$3.9-bn spacecraft crashes into Saturn, ends 20-year mission
NASA's Cassini spacecraft plunged into Saturn's atmosphere on Friday at a speed of over 120,000 kmph, ending a $3.9-billion mission. Launched in 1997, the spacecraft travelled over 7.8 billion kms with respect to the Sun, discovering six moons. Cassini's achievements include finding ice and landing a probe on Saturn's largest moon Titan, besides discovering water jets over another moon Enceladus.
