Due to a glitch in the editorial process, the manuscript by Riofrio “Calculation of lunar orbit anomaly” (Riofrio, L., Planetary Science 2012, 1:1) was accepted for publication before the reviewing process was complete.

Post-publication reviews revealed that the observed Earth-Moon distance increase by ~3.82 cm/yr derived using Lunar Laser Ranging (LLR) has already been dealt with in the literature without having to assume any new fundamental physics like a cosmological variation of the speed of light as hypothesized by Riofrio in the above-cited publication.

The following new article “The Past and Present Earth-Moon System: the Speed of Light Stays Steady as Tides Evolve” by James G Williams, Slava G Turyshev, and Dale H Boggs, Planetary Sciences 2014, 3:2, addresses the issue of Earth-Moon distance variations again in a greater detail and confirms that no changes in fundamental physics are necessary to explain the observations.
