My idea to Terra form Mars
1.Create a massive solar shield about 5 million miles away from mars to shield the planet from the solar winds. Only would have to be a few miles wide if done right.
2. Set up ion fusion powered storage ships. Yep, about 500 of these that can hold 10,000 pounds of atmosphere each. Have them sweep through the venus atmosphere collecting the atmosphere and dumping it into mars atmosphere. After about 100 years of constantly dropping atmosphere onto mars = more atmosphere for mars.
3. At the same time as dumping atmosphere from Venus also create another 1,000 or more plants to convert carbon from the surface into more co2.
4. After a few hundred years bring over grasses, Moses and other hardlity planet life in order to convert co2 into oxygen.
5. After that make nitrogen.
As we're doing so build cities on the planet so we're personally on the surface.
