Harrison Schmitt credits the image to the entire Apollo 17 crew. While on the Moon's surface, Schmitt — the only geologist in the astronaut corps — collected the rock sample designated Troctolite 76535, which has been called "without doubt the most interesting sample returned from the Moon". Among other distinctions, it is the central piece of evidence suggesting that the Moon once possessed an active magnetic field. As he returned to the Lunar Module before Cernan, Schmitt is the next-to-last person to have walked on the Moon's surface. After the completion of Apollo 17, Schmitt played an active role in documenting the
Honduras lunar sample displays 10 by 14 inches, consists of one "moon rock" particle specimen that was cut from lunar basalt 70017. This basalt was collected by Apollo 17 astronaut Harrison Schmitt on the moon in 1972. Once lunar basalt 70017 was brought back to earth from the moon, the basalt moon rock was cut up into small fragments of approximately 1 gram each.
