ExoMars update: Timeline for separation and orbit insertion

ESA is now maintaining a live blog with ExoMars arrival updates, and several bits of news appeared this morning:

ESA has also released their press kit for TGO orbit insertion and Schiaparelli arrival. If you have any questions about the spacecraft, their instruments, or their mission, you'll likely find them answered in the press kit!

At the time of ExoMars arrival, the one-way light time between Mars and Earth will be 9 minutes 45 seconds. I've copied the timeline from the press kit below and converted it to various time zones for your convenience. All times below are Earth received time -- so for events at Mars, this is the time we can expect to receive information here on Earth of the events that transpired about 10 minutes before on Mars.
