Pick up the free 55 minute documentary of NASA's most dramatic ever mission this weekend in The Sunday Times.

13th April 1970, on route to the Moon, Apollo 13 developed life-threatening problems, prompting the famous words "Houston, we've got a problem". More than 200 thousand miles out in space, an oxygen tank exploded, ripping off a side of the service module and disabling the Odyssey spacecraft.

Astronauts James Lovell, John Swigert and Fred Haise had reached the point of no return. To get back safely, the astronauts had to orbit the moon and sling themselves on the correct trajectory back to Earth. All of America watched, waited and prayed for their safe return while scientists, engineers and fellow astronauts created a rescue plan.

The film depicts Appollo 13's dramatic explosion and how a voyage of scientific exploration turned into a matter of survival and one of the Apollo Programme's finest moments. This mission didn't get to be one of glory, but it did turn out to be a glorious rescue.
