Cassini's final image before eternal slumber. β€’ This natural color view, created using images taken with red, green and blue spectral filters of Cassini's Solid-State Imaging system, is the last image taken by the spacecraft. It looks toward the planet's night side, lit by reflected light from the rings, and shows the location at which the spacecraft would enter the planet's atmosphere hours later. β€’ NASA / JPL-Caltech / SSI β€’ #space #cassini #nasa #planets #saturn #theplanetarysociety

The #Cassini Signature Disk, with over 600,000 signatures from 81 countries, is now a part of Saturn. Volunteers from the Planetary Society sorted, counted, and scanned all of the signatures for inclusion on the DVD that traveled aboard the spacecraft! β€’ Want to be a part of epic moments like this for future missions?

Cassini is no more. At 10:31 UTC according to its own clock, its thrusters could no longer hold its radio antenna pointed at Earth, and it turned away. A minute later, it vaporized in Saturn’s atmosphere. Its atoms are part of Saturn now – the lighter ones high in the atmosphere, the heavier ones (particularly the iridium-clad plutonium dioxide pellets that were, yesterday, in the center of its nuclear power source) likely descended much deeper before melting. With that, there is one less robotic explorer in our sky. So long, Cassini, and thanks for all the science!

Do not go gentle into that good night, dear friend. β€’ Today is the Cassini spacecraft's last day of operation in this solar system. One of the greatest robotic explorers ever has taken its last images before its crash course into Saturn. Expected loss of signal tomorrow morning at 07:54 EDT. So long, and thanks for all the science! β€’ Image: NASA / JPL-Caltech / SSI / Doug Ellison β€’ #grandfinale #cassini #saturn #nasa #esa #jpl #space #goodbye

Farewell, Cassini! The Cassini mission is the longest-lived orbiter flying beyond Earth. We are now just days away from its end. Scroll through our gallery and enjoy just a few of the many visual gifts this spacecraft has given us. β€’ #cassini #saturn #nasa #space #cassiniinspires #cassinisaturn

#Eclipse2017 from space, just look at that massive umbra! β€’ These images are from the Earth Polychromatic Camera on the DSCOVR spacecraft. β€’ Where are the stars? We get this question a lot! It’s all about the camera settings. Shorter exposure imagery of the Earth β€” the majority of daytime images β€” typically do not record stars as they are too dim compared to the brightness of the planet. β€’ Where in the world were you to experience the eclipse? β€’ #eclipse #moon #sun #earth #solareclipse2017 #solareclipse #space #nasa

What a totally awesome total solar eclipse! We had a blast experiencing our place in space with the @nationalparkservice, hope everyone who looked up felt the joy of space! #eclipse2017

Look closely and you'll see the ultimate #Eclipse2017 group photo.... the Moon, sunspots AND a space station in front of the sun. β€’ The International Space Station, with a crew of six onboard, is seen in silhouette as it transits the Sun at roughly five miles per second during a partial solar eclipse, Monday, Aug. 21, 2017 near Banner, Wyoming. Onboard as part of Expedition 52 are: NASA astronauts Peggy Whitson, Jack Fischer, and Randy Bresnik; Russian cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy; and ESA (European Space Agency) astronaut Paolo Nespoli. A total solar eclipse swept across a narrow portion of the contiguous United States from Lincoln Beach, Oregon to Charleston, South Carolina. A partial solar eclipse was visible across the entire North American continent along with parts of South America, Africa, and Europe.
