"A gung-ho approach to speed would violate the considerations of space ecology promoted by Rubenstein in Astrotopia: The Dangerous Religion of the Corporate Space Race. Rubenstein, while expertly dismantling some overblown claims of companies such as SpaceX and Blue Origin, proposes a gentler mode of space exploration that refuses to rehearse the violent history of colonialism on earth. In a way her vision recalls Capt. Kirk and Mr. Spock's Prime Directive: to avoid interference with other life forms. The original Star Trek series began in 1966, only months after the death of Sergei Korolev. Perhaps it still has something to teach us."–Steven Poole "Wall Street Journal"
