Cassini begins transmitting data from Enceladus flyby

Washington, August 13 : The Cassini spacecraft has began sending data to Earth following a close flyby of Saturn's moon Enceladus.

During closest approach, Cassini successfully passed only 50 kilometers (30 miles) from the surface of the tiny moon.

Cassini's signal was picked up by the Deep Space Network station in Canberra, Australia, and relayed to the Cassini mission control at NASA's Jet Propulsion Laboratory in Pasadena, California.

"We are happy to report that Cassini's begun sending data home," said Julie Webster, Cassini team chief at JPL. "The downlink will continue through the night and into tomorrow morning," she added.

Closest approach occurred at approximately 3:21 p.m. PDT (Pacific Daylight Time) on August 11th, while Cassini was traveling at a swift 17.7 kilometers per second (40,000 miles per hour) relative to Enceladus.

During the flyby, Cassini focused its cameras and other remote sensing instruments on Enceladus with an emphasis on the moon's south pole where parallel stripes or fissures dubbed "tiger stripes" line the region.

That area is of particular interest because geysers of water-ice and vapor jet out of the fissures and supply material to Saturn's E-ring.

Scientists hope to learn more about the fissures and whether liquid water is indeed the engine powering the geysers.

"There is a lot of anticipation and excitement about what today's flyby might reveal," said Bob Pappalardo, Cassini project scientist, also of JPL. "Over the next few days and weeks, the Cassini teams will be analyzing the photos and other data to tease out new clues about this tiny, active world," he added.

Two more Enceladus flybys are planned for October.

The first of those will cut the flyby distance covered by Cassini on August 11th in half and bring the spacecraft to a remarkable 25 kilometers (16 miles) from the surface.
