What's falling off the vehicle at about 3:22-3:23? The large chunk of debris that you can see in silhouette against the flames.

It appears to be the Dragon, the actual space freighter that was going to deliver supplies to the international space station.

It would have been convenient if the capsule could deploy its parachutes for a safe recovery of the cargo.

[–]JacaByte 30ポイント31ポイント  (4子コメント)

At max-Q it would be ripped to pieces anyway, the only thing that would have saved the payload would be a launch abort, which I thought the Dragon capsule was capable of performing.

[–]SubmergedSublime 22ポイント23ポイント  (0子コメント)

That is Dragon 2, which is still in testing (as pointed out)

Dragon 1 has no form of active launch recovery.

[–]Sneakiecat 12ポイント13ポイント  (0子コメント)

They're still testing it. The pad abort test was a few weeks ago and the in-flight test won't happen for awhile.

[–]TheOutcast [スコア非表示]  (2子コメント)

Noob here. Why does it seem like (in the video) the rocket is coming facing downwards towards earth before explosion?

[–]proxpi [スコア非表示]  (0子コメント)

Space is actually really close to the surface... only about 62 miles above sea level. Most of a rocket's energy isn't dedicated to going high up, but to go fast enough around the earth to not fall back into it. The rocket is flying more or less sideways for most of it's flight, and it's just an illusion of the camera angle that makes it look like it's pointing downwards.

[–]ButterFingerzMCPE 221ポイント222ポイント  (23子コメント)

I feel really terrible now. I was following this college student on Instagram who had experiments on the rocket. He flew all the way from England to Cape Canaveral to see launch.

[–]this_sort_of_thing 98ポイント99ポイント  (1子コメント)

Yeah, anytime you see rocket/mission failures it's always sad when you think about all the work that's put in just eradicated like that. But I guess it's part of the line of work, always has been.

I'm sure everyone whose part of projects like this are aware that it can all go down the drain in an instant, but when it works it's amazing so people just try again.

[–]Leezoat 51ポイント52ポイント  (3子コメント)

Yeah, several of the students were crying at the end. It was pretty terrible.

[–]Bigred2989 [スコア非表示]  (2子コメント)

It's part of the job to see your experiments go up in smoke with things like this. Rocket failures are common enough to worry about them and to prepare contingencies.

[–]ccball954 [スコア非表示]  (1子コメント)

Which is what's crazy to me! I would think that they would put plenty of generous 'factors of safety' (so to speak) on every system of the rocket so that the chances of failure were extremely small. Obviously this isn't the case, as rocket failures are as you say common enough.

[–]Lorem_Ipsum 13ポイント14ポイント  (0子コメント)

There were some student payloads that were lost on the Orb-3 failure, rebuilt, and then flown on this CRS-7 that just failed.

As far as I know this is the first mission failure SpaceX has encountered since its first three test flights. They will learn from it and be ready to launch again next month.

[–]SkunkMonkey 272ポイント273ポイント  (89子コメント)

Everyone is so quick to forget all the failures of early government space programs. These things used to explode frequently, some never leaving the pad. The fact that SpaceX has experienced so few catastrophic failure so early on is a testament to what we learned from those failures.

[–]Coconut_Twister 153ポイント154ポイント  (39子コメント)

Correct. SpaceX had three failures before their first success. In contrast, NASA had close to 15 or 20 failures. SpaceX has the luxury of learning from Mercury, Gemini, and Apollo for their Falcon 9 design.

[–]SkunkMonkey 62ポイント63ポイント  (8子コメント)

And those failures were during testing. This is the first failure and loss of craft during launch. The other failure was a failure to make orbit but no destruction of craft during launch.

I'd say SpaceX is doing quite well on the shoulders of NASA.

[–]theasianpianist 69ポイント70ポイント  (6子コメント)

No, the first three failures for SpaceX were during actual launches (at least two of them were). Ashlee Vance's biography mentions that they lost government payloads on at least two of them (one USAF satellite and a bunch of experiments from NASA).

