It appears two of the three Raptors failed, just as with SN8.  I think it will be awhile before SN10 gets launched.  If SN8 was considered a "success," this test will have to go down as a "failure."   :shrug:

The FAA will keep this one locked down for a long time.

Elon Musk Vents Frustration Following Rocket Test Failure In Texas

Wccftech By Ramish Zafar 2/4/2021

https://wccftech.com/elon-musk-vents-frustration-following-rocket-test-failure-in-texas/

Quote
Space Exploration Technology Corp.'s (SpaceX) chief executive and engineer Mr. Elon Musk took to Twitter to vent out his frustration after his company failed to successfully land a prototype of its next-generation Starship crew and cargo launch vehicle platform on Tuesday. The failure resulted as one of the Starship prototype's Raptor full-flow staged-combustion methane-fuelled rocket engine failed to reignite as it attempted to land. As a result, the vehicle had insufficient thrust to counter the force of gravity, and as opposed to an earlier test, crashed in a tilted position.

Musk States SpaceX Engineers ''Too Dumb'' To Implement Solution For Preventing Starship SN9 From Crashing

The executive's comments came as a surprise as a handful of days back he had stated that he would be leaving Twitter for a while. This announcement came after Mr. Musk joined the conversation surrounding the meteoric rise of GameStop Corp.'s shares after a Reddit forum went against venture capitalists betting against the stock through short selling. He then went on to join popular trading application RobinHood's chief Vlad Tenev in a discussion around the entire affair on the audio-chat social networking application Clubhouse, where he questioned Mr. Tenev about why the latter's application had stopped trading for the stock as things heated up between the Redditors and the short-sellers.

Strangely, the host of Tweets that followed his announcement to leave were made from a Twitter web application. Musk generally posts through the platform's iPhone application and this discrepancy has caused some to question whether the messages are authentic, or if the executive's account has been compromised. Until now, even though he made other tweets that seemingly pushed cryptocurrency Dogecoin's price to new highs, the tweets are yet to be deleted; suggesting that it was indeed Musk who posted them.

Question: Why only light 2 engines for landing? Any engine failure means loss of vehicle, so you have two single points of failure. Why not light all 3, do the flip, then pick the best two and turn off the other?

SpaceX wants to launch its next Starship ASAP

Contrary to recent comments from CEO Elon Musk, SpaceX appears to be forging ahead at full speed in a bid to launch its next Starship ASAP.

Known as Starship serial number 10 (SN10), the prototype is the latest in a series of four ships SpaceX has ultimately set aside from low(er)-altitude development testing. Starship SN8 – the first functional prototype to reach its full height – debuted on December 8th, 2020, blowing expectations out of the water with a failure mere seconds before the end of a more than six-minute flight test. According to Musk, had a fuel tank remained properly pressurized from start to finish, SN8 could have very well stuck the landing on the first try.

They aren't hanging around with SN10. Potential Static Fire tomorrow, and that would mean a launch is possible in the coming day.

@BocaChicaGal
I have received an ‘Alert’ notice and there is a planned road closure between the hours of 9 a.m. and 6 p.m. tomorrow February 8, 2021. Starship SN10 testing campaign is starting.

Two months later, after the better part of two weeks of licensing and static fire test delays, Starship SN9 attempted to carry the torch forward but suffered an unrelated failure slightly earlier than SN8’s. One of two Raptor engines failed to ignite for a high-risk flip and landing burn, causing the Starship to impact the ground even more violently than its predecessor. It’s unclear why the ill-fated Raptor failed to ignite or why the engine that did ignite appeared to experience a major failure shortly thereafter but rocket propulsion is extraordinarily difficult – and Raptor is near – or at – the end of that scale.

While SpaceX obviously hasn’t spun around and fixed a complex Starship propulsion issue in a matter of days, Musk eventually revealed his opinion that he, his engineers, or some combination of both “were too dumb” to exploit one obvious way to mitigate the risk of engine failure during flip and landing. That ‘obvious’ tweak: reignite all three of Starship’s available landing engines, not just two.

Yeah there was speculation that lighting all 3 engines then cutting off one would tend to be a better idea.  Also, there was speculation that they'd flip to vertical a little higher to give them a bit more time.

