Havia 8 pessoas no Envoy, a missão original (primeira parte, ch I):
Captain Michael Brant, commanding—pilot, astrogator, relief cook,
relief photographer, rocketry engineer;
Dr. Winifred Coburn Brant, forty-one, semantician, practical nurse,

Três deles são contabilizados (parte I, ch IV):
“It’s a nasty story. I got that much before my informant sobered up.
Dr. Ward Smith delivered his wife by Caesarean section—and she died on
the table. What he did next shows that he knew the score; with the
same scalpel he cut Captain Brant’s throat—then his own. Sorry, hon.”
Jill shivered. “I’m a nurse. I’m immune to such things.”
“You’re a liar and I love you for it. I was on police beat three
years, Jill; I never got hardened to it.”
“What happened to the others?”
“If we don’t break the bureaucrats loose from that log, we’ll never
know—and I am a starry-eyed newsboy who thinks we should. Secrecy
begets tyranny.”
Tanto quanto eu posso dizer, não há mais menção aos outros cinco tripulantes. Não é uma resposta muito satisfatória, mas aí está. A menos que Heinlien tenha respondido em algum outro local, o destino do restante da equipe de Envoy permanece desconhecido.
