Nasa Apollo 13 Notebook Sells For £248,000 At Auction

The careful calculations made after that famous phrase, "Houston, we have had a problem," was uttered by Commander James Lovell, have sold for £248,000 at auction.

The Apollo 13 notebook, part of a sale of the possessions of retired NASA commander Lovell, 83, was crucial in guiding the astronauts safely back to earth after problems arose in spacecraft's command module.

On the third day of the Apollo 13 mission, an oxygen tank exploded, making the command module uninhabitable.

The astronauts retreated to the lunar module as their “lifeboat,” as seen in the film Apollo 13.

Lovell's life-saving calculations identified the crew's position in space, and helped them return safely to earth.

“They found out they had minutes to get from commander module to the lunar module or they were going to die,” said Howard Weinberger, a senior space consultant at Heritage Auctions in Dallas told ABC News.

The notebook sold to a private collector form the U.S.
