The first Orbiting Carbon Observatory (OCO) was lost on the way to space because of fraudulent metal provided by a supplier. The OCO was rebuilt at OCO-2, which has since collected data on the spatial distribution of carbon dioxide on Earth. OCO-3 will be attached to the International Space Station, which will further fill in […]

Of course, the Columbia and Challenger accidents have reminded us we need to be ever vigilant. Despite more than two years of careful work to prevent foam shedding from the shuttle’s main tank, my STS-114 mission lost a large piece of foam on ascent, in a circumstance very similar to what happened to Columbia on […]

Then they led him out again, trying to get him near a mockup of a Mercury capsule, where the television networks had set up cameras and tremendous lights. The reporters and photographers surged forward again, yammering, yelling, exploding more camera lights, shoving, groaning, cursing—the usual yahoo sprawl, in short—and the animal came unglued again, ready […]

With the decline of archaic magic, the belief in single combat began to die out. The development of the modern, highly organized army and the concept of “total war” seemed to bury it forever. But then an extraordinary thing happened: the atomic bomb was invented, with the result that the concept of total war was […]

Fortunately, there was always some kindly soul up the chain to certify the papers “line of duty,” so that the widow could get a better break on the insurance. That was okay and only proper because somehow the system itself had long ago said Skol! and […]
