THE EARLY SUN WAS FAR MORE VOLATILE THEN IT IS NOW.

THIS COMBINED WITH LARGE IMPACTS DESTROYED ITS ATMOSPHERE.

IF WE WHERE TO GIVE MARS A ATMOSPHERE AT PRESENT IT WOULD LAST MILLIONS IF NOT BILLIONS OF YEARS

FULL TERRAFORMING IS UNNECESSARY AND STUPID

WE ONLY NEED TO RESTORE ENOUGH ATMOSPHERE SO THAT WE MAY WALK OUTSIDE WITH A OXYGEN MASK.

WE CAN DO THIS AT PRESENT WITH RELATIVELY TINY INVESTMENT.

MARS IS ON THE BORDER OF EXPERIENCING A RUNAWAY GREENHOUSE EFFECT DURING THE SUMMER THAT WOULD RELEASE MASSIVE AMOUNTS OF FROZEN CO2 AND WATER VAPOR INTO THE ATMOSPHERE IF TRIGGERED.

THIS WOULD GIVE MARS 30 TO 40% OF OUR ATMOSPHERE AT SEA LEVEL WHICH IS MORE THEN ENOUGH FOR HIGH ALTITUDE PLANTS TO SURVIVE AND EASY TO CONSTRUCT DWELLINGS AND GREENHOUSES.

THIS WOULD ALSO ALLOW US TO WALK ON THE SURFACE OF MARS WITH ONLY A JACKET AND A OXYGEN MASK.
