It encompasses discovery, instrumentation, adventure, settlement proposals and the longer question of which forms of intelligence can actually move through interstellar space. ## Conceptual relationships [[wiki/Space Technology|Space Technology]] · [[wiki/Human Spaceflight|Human Spaceflight]] · [[wiki/Robotic Spaceflight|Robotic Spaceflight]] ## Martin Rees research route [[research/Martin Rees on Machine Succession, Post-Human Intelligence, and the Cosmic Future|Martin Rees on Machine Succession, Post-Human Intelligence, and the Cosmic Future]] supplies a primary quotation dossier connecting this concept to Rees's work on cosmology, technological risk, machine intelligence, posthuman evolution and deep time. ## Article and collection routes - [[collections/Machine Succession|Machine Succession]] - [[articles/We Cannot Un-Strike the Match|We Cannot Un-Strike the Match]] - [[articles/The Last Migration Will Not Be Human|The Last Migration Will Not Be Human]] - [[articles/We Were Never Going to Make It|We Were Never Going to Make It]] ## Simple Reminders, Quotations, and Thoughts <!-- BEGIN MARTIN REES MASTER REMINDERS 2026-10-05 --> > “The first voyagers to the stars will not be human, and maybe not even organic.” > **— Martin Rees**, *Interstellar Travel and Post-Humans, Lifeboat Foundation, Essay* [[reminders/Space Survival/The First Voyagers to the Stars May Not Be Organic by Martin Rees|The First Voyagers to the Stars May Not Be Organic by Martin Rees]] > “Space adventure, not space tourism.” > **— Martin Rees**, *Martin Rees: Black Holes, Alien Life, Dark Matter, and the Big Bang, Lex Fridman Podcast \#305 transcript, 2022* [[reminders/Exploration/Space Should Be Adventure Not Tourism by Martin Rees|Space Should Be Adventure Not Tourism by Martin Rees]] > “The entire solar system will be explored by flotillas of robotic craft.” > **— Martin Rees**, *No need for manned spaceflight, says Astronomer Royal Martin Rees, The Guardian, 2010* [[reminders/Robotics/Robotic Flotillas Will Explore the Solar System by Martin Rees|Robotic Flotillas Will Explore the Solar System by Martin Rees]] > “As a scientist and practical man, I am sceptical about manned space flight, but, as a human being, I am strongly in favour.” > **— Martin Rees**, *Oral evidence: Space policy, UK House of Commons Science and Technology Committee, 2007* [[reminders/Exploration/Human Spaceflight Can Be Impractical and Magnificent by Martin Rees|Human Spaceflight Can Be Impractical and Magnificent by Martin Rees]] <!-- END MARTIN REES MASTER REMINDERS 2026-10-05 -->
