It wasn't a hot summer day, but NASA took a pass through a planetary sprinkler of sorts anyway. The space agency on Friday released the first dramatic photos of the Cassini spacecraft's, including a dip in its mysterious plume.
The craft on Wednesday screamed through the spray of water, ice and other materials shooting out of cracks in the moon's frozen surface. It passed within just 30 miles (48 kilometers) of Enceladus' surface at speeds over 19,000 miles (30,578 kilometers) per hour in order to collect samples of the strange spray.
Cassini has on-board instruments that sampled gases and particles as it flew through the geyser. Researchers on Earth will comb through the data over the next several weeks in hopes of finding insights into what is happening on and inside of Enceladus.
The moon is believed to harbor a global ocean beneath its icy shell. Scientists also think that there may be hydrothermal activity on the ocean floor that keeps it heated and perhaps even.
"Cassini's stunning images are providing us a quick look at Enceladus from this ultra-close flyby," said Linda Spilker, Cassini's project scientist at NASA's Jet Propulsion Laboratory, in a release. "But some of the most exciting science is yet to come."
Cassini launched in 1997 and has beenfor well over a decade.
