..everywhere we go we have to dump waste. Here is the first step to an ocean/mountain of waste. It's not even our planet and we are already polluting it.

Reply to Realistically speaking When do you think we will land humans on Mars? by EnaGrimm

how far is Mars?

What is our fastest ship?

Mars is 84.000.000 Km. away from us.

The fastest ship we have was Apollo 10. 39.000 Km/Hr. (with no human in it.) A human will not survive speeds over 6000Km/Hr. (we think.)

So, there we go.

84.000.000Km (away) / 39.000 Km./Hr.(speed) = 2154 Hr / 24 (hour in a day)= ...?.. (days on the way)

84.000.000Km./6000Km.Hr.=14.000Hr./24=584Days. About 19 months.

There is your answer.

BUT?
