I think most of us "old heads" here are more patient with SpaceX's development method... in fact I for one am amazed by it. We remember what it took to get Redstone, Atlas and Titan II to any degree of reliability... lots and lots of booms and many at very low altitude. The track record of Falcon 9/Falcon Heavy speaks for itself. Starship will eventually equal their reliability. Great time to be a space junkie!!

Ok everyone, let's take a look at the whole picture. Elon/SpaceX does things a little different from the traditional. Remember Falcon, the first 3 totally failed. The 4th launch was successful and then Falcon makes history. Starship will be fully successful. Go SpaceX!!

[@torben777]

You are talking about falcon 1, which never made any history. Falcon 9 - that has made history - worked on first try.

[@johnnemeth6913]

@@torben777 Falcon 1 did make history. It was the first completely private rocket to successfully achieve orbit and paved the way for everything that came after.

[@torben777]

@@johnnemeth6913 I think that is a matter of definition and interpretation. Sure SpaceX is a private company, but so it ULA, Boeing, Lockheed Martin, Northrop Grumman etc., and NASA was an integral part of the Falcon 1 development, which they also largely financed, just as they have been on countless previous US rocket developments. Lockheed Martin developed the first Atlas rocket in 1957, which is 14 years before Elon was even born, and it flew humans to orbit in 1962. The contract type was slightly different for Falcon 1, with the private company taking a bigger part of the risk, but US rockets have always been build by private companies.

[@ralphwagenet852]

I think that the next launch will be a little while yet. SpaceX needs to figure out what went wrong, redesign whatever needs redesigning so that it doesn't happen again, retrofit the new design onto the existing booster and ship, run some tests to make sure that the redesigned parts work as intended, and tell the FAA that they've made the corrections. This will probably take a few months, so I'd say that some time in mid to late May is the earliest we can hope for for the next launch.

As I was watching the futile attempts by the grid fins to o stabilize the tumbling booster, I was immediately thinking about all the fuel slosh this must have caused. So it was no wonder to me that the booster didn‘t relight and then exploded - this was similar to the consequences of the sloshing in IFT-2 after hot staging!

[@fridaycaliforniaa236]

Actually, if the Starship was any other rocket, the fact it went to space, was able to open its door and to act like it dropped a payload in orbit, means that it would have been a successful flight. The problems encountered during the flight were only related to things and events tied to reusability

[@opioid01]

If it was any other rocket or any NASA project it would have been shutdown in a heartbeat. Remember according to schedule this rocket should have been ready for fuel transfer and reentry. ( Part of Artemis and moon base). It succeeded leaving earth only by the third attempt. And didn't even succeed completing spacex own checklist. The payload bay door got stuck, there was apparent loss of fuel in orbit which caused the tumble. Should have re-entered earth in the Pacific but only did so in many pieces. Spacex is so far behind schedule it's unbelievable congress keep supporting them. As of now the government has payed 3 billion dollars for three failures. Imagine if it happened to NASA!

[@spacegamer85]

I don't foresee the next launch of IFT4 before June 22nd not because of stage zero but to correct to cause of the tumble on Starship. Also the Pez dispenser door is going to get some upgrades as well - might even see a discharge of a few Starlink satellites (6) to test functionality. And there will be some modifications for the booster engine area to minimize plasma / shockwave damage. (imo)

[@rasul3d]

I was following all this online. That was breathtaking.

[@tomj819]

I think the booster's problem was hitting the tropopause too fast. At 7-6km when atmospheric density spikes the booster was doing mach 3+ and you could see the fins couldn't handle the instability and correct fast enough, resulting in fishtailing. That level of sloshing in the tanks could easily cause the engines to fail to relight. I think they may need to start the central 3 engines a few seconds earlier to decel and give some gimbled thrust correction before starting the suicide burn proper...

[@kstricl]

I was thinking same. Maybe even a single center at a much higher altitude, get the remaining fuel to settle.

[@LezChap]

But the Booster doesn't need to do a suicide burn...it can throttle thrust to the point where it can hover (for as long as the fuel/oxygen lasts). A suicide burn is when you have too much thrust and have to time it perfectly so you slow down enough to stop without lifting back off because the excessive thrust.

