In October 2018, The Mars Society announced that it was holding a special contest

called, “The Mars Colony Prize” for designing the best plan for a Mars colony

of 1000 people. There would be a prize of $10,000 for first place, $5,000 for

second and $2500 for third. In addition, the best 20 papers would be published in a

book - “Mars Colonies: Plans for Settling the Red Planet.”

This is that book. The 580 page greyscale softcover edition and the color ebook

edition are now on sale at Amazon, other online sites, and can also be ordered

through your local book stores.
