Do we need manned space flights? Show more Show less

Seeing a man on the moon was one of the coolest things of the 1960's. Since then, shuttle have been sending many, many people up to complete missions. These are costly and incredibly dangerous. Are manned missions economically viable or is it more effective to focus on less expensive drone missions?

No, space flights are too dangerous Show more Show less

The risks of a manned expedition are too high to make it viable

Astronauts in interplanetary travel will be engaged on a trip of several months, which will isolate them for the rest of mankind

The Argument

A return trip to Mars is currently projected to last 26 months (6 months of travel, 14 months on Mars waiting the correct planter alignment for the return trip). This is far more than average stay on Internatiol Space Station (ISS). Further in case of an emergency an immediate return to Earth is possible form ISS which will not be the case for a Mars expedition
