We don’t have the technology for terraforming Mars yet and turning this hostile planet into one that will support life, but there are some good ideas floating around.  One of the big problems with Mars is that it is basically a desert world, with a pitifully thin atmosphere less than 1 percent the density of Earth’s, so no animal can live on Mars and water quickly evaporates or freezes on the surface.  People have said that we could live in caves on Mars under the surface, if we are wearing space suits and that we could construct cities under glass.  Since the solar wind is responsible for depleting  Mars’ atmosphere, some scientists think that we could construct electromagnetic satellites to shield Mars’ atmosphere and this would prevent it from escaping into space.  Theoretically a giant magnetic shield could protect Mars from solar winds, and this would help terraform the Martian environment…
