NO they can't it is to cold to live there
Yes
Unless you live in a space housing environment specially created for human live on Mars, you would need a space suit to live on Mars, just as you would on the Moon. Mars has very little atmosphere, the temperatures are usually very cold. There is a good possibility of being hit by solar radiation. Mars has no life on it that we know of, and a human being would probably die, if they tried to live there without protection from a well designed, enclosed building, or a space suit.
Without a spacesuit, airtight building or other breathing apparatus, a human could live for about 3 minutes on Mars. With the right equipment, a human can live indefinitely on Mars.
Mars is the most Earth-like of all the planets in our solar system (not including Earth itself). While it would certainly not be easy for human beings to live on Mars, it would nonetheless be easier for human beings to live on Mars, than it would be for them to live on Mercury, Venus, Jupiter, Saturn, Uranus, or Neptune. So in terms of interplanetary colonization, Mars seems to be the best bet.
Because Mars does not have an atmosphere suitable for human life.
Yes
It would be challenging for earthlings to live on Mars due to factors such as the thin atmosphere, lack of breathable air, extreme temperatures, and radiation exposure. Significant advancements in technology and infrastructure would be needed to sustain human life on the planet.
It would be very challenging for a human to survive on Mars without significant technological support. Mars has a thin atmosphere, little oxygen, extreme temperatures, and high levels of radiation that would make it difficult for humans to live there long-term. Additionally, the lack of food, water, and breathable air would make sustaining life on Mars very difficult.
the human will die beacause there is no air on mars
As of now, Mars is not suitable for human habitation due to its harsh environment, lack of breathable air, and extreme temperatures. However, there are proposals for potential future missions to establish human settlements on Mars.
It is currently not possible for people to live on Mars due to the lack of essential resources such as air, water, and food. However, there are ongoing missions and research by space agencies like NASA to study the possibility of human colonization on Mars in the future.
