Since Marc Garneau is leaving politics, I can now share how, before his historic first orbital flight in 1984, his assignment to the mission faced hostility from NASA astronauts.
However, his military background and dutiful ways overcame this frosty reception.
In our country, he's known as the first Canadian astronaut. But on that 1st flight, he was a payload specialist, not considered a full-fledged astronaut but a passenger or guest scientist. And that created resentment from the crew.
