Khan and eighty-four of his fellow Augments leave Earth aboard the SS Botany Bay, not to be heard or seen from again, until the mid-23rd century:
Project Khan ends research on 06.07.96. A funding report is published on June 7, 1996. It would be one of Adam Soong's few surviving works after Kore Soong hacked into her father's computers and deleted all his research. (PIC: "Farewell")

Notes[]
According to show runners, Spock was wrong and the Eugenics Wars happened much later during 21st century. Terry Matalas: "We discussed endlessly. We came to the conclusion that in WW3 there were several EMP bursts that kicked everyone back decades. Records of that 75 year period, the '90s on were sketchy. Maybe Spock was wrong? No easy way to do it if you want the past to look and feel like today." In response to Khan's own references to the 1996 date, that they simply have be ignored to make the series more relatable to the present; " Maybe because in 1967 they didn't anticipate the show still going for another 6 decades." Aaron J. Waltke added: "There's also the ripples of the Temporal Cold War shifting the Prime Timeline in Enterprise – at least until the Temporal Accords put an end to that wibbly wobbliness." [1]
According to the Star Trek Encyclopedia, 3rd ed., p. 290 & 657, the Sands Hotel in Las Vegas is closed on June 30 and Earth scientists discover microscopic evidence of ancient life on Mars by studying a Martian meteorite.
