Left: Overhead view by LO-IV-154H The brightly lit ridges above and below the center of this image are the north and southwest rims of Malapert. Because the Sun strays just 1½ degrees north and south of the Moon's equator, craters at high latitudes are always seen at low sun angles, and their floors are in perpetual darkness.
Middle: Infrared temperature map from the Diviner instrument on LRO, with the principal IAU names. The area between [/Haworth Haworth] and [/Nobile Nobile] does not appear to be regarded as part of Malapert. Topographic maps of the [/south%20pole south pole] are helpful for understanding the relative depths of these features.
Right: Earth-based radar view by Campbell et al. When the librations are favorable, the Moon's south pole can tip towards Earth by more than 7 degrees. Hence, as shown here, radar waves transmitted from Earth can illuminate more of Malapert's floor than can sunlight (note: in the LPOD image from which this has been cropped, the Earth-based radar data was re-mapped to a north-up aerial view).

- Although it is not mentioned in the LPI's search-list of orbital Apollo photographs, the crater called Malapert WAS photographed during the mission of Apollo 15. It was captured near the central part of the upper margin of frame AS15-95-12988 (near the terminator). Malapert could be the most southern crater which was once photographed during the Apollo project. A High-Resolution scan of AS15-95-12988 is needed!

Additional Information

  • The lunar peak on Malapert's southwest rim, assigned the name Malapert Alpha in [/Whitaker%2C%201954 Whitaker, 1954], has been widely touted (usually under the name "Malapert Mountain" or "Malapert Peak") as an ideal base for future lunar observers. Some of the proponents have incorrectly stated that it is bathed in continuous sunlight. - JimMosher JimMosher


Nomenclature

  • Named for Charles Malapert (1581-1630), a Belgian astronomer, mathematician, and philosopher. Malapert was known as a staunch opponent of the Copernicans, and used his own astronomical observations to attack them. He published one of the earliest images of the Last Quarter Moon, following Galileo.
  • Use of this name on the Moon was introduced by [/Riccioli Riccioli] although the crater he intended to use the name for is highly uncertain. [/Whitaker Whitaker] believes it may have been the modern Simpelius B, which is probably as good a guess as any.
  • [/Neison%2C%201876 Neison, 1876], which greatly influenced the original [/IAU%20nomenclature IAU nomenclature], seems to follow [/Beer%20and%20M%C3%A4dler Beer and Mädler] in placing Malapert to the west of the Moon's prime meridian, directly under the peak Neison designated [/Montes%20Leibnitz#Neison Leibnitz Alpha] -- which can be identified with [/Whitaker%2C%201954 Whitaker, 1954]'s M5/M4. This does not agree with the position of the modern Malapert.
  • The name Malapert Alpha in the original [/IAU%20nomenclature IAU nomenclature] of [/Blagg%20and%20M%C3%BCller Blagg and Müller] (1935) was discontinued, along with most other Greek-lettered peaks, in [/IAU%20Transactions%20XVB 1973]. Since [/Neison%2C%201876 Neison, 1876] draws and describes it as being well to the west of Malapert (towards [/Cabeus Cabeus]), it seems unlikely to have been the same as [/Whitaker%2C%201954 Whitaker, 1954]'s Malapert Alpha.
  • [/Whitaker Whitaker] (p.25) dismisses Malapert's map as having "almost no merit", though it seems not much different from the engravings of Galileo, which Whitaker much admires. Malapert's engraving has the advantage of being dated, so that it can be compared to what would actually have been observed. It can be easily verified that the phase depicted agrees very well with what might have been seen in the pre-dawn hours of November 29, 1619, the stated date. The detailed features are less clear, but it appears to show [/Plato Plato], as expected, on the terminator to the north, with [/Eratosthenes Eratosthenes] and [/Copernicus Copernicus] below it. To the left of those Malapert appears to be indicating (somewhat out of place) the bright areas around [/Kepler Kepler] and [/Aristarchus Aristarchus]. In the south, [/Clavius Clavius] would have been on the terminator, and two craters, possibly [/Bullialdus Bullialdus] and [/Campanus Campanus], seem to have caught Malapert's eye and are shown to the left of his representation of the pockmarked lunar southern highlands. - JimMosher JimMosher
