Question: how long do you think it would take humans to go to mars

Heidi answered on 16 Nov 2019:

The travel time itself isn’t too long, probably about 8 months in total, but that time varies. Because Mars and Earth are both orbiting the Sun at different speeds, you would want to launch your rocket at the right time, to minimise how long the journey is!
But, realistically, we probably won’t be going to Mars for at least a decade or two!