They'll get it right here pretty quick...

SpaceX Starship prototype gets frosty for a launch attempt as early as this week

TESLARATI by Eric Ralph 2/8/2021

https://www.teslarati.com/spacex-starship-sn10-next-launch-flight-plan/

Quote
Update: It appears that SpaceX has completed Starship SN10’s first cryogenic proof test campaign and the company lifted its road closure around 4:30 pm CST, signifying the end of Monday’s testing.

If Monday’s cryo proof was successful, SpaceX has requested possible static fire test windows on Wednesday, Thursday, and Friday (Feb 10-12), though it’s possible another window could be added on Tuesday, February 9th. If Starship SN10 is able to complete a flawless wet dress rehearsal (WDR) and static fire on Tuesday or Wednesday, there is a chance – albeit small – that SpaceX can turn the rocket and pad around for a launch attempt on Friday.

Unfortunately, the FAA also deemed it necessary to reissue SpaceX’s airspace restrictions with a note that SN10’s launch is still “pending [authorization],” adding additional bureaucratic uncertainty on top of the technical hurdles the Starship still needs to navigate to be cleared for flight.

In the midst of what appears to be Starship SN10’s first cryogenic proof test, SpaceX has filed temporary flight restrictions (TFRs) with the FAA for a third Starship launch as early as this week.

An unleashed Jeff Bezos looks to shift space venture Blue Origin into hyperdrive

NBC News 2/8/2021

Blue Origin has fallen far behind SpaceX on orbital transportation, and lost out on billions of dollars’ worth of U.S. national security launch contracts.

Freed from his daily obligations at Amazon, Jeff Bezos is expected to turn up the heat on his space venture, Blue Origin, as it faces a pivotal year and fierce competition from Elon Musk’s SpaceX, industry sources said.

The 57-year-old Bezos, a lifelong space enthusiast and the world’s second-richest person behind Musk, said last week he is stepping down as chief executive of the e-commerce company as he looks to focus on personal projects.

Blue Origin has fallen far behind SpaceX on orbital transportation, and lost out to SpaceX and United Launch Alliance (ULA) on billions of dollars’ worth of U.S. national security launch contracts which begin in 2022. ULA is a joint venture of Boeing Co and Lockheed Martin Corp.

SpaceX’s Starship SN10 Is Officially Ready to Fly, But the FAA Might Slow It Down

Observer By Sissi Cao • 02/09/21

https://observer.com/2021/02/spacex-sn10-starship-launch-this-week-pending-faa/

Quote
It’s been less than a week since SpaceX’s SN9 Starship prototype took to the sky but crashed in the last second of its landing during a high-altitude test. Its successor, SN10, is already being prepared for another flight as soon as this week.

On Monday afternoon, SpaceX completed SN10’s first cryogenic-proof test with liquid nitrogen (to make sure the rocket can endure the temperature and pressure when filled with extreme cold propellants.) The next step will be one or multiple static fire test, which includes a “wet dress rehearsal” (filling the rocket with actual propellants) and firing the three Raptor engines at full thrust.

SpaceX has requested a static fire testing window on Wednesday, Thursday and Friday. There is also a test window on Tuesday. If SN10 passes static fire tests on Wednesday or Thursday and obtains the Federal Aviation Administration’s approval to fly, the rocket could lift off before the end of the week.

SpaceX reschedules Starship static fire amid deadly Texas cold snap, power grid failure

TESLARATI by Eric Ralph 2/19/2021

https://www.teslarati.com/spacex-starship-static-fire-reschedule-cold-snap/

After extreme weather and a once-in-a-decade cold snap ground SpaceX’s Starship launch preparations to a halt, the company’s next critical preflight test is back on the calendar.

SpaceX received permission to close Boca Chica Boulevard from 9 am to 6 pm CST (UTC-6) on Monday, February 22nd, with identical backup windows available on Tuesday and Wednesday. An agreement with Cameron County currently requires SpaceX to avoid road closures (and thus testing) on weekends – a compromise to preserve some level of access to Boca Chica’s public beaches for local residents.

