Evacuate Planet Earth The fate of the human race is in your hands…

Imagine if….. Scientists predicted that the surface of our beautiful planet was to disintegrate with in the next years. The surface would be overtaken by molten lava The seas would evaporate Plant and animal life could not be sustained FOR HUMANS TO SURVIVE WE WOULD HAVE TO LEAVE THE EARTH!

Its down to you to decide…. Its down to you to decide…. …..where we are going? To help you decide the worlds best scientists have come up with six possible options

What you can assume…. Assume that we do/will have the technology to create self sustaining bio spheres. In other words… Assume that we do/will have the technology to create self sustaining bio spheres. In other words… We can create structures to contain our own air, grow the food, generate heat and recycle the water we need to stay alive for a long time.

Option 1: The Moon

Moon Facts 384,400km from Earth 384,400km from Earth No atmosphere/air No atmosphere/air Exposed to meteorites Exposed to meteorites Water ice may be present at the poles Water ice may be present at the poles Temp -173 to 127C Temp -173 to 127C Humans have been on the moon Humans have been on the moon No magnetic field... Danger from the Solar Wind No magnetic field... Danger from the Solar Wind 1 moon day = 1 earth month 1 moon day = 1 earth month Gravity is one sixth the strength of gravity on earth Gravity is one sixth the strength of gravity on earth

Option 2: Mars

Mars Facts Closest temperature to the earth (still can get to -133C in winter Closest temperature to the earth (still can get to -133C in winter Thin carbon dioxide atmosphere Thin carbon dioxide atmosphere Length of a day is nearly the same as on earth Length of a day is nearly the same as on earth 5.25 earth months to travel there 5.25 earth months to travel there Gravity is about a third as strong as on earth Gravity is about a third as strong as on earth Mars is plagued by giant dust storms Mars is plagued by giant dust storms The frozen polar caps are mostly made of carbon dioxide but there may be a little frozen water too The frozen polar caps are mostly made of carbon dioxide but there may be a little frozen water too

Option 3: Venus

Venus Facts Nearly identical in size to the earth. May have similar composition Nearly identical in size to the earth. May have similar composition 3.5 earth months to get there 3.5 earth months to get there Dense carbon dioxide atmosphere: 90X the pressure of earths atmosphere Dense carbon dioxide atmosphere: 90X the pressure of earths atmosphere 25km thick cloud containing concentrated sulphuric acid 25km thick cloud containing concentrated sulphuric acid Average temp 467C Average temp 467C 1 Venus day= 243 earth days 1 Venus day= 243 earth days No magnetic field. No protection from solar wind. No magnetic field. No protection from solar wind.

Option 4: Jupiters Moon Europa

Why not Jupiter itself? 18 earth months away 18 earth months away Its the largest planet in the solar system but its a GAS GIANT Its the largest planet in the solar system but its a GAS GIANT It has no solid surface It has no solid surface It has a very strong magnetic field creating intense radiation belts that would kill you. It has a very strong magnetic field creating intense radiation belts that would kill you.

Europa facts Jupiters second largest moon Jupiters second largest moon Same size as our moon Same size as our moon May be the only other place in solar to have watery seas. May be the only other place in solar to have watery seas. Most of the water on the moon is frozen solid. Most of the water on the moon is frozen solid. No atmosphere No atmosphere Average temp -170C Average temp -170C

Option 5: Out of our Solar System

Out of our Solar System Facts Since 1995 we have confirmed the existence of at least 200 other planets out of our solar system Since 1995 we have confirmed the existence of at least 200 other planets out of our solar system Some predict that half the stars in our galaxy may have planets…..that makes 50 billion planets to choose from! Some predict that half the stars in our galaxy may have planets…..that makes 50 billion planets to choose from! Most planets found are gas giants but rocky planets are starting to be found. Most planets found are gas giants but rocky planets are starting to be found. The distance involved are unimaginably large. At current space travel speeds generations of humans would spend all their lives on spaceships. The distance involved are unimaginably large. At current space travel speeds generations of humans would spend all their lives on spaceships. In 2007 the first potential earth like rocky planet was found orbiting the star Gliese 581. This star is 20.5 light years away and in the constellation of Libra. With temperatures between deg it may have liquid water.

Option 6: Permanent Space Station/Colony orbiting Earth

Space Station Facts We may not need to leave earth altogether just its surface. We may not need to leave earth altogether just its surface. Earth could remain a good source of materials. Earth could remain a good source of materials. Unless we can generate artificial gravity systems we would have to live in weightless conditions Unless we can generate artificial gravity systems we would have to live in weightless conditions The man made problem of space junk The man made problem of space junk
