“Houston, we’ve had a problem…”

Forty years after the Apollo 13 mission, Universe Today takes a look at the missions, the accident and how the astronauts got back to earth safely: 13 Things That Saved Apollo 13 (Link via MetaFilter: Surviving a Space Scrape 40 years Ago.)
So far, nine of the 13 parts have been posted. (I’m going to add the other links as the pages become available.)

Gene Kranz was the flight director for NASA‘s Gemini and Apollo Missions. Here’s a Discovery Channel Video of Kranz talking about his experiences with the Apollo 13 mission. I’m reading Kranz’s book Failure is not an Option: Mission Control from Mercury to Apollo 13 and Beyond right now and enjoy it immensely.
