Aroundtrip to mars is expected to take up to 2 years and this would be dangerous to human health. true or false

do you mean that instead of a rover or rocket sending people there in a rocket. well if its people your sending then i guess its true kind of because its along period of time and whle in space you are be stretched little by little. but not really because if they have enough suppllies to hold them and there doing task while heading their keeps them active and moving. but you do stretch alil by lil so i guess true

True

Explanation:

One way trip to mars will take anywhere between 150-300 days depending on the alignment of Mars-Earth and the speed of launch. The round trip will easily be of around 2 years. For this whole journey the astronaut will be in micro-gravity environment and out of the safety of Earth's atmosphere. The gravity is very critical for a healthy person and long exposure to micro-gravity environment will have its adverse effects on astronauts.

Astronauts will also be exposed to a lot of radiation which is blocked by atmosphere on Earth. This exposure is very dangerous and long exposure to such radiation might be cancerous as well.

Not to forget the adverse psychological impact on Astronauts from the long journey.

the closer the planet is to the sun, the larger the gravity
