Blue Origin's crew capsule has landed back in Texas after an unplanned in-flight abort. The capsule is flying NASA-sponsored experiments on today's flight, but no people.

The spacecraft fired its solid-fueled abort motor about a minute after liftoff.

Couldn’t tell if the booster fell back and RUD’ed on the ground, or it continued to thrust upward.
Considering that the engine catastrophically failed and the booster was visibly tilting off-axis as the capsule separated, I think it's very unlikely that the booster remained on any kind of controlled trajectory. The question is whether it fell back to the ground in one piece, or broke apart (or was destroyed by range safety) in midair.

I am looking at the El Paso Radar at the different scan angles right now, there are no signatures north of Van Horn that would be indicative of a debris fallout. My guess is that the booster stayed intact.

Have to commend the webcast host. Stayed cool and professional throughout the anomaly.

What luck nobody was onboard.  How many crewed versus uncrewed flights have there been since they started flying crew?

Glad to see the abort system working as intended, and that the crew (presumably) would have been safe if onboard.

It does look to me like the engine exhaust flashed a couple of times prior to failure, which could indicate engine rich exhaust prior to engine failure. Great demo of the crew escape system.

It was also around MaxQ so they would have been changing the throttle on the engine, sometimes that means passing through engine operating speeds which are not kind to the hardware, I don’t know enough about BE-3 to know if this is a possibility.

I would call this a successful failure. The Crew Capsule landed safely while the booster failed.

Exactly one minute of dead air passes between the anomaly and the resumption of the commentary.  That's a *lot* of time.  To their credit they did show everything (and the youtube video is still up, for those like me who did not see it live).  But I wouldn't say that a minute of silence (which felt a lot longer) is particularly commendable.  Not anything I would be upset about either.

This was the ninth flight for this booster and capsule.

Presumably the abort motor is not swapped out between flights? If not, then they might have some interesting data for an abort motor that is 4 (or so) years old and has been subject to flight forces 9 times. I hope someone asks them about that whenever they do a press conference for this.

The first crew flight was July 2021, Blue Origin has done 6 crew flights total. Since first launching people, they have only done two cargo flights, however this was the 9th flight for the cargo NS + capsule.

This looks like, uh, nozzle/pipe/combustion chamber breach? Or TVC problems?

OK TIL that BE-3's both turbopumps "hang" on the outside like this with the combustion exhaust gas running off the sides in this combustion tap-off cycle engine.

That seems to hint at one of the turbopumps failing, hanging on for ~3s before quitting..

What we do know is that Blue Origin has had an exceptional safety record heretofore with New Shepard, with no significant problem on its previous 20 flights. Also, this booster was not human-rated, unlike Booster 4, which is used for crew flights.

I didn’t know that Blue have different classes of boosters?! Wow, is that ‘just’ differences in assurance or even differences in design?

In a statement, the FAA says it will lead the investigation into the uncrewed Blue Origin mishap. Says no injuries have been reported. The FAA will have to sign off before New Shepard can return to flight.

Quote
FAA Statement
The FAA will oversee the investigation of Blue Origin's NS-23 mishap that occurred at its Launch Site One location in West Texas.
The anomaly that occurred triggered the capsule escape system. The capsule landed safely and the booster impacted within the designated hazard area. No injuries or public property damage have been reported.
This was a payload only mission; there were no humans aboard.
Before the New Shepard vehicle can return to flight, the FAA will determine whether any system, process, or procedure related to the mishap affected public safety. This is standard practice for all mishap investigations (faa.gov].
The FAA is responsible for protecting the public during commercial space transportation launch and reentry operations.

NS-3 was originally intended to be for crew flights, but ultimately never was used for that. NS-4 was built after lessons learned from that process, so presumably there are some design differences. To my knowledge, what, if anything, is different is not public information. It could be as simple as adding some structural strength in key areas or redundancies in key systems, but unless Blue Origin makes a statement about this, we won't know for sure.
