SUMMARY: Some 800 million miles away, NASA's Cassini spacecraft has orbited Saturn and captured images of its rings and icy moons. After nearly 5 billion miles traveled and 20 years of sending revealing data from the gas giant, Cassini is winding down its way toward a suicide plunge into the planet. Science correspondent Miles O'Brien reports on how NASA is choreographing the spacecraft's final dive.
WILLIAM BRANGHAM (NewsHour): Some of the numbers involved in the Cassini mission are truly mind-blowing.
More than 290 orbits of Saturn, nearly five billion miles traveled, 450,000-plus images taken. There have been nearly 4,000 papers published about the work. And it included the participation of 27 nations.
