Cassini took seven years to reach Saturn and has been there for 13 years. And this September, NASA is going to plunge the spacecraft into the atmosphere of Saturn — a spectacular end for one of the most scientifically rich voyages ever undertaken in our solar system. The beloved spacecraft was launched two decades ago and entered orbit around Saturn back in 2004.  

To help the mission process more data faster, we're running the Cassini data science challenge to develop an algorithm that can automatically detect anomalies in the rings.  

Dr. Tiscareno from the SETI Institute and the Cassini science team is here to answer your questions about the challenge, the spacecraft, the mission or Saturn itself!  Ask Dr. Tiscareno questions about Cassini, the science mission, and about Saturn and its rings below.
