Terra: Original science programming on the web

A guy I knew from work went to Montana State U's Science & Natural History Filmmaking school a few years back. He put his thesis project "The Search for Life on Mars" on Terra, which is how I first heard of this video podcast site. Terra programming is devoted to science and the environment.

Terra is produced by MSU and Filmmakers for Conservation Ltd. and runs on TV in Montana PBS, but also runs these shows online in entirety. Many of the films were student projects from MSU--but keep in mind, this is the training ground for many of the filmmakers that go on to work for the Discovery Channel and National Geographic. Lucky us, because their online portfolio includes full-length, high-quality productions on interesting topics for free. Case in point: The Story of Stuff.
