The Cassini Imaging Science Team (ISS) has reported the discovery of a new
satellite of Saturn, designated S/2005 S 1, orbiting within the Keeler gap
in Saturn's outer A ring. The object had been previously inferred from the
presence of features observed on the outer edge of the Keeler gap and was
discovered in six images taken over 16 min on May 1 from a time-lapse
sequence of narrow- angle-camera exposures that were targeted to the
illuminated sideof the outer edge of the A ring.
S/2005 S 1 was subsequently found in 32 (7 km/pixel) low-phase images taken
of the F ring on Apr. 13 (spanning 18 min) and again in two high-resolution
(3.54 km/pixel) low-phase images taken on May 2, when its 7-km disk was
resolved. The satellite orbits Saturn every 0.594 days at a distance of
136500 km. The estimated geometric albedo is 0.5. The data at this time
are too coarse to yield any statistically significant orbital eccentricity
or inclination .

Also In a memo released today it was announced that a number of Cassini Flight team members are to be recognized with NASA Board Action Space Act Awards.
Although the announcement was released this week, the actual ceremony will
be held on June 21. Recipients include developers for LMBRRK and Predicts
software, Cassini Downlink and Reconciliation Architecture - Cassini
Downlink and Reconciliation Subsystem (CDRS), Cassini Main Engine Cover
Assembly, and Automation of Ground Processing to Track Spacecraft Memory.
