The PSCA has issued a notice for mission id P135, which per discussion in the ABL RS1 topic is Astra LV0009, so I created a topic for LV0009 at https://forum.nasaspaceflight.com/index.php?topic=55685.0.

In the terminal count, there was an interesting callout from the LD to the FSO, advising them to prepare to issue an 'option command' at T+164 (2m 44s into flight) calling out "an event". Going by the timeline that's just prior to MECO. AFTS is not armed and instead in shadow mode (FSO would not be inhibiting an on-board system, the FTS is fired by ground command) so something to listen out for on the next attempt.
Well, that turned out to be an opaque 'option enabled' callout.
Some news on the option/event mystery, the most recent stream had a more verbose callout on the countdown net:
Quote
Miffco (MFCO?), prepare to issue option when rocket IIP passes min MECO point and is within disperse trajectories calling out an event
And later:
Quote
- Flight, MFCO, option sent!
- FTS confirms option detected.
- Safety can't confirm.
- That callout of an option means that the system will be safely able to ignite the upper stage after-
- MECO
- our stage separation.

Sounds to me like part of their FSS involves only enabling the upper stage engine (from the ground, rather than autonomously) once the vehicle's instantaneous impact point has passed into a corridor, bounded by:
- 'min MECO point': the minimum distance the vehicle must travel before successful MECO (presumably to prevent a premature staging from producing a high velocity suborbital trajectory rather than a ballistic fall)
- 'within disperse trajectories': the maximum extent of first stage debris trajectories in the event upper stage ignition destroys the first stage

  Hope they get it figured out. Walking through a door that isn't opened tends to make for a rough day.

Man, it’s weird to see the stock react so extremely during launch. Having a publicly traded launch company is so extremely stressful. (I’m glad I don’t do any individual stock investing.)

ROSEN, A TOP RANKED LAW FIRM, Files Securities Class Action Lawsuit Against Astra Space, Inc. f/k/a Holicity, Inc.; Encourages Investors with Losses Over $100K to Secure Counsel - ASTR, HOL

Quote from: prnewswire.com
WHY: Rosen Law Firm, a global investor rights law firm, announces it has filed a class action lawsuit on behalf of purchasers of the securities of Astra Space, Inc. f/k/a Holicity, Inc. (NASDAQ: ASTR, HOL) between February 2, 2021 and December 29, 2021, inclusive (the "Class Period"). A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than April 11, 2022.

SO WHAT: If you purchased Astra securities during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

<snip>

DETAILS OF THE CASE: According to the lawsuit, defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose: (1) Astra cannot launch "anywhere"; (2) Astra significantly overstated its addressable market; (3) Astra overstated the effectiveness of its designs and reliability; (4) Astra significantly overstated its plans for diversification and its broadband constellation plan; and (5) as a result, defendants' public statements were materially false and/or misleading at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages.

This is routine legal trolling that is likely to happen any time there's sufficiently bad news about a publicly traded company.   Not remarkable in any way.

Astra is unique in that they openly pitched a strategy of compromising some reliability in exchange for lower costs, so they're the last launch provider that could be credibly accused of overstating the reliability of their designs.

This lawsuit combined with recent failure isn't helping share price.

Four failures in five orbital attempts, plus another rocket destroyed on the ground, doesn't look good, but if you look at the timeline of the failures and the one success, progress is visible.  They started with all sorts of ground processing problems.  Then they worked through flight control and propulsion problems.  Those early problems seem mostly ironed out.  Now they have the fairing issue.  If they can figure that out they have a chance, but quality control of both hardware and processes going forward will be key.  They did reach orbit less than two years after their first attempt (it took longer for Falcon 1, about the same for Lockheed's Athena, but less for Electron and LauncherOne).

Great to see a launch from SLC 46 again.  Wish that place was busier.

Launching from Cape Canaveral Space Force Station costs @Astra about $1.5 million, says Astra's Tom Williams. Private spaceports are about one-third of that. #csf2022

I have no sympathy for these investors. They should've done their homework before of investing amount of money in Astra that justifies a lawsuit.

Same lawsuit originally announced the same day the Kerrisdale Capital short-seller report came out, and which Rosen elaborated on a couple of weeks ago. Although it does seem that five more law firms have signed on here -- perhaps that touches on edzieba's suggestion that this might be a coordinated one-two punch with Kerrisdale Capital?