Federal Aviation Administration Completes SpaceX Starship Investigation Clearing Path for Next Flight Test

TESMANIAN by Evelyn Arevalo February 20, 2021

SpaceX is working towards developing a Starship launch vehicle to enable humanity to colonize Mars. The aerospace company is testing prototypes of the spacecraft in a small beach village located in the southernmost tip of Texas along the border with Mexico. Multiple gigantic stainless steel Starship vehicles have performed flight tests above Boca Chica Beach. The most recent test was a high-altitude flight performed by a prototype called Starship SN9 (Serial Number 9). The vehicle lifted off approximately 10-kilometers-high above the sandy beach on February 2nd. Starship SN9 propelled with a trio of methane-fueled Raptor engines. SN9 took a similar flight path as its predecessor, the vehicle conducted an aerodynamic flight and landing flip maneuver. The flight lasted around six minutes as spectators along South Padre Island coast watched in awe. Starship SN9's flight was going well up to when the vehicle attempted a propulsive landing but one of its engines failed to relight upon descent causing SN9 to land at high speed, ending the test flight with a gigantic explosion.

It is not the first time SpaceX blows up a prototype, SN8 had the same fate. However, it is important to note the spacecraft is in its initial phase of development and explosions are expected. Each test offers engineers valuable data towards improving the launch vehicle. The explosion prompted Federal Aviation Administration (FAA) to investigate. Besides coordinating air traffic, the administration also conducts environmental and safety reviews to ensure safe spaceflight operations. “The FAA closed the investigation of the February 2 SpaceX Starship SN9 prototype mishap today, clearing the way for the SN10 test flight pending FAA approval of license updates,” the Administration said, according to journalist Jackie Wattles who shared via Twitter. “The FAA provided oversight of the SN9 mishap investigation conducted by SpaceX. The SN9 vehicle failed within the bounds of the FAA safety analysis. Its unsuccessful landing and explosion did not endanger the public or property,” they wrote.

The investigation completion clears path for SpaceX to launch the next Starship prototype – SN10 – at Boca Chica Beach (pictured above). Starship SN10 is expected to replicate SN8 and SN9’s flight path. The weather conditions in South Texas improved after the Arctic blast that caused freezing conditions in the area. Now, SpaceX will conduct a static-fire test of SN10’s Raptor engines sometime next week. According to Cameron County Boca Chica Beach road closure announcements, SpaceX could perform this crucial engine test as soon as Monday, February 22, from 9:00 a.m. to 6:00 p.m. Central Time. Back-up test opportunities are also scheduled for Tuesday and Wednesday at the same time. You can watch SpaceX operations Live in the video below, courtesy of LabPadre via YouTube.

I believe they still have more concrete to pour on the landing pad before SN10 (Bo) can be launched.  Then it will take time for the concrete to cure.  Two weeks maybe???

SpaceX Starship ready to find out if third time’s the charm later this week

TESLARATI by Eric Ralph 2/21/2021

https://www.teslarati.com/spacex-starship-sn10-third-times-the-charm/

Quote
After a miserable week of extreme cold, power grid failures, high winds, and general chaos, conditions are improving, the sun is shining, and SpaceX CEO Elon Musk believes there’s a “good chance” that Starship serial number 10 (SN10) could launch “this week!”

The third full-scale, full-height Starship completed by SpaceX since Starship SN8 rolled from factory to launch pad in October 2020, Starship SN10 is the second to last in a series of four similar prototypes built for the sole purpose of proving out an unprecedented method of landing rockets. On its December 8th debut, Starship SN8 – the first prototype to launch with a nose, flaps, three Raptor engines, and a high-altitude apogee target – made it far closer to total success than almost anyone expected.

Already installed on a second launch mount when Starship SN9 lifted off, SN10 is thus tasked with avoiding the ‘header tank’ pressurization issue that doomed SN8 and the Raptor reignition failure that doomed SN9. If SpaceX has rectified those two or three critical issues in the weeks since, SN10 arguably has the best chance yet of successfully touching down in one piece.

If SN10 fails to stick the landing, SpaceX has yet another Starship – SN11 – more or less complete and ready to roll to the launch pad to pick up wherever its predecessor leaves off. Due to the wholly unexpected degree to which Starship SN8 beat expectations, SpaceX appeared to scrap plans to build Starships SN12, 13, and 14 – quite literally in the case of SN12.

