oddly Convair NOVA studies were mostly reusable, including NEXUS
I think that Krafft Arnold Ehricke play major role in this.

A New, Deadly Era of Space Junk Is Dawning, and No One Is Ready
A Saskatchewan farmer’s near miss with potentially lethal debris falling from orbit highlights the skyrocketing risks and murky politics of space junk

When Space Junk Fell on My Neighbor’s Farm, the Law Had Few Answers for Us

A Saskatchewan farmer’s near miss with potentially lethal debris falling from orbit highlights the skyrocketing risks and murky politics of space junk
www.scientificamerican.com www.scientificamerican.com

... Hope is not enough. SpaceX and other companies, as well as governments, are producing space debris that could very easily kill people. Countries need to enforce the rules that already exist, and regulations need to be updated to account for the unprecedented numbers of launches and reentries now occurring.

The hundreds of pounds of space debris that fell near my home were a clear warning. To avoid disaster, the nations of the world must heed it, and catch up with the reality of today’s commercialization of orbit before it’s too late.

As per NSF appears to have been a LOX leak on the upper stage.

SpaceX has an incredible track record with Falcon9. I can say from personal experience they are very transparent when issues arise. I have no doubt they will arrive at a cause quickly and ensure the most cost-effective and reliable launch vehicle keeps delivering payload to orbit. As for Polaris Dawn, we will fly whenever SpaceX is ready and with complete confidence in the rocket, spaceship and operations

Thanks Jared. We will investigate the issue and look for any other potential near-misses.

We are tracking to do more Falcon flights this year than Shuttle did in 30 years, the vast majority of which are uncrewed.

A major advantage of this super high flight rate is that we can identify and resolve problems that may only occur once every 1000 flights. This is impossible on a low flight rate vehicle.

The FAA requires an investigation on the mishap and grounds Falcon 9 for now

Especially as it’s manned rated they could do nothing else. Considering the state of alternative launchers at this time this will effectively ground US space for now. Vulcan’s next certification launch isn’t until September. Also knock onto Europe as Ariane 6 is still in very early stages and has its own issues. This failure couldn’t have come at a worse time.

The team made contact with 10 of the satellites and attempted to have them raise orbit using their ion thrusters, but they are in an enormously high-drag environment with their perigee, or lowest point of their elliptical orbit, only 135 km above the Earth
Click to expand...

Each pass through perigee removes 5+ km of altitude from the highest point in the satellite orbit. At this level of drag, our maximum available thrust is unlikely to be enough to successfully raise the satellites.

As such, the satellites will re-enter Earth’s atmosphere and fully demise. They do not pose a threat to other satellites in orbit or to public safety.

But likely to have other problems from moving too slow.
Use it or loss it become a major thing if you dont move fast enough.
Which can cause unnecessary pressure on launch authorities to get the payload up on schedule. Part of the reason for Challenger getting a go was to meet the deadline.

And generally speaking more is better for theses thing anyhow. You end up learning more and able better optimizate gear.

We basically moving into the late 1920s to 1930s era of Aviation Space wise. Things becoming both cheaper and more common.

Expect that there WILL be more issues as well.

Some of those issues are going to unavoidable. Theres like 6 aircraft accidents daily in the US Alone, over 20 world wide. Most of them is no one fault, everyone did everything right but basically God said F you.
 
The Space Bucket has just put out a video concerning the premature shutdown of the second-stage:


Last night during a routine Falcon 9 Starlink launch the vehicle experienced an anomaly with the upper stage. This led to an unsuccessful second burn and a deployment of the satellites into a lower-than-intended orbit. To put in perspective how rare this is for the company, it marks the first Falcon 9 failure in around 7 years after an over 300 mission success streak.
Click to expand...
Importantly, the FAA has issued a few statements regarding an investigation and a note that SpaceX won’t be flying the vehicle until the agency has confirmed it’s safe to do so. With quite a few Falcon 9 missions scheduled in the near future, this could have a decent impact on future launch dates. Here I will go more in-depth into the FAA’s statement, the Falcon 9 anomaly, upcoming missions, and more.

NASA Statement on the Falcon 9 Second Stage issue:

"Although the SpaceX Starlink launch was a fully commercial mission, NASA receives insight from SpaceX on all items of interest about the Falcon 9 rocket, as part of the agency’s standard fleet following activities. Crew safety and mission assurance are top priorities for NASA. SpaceX has been forthcoming with information and is including NASA in the company’s ongoing anomaly investigation to understand the issue and path forward. NASA will provide updates on agency missions including potential schedule impacts, if any, as more information becomes available."

