What the evidence shows
NASA StarChild explains that the far side receives as much sunlight as the near side. A hemisphere hidden from Earth is not permanently unlit.

Claim provenance
The first claimant and first publication are unknown here. NASA documents the popular phrase but is not presented as its original author.
NASA Goddard's StarChild Team explicitly discusses the phrase 'dark side of the Moon' in The Dark Side of the Moon. The retrieved page has no established publication date; it is a documented explanation, not proof of the phrase's historical origin. Read the documented discussion.
Evidence review
The reviewed claim is about a permanently dark hemisphere, not merely the hemisphere hidden from an Earth-based observer. NASA distinguishes these meanings explicitly: the unseen hemisphere is more accurately called the far side. Being out of our view does not mean being out of sunlight. [1]
NASA's explanation states that the side we do not see from Earth receives just as much sunlight as the side we see. That directly contradicts the unqualified permanent-darkness assertion. The relevant distinction is illumination by the Sun versus visibility from Earth; those are different observing geometries. [1]
The source explains that the dark side at a given time is the side pointed away from the Sun. This is a temporary illumination condition rather than a fixed hemisphere. The verdict therefore rejects the literal permanent-dark-side claim while retaining the ordinary use of far side for the hemisphere facing away from Earth. [1]

“The side of the Moon we do not see from Earth gets just as much sunlight on it as the side we do see.”
The excerpt was found verbatim in the live cached PageExtractionProvider output; NASA directly distinguishes the far side from permanent darkness.
Scope and limitations
This is an editorial reading of NASA's educational explanation, verified through the existing cached page-extraction provider on October 30, 2026, not a new lunar illumination study. It concerns hemispheres, not every local crater or permanently shadowed polar region. No first historical claimant or publication date for the NASA page was established.
