New Starship launch attempt on November 17 approved by FAA [updated]

The FAA has issued SpaceX with a licence this week to try a new Starship launch attempt

That attempt is now scheduled for 17 November was initially scheduled for 17 November, but postponed, due to necessary repairs on a grid fin attenuator, to 18 November, with the window opening at 13:00 UTC and running to 15:39 UTC. Back-up dates are Nov 18 to 20.

The test flight is similar to the previous failed one from April 20: launch is from Starbase (Boca Chica) in Texas into a 26.4 degrees inclined orbit with apogee at 235 km, splashdown is just short of one revolution to the NE of Kauai, Hawaii, 1.5 hours after launch. One can debate the semantics on whether the launch is orbital or suborbital.

The map above shows the flight path and the hazard zones from Navigational Warnings NAVAREA IV 1322/23 and HYDROPAC 3578/23 (the text of these warnings is given below)

Most of the flight is over Ocean and chances of sighting the spacecraft while on orbit are slim: passes over land are either in daylight, or with the Starship spacecraft in earth shadow (the latter is the case for e.g. Australia and Indonesia). 

On Kauai and Oahu in the Hawaii islands, the reentry fireball might be seen in the northern sky, if  Starship gets that far.

This is my estimate for the approximate orbit:

STARSHIP                       for launch on 18 Nov 2023 13:00:00 UTC
1 70000U 23999A   23322.54166667  .00000000  00000-0  00000-0 0    05

Let's see whether Starship will reach orbit this time.

 

UPDATE:

 
Starhip separated succesfully from the first stage this time (which violently disintegrated directly after separation), but Starship's auto-destruction mechanism destroyed the spacecraft just before engine shutdown and orbit insertion, at an altitude of about 148 km.
