In 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO.) Its ongoing mission is to map the lunar surface in detail, locating potential landing sites, resources, and interesting features like lava tubes. The mission is an ongoing success, another showcase of NASA’s skill. It’s mapped about 98.2% of the lunar surface, excluding the deeply shadowed regions in the polar areas.

But recently, the LRO team’s skill was on display for another reason: it captured images of another satellite speeding over the lunar surface.

The Darkest Parts of the Moon are Revealed with NASA’s New Camera

While the surface of the Moon has been mapped in incredible detail over the last several decades, one region has eluded orbital cameras due to the lack of sunlight, which are aptly called the permanently shadowed regions (PSRs) of the Moon. However, two cameras operating on two different lunar orbiters have recently worked in tandem to produce a stunning mosaic image of the lunar south pole’s Shackleton Crater, a portion of which resides directly on the lunar south pole and whose depths have been shrouded in complete darkness for possibly the last few billion years. As a result, scientists hypothesize that water ice could have accumulated within its dark depths that future astronauts could use for fuel and life support.

New Spacecraft Can See Into the Permanently Shadowed Craters on the Moon

Shackleton Crater at the lunar south pole is one of the locations on NASA’s shortlist for human exploration with the future Artemis missions. But because craters at the lunar poles — like Shackleton — at have areas that are perpetually in shadow, known as permanently shadowed regions (PSRs), we don’t know for sure what lies inside the interior. However, a new spacecraft with a specialized instrument is about to change all that.
