Watch On
On Episode 172 of This Week In Space, Rod Pyle and guest host Rick Jenet are joined by Erika Alden DeBenedictis to discuss how terraforming Mars might work.
If we’re ever to make Mars a second home, we have some serious housekeeping to do… as in a total renovation. The Red Planet has little atmosphere, no radiation shielding, and some seriously toxic soil. How can we make it more Earthlike… and should we?
Dr. Erika Alden DeBenedictis joins us to discuss how terraforming might work, how it could be done in decades instead of millennia, and the questions surrounding the ethics of changing another planet to suit humanity’s needs. We say it’s a trailer park of a planet, but the best bet for human expansion.
Dr. Rick Jenet is this week’s co-host. Join us for the conversation!