Dunn with a couple updates on other launches:

• Planning CAPSTONE launch on Electron in late April, maybe pushing into May;
• Three Astra Rocket 3.3 launches (for TROPICS) still expected in late spring/early summer despite launch failure earlier this month.

New update from Astra on the failure:

Post-Launch Investigation: What We Found and Next Steps

Quote from: Astra
By Andrew Griggs, Senior Director, Mission Management & Assurance at Astra

Note: Astra has not yet finalized the LV0008 investigation results with the FAA. The information in this blog post is preliminary until the investigation has been fully closed.

On February 10, 2022, we launched Launch Vehicle 0008 (LV0008). This was our first launch with a deployable customer payload and our first time launching from Cape Canaveral. After a nominal first stage flight, an anomaly occurred during the stage separation process which resulted in the upper stage not reaching orbit and the end of the mission. We immediately initiated our investigation process to determine the root cause of the anomaly. Now, we can share more about what we’ve learned to date.

What Happened:
Our investigation verified that the payload fairing did not fully deploy prior to upper stage ignition due to an electrical issue. The separation mechanisms (our fairing has 5 of these) were fired in an incorrect order, which resulted in off-nominal movement of the fairing that caused an electrical disconnection. Due to the disconnection, the last separation mechanism never received its command to open, which prevented the fairing from separating completely before upper stage ignition.

Separately, we discovered a software issue that resulted in the upper stage engine being unable to use its Thrust Vector Control system. This led to the vehicle tumbling after the off-nominal stage separation, and caused the end of the mission.

What We Learned:
The root cause of the fairing separation issue was an error in an electrical harness engineering drawing. This harness was built and installed onto the vehicle exactly as specified by our procedures and the engineering drawing, but the drawing error led to two harness channels (pictured below at the locations ‘4’ and ‘5’) being swapped. Prior to the LV0008 flight, we had conducted an end-of-line signal test to verify the separation system and ensure that the system was wired correctly. This test would have been able to detect an error in the harness build or installation, but it was unable to detect an error in the design. The swapped separation channels caused a different deployment sequence than we expected, and this led to the failure to open the fairing. We’ve been able to recreate the failure mode by conducting several experiments at our factory with real flight hardware, one of the benefits of having an active production floor with several launch vehicles in various states of production at the same time.

After determining the root cause of the software issue, we found that our flight control software was vulnerable to a specific “packet loss” failure mode. A missed series of signals resulted in a chain of events, resulting in the upper stage’s inability to recover from its tumble. Although we had designed our software suite to be resilient to packet loss, an unlikely combination of factors caused a failure that we didn’t predict. We have been able to use our hardware-in-the-loop simulator to step through exactly what happened and diagnose the root cause with high confidence.

How We Fixed It:
Through the investigation process we had identified two problems that needed fixing: the harness issue and the software issue. Soon after discovering the harness drawing error, we fixed the drawing and incorporated the change on previously built harnesses. We also implemented a new end-of-line signal test that will allow us to identify this class of issue in the future, if it were to occur, prior to launch. On the software side, we’ve introduced a trio of upgrades designed to make our system even more resilient to packet loss and other similar failure modes. Through constant iteration and extensive testing, we have been able to demonstrate that the changes eliminate the failure mode we saw on LV0008, while making the software suite much more robust.

Here at Astra, iteration and learning are core parts of our culture. I’ve been continuously impressed with the speed, passion, and diligence that the team showed as they worked through these complex issues to identify exactly what occurred and determine the right path forward to resolve each problem. With the root causes identified and corrective measures in place, we’re preparing to return to the launch pad with LV0009 soon — stay tuned!



Astra has announced the results of the ELaNa 41 mission failure investigation. Two separate failures - an electrical issue with the fairing, and a software issue on the upper stage - caused the loss of mission.

Attiq: $ASTR's automated approach to production is already showing results, as the company has gone from building one rocket "every 6 to 8 months" to currently "building 1 a month, and next year our goal is to build one a week."



Attiq: Russia's Soyuz "was a workhorse" and $ASTR is going after opportunities where payloads no longer have a ride to orbit.

"We're talking" to customers about where Astra can fly satellites that expected to fly on Soyuz.
