摘要

It is human nature to try to understand our place in the cosmos. Changes in our perception of human significance have accompanied many revolutions in scientific thought, such as the theory of evolution and establishing the order of the planets in the Solar System. So it is perhaps unsurprising that as soon as we developed the ability to launch projectiles into space, one of the first things we did was to use them to look back at ourselves. The history and significance of the view of Earth from space is the subject of Robert Poole's Earthrise. Although its publication is titled and timed to mark the 40th anniversary of the first snapshots of Earth rising over the Moon's horizon on 24 December 1968, the book also traces the long journey that led to Apollo 17's iconic image, 'Blue Marble', captured on 7 December 1972. Of the many attempts before the space age to understand how Earth looks from afar, the Roman historian Seneca provides the most remarkable quote: "Is this that pinpoint which is divided by fire and sword among so many nations? How ridiculous are the boundaries set by mortals." The first human view of the curvature of Earth is attributed to the high-altitude balloon flight of Explorer II in 1935. Floating 22 kilometres above the ground, two intrepid aeronauts inside the balloons pressurized gondola snapped a photograph that later appeared in National Geographic, with a line drawn across the horizon to illustrate that the curvature had been seen.
