Avatars, embodied virtual beings, may be a vital too to combat loneliness & other complications tied to such journeys that require extreme isolation.
Immersive simulation could battle loneliness and improve mental health on long missions
“In the computing world, avatars are graphical representations of a user or that person’s alter ego. Through virtual reality technologies, these representations can take on 3-D forms so remarkably realistic that they could be the next best thing to physically having one’s relatives join them in space.” [excerpt from linked article, TMC.edu]
