General Discussion / Re: SpaceX no longer reliable.

It has been reported that the likely culprit was a COPV exploding.  It seems to me that a few years ago a F9 suffered a similar incident that was identified as a COPV. COPVs are lighter but are not as reliable as steel, IMO.

They've found a new way to drive efficiency. Just blow 'em up on the ground without all that lifting into the upper atmosphere nonsense. Musk is a genius!!!

I understand Musk isn't an engineer, but he seems to like to play at being one. Like the story I've read of him getting onto some part of a Tesla production line and asking the workers why they use that many bolts in that stage of manufacture. Or his interview with Tim Dodd (Everyday Astronaut) which ended up in some change in the design of Starship.

I wonder whether the problems Starship has been experiencing over the last few months are anything to do with other tinkering by him. Or is it simply that the SpaceX engineers have pushed Starship beyond current technological limits?

Scott Manley also reports on it, with the title tag "Not Nominal" :-)

Oh dear....

I'm no expert in rocketry by any means, and most of what I do know I picked up from here, but surely we've generally got past the problem of rockets just blowing up on the pad, haven't we?

We got an agency arresting  US citizen, even though it has no right to do so, in one case for asking for a judicial warrant the agency needed to make another arrest in the location. We have  a sitting senator being handcuffed for wanting to ask a question.
History is rhyming like a rapper spitting verses like a GAU-8

I'm not a liar Jarrah, I just think your ill-though out badly evidenced claims are bullshit. I also don't need your permission to quote you however I see fit .

Late to this post, but my friend helped my mindset today after a torrid time at work:

Arguing with idiots is like playing chess with a pigeon. No matter how good you are the bird is going to crap on the board and strut around like it won anyway.

TIFO that Saturday 14 June 2025 is No Kings Day.

I have no intention of encouraging people in the USA to go to protests which could have unpleasant consequences for them. But still, I thought I'd at least mention it.

The intent is to have protests everywhere but DC.  We're going to our local one.  I doubt ours will get shooty, but I can pretty much guarantee some of them will.

Well, congratulations USA. Millions attending the No Kings protests, and maybe tens of thousands attended the birthday parade.

I noticed the marching was pretty slipshod, and the crowd was quiet enough that Fox had to dub in cheering...

The Hoax Theory / Re: Watching the detectives...

As far as the "hole" is concerned, they're backtracking a little now - claiming that it was AI what made them say it, mainly because Jarrah has weighed in with an equally incorrect claim that it is a hole in the actual positive film. A hole that has changed size and shape over time.

Yeah right.

Anyhow, their latest effort has latched on to a different claim:L the tarnsition from 12 fps top 6ps in Apollo 11's magazine H of th e16mm film: the ascent from the surface. For some reason they're picking on interpoloated footage, rather than an unprocessed version. amnd because they find all kinds of extra things in there (you know, the kind of things entirely consistent with AI interpolation), then there must be some sort of faking going on.

The best bit is their insistence that the frame rate change represents an edit, and is really the transition from them filming over a model to filming lunar orbit images or some such garbage.

Here's your challenge "Detectievcs": find the lunar orbiter images that show the detail of the area that is contained in the Apollo 16mm footage. I'll even tell you which ones you need to look at: Lunar Orbiter 4, images 84 and 85.

You can get them here:

https://planetarydata.jpl.nasa.gov/img/data/lo/LO_1001/DATA/LO4/

Here's just a tiny example, taken at the point they get all excited about. I've rotated the AJF version of the 16mm footage



to match the LRO view.




Now let's zoom in to the area in the red box:



This is the best Lunar Orbiter view of the same wide scale area:



Where's the detail "detectives"? Where are all the craters and rocks that the 16mm footage picked out?

Lunar Orbiter images did not contain the detail required of the Apollo landing sites to produce a model of any kind that would show the detail in the 16mm footage and photos. You can claimn it was a model all you like, but how did they make it with information they didn't have?
