“It would be great some day to have astronauts in a rover on Mars. But just about anyone except an oil company executive would say its more important to have 50 million solar powered vehicles in the United States.” -Brad Sherman
Is terraforming a real possibility for Mars? It seems like one of the most inhospitable places we could have asked for: cold, small, barren, devoid of liquid water, with only a thin atmosphere, and with soil that’s toxic to terrestrial lifeforms. Yet Mars was once a wet, thriving planet, teeming with all the potential for life that an early Earth once possessed.
Could it get there again? It’s certainly a more daunting task than any environmental crisis we can envision taking place on Earth, since we’d pretty much have to add an enormous amount of atmosphere to Mars to make it habitable. Even if we could, the atmosphere would be stripped away by the solar wind… but that might not be a dealbreaker!
