As Astroscientists, we are going to challenge that claim.]]> 2017-08-12 14:17:42 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/180803521 len_halprin https://padlet.com/len_halprin/33e577tjpifu/wish/180803522 The background image is a 1970s proposal for a large, man-made, slowly-rotating colony located at the L-5 point in space, complete with gardens, trees and rivers, and capable of supporting thousands of inhabitants.]]> 2017-08-12 14:17:42 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/180803522 https://padlet.com/len_halprin/33e577tjpifu/wish/181164791 2017-08-15 22:49:07 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181164791 https://padlet.com/len_halprin/33e577tjpifu/wish/181165260 Even though it is nothing to do with a physical form of transport, hydroponics would be an extremely good source of fresh food. One kind of hydroponics uses nutrients from fish [waste] to make the plants grow, while the plants filter and freshen the water.

But this could be solved! If a colony ship ventured to a moon or planet such as Jupiter's moon Encladeus that has water [including ice] on or in it, we could send either probes or "big" pipes down to the surface, based on the size, gravity and atmosphere of the object.]]> 2017-08-15 23:11:24 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181166402 https://padlet.com/len_halprin/33e577tjpifu/wish/181167338 The south African city of Durban relies on its own peoples urine as clean water. in Melbourne, we also do have the facilities to recycle urine to use as drinking water but the need for it doesn't exist yet. this might be the technology used for space as well. ]]> 2017-08-15 23:22:26 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181167338 https://padlet.com/len_halprin/33e577tjpifu/wish/181168340 Because the gravity on space station is "alterable", the possibility of gravity-propelled perpetual motion and energy generators [such as a turbine] is feasible. ]]> 2017-08-15 23:35:41 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181168340 https://padlet.com/len_halprin/33e577tjpifu/wish/181168880 2017-08-15 23:42:47 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181168880 https://padlet.com/len_halprin/33e577tjpifu/wish/181169088 When we live on another planet, all of the things that we produce will have to be recycled. just throwing out our waste will be something that we could't do. ]]> 2017-08-15 23:45:05 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181169088 https://padlet.com/len_halprin/33e577tjpifu/wish/181169444 Apart from turbines, things such as solar panels and waste fuel could provide power on an off-world colony.]]> 2017-08-15 23:49:02 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181169444 https://padlet.com/len_halprin/33e577tjpifu/wish/181169850 Nuclear propulsion — rockets powered by nuclear reactions — could be a more efficient way of taking supplies to the station, but that kind of technology isn't advanced enough to use currently.]]> 2017-08-15 23:54:30 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181169850 https://padlet.com/len_halprin/33e577tjpifu/wish/181169865 Nuclear propultion rockets powered by nuclear reactions — could be a more efficient way of taking supplies to the station, but that kind of technology isn't advanced enough to use currently.]]> 2017-08-15 23:54:38 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/181169865 https://padlet.com/len_halprin/33e577tjpifu/wish/182208725 We believe that living somewhere else in our universe is a possibility. It may take 100 years or it might take 1000 years, but it is possible. Because there are problems now, we need to take action and try to find a solution because no one is listening and we need to at least gather people and find a way to fix our current earth and save mankind. We suggest that we try to keep our current Earth livable, but the nations of the world do need to take action and develop the technologies and infrastructure that humans require to survive indefinitely in space, in the case of our planet "dying", and we should do it sooner rather than later because we don't want to start when its too late.]]> 2017-08-22 22:27:43 UTC https://padlet.com/len_halprin/33e577tjpifu/wish/182208725
