Nuclear submarines from Britain and France collided deep in the Atlantic Ocean in early February, authorities said in the first acknowledgment of a highly unusual accident that one expert called the gravest in nearly a decade. Officials said Feb. 16 that the low-speed crash did not damage the vessels' nuclear reactors or missiles or cause radiation to leak.

One day later, it was announced that two large communications satellites collided Feb. 10 in the first-ever crash of two intact spacecraft in orbit, shooting out a pair of massive debris clouds and posing a slight risk to the International Space Station. The collision involved a U.S. commercial satellite, launched in 1997, and a Russian satellite, launched in 1993. (AP)