Prior to launch, Starship SN10 still needs to complete a healthy three-engine static fire test that was delayed from last week to no earlier than Monday, February 22nd. Backup windows are available on Tuesday and Wednesday. If Starship SN10 can fire up its Raptor engines without issue at some point in that three-day period, odds are good that SpaceX will be able to squeeze in at least one or two launch attempts before the weekend.

SpaceX Starship launch: SN10 could launch as early as Thursday after critical engine swap

Express By Sebastian Kettley 2/24/2021

https://www.express.co.uk/news/science/1401853/spacex-starship-launch-sn10-launch-tomorrow-static-engine-swap-evg

SPACEX could launch the Starship SN10 as early as Thursday, February 25, pending a critical engine replacement and second static fire test.

SpaceX's Starship prototype came to life yesterday, gushing out flames and smoke at the Boca Chica launchpad in South Texas. Static fire tests are the last hurdle - bar approval from the US Federal Aviation Administration (FAA) - SpaceX has to clear before Serial Number 10 (SN10) can launch on the company's third high-altitude test flight. And after two spectacular crashes so far, many fans are banking on the SN10 to ace its launch and landing attempt.

However, not all appears to have gone according to plan because Boca Chica's residents have been informed of more "space flight activities" today (February 24), suggesting another static fire test is on the table.

Mary tweeted: "I have received another 'Alert' notice for tomorrow and a road closure has been scheduled. Possible static fire test tomorrow?"

SpaceX chief Elon Musk then took to Twitter to confirm one of the rocket's engines needs to be replaced.

He tweeted: "One of the engines is suspect, so we're swapping it out."

The same issue haunted the Starship SN9 earlier in January.

Once the engine is replaced, SpaceX will need to conduct a second static fire test.

But once this test is out of the way, road closures around Boca Chica suggest Thursday is the earliest SN10 could launch.

Road closures have been scheduled around Boca Chica between 3pm and midnight GMT (9am and 6pm local time).

SpaceX rapidly builds, tests Starship Moon elevator for NASA

TESLARATI by Eric Ralph 2/24/2021

https://www.teslarati.com/spacex-starship-moon-elevator-nasa-prototype/

Quote
As part of a NASA program that will select one or two commercial crewed Moon landers, SpaceX is busy testing Starship and prototyping hardware and most recently built and demonstrated an elevator “in a very short period of time.”

Known as the Human Landing System (HLS) program, NASA selected three providers – a Blue Origin-led consortium, Dynetics, and SpaceX – to build prototypes and compete for one or two follow-on contracts back in April 2020. SpaceX’s Starship offering was deemed the riskiest solution and the company received a middling $135 million to Dynetics’ ~$250 million and the “National Team’s” ~$570 million.

For their ~$820 million investment, it’s unclear what exactly NASA has gotten from its two best-funded teams aside from paperwork, a few completed design reviews, and two low-fidelity mockups mostly made out of cardboard, foam, and wood. Meanwhile, in the ten months since SpaceX received its $135 million, the company has built no less than eight full-scale Starship prototypes, performed a dozen or more wet dress rehearsals and static fires with said prototypes, and performed two powered hops and two high-altitude test flights. Now, to add to that list of low-cost achievements, SpaceX has also built and tested a functioning prototype of the elevator Starship would use to lift and lower astronauts to and from the lunar surface.

SpaceX’s proposal is certainly a unique one, with Starship being no less than several times taller and heavier than both its prospective competitors. However, Blue Origin’s extraordinarily complex three-stage, four-component lander – requiring a separate transfer stage, descent stage, ascent stage, and crew cabin – makes even Starship seem somewhat reasonable.

Notably, that massive 8-10m (25-32 ft) stack of separate spacecraft – crew cabin at the peak – would force NASA astronauts to transit a several-story ladder to and from the lunar surface. Far taller than the Apollo Program’s lander ladder, which NASA was already somewhat tepid on at the time, navigating a tall ladder in a clumsy, imprecise lunar EVA spacesuit would be extremely challenging and relatively risky. Dynetics is by far the least concerning solution in that regard, requiring what amounts to a footstool relative to SpaceX and Blue Origin.

