Additional Information

  • Depth data from Kurt Fisher database
    • Viscardy, 1985: 0.56 km
  • An LTVT measurement of the shadows in LO-V-75M suggests the depth is closer to 430 m. The diameter also appears to be 2.75 km, a bit larger than the IAU value. - JimMosher JimMosher
  • The little crater just outside the SW rim of Collins is about 650 m in diameter and 130 m deep. This crater was part of the Apollo Landmark Tracking program, in which Command Module pilots took sextant readings on selected targets. These were later reduced to absolute selenodetic coordinates based on the position of the Command Module as determined by radio triangulation from Earth. From Apollo 10, John Young pointed his sextant at rockslide in the northeast quadrant of the 650 m crater, while from Apollo 11, Michael Collins (for whom the larger crater was later named), used as his target a tiny craterlet just inside the north wall. Neither that crater nor the rockslide are evident in this LO-V medium resolution view. And although there is a higher resolution view available (LO-V-078H), the area in which these tiny targets lie is unfortunately marred by development flaws. Nonetheless, what looks like an 80 m diameter craterlet can be seen near the top of the north rim. Its LTVT-determined coordinates are 1.305°N/23.628°E
  • Since this LTVT result is based on the same master image used to register the higher resolution views of crater West, it is possible to make a test of the consistency of two systems of selenodetic coordinates. According to Wollenhaupt et al., the correct location of Michael Collins's tiny target crater (known as target 130"/11) in the Mean Earth/Polar Axis lunar coordinate system is (1.26 +/- 0.02)°N / (23.66+/-0.01)°E, indicating that the LTVT reported values need to be corrected by -0.04 degrees in latitude and +0.03 degrees in longitude. Given the uncertainty of 0.01 to 0.02 degrees in the landmark tracking results, this is quite consistent with the corrections that need to be applied to the LTVT readouts (based on the much less precise 1994 ULCN) to give the Apollo 11 Laser Ranging Retroreflector (LRRR) its correct position in the detailed views. This means that at least in this small area of the Moon the Apollo Landmark Tracking and LRRR experiments gave consistent results, and produced coordinate systems that are offset from the 1994 ULCN by the same amount.- JimMosher JimMosher

  • Named for Michael Collins (October 31, 1930-living), an American astronaut who flew on Gemini 10 and Apollo 11, where he served as the command module pilot. While he orbited the Moon, Neil Armstrong and Buzz Aldrin performed the first manned landing on the lunar surface.
  • This replacement name for a formerly lettered crater was among the list of 12 names of living astronauts and cosmonauts (six each) approved by the IAU in 1970 and published in Menzel, 1971.
  • A peculiar "zigzag"-shaped cluster of craterlets immediately south-southwest of Collins (Sabine D) seems to have been nicknamed The "Z" during the heydays of the first manned lunar landing, see LPOD Monday Morning Quarterbacking, 4 decades later.
  • The small elongated cluster of depressions immediately northeast of Collins was nicknamed Chain Gulch during the heydays of Project Apollo, see Phil Stooke's LPOD US-1 and Other Signposts.
