Here’s the video from the first part of the coverage – data acquisition.
Ultima Thule flyby signal acquisition comes first at 14:45 UT / 09:45 ET. I’ll leave the link up for the post flyby press conference a couple hours later (16:30 UT / 11:30 ET).
Note: it is 15:15 UT and the coverage is about to start.
The spacecraft has data! Press conference in about 45 minutes @ 16:30 UTC.
