NASA - National Aeronautics and Space AdministrationPasadena, CA – A new movie sequence of images from NASA’s Cassini spacecraft shows the view as the spacecraft swooped over Saturn during the first of its Grand Finale dives between the planet and its rings on April 26th.

The movie comprises one hour of observations as the spacecraft moved southward over Saturn. It begins with a view of the swirling vortex at the planet’s north pole, then heads past the outer boundary of the hexagon-shaped jet stream and beyond.

NASA - National Aeronautics and Space AdministrationPasadena, CA – As NASA’s Cassini spacecraft prepares to shoot the narrow gap between Saturn and its rings for the second time in its Grand Finale, Cassini engineers are delighted, while ring scientists are puzzled, that the region appears to be relatively dust-free. This assessment is based on data Cassini collected during its first dive through the region on April 26th.

With this information in hand, the Cassini team will now move forward with its preferred plan of science observations.

NASA’s Cassini spacecraft completes voyage between Saturn and it’s Rings

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – 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 26th, 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 11:56pm PDT on April 26th, 2017 (1:56am CDT on April 27th) and data began flowing at 12:01am PDT (2:01am CDT) on April 27th.

NASA’s Cassini Spacecraft set to dive between Saturn and it’s Rings

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft is set to make its first dive through the narrow gap between Saturn and its rings on April 26th, 2017.

Because that gap is a region no spacecraft has ever explored, Cassini will use its dish-shaped high-gain antenna (13 feet or 4 meters across) as a protective shield while passing through the ring plane. No particles larger than smoke particles are expected, but the precautionary measure is being taken on the first dive.

NASA’s Cassini spacecraft finishes last close orbit of Saturn’s moon Titan

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – 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 21st at 11:08pm PDT (1:08am CDT on April 22nd), passing at an altitude of about 608 miles (979 kilometers) above the moon’s surface.

Cassini transmitted its images and other data to Earth following the encounter.

NASA’s Cassini spacecraft begins last close flyby of Saturn’s moon Titan

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft will make its final close flyby of Saturn’s haze-enshrouded moon Titan this weekend.

The flyby marks the mission’s final opportunity for up-close observations of the lakes and seas of liquid hydrocarbons that spread across the moon’s northern polar region, and the last chance to use its powerful radar to pierce the haze and make detailed images of the surface.

Closest approach to Titan is planned for 11:08pm PDT on April 21st (2:08am EDT April 22nd). During the encounter, Cassini will pass as close as 608 miles (979 kilometers) above Titan’s surface at a speed of about 13,000 mph (21,000 kph).

Cassini will make its final close flyby of Saturn's moon Titan on April 21st (PDT), using its radar to reveal the moon's surface lakes and seas one last time. (NASA/JPL-Caltech)

NASA’s Cassini spacecraft takes photos of Saturn’s moon Atlas

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – These raw, unprocessed images of Saturn’s moon, Atlas, were taken on April 12th, 2017, by NASA’s Cassini spacecraft. The flyby had a close-approach distance of about 7,000 miles (11,000 kilometers).

These images are the closest ever taken of Atlas and will help to characterize its shape and geology. Atlas (19 miles, or 30 kilometers across) orbits Saturn just outside the A ring — the outermost of the planet’s bright, main rings.

NASA’s Cassini mission and Hubble Space Telescope provides new details about moons Enceladus and Europa

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other “ocean worlds” in our solar system and beyond. The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescope.

In the papers, Cassini scientists announce that a form of chemical energy that life can feed on appears to exist on Saturn’s moon Enceladus, and Hubble researchers report additional evidence of plumes erupting from Jupiter’s moon Europa.

This artist's rendering shows Cassini diving through the Enceladus plume in 2015. New ocean world discoveries from Cassini and Hubble will help inform future exploration and the broader search for life beyond Earth. (NASA/JPL-Caltech)

NASA’s Cassini spacecraft to begin final orbits around Saturn

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft, in orbit around Saturn since 2004, is about to begin the final chapter of its remarkable story. On Wednesday, April 26th, the spacecraft will make the first in a series of dives through the 1,500-mile-wide (2,400-kilometer) gap between Saturn and its rings as part of the mission’s grand finale.

“No spacecraft has ever gone through the unique region that we’ll attempt to boldly cross 22 times,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “What we learn from Cassini’s daring final orbits will further our understanding of how giant planets, and planetary systems everywhere, form and evolve. This is truly discovery in action to the very end.”

NASA study shows hydrocarbon seas on Saturn’s moon Titan could bubble with Nitrogen

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A recent NASA-funded study has shown how the hydrocarbon lakes and seas of Saturn’s moon Titan might occasionally erupt with dramatic patches of bubbles.

For the study, researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, simulated the frigid surface conditions on Titan, finding that significant amounts of nitrogen can be dissolved in the extremely cold liquid methane that rains from the skies and collects in rivers, lakes and seas.

Cassini captured this mosaic of images showing the northern lakes and seas of Saturn's moon Titan on Feb. 17, 2017. The mission's final close Titan flyby is planned for April 22. (NASA/JPL-Caltech/Space Science Institute)
