Will space help humanity in the future?
Valuable Resources in Space
Space agencies have been collaborating for a long time, and they all agreed to use space for peaceful things and benefits to humanity.
Space helped greatly in the 1990s. Satellites helped communicate certain diseases in mosquitos, water, and agriculture throughout the world.
A robotic arm that was used to build the international space station was adapted into a smaller version that is used in surgery today. It was also adapted to go inside a imaging scanner to "assist with cancer diagnostics."
Many resources we use today are used to help create electrical wiring, drinking water, and to sustain life. A lot of these resources are non-renewable and are being used up very fast.
Some of these materials need to be extracted from very deep in the earth and cost a big effort to do so. Private companies are finding ways of going to space easier and using less money.
There are many planets, moons, and asteroids with a big variety of materials that we can use on earth. Going to these places to extract resources would help earth, but also humanity in the sense that we would be exploring as we go.
Humanity will eventually need to leave earth if we want our race to stay alive. It will not be an easy task to find a new earth, but scientists have already started looking.
Scientists have narrowed their search to rocky planets with liquid water. The planets have to be in the "habitable zone" which is basically the same distance away from earth to our sun.
CHEOPS and PLATO are both devices that can help find a new earth. They look at atmospheres and take pictures to further understand planets. Scientists will be able to detect chlorophyll on exoplanets within the next 20 to 30 years.
