If future Mars colonizers want to survive without pressure suits, they’ll need to generate a denser atmosphere. One way to achieve this could be to bombard the Red Planet with water-rich asteroids.

One part of this plan would require increasing the planet’s atmospheric pressure, and one scientist suggests that capturing celestial objects from the Kuiper Belt—which are full of the necessary light ...
