2 tesla Magnetic Shield placed at Mars Lagrange point would shield Martian atmosphere for affordable partial terraforming
An inflatable structure(s) can generate a magnetic dipole field at a level of perhaps 1 or 2 Tesla (or 10,000 to 20,000 Gauss) as an active shield against the solar wind and allow the Martian atmosphere to thicken overtime. Mars atmosphere would naturally thicken over time, which lead to many new possibilities for human exploration …
