The risks involved with space exploration include: micrometeorites – danger from impact damage (to spacecraft and to astronauts during spacewalks) solar flares and radiation – danger from ionising radiations. no atmosphere – we need air to breathe.

Why space exploration is bad?

Astronauts and space tourists face risks from radiation, which can cause illness and injure organs. Researchers used supercomputers to investigate the radiation exposure of an historical space mission. Improved computation times could one day model astronaut radiation exposure in real time.

Can dragon land on land?

Initially, SpaceX did hope to land its spacecraft on terra firma. And instead of using parachutes, CEO Elon Musk hoped Crew Dragon would use its engines to slow its descent — using what's called a propulsive landing. ... Throughout history, crewed spacecraft have safely touched down at sea and on dry land.
