NASA’s Apollo program sent 24 humans from the Earth to the moon between 1969 and 1972. All were white male Americans. Five of them are still alive, including Buzz Aldrin, the lunar module pilot of Apollo 11, which made the first landing. All are in their 90s. Since then, no human, Canadian or otherwise, has left the realm of low-Earth orbit where the ISS flies, a mere 400 kms away.
