On April 13, 1970, an explosion crippled the Apollo 13 spacecraft, threatening to doom its three astronauts to a certain death 200,000 miles from Earth. After several days of intense analysis and feverish activity in the U.S., when the final crunch came the day before the spacecraft had to return to Earth, NASA still needed the answer to one critical mathematical equation in order to bring the crew home safely. Now for the first time, we learn that NASA sought that answer from only one source: the University of Toronto Institute for Aerospace Studies. Dr. Roderick Tennyson gives readers a first-person account of how he and his fellow UTIAS aerospace scientists came up with the answer in less than eight hours.
