question: The flags on the moon left by the U.S. manned Apollo missions are all still standing save for which mission's flag?
sentence: All of the U. S. flags left on the Moon during the Apollo missions were found to still be standing, with the exception of the one left during the Apollo 11 mission, which was blown over during that mission's lift-off from the lunar surface and return to the mission Command Module in lunar orbit; the degree to which these flags retain their original colors remains unknown.
