The astronauts collected a record 108.86 kilograms of lunar rocks, including some that were orange in color, during their three moon walks and drives through the Taurus-Littrow Valley.
The last three scheduled Apollo missions had already been cancelled because of budgetary shortfalls by the time of this flight. The astronauts left behind a plaque that read:
"Here Man completed his first exploration of the Moon, December 1972 A.D. May the spirit of peace in which we came be reflected in the lives of all mankind."
