The European cometary mission Rosetta derived its name from the famous stone, which is on display in the British Museum in London. The stone has been a fundamental landmark in deciphering the ancient Egyptian hieroglyphic scripture, as it was the Philae obelisk, which gave the name to the landing module of Rosetta. See Barbieri, 2017 and references therein for more details on the stone. As the stone was decisive for deciphering the hieroglyphic scripture, so the mission represents a fundamental landmark for cometary science.
