A stunning image of Saturn’s rings. There are two moons in this image too, the larger of the two is obvious and is Epimetheus and the other is Daphnis.
Daphnis is a wee moon being only 8 km / 5 mi. and is very difficult to see unless you click the image to get the larger view. Look just to the right of center and in the rings just to the inside of the (Keeler) gap.
Before you read the NASA supplied caption below, I wanted to let you know there are TWO different launches today and they are only a short time apart from each other:
1. The Progress 53 cargo ship is scheduled to launch from the Baikonur Cosmodrome in Kazakhstan at 20:53 UTC (15:53 EST) The coverage should be here: http://www.nasa.gov/multimedia/nasatv/ustream/ Update: Launched,
2. A SpaceX launch is scheduled for 22:45 UTC (17:45 EST). The flight will put the SES-8 communications into a geostationary orbit from Cape Canaveral Florida USA. Coverage: http://www.spacex.com/webcast/ Update: A delay due to an issue, next attempt not before Thursday. The delay came around T minus 3 minutes 40 seconds. I could not get back to the time and a news release with more info is still in the works.
Here’s the caption from NASA (link goes to much larger versions of the image):
Amidst and Beyond the Rings
While the moon Epimetheus passes by, beyond the edge of Saturn’s main rings, the tiny moon Daphnis carries on its orbit within the Keeler gap of the A ring. Although quite different in size, both moons create waves in the rings thanks to their gravitational influences.
