Spock/Legacy

Though brought up to embrace a Vulcan way of life that he would eventually commit to as a young man, Spock's encounter with V'ger had a profound impact on his personal philosophy. From that point forward, Spock began to further embrace his human half and more readily explore the influences and impacts of human emotion, though he continued to temper his outward expressiveness.

Spock's self-sacrifice to save the Enterprise from Khan formed the basis of Starfleet's The Needs of the Many holographic training drill, while the rescue of his resurrected self from the Genesis Planet was the basis for the Escape from Spacedock drill. Both simulations were in use by 2381. ()

After reaching Federation Headquarters in 3189, a year after her arrival from 2257, Michael Burnham learned of her brother's achievements and viewed a recording of Spock talking to Jean-Luc Picard. Despite Ni'Var's separation from the Federation, Burnham's status as Spock's sister opened the chance for her to negotiate for the SB-19 data. () While onboard the , Burnham stared nostalgically at the science station and commented to Cleveland Booker that it had been her brother's station on the USS Enterprise. ()
Spock's legacy further extended into the alternate reality. It was he who located New Vulcan, a new homeworld for the Vulcans following the loss of their old one. () Following his death, alternate reality Spock originally planned to resign his Starfleet commission and continue the work the ambassador began on New Vulcan. However, after seeing a photograph of the prime reality Enterprise crew that was among old Spock's personal effects, alternate Spock changed his mind, having come to the conclusion that for now, his destiny lay with his crewmates.