Blue Origin says maiden flight of its New Glenn rocket for U.S. Air Force delayed to late 2022

American Military News  by Caroline Glenn - Orlando Sentinel   March 01, 2021

https://americanmilitarynews.com/2021/03/blue-origin-says-maiden-flight-of-its-new-glenn-rocket-for-u-s-air-force-delayed-to-late-2022/

Quote
Blue Origin has postponed the maiden flight of its massive New Glenn rocket to the last quarter of 2022, after the company was snubbed for a lucrative contract with the Pentagon that went to rivals SpaceX and United Launch Alliance.

The rocket was set to make its debut later this year.

Blue Origin, the private rocket company owned by Amazon founder Jeff Bezos, has so far spent $2.5 billion on developing New Glenn, including building a factory on Cape Canaveral and refurbishing the launch pad where New Glenn will one day lift off from.

Bezos has said he sells about $1 billion in Amazon shares each year to fund Blue Origin.

Losing out on the contract reportedly cost Blue Origin $3 billion in revenue, Jarrett Jones, the company’s senior vice president for New Glenn, told SpaceNews. “That was a big hit for us,” Jones said.

SpaceX Starship SN10 high-altitude test flight slips to March 3

Spaceflight Insider by Nicholas D'Alessandro 2/1/2021

https://www.spaceflightinsider.com/organizations/space-exploration-technologies/spacex-starship-sn10-high-altitude-test-flight-slips-to-march-3/

Quote
The high-altitude test flight of Starship SN10 has slipped again, as is common with SpaceX’s highly-experimental test program.

The flight was expected to take place March 1, 2021, with Boca Chica Village residents getting the standard evacuation notice the previous night. However, within three hours of that notice the villagers had reported the evacuation was now canceled and the flight was expected to take place no earlier than Wednesday, March 3.

Associated temporary flight restrictions, known as TFRs, and road closures for the flight attempts on Monday and Tuesday were also canceled shortly thereafter, with new backup TFR windows being issued for March 4-6.

Monday’s weather is forecast to be inclement with an approaching cold front causing low visibility foggy conditions with a high chance of thunderstorms in the afternoon, a likely reason for the push to the right. With all previous pre-flight tests for Starship SN10 completed over the course of last week, including a 48-hour turnaround for a Raptor engine swap between static fires, all eyes will now remain on the weather as the major factor for when a launch will take place.

SpaceX gears up for Starship’s first triple-engine landing attempt

TESLARATI by Eric Ralph 3/2/2021

https://www.teslarati.com/spacex-next-starship-launch-triple-engine-landing

Quote
With FAA approval in hand, weather rapidly improving, and the latest rocket prototype seemingly rearing to go, the stars are aligning for SpaceX’s third high-altitude Starship launch and first triple-engine landing attempt.

As of March 1st, publicly-available FAA “temporary flight restrictions” (TFRs) and weather forecasts both agree that SpaceX is currently preparing to launch Starship serial number 10 (SN10) as early as Wednesday afternoon CST (UTC-6), March 3rd. Barring surprises, that gives SpaceX a healthy three-day period to account for any potential technical or weather-related delays.

Unlike its predecessors, SN10 will also debut a new triple-engine approach to landing, aiming to increase redundancy and boost the odds of a successful touchdown even if one of the Starship’s three Raptors fail during a last-second flip maneuver. Building on the failures of SN8 and SN9, it’s safe to say that SN10 has the best shot yet at sticking the landing.

•   Or did the Starship land a little way away from it?
•   Or was this caused due to hull damage?

2 Answers

It is probably due to a combination of factors. But the landing pad wasn't uneven and Starship didn't land away from it.

There were two main factors which contributed to the hard landing. Firstly the landing legs did not appear to deploy properly. Looking at close up images of the landing it is possible to see some of them swinging and not locking into position. So the ship landed unevenly to begin with.

But Elon Musk later confirmed via a tweet that there was an engine control problem of some sort: "Thrust was low despite being commanded high for reasons unknown at present, hence hard touchdown. We’ve never seen this before. Next time, min two engines all the way to the ground & restart engine 3 if engine 1 or 2 have issues."

