Lunar Surface Sensing Probe Removal Tag
lm_probe_tag1000
  • This Grumman Removal tag indicates that the Lunar Surface Sensing Probe had been installed on a Lunar Module, “Vehicle No. 39.” This was LM-9, an early LM design originally intended for the Apollo 15 flight. LM-9 was replaced for Apollo 15 with LM-10, a more advanced design which could carry more equipment, including the Lunar Roving Vehicle.
  • The reference designator block is overwritten by carbon ink from the date written on the back of the card. But removing these characters reveals the reference designator “-Y,” indicating that this sensing probe had been installed on the left landing gear (when facing forward in the LM).
  • The back of the tag indicates a weight of 2.55 lbs. Its current weight of 2.52 lbs probably results from the lack of a cover plate on the switch access port.
