The Week in SpaceApril 26 - May 2, 2010
Tectonic Feast NASA’s Cassini captured this mosaic of Enceladus as the spacecraft sped away from this geologically active moon of Saturn in October 2008. This southern region of the moon’s Saturn-facing hemisphere displays very few impact craters, but is replete with fractures, folds, and ridges—all hallmarks of remarkable tectonic activity for a world only 300 miles in diameter. Portions of the tiger stripe fractures, or sulci, are visible along the terminator at lower right, surrounded by a circumpolar belt of mountains. The icy moon’s famed jets emanate from at least eight distinct source regions, which lie on or near the tiger stripes. In this view, the most prominent feature is Labtayt Sulci, the approximately half-mile-deep northward-trending chasm located just above the center of the mosaic.

Customer Comment
I have enjoyed The Year In Space desk calendar for several years now... I always use your calendar as my principal diary for appointments, events and reminders, both at work and at home, as there is always a beautiful image and interesting notes to study each week. I hope that you will continue to produce this fine product.--Mick R., Sault Ste. Marie, Canada