Starship SN11 prepares for rollout as SpaceX plans for the future

NASA Spaceflight by Chris Bergin March 7, 2021

https://www.nasaspaceflight.com/2021/03/starship-sn11-rollout-spacex-plans-future/

Quote
Just days after SN10 completed the first – albeit hard – Starship prototype landing, SN11 is set to rollout to the launch site for its own attempt. Incremental progress is being made with the test flights, with another tweak to the landing sequence set to be implemented, based on data gained from SN10. Meanwhile, the first Super Heavy prototype continues stacking operations while parts for up to Starship SN20 are being staged at the Production Site.

These future vehicles are set to take up residence at a launch site SpaceX plans to expand, per updated documentation.

Starship SN10:

The clean-up of SN10 remains is continuing following what was a successful test flight.

Despite the Rapid Unplanned Disassembly (RUD) that occurred minutes after landing, SN10 achieved more milestones than her SN8 and SN9 sisters – both of which crashed into the pad and exploded.

SN10 mirrored the key objectives successfully undertaken by SN8 and SN9, including ascent profile, Raptor performance, and a stable return utilizing the aero surfaces. However, SN10 went a stage further, actually touching down on the landing pad in one piece.

This was, in part, thanks to the refined relight process for the Raptors, with three engines igniting ahead of the flip maneuver. This was a refinement to mitigate the issue suffered by SN9, which called for two Raptors to relight, only for one engine to fail, resulting in the vehicle being unable to complete the flip to vertical.

With all three Raptors lighting during SN10’s flip, the maneuver was completed. However, what was assumed to be immediate deselection of the one Raptor “with the least lever arm” wasn’t realized. All three Raptors remained on during the entire flip before two Raptors shut down quickly as SN10 came in for the vertical touchdown on a single engine.

SN10 appeared to be heading for a smooth landing. However, some of her landing legs did not lock into place during their deployment – which was assumed to be why the vehicle eventually exploded by coming down hard on her aft skirt resulting in tilt on the pad.

SpaceX Transports Starship SN11 To The Boca Chica Beach Launch Pad

TESMANIAN by  Evelyn Arevalo March 08, 2021

https://www.tesmanian.com/blogs/tesmanian-blog/sn11

Quote
SpaceX is rapidly developing the Starship launch vehicle at Boca Chica Beach in South Texas, which SpaceX founder Elon Musk calls ‘Starbase, TX.’ He envisions a fleet of at least one hundred shiny Starships embarking on voyages to the Moon, Mars, and beyond. Less than a week ago, on March 3, SpaceX launched the Starship SN10 prototype on a 10-kilometer flight test above the sandy beach. The stainless-steel vehicle propelled into the sky with a Raptor engine trio, performed an amazing aerodynamic flight and belly-flop maneuver upon landing. SN10 became the first full-scale Starship prototype to ace a propulsive landing. Even though the vehicle exploded around eight minutes after landing, it was a successful test that enables the company to move forward towards making launching Starship prototypes routine in South Texas.

This morning, SpaceX transported the next prototype that will perform a flight test to the Boca Chica Beach launch pad. Starship SN11 was rolled out of the high-bay at the assembly facility and transported to the nearby launch pad less than five miles down the road. Boca Chica residents captured video of the gigantic vehicle’s transportation operation, shown below. Starship is 150-feet-tall, equivalent to a 15-story-high building. The vehicle will one day be capable of transporting 100 passengers to space destinations.

To make a spacefaring future a reality, SpaceX runs around-the-clock operations to develop the spacecraft. Musk previously said the company could test at least twenty Starship prototypes before launching one to orbit. Starship SN11 is expected to undergo preflight testing at the launch pad in the days ahead. The first test will be a series of proof tests to assess if the vehicle can withstand the stresses it would experience in-flight. After it passes the proof tests, then SN11’s three Raptor engines will undergo preflight testing, including Wet Dress Rehearsals (WDR) and brief static-fire test(s) to assess the vehicle’s and engines’ performance. If that goes well, we could see another Starship take flight this month! You can watch SpaceX South Texas Launch Site operations Live 24/7 in the video below, courtesy of LabPadre via YouTube.

Why was the SpaceX Starship SN10 slanted when it landed?

