Why we should send humans to Mars?
The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration. Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind.
Can we send humans to Mars?
For a start, the sheer distance. Astronauts bound for Mars will have to travel about 140 million miles (225 million kilometers), depending on where the two planets are relative to each other. That means a trip that’s many months long, where astronauts will face two major health risks: radiation and microgravity.
Why we shouldn’t move to Mars?
The consequence of this lack of protection is a longer exposure to these rays which are deadly to the human body. Astronauts living on Mars would be subject to 50 times more radiation than humans living on Earth. This amount of radiation can create dangerous cancers.
What are the problems with going to Mars?
“[The] greatest dangers include the risk of prolonged cancer and its effects due to exposure to both interplanetary radiation (during Mars transit) and surface radiation (during extended surface stay).
What do astronauts do all day?
The station crew spends their day working on science experiments that require their input, as well as monitoring those that are controlled from the ground. They also take part in medical experiments to determine how well their bodies are adjusting to living in microgravity for long periods of time.
What is a year on Mars called?
Martian days are called sols—short for “solar day.” A year on Mars lasts 669.6 sols, which is the same as 687 Earth days. Mars’ axis of rotation is tilted 25 degrees with respect to the plane of its orbit around the Sun.