[–]zlsa [スコア非表示]  (0子コメント)

I think that NASA and the USAF treated those as tests of SpaceX rather than mission-critical payloads.

[–]SgtDirtyMike [スコア非表示]  (2子コメント)

While the 3 failures were actual launches, only the 3rd flight was a truly commercial/government venture. The first failure was carrying FalconSat, which was a satellite developed by Air Force Academy students. The second failure was carrying "DemoSat" was was presumably a test payload. The 3rd failure contained the most valuable payload - Trailblazer, PRESat, NanoSail-D and the remains of individuals that paid to have their ashes in space.

You have to remember that whenever a gov't or commercial entity launches a rocket into space, that vehicle will always be given a mission. Typically rocket launches are not just to test the vehicles themselves, but they also have a specific purpose. For example, NASA would never test it's Orion vehicle on a ballistic trajectory. They would either do an orbit around the moon via a translunar injection (similar to Apollo) or simply reach low-Earth-orbit.

[–]Coconut_Twister 1ポイント2ポイント  (0子コメント)

Ah that was it. I read her biography as well but couldn't quite remember the details. They were very much in testing, but if you're going to launch a rocket into orbit, might as well carry some kind of payload while you're at it.

[–]SkunkMonkey 4ポイント5ポイント  (0子コメント)

I stand corrected, my recollection on that was a tad fuzzy.

[–]reph 5ポイント6ポイント  (15子コメント)

However the Saturn V never went xplodey, despite using technology that's a half century older. These recent commercial designs are still less reliable than NASA's at its best.

[–]ch00f 13ポイント14ポイント  (2子コメント)

The Space Shuttle experienced two disasters that resulted in loss of life...

All three Apollo I astronauts were burned alive during a test.

Apollo 12 was struck by lightning twice and almost had to be aborted.

Skylab failed to extend its thermal shield and had to be repaired in orbit.

The Mars Climate Orbiter crashed because of unit conversion error.

The Hubble space telescope had a faulty lens that had to be repaired in orbit.

Gemini 8 had a failure that resulted in an uncontrolled spin of the craft that almost killed the crew.

Apollo 13 had some issues.

Hell, the upper stage of a SaturnV had a rapid unplanned disassembly while testing the launch escape tower.

Space is hard. Now just as it was then.

[–]Accujack [スコア非表示]  (0子コメント)

You're not even mentioning the multiple program failures at NASA that resulted in Billions of dollars spent for little gain. Canceled programs that were too ambitious, and cost overruns for programs that never fully reached their goals.

[–]Okryt 4ポイント5ポイント  (1子コメント)

It never exploded, no. But Apollo I was a disaster (all three crew burnt alive during a test) and Apollo 13 is so famous I shouldn't even need to mention it.

[–]EETrainee [スコア非表示]  (0子コメント)

Apollo I never used the Saturn V rocket though, nor went into space. Apollo 13's damage occured actually completely after all three of the Saturn V launch and transfer stages had been used and ejected (S-IVB, S-II and S-IC), so it's more of a payload system failure than a rocket failure like with SpaceX here.

[–]Schlagv 32ポイント33ポイント  (13子コメント)

SpaceX hired lots of NASA people. They only succeded so fast and so cheaply because they took some of the best people and started again without past compatibility.

Making such mistakes now is not something easy. They are not anymore the fun Silicon Valley kiddies playing at space. They are considered as a serious competitor.

When the first Ariane 5 rocket failed, it was a scandal. They had not a single failure ever since.

That kind of failure is very bad for SpaceX reputation.

[–]SkunkMonkey 24ポイント25ポイント  (11子コメント)

Rocketry will never be 100% safe, there will always remain some risk of failure. This is one reason Dragon has nine engines. In fact, one of their launches managed a success on 8 as one had failed so the designed redundancy worked like a champ. This failure occurred at Max-Q, the most dangerous part of the flight, so a failure here is not unexpected.

