A private space company from Scotland manufactures special satellites that can observe the glacial change from space and can make a lof for scientists who fight against global warming. I guess this is the space project we need. It`s easier to preserve our planet than spend millions of dollars on Mars`colonization missions.
For instance, we have the type of satellite the aim of which is observing glacial change from spce. This space project might help us control somehow the melting of icebergs and climate change, the problem that is really dangerous Earth. Also, there is such kind of satellites that aimed at observing mountains or even track some rare species of animals.
Last time when I`ve tried to post the link something went wrong. There is more information about the different uses of satellites and how useful they are for scientists to control some changes and help humans save Earth.
I think new users can't post links on their first few posts, you may be right. Welcome to the forums btw.
