The new space race: Why we need a human mission to Mars
If we want to know if there is a life beyond Earth, the quickest way to answer this question is to explore Mars. This exploration is carried out by distant space probes sent from Earth.
The race, however, intends to send human explorers to Mars and a number of Earth-related projects trying to learn what life would be like on the red planet.
However, the notion of a single mission to human Mars is absurd, since the idea that we should colonize March simply because we are a disaster for the Earth.
The first suggestion is unnecessary and unethical, which astronauts envoyerions to their safe death, while the second would be a license to continue polluting our home planet.
I think we have to go to Mars, because of what we can learn from the red planet, and develop technologies to attract people there safely.
SpaceX contractor Elon Musk last September described his vision of a mission to send people to Mars in 2022. But first, he plans to send people around the moon.
The Moon is why humans have explored space, but sent probes to explore other planets in our solar system, including Mars.
Several unsuccessful attempts were made to send a probe to Mars, but US Mariner 4 was the first to successfully photograph another planet from space when it flew on Mars in July 1965.
Viking missions were the first to seek life on this planet, while others, such as the Spirit and Opportunity vehicles, which were separated in January 2004, tried to see if Mars had been living in the past.
No evidence of life was found so far, but the available techniques are now much more advanced and we know much more about the planet. We have abundant evidence of water on Mars.
The Advantages of Space Exploration
In addition to the search for life, why work to send humans to Mars? Many aspects of our modern life would not be possible if it were not our interest in space.
We rely on the satellites of communication, time and positioning. Satellites help protect us against time, especially in Australia.
Apollo and other NASA missions have spawned the evolution of micro-electrons that later became household appliances such as calculators and personal computers.
NASA has detailed more of the benefits derived from its research for space exploration, which even include dust brush.
The intangible but critical, however, is the inspiration we get from space exploration. This can be very important to attract young people in science and engineering, but it takes more of our economies continue to move towards an increasingly high technology future.
In the US, there has been an increase in science and engineering personnel in the Apollo to the Moon missions.
