Among them, 553 have circled the planet, 24 beyond the orbits of most satellites. Twelve have walked on the moon. These travelers share something exceedingly rare in the human experience: a planetary perspective of our home. In the 1986 Challenger disaster, veteran astronauts Francis Scobee, Judith Resnik, Ellison Onizuka, and Ronald McNair were killed alongside first-time astronauts Michael Smith, Gregory Jarvis, and Christa McAuliffe, who never reached space and are not represented here.
