Thread for PLD Space's first launch. I think there is a mistake in the Twitter post. I believe the launch window starts at 31 May (not 30 May) at 8 am local (06:00 UTC). The YouTube stream is counting down to 31 May at 03:30 UTC (5:30 am local). Also, I believe it is not CET (Central European Time at UTC+1 hour) but CEST (Central European Summer Time at UTC+2 hours).

More information from PLD Space CEO. The issue is with a GSE tank not providing liquid oxygen to the vehicle at the rates they expect. Count is in a hold in order to investigate.

This is what Elon could have named the first StarShip launch, "A technology Demonstrator".

PLD Space is scrubbing the launch of Miura 1 today due to unfavorable weather conditions.

The company states the upper level winds, the only watch weather item, are no go for flight.

Teams will reset for another opportunity in the following days.

The high-altitude winds forecast for this weekend in the launch area, and with the last radiosonde carried out, violate the forecast limits and do not allow the launch operations of #MIURA1 to proceed. We postpone until a new scheduled window. @PLD_Space #VamosMIURA

Abort!  Circa 1 or 2 seconds after ignition.  The engine stopped firing during the moment changing from the close-to-pad camera to the erector camera.

Several quick ventings from what is, I assume, near the top of the first stage.

I don't speak Spanish.  Any explanation of what happened?

The webcast hosts speak before signing off.

We have had an automatic Abort due to the NO release of the avionics umbilicals, the rest were free and the engine at nominal thrust. 0.25 second margin. #MIURA1 is healthy. We analyze the data to have more information.

We had an impeccable countdown, with excellent coordination with @intaespana . The conditioning of the launcher, engine start phase up to nominal thrust was perfect. The performance was excellent. What could happen? 👉 🧵

Quote
It is still too early to obtain the final conclusions, we are still working on it, but we are clear that the Helium umbilical had a release delay of about 100 milliseconds...

Quote
This fact caused the “delay” between it and the avionics umbilicals to interrogate loose/not loose to overlap, and they coincided. Faced with this situation, the ground software safely aborted takeoff.

Quote
We were less than half a second away from taking off (nominal thrust 3.85s and release at 4.3s). The check routines at that critical time of <0 , 5s aborted our takeoff.

Quote
After shutdown, it is true that the situation is very tense, but everything is checked quickly. The agility of the CEDEA team @intaespana was also key for the operations to be safe.

Quote
We will finish the full study of the launch attempt and come back soon with a new launch date, summer and heat permitting. One thing is certain @PLD_Space does not give up. We are a professional and capable team. Flying is a matter of time #VamosMIURA !

We postpone the launch of MIURA 1 to September due to the mandatory compliance with the regulations regarding prevention of forest fires, the high temperatures in Huelva and the necessary coordination with the Civil Guard.

Wow, what a limiting factor to launching.  They won't be able to make money if they have restrictions like this.  Need to change the thread to NET September 1.

The restrictions apply to this location as it is highly prone to forest fires in this time of year. We're basically near, at, or above 40C for the greater part of the summer and adding a rocket into the mix doesn't help when the location is next to a natural preserve. Miura 1 is only flying twice, maybe three times tops. Then it's all from French Guiana with Miura 5

Off to Huelva!

MIURA 1 is back at the launch base after the summer!

We are in conversations with INTA to announce our next launch attempt window soon!

Feeling ready to do ambitious things and dream big.

Flashback ok MIURA1 Full Mission Test Happy First Anniversary

Quote
Sep 15, 2023
MIURA 1 SN1 Happy one year full mission test anniversary to MIURA1 SN1.

A milestone that taught us to not be afraid to fail, and that every lesson, big or small, is a step forward and part of our story.

As we look back to move forward, we are excited for what’s to come at PLD Space with upcoming MIURA 1 SN1 launch attempt and the engineering and production of our future orbital launcher MIURA 5.

From the summary, which I've attached.

Quote
3. WHAT HAPPENED?

PLD Space has determined a most likely cause related to the self-abort of the MIURA 1 SN1 lift-off.
In this case, it has been determined that an inaccurate measurement of a tilt sensor on the platform mast caused the platform to be positioned 1 degree off its intended position. This generated a difference in pretension in the steel tensioning cables that pull the umbilical cables and, as a result, the umbilicals took 100 milliseconds longer than expected to release from the launcher, which meant that, at the time of the software check, the umbilical cables were to all intents and purposes still connected.