At Starbase preparation for second Tower segment instalment are under way.
in same time some work is done on Launch pad with B12 on it, unclear what going on, repairs ?

the FAA came with this Hammer,
they want full report on Starlink 9-3 including modification to prevent it again
after that SpaceX can return to flight of Falcon 9

Falcon 9 returning to Port of Long Beach this morning after releasing a faulty MVac on July 11 during the Starlink 9-3 mission. The second stage developed a liquid oxygen leak leaving it unable to complete its second burn. Although the satellites were deployed, they were unable to reach proper altitude and will eventually break apart in Earth’s atmosphere. Should be quite a show in a dark sky!

Also just Realize something.

It was the SECOND STAGE that had the failure.

Not the first stage.

The secondary stage is the expendable one, it always a new fresh built rocket since they get used up in launch.

The first stage apparently rtb just fine.


Throw in that this is the second F9 second stage failure in like 10 years?

Unless it an semi obvious quality control failure it likely to be a one off we have no clue how that happened deal.

The First Stage is not the Probleme, its payload !
During Second stage malfunction is real danger that Payload can reentry and hit something.
worst case senario it reenter the atmosphere over populate area like Kuba and impact there
 
looking true that Data there only Starlink-11216 who able to get into low stable orbit for moment 235 x191 km
the rest will reenter in coming days like Starlink-11220, how to hell arrive that one into 116 km x 80 km orbit ?
what to hell happen during restart ? look more that second stage had exploded !
can it be that again a COPV tank failed in Lox Tank ?
 
V1 vs V2 hardware
oddly this hardware is Label for S33 Ogive

It appears that the IFT-5 launch is not far off, from the Space Bucket:


Earlier today only a bit over a month since the last Starship flight, SpaceX completed a full-duration booster static fire. With this, they provided multiple angles and videos of the event along with a handful of photos. Now that this static fire is complete, there are only a few more milestones and steps before Flight 5 of Starship.
Click to expand...
In theory, based on a few comments from both Musk and the company, this could end up being the first booster to return to the launch site and attempt a catch. Here I will go more in-depth into this morning’s static fire, what else needs to be completed, the upcoming launch, and more.

A Falcon 9 Stage 2 was just tested at McGregor. This is the first one since the Starlink 9-3 anomaly and could be a good sign of SpaceX's progress with the investigation.

Breaking news: Space Force has cataloged two objects from Group 9-3 launch that are still in orbit, in 182 x 296 km and 177 x 274 km orbits. Did the argon thrusters managed to save at least two of the sats? But there are no SupTLEs from these objects, suggesting they're dead

Musk move his Companies HQ to Texas
Because relationship between Musk and government of California deteriorate final point.

For moment the X HQ will moved from San Francisco to Austin (Texas), do chaotic situation in the City.
Next will be SpaceX HQ in Hawthorne moving to Starbase new office complex

Since SpaceX has build a Complex near GigaTexas and in Kennedy Space Center,
indicate that Musk is prepare to move the Hawthorne production also.

Statement from the @FAANews about the SpaceX Falcon 9 annomaly, and the now started safety investigation:
Click to expand...

"The FAA is responsible for and committed to protecting the public during commercial space transportation launch and reentry operations. On July 15, SpaceX requested that the FAA make a public safety determination as part of the ongoing investigation of the Starlink Group 9-3 anomaly. The FAA is reviewing the request and will be guided by data and safety at every step of the process.
When a public safety determination request is received, the agency evaluates safety-critical systems, the nature and consequences of the anomaly, the adequacy of existing flight safety analysis, safety organization performance, and environmental factors. If the FAA agrees no public safety issues were involved, the operator may return to flight while the investigation remains open, provided all other license requirements are met.

Bout what I expect to happen.

First major incident with the F9 in how long? With the only people hurt being SpaceX beancounters?

Isnt no reason for a All Stop Grounding.

I can see NO MAN FLIGHTs being a thing til the issue worked out. That I understand, but cargo flights?

This is basically grounding a aircraft with a LONG safety record for a none injuring crashing.

Something That should be looked at but not something which warrents a Stop All.


Especially with the Dragon being the only other man rated system with Skyliner being...

Not even a joke any more.

looking on what he achieve:

Start mass produce electric vehicle, becoming number one in manufacture of electric Cars.
gave us PayPal the backbone of Online commerce and finance transaction.
Revolutionise spaceflight with Falcon 9 and Starship reduce launch cost
The Boring company drill fast and economic tunnels
Neurolink a interface Brain and computers, show very promise results.
and soon humanoid Robots and A.I.

Yeah, he ist a weirdo, but the richest of all, who secure already His place in the History books...
