Wow at the instant "they must not want to us to see them fail!!!" speculation on the no camera announcement.

As I recall, last time they did not show camera it was a regulatory issue with NOAA in regards to Earth imaging (it really was). Maybe they let their license run out?

That was on the Second Stage video feed. The first stage was still broadcast during that flight as it didn't show a wide swath of the Earth.

... people got to remember spacex is more than allowed to try and hide failures or control the messaging to avoid bad press, no one was forcing them wen they user to show off failures of Falcon 9.

Of course they are allowed to try and hide their failures, but I would be utterly flabbergasted if this becomes their policy after 19 years, 111 orbital launches, and a few dozen test launches. During that time they never hid their successes or failures, even to the point of making a Video about how *not* to land a Falcon 9 booster.

Why I vaguely recall them livestreaming the two most excellent KaBooms just this year, already. That surely does not seem like someone who "try and hide failures" to me!

Oh absolutely this isn't a very new policy. This was adopted when landings became routine in 2017 and 2018. In most of spacex's history they gladly showed off the faults of falcon 9 and 1 but mainly in recent history - even though Starship they gladly show off - they cut the feed (CRS-16) don't even show the feed at all (Starlink L5) or media blackouts (every fairing recovery failure in the past 18 months or more, every landing failure from STP-2 onwards).

Elon Musk even specifically said that it was a mistake to cut away from the CRS-16 failure and that it would not happen in the future (meaning they'd always show their failures).
And that's why I love the man, if it wasn't for Elon there would've been media silence on CRS-16 as well.He was also a major contributor to the How not to land an orbital rocket video, wasn't a SpaceX PR team made video. But to be fair Elon is kinda the SpaceX lead PR team member.


I will say it again, I will be glad to be proven wrong and they fix the camera during downtime or on the next flight the camera is working again. But people need to remember SpaceX doesn't owe us anything, just because they used to give us info and video on Falcon 9 failures doesn't mean they still have to.

Okay if this discussion needs to continue, then don't forget that the announcer also stated that the landing on the droneship would be broadcast as usual.

So they don't want us to have a camera view of a possibly failing booster in flight (when we really can't see anything all that dramatic) but are okay for us to see one slamming down on the droneship if the failure occurred in the last few seconds?

I just thought of another WAG that doesn't involve SpaceX suddenly becoming camera shy -- they repurposed a camera and video feed to watch something they wanted to see. Maybe those protective boots we heard were the cause of failure on the other one, maybe something else that they wanted eyes on if it failed and they couldn't recover the booster. But in this case yeah ITAR and their own trade secrets could keep them from wanting to show it to the public -- plus the fact it would probably not be very interesting.

SpaceX engineers have mentioned before how nice it is to be able to stick a Go Pro next to a part to be able to get a visual record of how it was behaving in flight, but if you don't get the Go Pro back you need to assign video bandwidth to it.

There won’t be a Falcon 9 launch tonight.

The next chances to launch the Falcon 9 from pad 39A will come at 3:24am EST (0824 GMT) or 5:42am EST (1042 GMT) Thursday.

The morning launch suggests SpaceX will target a different plane in the Starlink fleet.

What is the range conflict? There are no other orbital launches scheduled in that time slot.
Static Fire for the next Falcon 9 flight (launch March 8 UTC)?
Trident II test offshore (USA or UK)?
Previously scheduled range maintenance?

Has anyone heard anything about the cause of the auto-abort of the countdown Sunday night?  This thread has been far more interested in why the first stage camera views would not be made public than why the bird didn't fly.

I know I haven't seen anything from Elon in the twittersphere, but figured I could maybe ask if it's been discussed here, but in some other thread, where I wouldn't think to look...?

Oh, I shall.

I already adjusted the "OP" back in reply #29 with today's update, and changed the beige print to tan. Agree beige reads very poorly against a default white background.

FYI to the curious:
One can substitute further text colors beyond the pull-down pallette provided by manually substituting the color name, or by hexadecimal red/green/ blue code.

No.  They coordinate with each other on ops that affect each other