The Falcon/Dragon program is attempting to become man-rated, the Ariane 5 is not and, as far as I know, they are not attempting to make it man-rated. Also, IIRC the Ariane launches closer to the Equator making for much easier launches.

Anyone that takes this failure as a ding on the reputation of SpaceX is a fool. Failures happen, especially early in a space program.

[–]Rhaedas 4ポイント5ポイント  (8子コメント)

And notably, the first stage at this point seems to have not been at fault, but was performing perfectly. It was something in the second stage that failed. Doesn't downplay the failure today, but the Merlin design of the first stage has done well so far.

[–]SkunkMonkey 4ポイント5ポイント  (7子コメント)

Exactly. The rocket was going through Max-Q, the point where the stress on the craft is the highest. It seemed to me that something on the nose had caused it to no longer be quite so aerodynamic, there is like a small non-uniform vapor cloud on it just before it disassembles in an unplanned fashion. I'm guess that the front slowed down and the rockets just pushed the ass-end of it through the middle KSP style.

[–]Rhaedas 1ポイント2ポイント  (6子コメント)

So the front fell off?

sorry

[–]SkunkMonkey 2ポイント3ポイント  (5子コメント)

No, it's drag increased, potentially so much that the engines were able to push "through" the middle of the rocket which is where the the failure appears to have started the unplanned disassembly.

Part of that is because they are not flying nearly as much since shutting down the Shuttle program. =\

We're still flying astronauts to ISS at about the same pace as before, we're just being forced to pay the Russians for every ride since Congress wasn't smart enough to fund NASA fully. And honestly, while the Russian system has been reliable, the financial and government situation in the country does not give me much confidence. We need to get back on our feet and become self sufficient again, not only in sending astronauts to ISS, but to stop buying Russian engines for our rockets.

Well to be fair that happened decades ago.

I don't even remember the last time a NASA rocket and/or shuttle exploded after launch.

[–]quart_tanks 32ポイント33ポイント  (5子コメント)

Challenger exploded after launch in 1986, Columbia exploded on reentry in 2003.

[–]superpervert 5ポイント6ポイント  (4子コメント)

Columbia didn't exactly explode. It broke apart due to aerodynamic forces and heat stress when superheated air got inside the wing.

Challenger's fuel tank certainly exploded but again, it was aerodynamic forces that caused the loss of the craft, not the explosion itself.

I don't know why I feel the need to post this.

[–]mektel 16ポイント17ポイント  (3子コメント)

An O-ring that was too cold is not faulty aerodynamics.

[–]Calamity_Jesus 4ポイント5ポイント  (1子コメント)

Yup. Booster exploded taking the external fuel tank and orbiter with it. Cockpit had a hydraulic failure.. ie: it failed to keep the crew alive upon impacting the Atlantic ocean at terminal velocity. The current theory is that the crew was likely unconscious due to hypoxia (cabin pressure loss) very shortly after the breakup. They wore pressure suits in those days, but with their visors open. That rendered them useless for a sudden cabin loss coupled with high G force aerodynamic loads. These days the launch entry suits are more protective, bright orange (they were light blue), and the protocols keep them sealed during the entirety of launch.

[–]SkunkMonkey 12ポイント13ポイント  (0子コメント)

Yeah, well some of us were alive to remember many of these failures and have also looked into the history of rocketry. I vividly remember the loss of both shuttles.

They have done much better than NASA did in it's early days because they learned from those failures. This doesn't mean it will never happen again. Rocketry is inherently dangerous by virtue of trying to ride a controlled explosion into space. Sometimes that explosion will take control back.

[–]umilmi81 5ポイント6ポイント  (1子コメント)

Insurance doesn't gamble. They probably know the odds better than SpaceX. It's a huge corporation who's only business is knowing the odds of things.

Investors are also going to be ok. They aren't going to be happy, that's for sure, but investing is all about the best opportunity to get your money back. Losing spacecraft is part of SpaceX's estimations of profits and losses. As long as they don't lose significantly more spacecraft than they plan to then the bottom line still stays black.

