6:11 pm Spacecraft turns so its high-gain antenna can shield the craft from particles as it crosses Saturn's ring plane.
7:36 pm Engine begins burn, which will slow spacecraft down so it can be captured by Saturn's gravity. Burn lasts approximately 96 minutes.
9:03 pm Closest approach to Saturn of entire mission: 19,980 kilometers (12,400 miles) from Saturn's cloud tops.
9:12-9:22 pm Engine burn ends.
