Human Space Colony On Mars Would Be Awful Idea, ESA Chief Says – International Business Times

Living on Mars would not be as rad as people think. The head of the European Space Agency himself doesnt seem too keen on becoming a Martian immigrant, based on what he said at this week'sU.K. Space Conference in Manchester, England.

If you go to Mars you cannot go outside for a small walk, ESA director general Johann-Dietrich Wrner told the TimesWednesday. Always you have to be sheltered and covered, but you cannot even bring your dog to the next tree. Mars is not nice.

During a conference that also featured speakers like former International Space Station astronaut Tim Peake, astrophysics professors and space company founders, Wrner emphasized the difference between visiting a planet and inhabiting one. Humans will fly to Mars, for sure. Humans will fly to the moon again, for sure. But colonization that always sounds to me as though we should leave the Earth. And I hope that we will not leave the Earth in the next 3 billion years, but that humans will find a way to secure life on Earth.

The idea of securing life on Earth clashes with the words of another authority on space: Stephen Hawking. The astrophysicist, who has been known for making extreme statements and predictions about the future of humanity, is warningif humans want to survive extinction, they will have to start a space colony within the next 100 years. He says the species will not survive the next millennia on our planet.

But Wrner told the Times living on Mars or the moon would be no replacement for Earth: This is something like, We destroyed everything, so lets go to a better place.But you will hardly find a better place.

But at least in the foreseeable future, a colony in space or on a planet like Mars would not be a pleasant place, the head of the European Space Agency warns. Photo: NASA

Space agencies and companies are advancing space technology, learning more about how microgravity and long trips affect the human body, how to grow crops in space and how to make space travel more sustainable. Beyond simply visiting and exploring other planets and moons, there is a push to start up a human colony somewhere, with SpaceX founder Elon Musk being one of the most vocal advocates. Mars is the most popular destination, with the moon not trailing far behind. There are also the possibilities of moons in the outer solar system and planets orbiting other stars.

But even if the technology catches up to those dreams, that doesnt mean it will be pleasant. Wrner gave Earths closest neighbor, the moon, as an example: Would you like to stay in a place where half of the month its dark and half of the month theres sun? That is the moon. No. To stay for two weeks in darkness, thats not a nice life.

Mars has better lighting but the other conditions are not much better. It has a thin atmosphere, after losing much of its air to outer space, so breathing outside is out of the question. With barely any atmosphere, dangerous radiation from the sun also beats down on the Red Planet.

And while temperatures have at times been as warm as a spring day, its record-low surface temperature is -190 degrees Fahrenheit. Plus its a dusty, rocky and dry planet.
