A new book "Visions, Ventures, Escape Velocities: A Collection of Space Futures" was published today, featuring a collection of short stories and essays imaging our future in space. Sara Walker contributed an essay commentary titled "The New Science of Astrobiology" on Singh's short story "Shikasta". Singh's story is a thought-provoking take on the possible futures for astrobiology and the discovery of alien life (featuring a cameo of work from the Walker group!). Read Singh's story and Sara's commentary, along with other excellent contributions on Mars exploration, low-Earth orbit and exoplanets here.
