I quite like Voyager continuing Apollo’s space program theme.

Another option in tribute to Apollo is “Delphi”.

Delphi is the site of the Temple of Apollo and was an ancient sacred precinct and the seat of Pythia, the major oracle who was consulted about important decisions throughout the ancient classical world. The ancient Greeks considered the centre of the world to be in Delphi.

As well as the links to Apollo, Delphi’s history is of a community sanctuary and a central source of wisdom.

The term Delphi is more unique than Voyager so it will be more searchable and should be easier to secure a domain name.

Here are a few interesting quotes from the Delphi Temple of Apollo wiki:

The Temple of Apollo, was a major part of the Panhellenic religious sanctuary located in Central Greece at Delphi. The temple and sanctuary at large were dedicated to one of the major Greek deities, Apollo.

Within the ancient Greek world, Delphi was considered the center of the universe, marked by the omphalos, or “navel”, of the Earth that was located in Apollo’s sacred temple. The Temple of Apollo at Delphi was perceived as an incredibly sacred site, considered a major center of ancient Greek religious practice and belief as well as a place intimately connected to the gods.

The exterior of the temple was also decorated with metopes, with five major depictions of gods and heroes being victorious over monsters, a mirroring of Apollo’s defeat of Python during the mythological founding of the Temple of Apollo at Delphi.

The priestesses of Apollo, known as the Pythia, served as the oracle for the Temple of Apollo at Delphi. Greeks and non-Greeks alike would go to the Temple of Apollo at Delphi from across the Mediterranean and beyond to consult the Pythia on a variety of different topics, ranging from the state level like the establishment of new colonies to the personal level like marriage, children, and health.
