The Crew of the Leonov is given the message
A 1981 Nature article provides an explanation for the appearance of an object on this body which is later confirmed when an Afrikaaner refugee sends the message "LUCY IS HERE" to his uncle. A realization made in this location allows the construction of four towers which connect to an orbital ring. Due to tidal locking, residents of this location can only experience night on the "farside" which leads to their mythologizing their "cold sun". Mt. Zeus on this body is revealed to be an enormous chunk of diamond ejected during the formation of Lucifer from the core of a planet. The Crew of the Leonov is given the message ALL THESE WORLDS ARE YOURS except this particular world which they are told to attempt no landings on. For 10 points, name this Jovian moon central to the plots of 2010: Odyssey Two, and 2061: Odyssey Three due to its potential for hosting life.
