Three Times the Fun

Three of Saturn's moons -- Tethys, Enceladus and Mimas -- are captured in this group photo from NASA's Cassini spacecraft.

Tethys (660 miles or 1,062 kilometers across) appears above the rings, while Enceladus (313 miles or 504 kilometers across) sits just below center. Mimas (246 miles or 396 kilometers across) hangs below and to the left of Enceladus.

This view looks toward the sunlit side of the rings from about 0.4 degrees above the ring plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 3, 2015.

The view was acquired at a distance of approximately 837,000 miles (1.35 million kilometers) from Enceladus, with an image scale of 5 miles (8 kilometers) per pixel. Tethys was approximately 1.2 million miles (1.9 million kilometers) away with an image scale of 7 miles (11 kilometers) per pixel.  Mimas was approximately 1.1 million miles (1.7 million kilometers) away with an image scale of 6 miles (10 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (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. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

Ices and Shadows

Saturn's moon Tethys appears to float between two sets of rings in this view from NASA's Cassini spacecraft, but it's just a trick of geometry. The rings, which are seen nearly edge-on, are the dark bands above Tethys, while their curving shadows paint the planet at the bottom of the image.

Tethys (660 miles or 1,062 kilometers across) has a surface composed mostly of water ice, much like Saturn's rings. Water ice dominates the icy surfaces in the the far reaches of our solar system, but ammonia and methane ices also can be found.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on Nov. 23, 2015. North on Tethys is up. The view was obtained at a distance of approximately 40,000 miles (65,000 kilometers) from Tethys. Image scale is 2.4 miles (4 kilometers) per pixel.

el dispensador dice:
los anillos de los dedos de la mano izquierda,
no suplen a los anillos del alma...
los compromisos pronunciados mediante palabras,
no emulan ni superan,
los sentimientos que anidan en el alma...
si en tus hechos no hay paz,
tus rutinas amanecerán en un drama,
para alcanzar el ocaso,
justificando el desprecio que emana de ojos... que enseñan no saber de las calmas.
febrero 22, 2016.-

ningún altar, por más que de fino mármol sea... salva.

ningún sacerdote, por más santo que se muestre... bendice lo que el alma usa de trampa.

no hay sagradas escrituras... que revelen lo que en el paraíso es trama.

no hay textos sagrados... que den por concedido, aquello que ha servido para que alguien se erija como propietario.

sólo los hechos... conducen el paraíso añorado.
