Here’s the launch replay. The pre-launch portion is quite informative and well worth the time (about 15 minutes).
Wow, be sure to watch the first-stage landing, it was superb! Actually the whole presentation was one of the best I’ve seen.
Previously. . . SpaceX is set launch the CRS-17 mission utilizing the Dragon cargo-spaceship and the Falcon 9 rocket.
Launch is at at 06:48 UT / 02:48 ET. (thanks)
Coverage should be about 15 minutes prior to launch.
Replays when available.
