Cassini’s 20 year mission ends
It is said this was the most successful planetary mission ever (I say so far). WAPO also has a couple of videos on the topic.
NASA scientists just received their last message from the Cassini spacecraft, which plunged into Saturn early Friday morning. Those final bits of data signal the end of one of the most successful planetary science missions in history.
“The signal from the spacecraft is gone and within the next 45 seconds so will be the spacecraft,” program manager Earl Maize reported from mission control at NASA's Jet Propulsion Laboratory, just after 4:55 a.m. local time. “This has been an incredible mission, an incredible spacecraft, and you're all an incredible team.”One of the last pieces of data captured by Cassini was an infrared image of the place into which it took its final plunge. The image, taken 15 hours before the spacecraft's demise, reveals a spot on Saturn's dark side just north of the planet's equator where the spacecraft disintegrated shortly after losing contact with Earth.
Cassini was the first probe to orbit Saturn. Built and operated at JPL, it was launched in 1997 and inserted into orbit in 2004. The spacecraft revealed the structure of Saturn's rings and, by delivering the Huygens probe to the moon Titan, executed the first landing of a spacecraft in the outer solar system. It also exposed two moons — Titan, a land of methane lakes, and Enceladus, which has jets of water streaming from its southern pole — as prime targets in the search for life beyond Earth.
