Fast forward twenty years, and a second expedition to Mars is launched.
They did get some pictures of Mars's surface and would have sent a second mission earlier, but apparently some pesky World War III got in the way.
Not to worry, this is just fiction. Right?
So this second expedition consists of eighteen spacemen and twenty-three other men. New technology allows for a nineteen day crossing. Guess they figured they could survive without women for a month or so. We'll see about that.
Captain van Tromp sends back three rather interesting messages. None of them are about hills being alive.
The first says there are no survivors from the Envoy (told ya). The second claims there is alien life on Mars. The third is a correction: turns out there is one Envoy survivor. (Talk about outwit, outlast, outplay.)
