No. Mars has a weak magnetic magnetic field which is incapable of containing an atmosphere that would support us. It also took Earth over 1 billion years for atmospheric oxygen to accumulate in significant amounts.
- CydeWeys 7y agoWith active terraforming you could accumulate an atmosphere much more quickly than over the course of a billion years. We're currently adding a measurable amount of carbon dioxide to the Earth's atmosphere every year, which isn't great here, but would help tremendously to terraform Mars.
