摘要

One message of this special issue is how, well, normal space exploration has become since Neil Armstrong and Buzz Aldrin landed on the moon almost exactly 50 years ago. The number of satellites launched each year is shooting up as rockets get cheaper and satellites get smaller (see the charts on pages 14 and 30). Though only a few hundred people have been to space, billions depend on it: much of modern life would grind to a halt without GPS, satellite communications, and imagery from space. Apollo's most important legacy, we argue (page 8), wasn't that it put a person on the moon, but that it taught people to manage the kinds of gigantic engineering projects that have made those once miraculous technologies thoroughly mundane. Even a return visit to the moon, which could happen in the next few years, would now be a lot easier (page 48).If once the biggest problems in space were how to get stuff up there, make it work, and bring it back, today's problems arise because humanity has gotten all too good at doing so. There could soon be enough imaging satellites to subject everyone on Earth to constant real-time surveillance (page 32); there are fights over an increasingly crowded radio frequency spectrum (page 40); and it can only be a matter of time before someone acquires both the means and the motive to attack someone else's satellite, potentially launching the first full-on space war (page 36).
