Why should humans colonize space?
Humans have a right and a moral duty to save our species from suffering and extinction. Colonizing space is one method of doing so. Space colonization is the next logical step in space exploration and human growth. Technological advancement into space can exist alongside conservation efforts on Earth.
Why should we colonize other planets?
The primary argument calling for space colonization is the long-term survival of human civilization and terrestrial life. By developing alternative locations off Earth, the planet’s species, including humans, could live on in the event of natural or human-made disasters on our own planet.
Why do we need to go 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.
Why is Mars too cold to live on?
There are two main reasons that Mars is colder than Earth: it is farther from the Sun and it has an atmosphere that is too thin to retain heat. The Martian atmosphere contains greenhouse gases that would cause a much warmer surface if the planet had the gravity and magnetic field that would allow it to hold onto gases.
Why is it difficult to land on Mars?
The reason it is so hard to land on Mars is that the atmospheric pressure is low, less than 1\% of Earth’s surface pressure. This means that any probe will descend very rapidly to the surface, and must be slowed.
Why would it be difficult to live on Mars?
Humans cannot live on Mars because neither the temperature nor the atmosphere is compatible with human survival. There is also no edible food and very little available water. However, given the construction of an artificial environment, life on Mars could be possible. The Martian atmosphere is 95-percent carbon dioxide.
Why we should not go to Mars?
There are two main reasons for this: It would increase dramatically the risk of forward contamination of the Mars surface with our earthly microbes, which would ruin our unique chance to study a pristine Mars. All the reasons advanced to vindicate the act of Humans traveling to Mars are either wrong or can be addressed in a way that spares Mars.
