September 29: Science Highlights Livestream (3 hours)

05:30 PDT / 08:30 EDT / 12:30 UTC / 14:30 CEST

A program featuring members of many of the Rosetta science teams discussing the scientific accomplishments of the mission so far. I look forward to hearing both about what Rosetta has accomplished and what work there is yet to do on the mountains of data returned by the spacecraft.

To watch: Tune in to the livestream viewer at rosetta.esa.int or via https://livestream.com/ESA/rosettagrandfinale or ESA's Facebook page. I'll be Tweeting.

September 29: Rosetta's final maneuver

13:50 PDT / 16:50 EDT / 20:50 UTC / 22:50 CEST

From an orbital altitude of 19 kilometers, Rosetta will fire its engines to cancel out its motion and begin a slow free-fall toward the comet's surface.

To watch: Check for updates at the Rosetta blog and via Twitter through the spacecraft’s account @ESA_Rosetta and @esaoperations. (I'll be doing the same, as there will not be an event at ESOC for this moment.)