[@Whataboutit]

Wind that day could also be a problem. You can clearly see the oscilation problem of left and right roll starts right where it goes through that cloud layer. Sometimes those cloud layers form due to high wind share.

[@tomj819]

@@LezChap lol, sorry, force of habit. Either way, they proved they don't need a re-entry burn since their peak velocity never went above a Falcon's post-burn. Just need some tweaking at the end and they're home free!

[@AlJetdriver]

What is the difference between a Falcon 9 booster re-entry and the SuperHeavy booster re-entry regarding potential engine damage and engine relight?

[@sander915]

SuperHeavy is way bigger, and holds a lot more fuel which can cause fuel slosh. SuperHeavy also skips a re-entry burn, so it's going a lot faster when it does it's landing burn.

[@gdutfulkbhh7537]

Holds not enough fuel, it seems.@@sander915

[@tomj819]

For most of the flight Super Heavy is actually more robust, but its the critical tropopause threshold when atmospheric density spikes where it fell apart. Super Heavy has lower initial velocity in the upper atmosphere because Starship carries a hell of a lot more fuel than a Dragon does so can boost itself higher. SpaceX hoped that would allow them to skip a re-entry decel burn and they were kinda right, since at 50-40km the two had comparable velocities. That said, Super Heavy has a LOT more mass relative to its cross-section so by the time it hit real air resistance at 7km it was still over 1500kph which is almost double that of a Falcon 9. You can see it start to fishtail and the fins don't have the response speed to stabilize. That will cause fuel sloshing which could have caused the relight failures. I figure in future they'll light the central 3 engines a shade earlier at about 10km to get some decel and gimballed control to help the fins out, and start the other landing engines a bit later to compensate.

Excellent stuff bro

[@christopherayers4416]

I remember them having a problem re-lighting Raptors during the SN8 - SN15 days. They needed 2 engines burning to land, but when they tried to light just 2 there was no margin for error. The solution was to light em all and shut down what you don't need. I wonder if the same approach might work for SuperHeavy....

[@nic.h]

They were trying to light quite a few of them and very few showed signs of life. I think the grid fin issue likely also contributed to this by causing fuel to sloosh around.

Great coverage

Great job SpaceX

[@SimonAmazingClarke]

Booster - there was a lit of movement during the latter phase, this would have caused slish in the fuel tank exacerbating the movement of the booster. The Grid fins did a great job, but the flight computer software will need looking into.

[@kristofferpaulssonmisc2195]

About the booster reentry, it had first a free fall and reached a speed of 4000 kmp, then when it reached the lower atmosphere there was a natural breaking in to 1000 kmp, this is the right place to start ignition of some engine because of artificial gravity and no sloshing in the fuel tanks, later in the next free fall it was impossible to reignite the engines again

[@nickl5658]

Doesn't SpaceX do the slam dunk landing to safe fuel... ie it ignites its engines at the very last possible moment to stop its fall. Because the longer the rocket engines are on, the more fuel they use even if it is idling,

[@kristofferpaulssonmisc2195]

@@nickl5658 They can't ignite when the fuel is sloshing in free fall

The team at SpaceX is amazing! Can't wait to see what comes next 🎉

[@pekkoh75]

Well done SpaceX!

Congratulations Felix on 400k subs. The WAI community is growing at a crazy speed.

[@bberns35]

Great Work CONGRATULATIONS ON SUCCESS- looks Good ! Thanks for all the hard work!

[@thecool400]

Always informative Felix ThanX you Rock

[@baziwan9407]

Boots installed around the RCS thrusters could be a good way to prevent icing. General Aviation aircraft use them on their leading edges for deicing.

Thank you for a fantastic video.

[@MJ-tt9ww]

Thankyou Space X team and WAI! My 12yr old son and I follow these achievements and its an amazing connection point. We are in Australia so I let him stay up to 1 am on a school night to watch history in the making. It will be a lifelong memory for him and me.

They may take some more time to improve control of the Starship 29 to avoid the spinning and rolling seen on IFT-3 I think same flight profile as IFT-3 with successful de orbit burn the number one priority.
