An updated ephemeris for the rescheduled Artemis launch time (window opens on Sept 3 at 18:17 UTC) is on JPL Horizons. This has much better visibility for us on the evening of the launch. The spacecraft rises around 20:00 UTC and gets above 40 deg altitude by 21:00. The upper stage separation burn is at T + 2hr 7min so may well be visible from the UK if the sky is clear.

Let’s hope that they now fully understand the LH2 bleed and the RS-25 cryogenic conditioning problems that scrubbed the last launch and that the weather cooperates on both sides of the Atlantic.
