But DE, SE, and ES are the official two-digit ISO 3166 country codes for Germany, Sweden, and Spain, respectively. The ISO 3166 country code for Greece is GR, not ES.

However, el is the official ISO 639 language code for the Greek language (lowercase, not uppercase!). So for some reason, someone decided to use the uppercase Greek language code to denote the country of Greece. (the two-digit ISO 639 language code for Sweden is sv, so it’s not even consistent)

As /u/Successful_[email protected] pointed out, they apparently use the VAT identification number for this image.

Das hier scheint die Bildquelle zu sein.

The link is broken, because it is attempting to create a new archive.org snapshot whenever someone clicks on it.

Selbst wenn Biden jetzt seine Kandidatur zurückzieht, wüsste ich nicht, was irgendjemand diesem Bild entgegensetzen könnte.

Wow, it really seems to be one of those crypto scams, you are right! I specifically checked for this, but apparently, I was fooled!

I was suspicious of the -2024 suffix. Things that tricked me:

  • 139k subscribers: I guess this channel just renamed itself?
  • Lot’s of official esa videos on the channel: Apparently, it’s just playlists.

I will redact my post to remove the cryptoscammer link. So far, no cryptoscamming was observed.

I was just watching the countdown to todays Ariane 6 flight on YouTube on the ~~official~~ cryptoscammer European Space Agency channel. The preview animation video that they are looping looks stunning, but something seem off …

3 weeks, roughly in line with faster Space Shuttle turn around times

The shortest shuttle turnaround time was 55 days. Almost three times as much as Falcon 9. The fastest post-Challenger turnaround time was 88 days, I believe. After Columbia, the fastest turnaround was around 5 months.

NASA claimed that the shuttle could achieve a turnaround time of two weeks (page IX). It looks like SpaceX is not the only one setting unrealistic timelines?

Without UEFI, the boot process is different for each device, requires a custom boot loader, or at least explicit support by the operating system. Is your laptop going to be supported by the distribution you want to use? What about in 5 or 10 years? With UEFI, the boot process is standardized, so it should just work.

I just compared the footage from various points in time. The flap positions for T+00:48:12 (pre-entry) and T+01:05:41 are almost the same, then it rotates about its rotation axis until T+01:05:44, but suddenly it starts to rotate about ANOTHER axis, and at T+01:05:47, its at a completely new angle. I think T+01:05:44 is the point where the flap finally breaks (after touchdown, but before splashdown).

I think we have seen motion as fast as the one at T+01:04:22, but the subsequent bounce is surprisingly strong. I still think that the flap was still under some control at that point.

I heard rumors on reddit that SpaceX deliberately removed a single tile on this flap for testing purposes, but I could not find any reliable confirmation for this. They deliberately removed tiles on the engine skirt, though.

I expect the flap on the opposite side of the ship experienced a similar level of destruction. Well, that depends on whether the damage occurred because of a general loss of structural integrity because of excessive heating, or if specific localized damage on that flap allowed plasma to penetrate the heat shield, resulting in the damage that we observed. So, general structural failure vs. random damage at that location cascading into a hole in the flap.

Anyways, I am pretty sure that the complete loss of control authority on one of the flaps would be catastrophic. But the movement that we observed seemed pretty deliberate and consistent to what we saw during the suborbital test flights. Especially the unfolding of the flap at the T+01:05:42 mark is EXACTLY what we saw during the high-altitude flights, e.g., see SN8 @ T+6:33 or SN9 @ T+6:18. The forward flaps are folded back at first, and then rotate into a position perpendicular to the surface of Starship. The movement (for IFT-4) is precise, consistent with previous flights, and stops abruptly in the correct position.

That was some Columbia-level damage that Starship experienced during reentry, and yet it successfully retained control authority, completed a soft landing, and everything was live streamed. Amazing!

The booster seems to be almost ready for the first catch attempt (depending on the accuracy of the landing).

I wonder to what extent they can retrofit Ship 30 to reinforce the hinge of the flaps, and how long that is going to take? On the other hand, the ship did survive, so maybe they will just repeat the launch without any major fixes, and try a few different things? (Deorbit burn, maybe even suborbital test-mass deployment, or more aggressive tests of the heat shield?)

The next-generation Starship design has less exposed flaps with reinforced hinges already. But is it already in production?
