Geschafft: Spacecraft Dives Between Saturn and Its Rings

NASA's Cassini spacecraft is back in contact with Earth after its successful first-ever dive through the narrow gap between the planet Saturn and its rings on April 26, 2017. The spacecraft is in the process of beaming back science and engineering data collected during its passage, via NASA's Deep Space Network Goldstone Complex in California's Mojave Desert. The DSN acquired Cassini's signal at 11:56 p.m. PDT on April 26, 2017 (2:56 a.m. EDT on April 27) and data began flowing at 12:01 a.m. PDT (3:01 a.m. EDT) on April 27.

Planmäßig wurde wieder Kontakt mit der Sonde aufgenommen. 22 Stunden nach der ersten Passage zwischen Ring und Planet, sind nun die ersten Bilder reingekommen:

Heute morgen hat Cassini zum dritten Mal die Ringebene im Zwischenraum zwischen der oberen Atmosphäre von Saturn und dem inneren D-Ring durchquert:

Cassini Flies Toward a Fiery Death on Saturn

The Cassini spacecraft that has orbited Saturn for the last 13 years ..., on Friday morning, the whole world will hear it die.

At the Jet Propulsion Laboratory in California, the scientists of the Cassini mission will figuratively ride their creation down into oblivion in the clouds of Saturn. They will be collecting data on the makeup of the planet’s butterscotch clouds until the last bitter moment, when the spacecraft succumbs to the heat and pressure of atmospheric entry and becomes a meteor.

Cassini makes its 'goodbye kiss' flyby of Titan

NASA's Cassini spacecraft is headed toward its Sept. 15 plunge into Saturn, following a final, distant flyby of the planet's giant moon Titan.

The spacecraft made its closest approach to Titan today at 12:04 p.m. PDT (3:04 p.m. EDT), at an altitude of 119,049 kilometers above the moon's surface. The spacecraft is scheduled to make contact with Earth on Sept. 12 at about 6:19 p.m. PDT (9:19 p.m. EDT). Images and other science data taken during the encounter are expected to begin streaming to Earth soon after. Navigators will analyze the spacecraft's trajectory following this downlink to confirm that Cassini is precisely on course to dive into Saturn at the planned time, location and altitude.

Re: Cassini's Grand Finale

Diesen Freitag, am 15. September 2017, um 13:55 MESZ soll das auf der Erde eintreffende Radiosignal von Cassini verschwinden, was dann das Eintauchen der Sonde in die tieferen Schichten der Atmosphäre von Saturn markiert.

Latest Status

End of Mission Timeline

Because Saturn is so far from Earth, Cassini will have been gone for about 83 minutes by the time its final signal reaches the Deep Space Network's Canberra station in Australia on Sept. 15, 2017.

Um 13:55 unserer Zeit verschwand das Cassini Signal, wie vorausgesagt.

Hier sind ein paar Bilder mit dem letzten Lebenszeichen von Cassini und der emotionalen Stimmung im Kontrollzentrum.

Re: Cassini's Grand Finale

Habe mir die letzten Minuten von Cassini im Livestream angesehen... Traurig uns schön zugleich... Wenn ich mir vorstelle, ich hätte jetzt 20 Jahre oder länger an dem Projekt gearbeitet... Bin gespannt auf die letzten Bilder!

Re: Cassini's Grand Finale

Nicht das allerletzte Bild, aber ein schönes Abschiedsportrait beim finalen Anflug am 13. September:

Cassini's farewell to Saturn

The Cassini spacecraft took one last, lingering look at Saturn and its splendid rings during the final leg of its journey and snapped a series of images that has been assembled into a new mosaic.

Cassini's wide-angle camera acquired 42 red, green and blue images, covering the planet and its main rings from one end to the other, on Sept. 13, 2017. Imaging scientists stitched these frames together to make a natural color view.
