Sawyer Rosenstein hasn't exactly glided through life: At the age of 12, a confrontation with a locker-room bully left him paralyzed and dealt a heavy blow to a promising acting career. But his love of space exploration sustained him through surgery after surgery, and earned him a place on the Talking Space podcast team. It's in that capacity that he attended this month's final space shuttle launch, and his uplifting essay about the experience appears today on the Boing Boing website. "Don't tell me the sky is the limit when there are footprints on the moon," he writes. It's well worth a read, even if you're less of a space fan and more of a fan of triumph over adversity.
