begingroup$ @Jake It's always okay to answer your own question n SE, but it's important to make it a good quality answer, so I've move your link back into your post where it belongs, and included a block quote of the numbers so if the link rots the information is still available in the answer, thereby preventing it from being a link-only answer. $\endgroup$– uhohFeb 24, 2021 at 23:38
