In a collaborative effort, LROC and ShadowCam teams release a composite image of the Shackleton Crater, offering unparalleled knowledge concerning the lunar South Pole and its hypothesized ice reserves, thus facilitating forthcoming missions to the Moon.

The recently revealed composite of the Shackleton Crater illustrates the potent collaboration between two lunar orbital cameras, which together disclose an unparalleled level of detail in the South Pole region of the Moon.

This composite image was crafted using pictures obtained by the Lunar Reconnaissance Orbiter Camera (LROC), operational since 2009, and from ShadowCam, a NASA instrument aboard a spacecraft from the Korea Aerospace Research Institute (KARI), named Danuri, which was launched in August 2022. ShadowCam was engineered by Malin Space Science Systems in partnership with Arizona State University.

Distinctive Functions of LROC and ShadowCam

While the LROC has the capability to acquire intricate images of the Moon’s surface, it has a restricted aptitude to capture images of areas in perpetual shadow that never receive direct sunlight. In contrast, ShadowCam has a light sensitivity that is 200 times greater than that of LROC, enabling it to operate effectively in extremely dim lighting conditions and reveal landscape features otherwise imperceptible to LROC. ShadowCam depends on sunlight reflected from lunar geological structures or Earth to capture images in shaded areas.

Conversely, ShadowCam’s elevated sensitivity to light renders it ineffectual at capturing images of areas directly exposed to sunlight, yielding overexposed outcomes. Utilizing each camera’s specialized attributes for different lighting environments near the lunar poles, analysts can amalgamate imagery from both instruments to generate an all-encompassing visual representation of the lunar landscape, covering both the brightest and the darkest regions. In this composite, the permanently shadowed sections, like the internal floor and walls of the Shackleton Crater, are vividly depicted due to ShadowCam’s capabilities, while the sunlit areas, including the rim and flanks of the crater, have been documented by LROC.

Scientific and Mission-Based Ramifications

ShadowCam enables NASA to image the perpetually shadowed zones of the Moon in more intricate detail than ever before, providing scientists with an enhanced view of the unexplored lunar South Pole region. This area is considered scientifically significant and of high exploration value as it is postulated to house ice deposits or other frozen volatiles. Researchers hypothesize that these ice layers have been present on the Moon for millions or even billions of years. Analyzing these samples could deepen our comprehension of the Moon’s and the solar system’s evolutionary history. Furthermore, these ice deposits are constituted of hydrogen and oxygen, elements crucial for rocket fuel and life-support systems.

A comprehensive map of the lunar South Pole is invaluable for future surface exploration initiatives, including the VIPER (Volatiles Investigating Polar Exploration Rover) and Artemis missions. These missions aim to re-establish human presence on the lunar surface and sustain a long-term lunar base.

About LROC

The Lunar Reconnaissance Orbiter Camera (LROC) is a suite of cameras installed on NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft. Launched in 2009, its principal objective is to assist in identifying secure landing sites, pinpoint potential resources, scrutinize the lunar environment, and pioneer new technologies. The detailed images obtained by LROC have been instrumental in providing deep insights into the Moon’s geological features and have been invaluable for numerous scientific and exploration missions.

About ShadowCam

ShadowCam is an exceedingly light-sensitive camera instrument on board the KARI (Korea Aerospace Research Institute) spacecraft, Danuri. Created by Malin Space Science Systems and Arizona State University specifically for NASA, it is specially designed to capture images of the Moon’s eternally shadowed regions, areas that are never exposed to direct sunlight. ShadowCam’s exceptional low-light operational capabilities make it possible to leverage reflected sunlight from the Moon’s geological formations or Earth to photograph features and topographical details that are invisible to instruments like LROC. Launched in August 2022, it complements other lunar imaging systems by uncovering details in the darkest regions of the Moon.
