[Apollo 13]

A VIEW OF "THE LOST MOON" SIGNED AND EXTENSIVELY INSCRIBED BY CREW AND CAPCOM.

Apollo 13, meant to be the third mission to land humans on the moon, ran into trouble when damaged wire insulation ignited in an oxygen tank and vented the contents of both oxygen tanks in the Command Service Module Odyssey. Though the crew made it safely back to Earth, the landing was canceled, and this view from their Lunar Module "lifeboat" during their lunar flyby is as close as the Apollo 13 astronauts got during the mission. They had precious few moments to observe the lunar surface up close before heading back to earth. The shut-down Command Module is visible out the overhead rendezvous window.

The “PC+2 Burn” referenced in LMP Fred Haise’s inscription refers to the pericynthion + 2 burn. This burn was executed with the Descent Propulsion System of the Lunar Module Aquarius, an engine that was originally planned to help them land on the Moon. Approximately two hours after this photograph was taken on the crew's closest approach to the Moon, Haise completed a larger burn to shorten their return trip time by 10 hours. This maneuver saved them more electrical power, cooling water, and breathable oxygen to survive the voyage home. 

CAPCOM Jack Lousma’s lengthy inscription also refers to their efforts to survive in the damaged spacecraft by moving to the Lunar Module Aquarius, which the crew treated  as a lifeboat.
