These two bits of paper with notes hastily scrawled across them are actually part of the emergency checklist that helped save the crew of the doomed Apollo 13 space mission. Astronauts marked the cards with critically important instructions after an explosion crippled their craft, prompting the famous 'Houston, we have a problem' line.
The record is a real time step-by-step account of how the crew set about powering down the craft in order to conserve enough power for them to get back to Earth. Jim Lovell, Fred Haise and Jack Swigert all survived the 1970 mission, which was later made into Hollywood blockbuster Apollo 13 starring Tom Hanks.
The emergency power down checklist was kept by Fred Haise for years afterwards and has now come to light for the first time after being made available for sale. Described as an 'amazing part of space history', it comes with a letter of provenance from Mr Haise and is expect to sell for up to £50,000.
Apollo 13 was Nasa's third space mission to the moon, but two days after the launch it suffered an oxygen tank explosion which lead to a loss of power, oxygen and heat.
