Space disasters remind us that, no matter how mind-blowingly cool manned spaceflight is, the risks are dramatic and often absolute. A car crash can have devastating consequences, but at least it leaves you on the ground. When something goes wrong in space, it’s just you, some metal, a whole lot of combustible fuel, and the dark, cold loneliness of space. A total of 21 people have lost their lives in the pursuit of spaceflight, and many more in training exercises and rocket launches gone awry. Still, others died because their fascination for spaceflight put them at the wrong place, at exactly the wrong time.