That was so disheartening seeing it RUD after landing.  I could just envision flying for a month to Mars and making a perfect landing.  You are getting ready to disembark and BOOM.  Ughhhhh....

Hopefully they create some better landing legs.  It did appear that when they shut down the 2 engines to land that there was still some type of flame coming from the skirt area.  Maybe methane burning off?

Elon Musk Admits Mistake; SN11 Starship to Avoid Explosion Like SN10

Tech Times By Isaiah Alonzo 9 March 2021

Elon Musk just announced that the SN11 Starship is in the works and would make up for SN10's mistakes and explosion that recently occurred in the test flight of the Stainless Steel spacecraft in Boca Chica. Twitter fans have spotted that the SN11's landing parts were being installed, and here, Musk admitted his fault on the failed SN10 test.

It takes a lot for a regular person to admit his mistakes, and it takes more for a CEO of multiple companies to do this, with Elon Musk publicly sharing how his decisions may have led to the explosion of the SN10. Moreover, all that is lost and the company did not dwell much on its demise, focusing its sights on crafting the next Starship, the SN11.

 Here, Elon Musk (@elonmusk) said that the SN10 explosion was because of a low-thrust on its engine for taking in too much Helium which mixed with the fuel tank of the SN10, thus resulting in its demise. Musk said that the company is working on "multiple fixes" to improve the next Starship, getting it ready in time for its flight test.
SpaceX SN11 Test Flight: Not Making the Same Mistakes as SN10

Elon Musk said in another tweet that it was his fault as to why the SN10 had Helium on its fuel tank which mixed with CH4 or Methane, causing a reaction that turned the chemicals back to liquid. Musk said that it was intended to add the methane, as it is a safety precaution to avoid what happened to the SN8's initial explosion.

This is a tricky one given that I believe said helium pressurization was added to the CH4 header tank to mitigate what happened with SN8.

That's why it's a test program, of course.
Elon Musk
@elonmusk
Replying to @austinbarnard45
SN10 engine was low on thrust due (probably) to partial helium ingestion from fuel header tank. Impact of 10m/s crushed legs & part of skirt. Multiple fixes in work for SN11.
Elon Musk
@elonmusk
Fair point. If autogenous pressurization had been used, CH4 bubbles would most likely have reverted to liquid.

Helium in header was used to prevent ullage collapse from slosh, which happened in prior flight. My fault for approving. Sounded good at the time.

SpaceX Starship holds up under pressure, lines up Raptor engine test fire

TESLARATI By Eric Ralph 3/12/2021

https://www.teslarati.com/spacex-starship-sn11-pressure-tests-static-fire/

After a few false starts and some minor delays, SpaceX’s 11th Starship prototype (SN11) has made it through two of the three major tests standing between it and liftoff.

SpaceX rolled Starship SN11 from the factory to the launch pad on March 8th, just five days after Starship SN10 briefly became the first prototype of its kind to land in one piece. One or two issues with Raptor’s final landing burn caused SN10 to touch down faster than expected and eventually led to the rocket’s explosive demise around 15 minutes later. Still, the test flight was an almost unequivocal success and seemingly left SpaceX with more than enough confidence to speed through preparations for the next flight test.

Heading into the next day, SpaceX had hoped to kick off cryogenic proof testing but Starship SN11 required a bit more attention than expected and unknown bugs ultimately meant that only an ambient-temperature pressure test could be completed by the end of the test window. Those issues appeared to persist through the end of March 10th, preventing any kind of proof test attempt.

Starship SN11 is undeniably on a faster track than any of its three-engine predecessors and a clean static fire on Friday or Monday would leave a launch next week – SpaceX’s current target– well within reach.

Elon Musk reveals an early sign that SpaceX Starship SN10 was going to explode

CNET by Eric Mack 3/12/2021

https://www.cnet.com/news/elon-musk-reveals-why-spacex-starship-sn10-exploded-after-landing/

Quote
The prototype did more than just break a leg during its debut performance. There were other warning signs of a big finish.

A green flash as engines ignited for landing. A little too much speed. These were the early signs that SpaceX's SN10 rocket would join its predecessors in a rapid unscheduled disassembly, or RUD, as Elon Musk likes to call it.