Given this situation, and although the umbilical cables were released, the software automatically deter-mined, as a safety measure, that the umbilicals had not been released, and consequently sent the com-mand to abort the launch. The behaviour of the ground software was correct and as programmed.

4. WHAT HAVE WE DONE TO SOLVE IT?

1. Change the sensor, to try to get better accuracy in strongback tilt acquisition. This may help but does not fully solve the problem given the size of the structure, the dynamics of the hydraulics and the small margin of error.

2. Increase the time settings for the release of the umbilical cables in the ground software, which would help to cover additional eventualities.

Bold Test mine.  That's going to be difficult to test. The heat generated from engine startup might cause the tension to slacken. A windy situation could also cause that. Even a very hot day could affect the cables. Looks like they may need some hot-fire exercises to test the reconfigurations.

Thanks, Steven for posting that.

They did change the timing of when they test if the umbilical has been released. The problem last time was that the test was too close to the actual separation time, so that a 0.1 s delay in separation caused the test to indicate that separation had not occurred. Presumably, they have done tests to measure the variability of the separation timing, to make sure the test is after the latest the separation could occur, plus some margin, while ensuring that a late separation won't interfere with the launch.

Pre-launch operations are progressing nominally and the latest weather report is favorable.
Below, we review the main keys to the MIURA 1 launch.

Key flight figures:
- 12 minutes total flight duration.
- 6 minutes of microgravity time.
- 80 km apogee suborbital flight time.
- 4 hours to recover payload after the flight.

We are not flying alone!
The MIURA 1 SN1 mission is carrying an experiment from the German Center for Applied Space Technology and Microgravity @ZARM_de, which aims to study microgravity conditions.

The burn was only about two to three minutes.
MaxQ was their minimum success criteria for SN1.

Some screen grabs of the launch.

The engine flame disappears in one frame.

We then see a light streak.

The burn was only about two minutes.

As per the press kit (page 10), the nominal burn duration is 110 seconds.

Looks like a deck of cards was released inside the nose cone, which then settled at the tip as vehicle re-entered the atmosphere.

Those were photographs of PLD Space workers.

Left a brief summary on twitter based on what was said on livestream. Might have underperformed but gathered data from all the phases of flight they wanted. Still, we'll wait to see what they release once they look through all the data and more importantly, the rocket made it back. Now to see if they can find it in the dark Atlantic

MIURA 1 successfully launched, although it did not achieve its target altitude of 80km, instead topping out at 47km. I'm sure the team got a ton of useful data nonetheless, and they do plan to recover the vehicle itself for further investigation.

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.)?

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.

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.

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 !

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!

Some Conclussions of the Press Release:

-MIURA1 reached 2600km/h.
-The subsonic phase was much more demanding than expected.
-More than 1000 points of improvement have been identified for implementation in MIURA5.
-It has not yet been decided whether the second MIURA1 will be launched.
-7 new test benches are to be built in Teruel.
-There are no plans to sell engines.
-MIURA5 is expected to be used in different spaceports (not only in GUYANA).
-Development of all MIURA5 subsystems is progressing well and they plan to do the first subsystem tests by the end of 2023.
-MIURA5 stage separation mechanisms are already being tested.
- First MIURA5 launch planned for 2025/2026.

Trajectory was flattened because of upper-level wind analyses showing elevated risk of debris reaching the "near range" (launch pad, beaches and coast) in the event of an accidental or commanded vehicle breakup. Ran the line to the last moment to decide which trajectory to actually fly: instead of 80 km (initial plan) reach 50 km (actual).
Plots show the expected vs measured flight data.
As mentioned above, there was a challenging subsonic phase, due to larger than expected RCS action causing roll control authority anomalies, possibly caused by the large aft fins catching on the strong crosswinds between 1 and 4 km altitude. However, supersonic behavior was actually better than expected, and the oscillation didn't amplify, allowing it to fly true for the rest of the trajectory. Reentry behavior was also better than expected, and aerobrakes did well, even though their actual behavior was very difficult to model and large uncertainties remained pre-flight.
All ZARM payloads received their data as per contract.
A cheese wheel was flown as per current aerospace tradition for a maiden vehicle flight :) The "ahuyentalobos" brand was flown, which loosely means "wolf scarecrow" and hints at the "wolves" they had to scare off in order to succeed.
