Hap McSweenCanadian Broadcasting Corporation Radio, as part of its Mars coverage, re-released a documentary about Terraforming Mars, which featured UT’s Harry “Hap” McSween. The piece examines a massive geo-engineering project of making the dry and barren Red Planet into an Earth-like new home for humanity. McSween noted that terraforming is closer to science fiction than science, and that everything from poison soil to political resistance could prevent it from ever happening. Listen to the podcast here.

McSween, distinguished professor of earth and planetary sciences, is a leading expert on the composition of Mars.
