NASA to live stream spacecraft crashing into Saturn
NASA is broadcasting live footage of the final stages of Cassini spacecraft's dive into Saturn's atmosphere. Dubbed the "Grand Finale", the event marks an end to the 20-year, $3.9-billion mission of the first-ever spacecraft that went between Saturn's planet-ring gap. Cassini helped study the planet, its rings of ice and dust, and discovered water on its moons Titan and Enceladus.
