SS Statendam was an ocean liner of the Holland America Line built in 1957.

[2][3] The ship was the venue for a conference on space exploration held to coincide with the December, 1972 launch of Apollo 17.

Panelists included science fiction authors, scientists, and others ranging from Isaac Asimov to Norman Mailer to Katherine Anne Porter.

The cruise had only 100 paying fares, only 40 of whom paid the additional conference fee, and Holland-America Line lost an estimated $250,000 on the venture.

A key organizer of the expedition was Richard C. Hoagland, while the symposium moderator was Hugh Downs; both would later play roles in the "pro-space movement", which space historian Michael Michaud believes found a nascent constituency at the conference.
