TechRepublic transformed one of its most popular stories, NASA shows the world its 20-year virtual reality experiment to train astronauts, in to an audio story. It's like getting a free mini audiobook in your podcast feed.

NASA's Johnson Space Center told TechRepublic's Erin Carson the whole story behind one of the most important tools it uses to train astronauts: virtual reality. Read the cover story, and learn how the agency pulled off VR's greatest triumph.

We've taken the story and turned it into an audio story and made it available for free in the feed of The TechRepublic Podcast (subscribe via RSS or iTunes). You can also listen directly in the embedded player below.
