During Cassini’s tenth ring-grazing orbit, the spacecraft’s radar instrument will perform two observations of Saturn’s rings. For nearly two hours, when Cassini is in the segment of its orbit in which it is nearest Saturn, the radar will bounce signals off Saturn’s rings like a flash camera but with radio wavelengths of light instead of visible wavelengths. Radar scientists will use data from the observation to produce the first high-resolution radar image of Saturn’s rings.

In this ring-grazing orbit, the Imaging Science Subsystem (ISS), along with Cassini’s Ultraviolet Imaging Spectrograph (UVIS) and Visible and Infrared Mapping Spectrometer (VIMS), will study the structure and composition of Saturn’s upper atmosphere, including how hydrocarbons are distributed vertically. The VIMS instrument will also produce a mosaic map of Saturn’s north pole by staring at the northern hemisphere for 10 hours.

Thank you to everyone who has stuck by the YouTube channel and to all of our admins and forum users here on the channel.   They really have kept the website current while I have been busy taking care of things in my personal life.   I promised that the next video would be a long one and have a LOT to look at.  You can get lost in these Gigapans and I really hope that you do!  I spent a lot of time stitching these together and making sure that they were the best quality that I could get them.  SOL 1448 really has been a goldmine for anomaly hunters and those people who are just hobbiest.  I really hope you enjoy this one and expect much more to come from the latest batches of images!
