Last Cassini Flyby of Titan Completed
Last Cassini Flyby of Titan Completed

Cassini Completes Final and Fateful Titan Flyby “NASA’s Cassini spacecraft has had its last close brush with Saturn’s hazy moon Titan and is now beginning its final set of 22 orbits around the ringed planet.” “The spacecraft made its 127th and final close approach to Titan on April 21 at 11:08 p.m. PDT (2:08 a.m. EDT on April 22), passing at an altitude of about 608 miles (979 kilometers) above […]

Hydrothermal Activity in The Seas of Enceladus
Hydrothermal Activity in The Seas of Enceladus

Hydrothermal Activity in The Seas of Enceladus: Implications For Habitable Zones, Astrobiology.com First posted on 11 April 2017 at 7:16 pm EDT. “On Thursday NASA will announce evidence that hydrothermal activity on the floor of an ice-covered ocean on Saturn’s moon Enceladus is most likely creating methane from carbon dioxide. The process is indicative of possible habitable zones within the ocean of Enceladus. But before we go any further, “habitable” […]

Using Art to Explain Space Science

Keith’s note: The artists at JPL who created the farewell video for Cassini must have seen “Wanderers” – and “Interstellar”. If so, it shows. That’s OK. This JPL creation sets a new standard for displaying what NASA missions have done and the true scale of the vistas these probes would see if we humans were not constantly telling them what to look at. The more of these videos NASA makes, […]

A New View of Prometheus
A New View of Prometheus

Close Up View of Prometheus “NASA’s Cassini spacecraft spied details on the pockmarked surface of Saturn’s moon Prometheus (86 kilometers, or 53 miles across) during a moderately close flyby on Dec. 6, 2015. This view looks towards the anti-Saturn side of Prometheus. North on Prometheus is up. The image was taken in visible light with the Cassini spacecraft narrow-angle camera.”

During The Stupid Shutdown The Universe Continued to Be Awesome

Stunning View From High Above Saturn “This portrait looking down on Saturn and its rings was created from images obtained by NASA’s Cassini spacecraft on Oct. 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected for shifts in the spacecraft perspective and still has some camera artifacts.”

Important Titan Flyby Wednesday

Significant Titan Flyby Happening on July 10th, NASA “For the Radar instrument, one of the most significant Titan fly-bys of the extended Solstice mission occurs July 10. Measurements from this flyby, combined with data from the previous flyby, will allow scientists to produce stereo images of lakes. Inbound, the imaging science subsystem (ISS) will acquire a mosaic of high northern latitudes on Titan’s leading hemisphere, approaching northern summer. This area […]

Turning Imagery into Art

Sander van den Berg: “The footage in this video is derived from image sequences from NASA’s Cassini and Voyager missions. I downloaden a large amount of raw images to create the video.”

Cassini Experiences Communications Problems

NASA Cassini Significant Events 12/21/11 – 1/3/12 “Friday, Dec. 23 (DOY 357) – No signal was detected from the spacecraft today at the beginning of track at Deep Space Station (DSS) DSS-43, the Canberra 70 meter station. Additional tracking was obtained at Canberra’s DSS-45 and Goldstone’s DSS-14 to no avail. The 2-way coherent signal was acquired at the one round trip light-time point into the track as usual, indicating it […]

More Spectacular Images From Cassini

Photo: Titan and Dione As Seen by Cassini “Saturn’s third-largest moon Dione can be seen through the haze of its largest moon, Titan, in this view of the two posing before the planet and its rings from NASA’s Cassini spacecraft. This view looks toward the anti-Saturn side of Titan (3200 miles, 5150 kilometers across) and Dione (698 miles, 1123 kilometers across). North is up on the moons. This view looks […]

Titan, a Neighbor – and Saturn

Photo: Titan And Another Moon Set Against Saturn’s Rings “This image was taken on May 21, 2011 and received on Earth May 22, 2011. The camera was pointing toward Titan at approximately 2,313,374 kilometers away, and the image was taken using the CL1 and GRN filters. This image has not been validated or calibrated.”
