摘要

Bedbugs have had it their own way for a long time, sucking our blood while we sleep and evading detection by dint of their nocturnal lifestyle and millimetre-scale bodies. Our first visit to a comet could mark the point where the tables began to turn. A portable bedbug detector that sniffs out the chemical signals they send to one another is just one of many unusual spin-offs from the Rosetta mission, which arrived at comet 67P . late last year (see page 35). It's not surprising that many space technologies soon make their way into less rarefied domains. "Space stands for low-weight, robust, temperature-resistant technology that has to work," says Frank Salzgeber, head of technology transfer for the European Space Agency, which launched Rosetta. "Failure is not an option." Rosetta is an extreme example, first because of its decade-long journey through frigid, radiation-fried space to reach its target 800 million kilometres from the sun, and second for the fiddly operation to get its Philae lander on to comet 67P's rough surface. "Just imagine you ordered your car 12 years ago and got it 10 years ago," says Salzgeber. "You don't refuel it, it never gets any maintenance and you really treat it like shit: you go to the desert, to Siberia and then on the last day you go to Monza, the motor-racing circuit. The car's papers say it will run at 250 kilometres per hour, so you test it. And it works." For a time, anyway - a rather bumpy landing put Philae to sleep after just two days (see "Come in, comet", page 37).
