The Week in SpaceJuly 19-25, 2010
Depth Perception This image by the Cassini spacecraft could easily pass for minimalist abstract art, but the simple lines and curves of the composition belie an elegance grounded in the complex. Saturn’s icy moon Rhea, its second largest with a diameter of 949 miles, reveals a variety of impact features on its dramatically illuminated surface. The bold horizontal line is a nearly edge-on view of Saturn’s magnificent ring system, reduced to a plane that seems ready to disappear. The rings begin over 200,000 miles behind Rhea and reach 40,000 miles back toward the planet. The canvas for this masterpiece is the cream-colored cloud tops of majestic Saturn itself, more than 300,000 miles beneath Rhea. This Saturn family portrait was taken by Cassini in 2007 when it was approximately 770,000 miles from Rhea.

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
