The answer to the above question seems to be variable (but essentially unchanged). I have received the following:
Quote:René Zandbergen, a well-known researcher of the Voynich manuscript, has recently shown interest in the theory that the manuscript might have Martian origins. This shift is intriguing, considering his extensive background in both space science and cryptology.
Zandbergen's acceptance of the Martian theory seems to stem from a combination of his expertise in space dynamics and his long-term study of the Voynich manuscript. His work at the European Space Agency involves high-precision orbit determination, which has likely influenced his perspective on the plausibility of extraterrestrial connections. His interest in the manuscript’s origins aligns with the recent surge in theories proposing that life or artifacts might have been transferred between Earth and Mars via panspermia or other means (CryptoHistory) (livescience.com).
