Astronomy: Rings, Titan and Enceladus

Hi My Friends: AL VUELO DE UN QUINDE EL BLOG., Saturn’s icy moon Enceladus hangs below the gas giant’s rings while Titan lurks in the background, in this new image taken by the Cassini spacecraft. Saturn’s icy moon Enceladus hangs below the gas giant’s rings while Titan lurks in the background, in this new image taken by the Cassini spacecraft.

Faint detail of the tiger stripe markings can be seen on Enceladus’ surface, which is framed against Titan, Saturn’s largest moon. With jets of water ice and vapour streaming from Enceladus’ south pole, and liquid hydrocarbon lakes pooling beneath Titan’s thick atmosphere, these are two of Saturn’s most enigmatic moons.

The northern, sun-lit side of Saturn’s rings are seen from just above the ring plane in this image, which was taken in visible green light by Cassini’s narrow-angle camera on 12 March while it was approximately one million kilometres from Enceladus. The image scale is six kilometres per pixel on Enceladus.

Cassini Mission Receives Air and Space Museum Award.

PASADENA, Calif. -- The Smithsonian's National Air and Space Museum has bestowed its highest group honor, the Trophy for Current Achievement, on NASA's Cassini mission to Saturn. The annual award recognizes outstanding achievements in the fields of aerospace science and technology.
The trophy was presented Wednesday, March 21, during an evening ceremony at the museum in Washington. Established in 1985, the award has been presented to seven NASA planetary mission teams.
"This joint mission has produced an unprecedented science return," said William Knopf, Cassini program executive at NASA Headquarters in Washington. "Missions like Cassini pave the way for future robotic and human exploration throughout our solar system and beyond."
Launched in 1997, the Cassini spacecraft entered Saturn's orbit in June 2004 with the European Space Agency's (ESA) Huygens probe bolted to its side. In December 2004, the spacecraft successfully released Huygens, which entered the atmosphere of Saturn's largest moon, Titan. Cassini completed its prime mission in 2008 and has been extended twice. It is now in its so-called solstice mission, which will enable scientists to observe seasonal changes in Saturn and its moons during the planet's northern summer solstice. The mission will last through September 2017.
"We look forward to sailing around the Saturn system for several more years to see how our views of the planet and its magnificent moons change as we get into northern summer solstice," said Robert Mitchell, the Cassini program manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif., who accepted the award on behalf of the team.
The Cassini spacecraft carries 12 science instruments and investigations, with an additional six aboard Huygens. Cassini mission highlights to date include the discovery of four new moons and two new rings around Saturn. Cassini observed spraying water vapor and icy particle jets from the moon Enceladus. In Saturn's northern hemisphere, the spacecraft watched the evolution of a monster storm, a sign of seasonal change from northern winter into northern spring.
Cassini and Huygens has also revealed new characteristics about Titan, the only body in the solar system other than Earth with stable liquid on its surface.
The Cassini-Huygens mission is a cooperative project of NASA, ESA and the Italian Space Agency. JPL manages the mission for NASA's Science Mission Directorate in Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. JPL is managed for NASA by the California Institute of Technology in Pasadena.

Astronomy: Rhea Before Titan

Hi My Friends: AL VUELO DE UN QUINDE EL BLOG., Craters appear well defined on icy Rhea in front of the hazy orb of the much larger moon Titan in this Cassini spacecraft view of these two Saturn moons. Craters appear well defined on icy Rhea in front of the hazy orb of the much larger moon Titan in this Cassini spacecraft view of these two Saturn moons.

Lit terrain seen here is on the leading hemispheres of Rhea and Titan. North on the moons is up and rotated 13 degrees to the left. The limb, or edge of the visible disk, of Rhea is slightly overexposed in this view.

The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Dec. 10, 2011. The view was acquired at a distance of approximately 1.2 million miles (2 million kilometers) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 109 degrees. The view was acquired at a distance of approximately 810,000 miles (1.3 million kilometers) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 109 degrees. Image scale is 8 miles (12 kilometers) per pixel on Titan and 5 miles (8 kilometers) per pixel on Rhea.

Astronomy: Welcome Disruption

Hi My Friends: AL VUELO DE UN QUINDE EL BLOG., The line of Saturn's rings disrupts the Cassini spacecraft's view of the moons Tethys and Titan. Welcome Disruption
The line of Saturn's rings disrupts the Cassini spacecraft's view of the moons Tethys and Titan.

Larger Titan (3,200 miles, or 5,150 kilometers across) is on the left. Tethys (660 miles, or 1,062 kilometers across) is near the center of the image. This view looks toward the Saturn-facing sides of Tethys and Titan. The angle also shows the northern, sunlit side of the rings from less than one degree above the ring plane. The image was taken in visible red light with the Cassini spacecraft narrow-angle camera on Dec. 7, 2011. The view was acquired at a distance of approximately 1.4 million miles (2.2 million kilometers) from Tethys and 1.9 million miles (3.1 million kilometers) from Titan. Image scale is 8 miles (13 kilometers) per pixel on Tethys and 12 miles (19 kilometers) on Titan.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two on-board cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