On March 3, SpaceX finally appeared to make a soft landing of the latest prototype for its next-generation Starship rocket. But several minutes later, SN10, as the third prototype to make a high-altitude test flight was known, made an unplanned second flight after it exploded on the landing pad.

Elon Musk explained on Tuesday that the landing was actually a bit more crunchy than soft.

"Impact of 10 m/s (22 miles per hour) crushed legs & part of skirt," the SpaceX founder tweeted.

A close look at the landing of SN10 reveals it came in a little hot and fast. It even appeared to bounce slightly upon touching down.

Starship SN11's test flight is NET (no earlier than) Tuesday, per the latest Temporary Flight Restrictions.

This requires a fast turnaround time after a good static fire test on Monday. Probably unlikely to happen, but it's a NET.

Tuesday TFR 

Static fire on call for Monday.
Pretty breezy southerly surface winds Tuesday then shifting NE Wednesday bringing much clearer air for viewing. Nice weather for the remainder of the week so good chance Starship SN11 will fly!

They are sure having a lot of raptor issues.  Seems like they change out at least one (33%) on every vehicle.  Just think if they had 28 of them in there and having to change out 9....UGHHHHH.

Watching the static fire today it looked like just one engine lit and it was shut down in a matter of seconds.

I hope they can get these issues worked out.

Currently the Raptors are made in Hawthorne, sent to McGregor for testing and then sent to Boca Chica for installation.

Soon all of that will be performed in Boca Chica.

SpaceX Aims To Perform First Orbital Flight Test With Starship & Super Heavy Rocket This Summer

TESMANIAN by Evelyn Arevalo March 16, 2021

https://www.tesmanian.com/blogs/tesmanian-blog/super-heavy-booster-1

SpaceX is rapidly developing the Starship launch vehicle at Boca Chica Beach in South Texas. The company has an ambitious timeline to accomplish, they target to have a space-ready Starship by 2023. According to NASASpaceflight reporters, SpaceX aims to perform the first orbital flight test with the Starship Super Heavy duo this summer, they currently target July 1st. To conduct an orbital flight SpaceX will require a Super Heavy rocket booster, which the company has not tested yet.

The Super Heavy rocket booster will propel the Starship spacecraft to space and return to be reused. It will be fully reusable, capable of performing multiple flights per day. The company says Super Heavy will be the most powerful rocket ever developed, generating over 16 million pounds of thrust with 28 Raptor engines, more than twice the power of NASA's Saturn V rocket that launched the Apollo missions to the Moon. The Raptor is a full-flow staged combustion engine fueled by sub-cooled liquid methane (CH4) and liquid oxygen (LOX) propellants. To date, the aerospace company has test launched six Starship spacecraft prototypes, some have flown with three Raptors. SpaceX is working on the assembly of the first Super Heavy rocket booster prototype. Engineers started to manufacture a booster referred to as, booster number one, ‘BN1’, inside a giant high-bay at Boca Chica, pictured below. The vehicle will undergo a series of tests before SpaceX decides to launch a Super Heavy to space.

Right now, SpaceX is preparing Starship SN11 [serial number 11] to conduct a high-altitude flight test this month. NASASpaceflight says it obtained exclusive information that suggests SpaceX will skip testing/production of the next prototypes in the series ‘SN12, SN13, SN14’ and move on to advanced stages in Starship’s development. –“Following SN11’s flight, SpaceX will move on to SN15, 16, and 17, alongside testing with Super Heavy prototypes BN1 and BN2, before shooting for an orbital launch with SN20 and BN3,” NASASpaceflight reports. With less than three months until Summer, SpaceX is expected to increase its testing and iteration rate at Boca Chica, their goal is to perform the first test launch to space with Starship SN20 and Super Heavy BN3 by July. The first orbital launch mount is under construction already, pictured below. SpaceX founder Elon Musk said that Super Heavy will not land on the ground, the 230-feet-tall rocket will be ‘catched’ by a launch tower. “We’re going to try to catch the Super Heavy Booster with the launch tower arm, using the grid fins to take the load,” Musk said. We can expect to see the launch tower taking shape at Boca Chica in the months ahead. SpaceX envisions transforming the area into a '21st Century Spaceport' from where a Starship fleet will liftoff to the Moon and Mars one day.
