Why is this on ESA section?

Do you mean it should go under:
1)  Suborbital instead? 
2)  Topic Heading change so that all European Launches include but not exclusively ESA?
3)  Other Launchers (Korean, Brazilian etc.)?

Do you mean it should go under:
1)  Suborbital instead? 
2)  Topic Heading align with all European Launches including but not exclusively ESA?
3)  Other Launchers (Korean, Brazilian etc.)?
4. Move it to Commercial Space Flight General like most other commercial companies?

Summary of events according to livestream:

- Miura 1 successfully lifted off and reached MECO.
- Apogee of ~47km, it was targeting 80km
- Despite this, the launcher met all ascent objectives on its first launch attempt, according to CEO.
- Miura 1 reentry test successful!!!

I think 2, 3, or 4 are the correct answers, since PLD has aspirations to perform orbital launches (and it would be awkward if the main PLD thread weren't in the same subforum as individual PLD launches). Of course, whatever happens should probably impact non-US commercial companies in general: while Indian and Japanese companies are generally reliably placed into the Indian and Japanese subforums, German companies seem to end up in Commercial Space Flight General, while British, Australian, and East/Southeast Asian companies are mostly there too but with occasional outliers ending up in the International/Other section (which seems to be primarily focused on government-led programs).

please no commercial - that is just a collection of random stuff, where it is difficult to find anything (plus it is inconsistent which companies are there and which are not)... rename this section to "European Launchers" and move all european stuff here (e.g. RFA)

#MIURA1 , technical details @PLD_Space : we reached a height close to 50km, compared to the 80km initially planned. The explanation is:

1) For safety, we change the trajectory to increase the portion of it over the Atlantic, “stretching it” and lowering the apogee

Quote
This was done to mitigate the affected area in the event of vehicle failure.

2) To avoid increasing the aerodynamic load too much, we reduced the engine thrust time from 122s to 103s. In addition, we had uncertainty in the real thrust in SL which was good for us to make this change.

Quote
We have shown that #MIURA1 is a robust vehicle to be able to “adapt” different trajectories successfully based on need. We have covered all the objectives and we have made history.

Quote
The maximum value now is in ourselves, our engineering and program development, our systems management, procedures and flight analysis. We are ready to take on the development of the orbita launcher #MIURA5 , the big thing is on the way!

Looks like the lower than announced apogee was due to a late change in trajectory and a reduction in the burn time to maximize safety.

We begin to recover the videos from the launch of #MIURA1 . There is a lot of AWESOME material. In this video you can clearly see the rocket's umbilicals releasing. A relief. #VamoeMIURA !

Very strange that the change in vehicle altitude from 80 to 50 km was not communicated to the public before launch. I went back and rewatched the livestream with English translated subtitles and could find no mention of the change. The commentators were presumably reading from a prepared script and said the launch was going to 80 km, along with a graphic also giving the same height. The reduction means the launch did not reach space by anyone's definition and would have greatly reduced the amount of zero-g time for the payload. The vehicle was designed to put 100 kg to 150 km.

Some of the flight control graphics were briefly shown. There was a call out of "46500" which could be height reached in metres (46.5 km). It was also mentioned that the cards seen in the nose cone are photos of PLD Space employees.

The original YouTube link has gone private, here is another that works. To get English change to auto _translate.

The thread title is showing a wrong launch time, liftoff reportedly took place at 00:19 UTC

Confirmation that recovery was unsuccessful, even though the parachute appears to have deployed and allowed for significant braking. No explanation as to what failed regarding the final descent and splashdown, although by reading between the lines I'm guessing something with the parachute is likely to have given way leading to a hard splashdown.

We continue analyzing the data from the first release of #MIURA1 @PLD_Space and the videos continue to honor the epic feat. The vehicle's active fluid umbilical release system and release mechanisms worked perfectly. ✅ #VamosMIURA !

Quote
There was no damage to the ramp except for the fireproof covers of equipment and pipes that were torn off by the engine fire, something that was foreseeable and unimportant. No hydraulic equipment or sensors were damaged. ✅

Technical update: Re-entry of #MIURA1, secondary flight target.
------
Vehicle re-entered with excellent aerodynamic braking, ejected braking parachute and braking parachute opened nominally (photo of previous qualification test performed).

Quote
#MIURA1 splashed down within the safety zone and within the planned splashdown area. Ships were outside the exclusion zone and took just over 1.5 hours to reach the zone.lost telemetry prior to splashdown, commanding vehicle passivation.

Quote
We collected a huge amount of aerodynamic data from the vehicle during re-entry, accelerations in various Mach regimes, something key to the development of the #MIURA5 re-entry strategy.

Quote
However, from the attitude data we believe that the water impact was lateral, an unfavorable load case and possibly the vehicle had an ingress of water that totally or partially sank the vehicle. Recovery efforts were unfeasible. After 8h we aborted the search.

Quote
As a reflection: since 1957 there have been ~6500 launches of which only 2 rockets (I don't consider the space shuttle) are reusable (Falcon9 and NewShepard). Total recovered rocket launches account for 3% of the total. Electron has recently been added.

Quote
What do I mean by this? It is obvious: recovering a rocket is as (or more) complex than launching it and it is understandable that doing it the first time is not possible. For us it was something secondary and sooner rather than later, we will achieve it. #VamosMIURA! @PLD_Space

Quote
Recovered or not recovered we are equally happy and satisfied with the success!

This is the last photo of #MIURA1 that I was able to take before its release. Also the first photo without him. It is something very emotional because this rocket made us make history and the entire team @PLD_Space will always be grateful. He did his job excellently. #VamosMIURA
