AS16-P-5436 shows Kuiper a little bit beyond (to the right) of the frame's centre (scroll to the right).
AS16-P-5441 also shows Kuiper (scroll to the right, beyond the frame's centre).
WARNING: the LPI's so-called stereo companion of frame 5441 (frame 5346) shows a totally different part of the moon's surface!

An unnamed crater south of Kuiper?

There seems to be a circle-shaped formation (or rather: the remains of a circle-shaped formation) south of Kuiper. See SLC-map E5 (System of Lunar Craters, 1966). The WAC Nearside - Big Shadows version of the ACT-REACT Quick Map (LROC) shows just a more-or-less arc shaped system of wrinkle ridges... My investigating eyes can't detect a circle-shaped formation. - DannyCaes Feb 18, 2017


  • Named for Gerard Peter Kuiper (December 7, 1905 - December 23, 1973), a Dutch-American astronomer. He was blessed with an extraordinarily sharp eyesight, allowing him to see magnitude 7.5 stars with the naked eyes, about four times fainter than visible to normal eyes. Kuiper discovered two moons of planets in the solar system, namely Uranus's moon Miranda and Neptune's moon Nereid. In addition, he discovered carbon dioxide in the atmosphere of Mars and the existence of a methane-laced atmosphere above Saturn's moon Titan in 1944. Kuiper also pioneered airborne infrared observing using a Convair 990 aircraft in the 1960s. Kuiper spent most of his career at the University of Chicago, but moved to Tucson, Arizona in 1960 to found the Lunar and Planetary Laboratory at the University of Arizona. In the 1960s, Kuiper helped identify landing sites on the Moon for the Apollo program. The Kuiper belt, Asteroid 1776 Kuiper, the Kuiper crater on the Moon, craters on Mars and Mercury, and the now-decommissioned Kuiper Airborne Observatory were named in his honor.

  • This replacement name for a formerly lettered crater was introduced on LTO-76D2 (for which it served as the chart title). - Jim Mosher

  • Page 135: Venus breathes in steady fashion (New Scientist, 1973).

It's a bit strange to come across Kuiper in VENUS-related articles. One should expect the appearance of his name in lots of moon articles. I went through all 701 pages of Mysterious Universe, but... detected Kuiper on only two pages... - DannyCaes Apr 26, 2015