[–]shodanx [スコア非表示]  (0子コメント)

There are no chance that this rocket had any sort of insurance.

[–]imnormal 0ポイント1ポイント  (3子コメント)

I'm confused. I thought it was the rocket that was on it's way down, to attempt a landing on the ship, that blew up? Is the Dragon Capsule still not ascending?

[–]Coconut_Twister 2ポイント3ポイント  (0子コメント)

That has happened twice. The primary objective in these launches is to send Dragon to the ISS. The secondary objective (during the same launch) is to land the main booster on a floating platform in the Atlantic after delivering Dragon to orbit. To date, they have made a number of successful launches to the ISS, and have made two attempts at landing. Both of those attempts. Resulted in vehicle loss. The first ran out of hydraulic fluid and loss control only meters above the platform. The second crashed after a valve opened too slowly and caused the craft to overcompensate and topple over after hitting the platform too hard. Today's launch was going to be a typical dragon delivery to low earth orbit, followed by the third attempt at landing at sea. However during ascent, an anomaly was detected in flight and the falcon 9 (including dragon and its payload) were lost at about the T+ 2:00 mark and 27000 feet.

[–]Roznak 0ポイント1ポイント  (0子コメント)

The rocket carried supplies to the ISS. It consisted of two stages. The first stage was to separate and return to a swimming platform after it had burned its fuel.

Rapid unplanned disassembly

[–]Seclorum 4ポイント5ポイント  (17子コメント)

Well actually it was a planned dissassembly, the Air force aborted it when the rocket went unstable.

They do this to protect populations downrange from where the rocket could concievably fly or crash.

[–]SgtDirtyMike [スコア非表示]  (11子コメント)

This is incorrect. The Air Force is not in control of the Space X vehicle. The vehicle is commanded at Space X mission control, under the supervision of NASA. The rocket did not self destruct. There was an overpressure in the upper stage of the vehicle. The liquid fuel tank likely began to depressurize and ignite rapidly, and the rocket disintegrated due to the fact that it was passing through the area of maximum dynamic pressure on the vehicle.

[–]TheYang [スコア非表示]  (0子コメント)

there are several people convinced that the first stage was intact until it self-destructed way after most of the first stage had disintegrated.
While I'm not as convinced as some, I do think the Videos available seem to show an Explosion of the First stage, during which the first stage seems to be still working mostly nominally, only significantly after this it's destroyed.

I'd bet the ISS is suffering a pretty fair kick as well. I was reading somewhere that the last 2 resupply missions in a row failed.

I can only find information about this explosion right now, so hopefully somebody can confirm / deny that for me. It would be pretty scary if they ended up in a situation with a low food-supply.

What sucks the most is that this rocket explosion will be played and replayed on cable news all day. If the launch had been a success, they wouldn't have uttered a single word about it.

Space travel has yielded a lot for humanity in terms of scientific and technological advances, but the vast majority of people only see it as "shooting missiles at rocks" and "a waste of money". Missteps and failures like the one today, coupled with the media's refusal or inability to give equal coverage to space travel's successes, reinforces the belief among many that NASA's funding should be gutted and that SpaceX is just a billionaire playing with expensive toys.

It's a truly unfortunate situation.

Do you have the launch costs for both programs by any chance? I keep reading this, but have never seen the actual numbers behind each.

[–]cecilkorik 3ポイント4ポイント  (0子コメント)

At least for Soyuz/Progress it's all done by conditional long term contracts and that makes it hard to get an exact per-launch number, as there are both variable and fixed costs to consider. The most recent estimate I heard was around $125-150 million for a manned Soyuz launch + recovery, and around $50 million for a progress resupply.

These are based on the prices they charge NASA, we don't know what their actual costs are.

Edit: from what limited numbers I can find, Falcon is also estimating $50 million for a resupply launch with Dragon. Remember that the Falcon/Dragon program is still fledgling, and they are still launching "traditional style" (disposable rocket) so those numbers seem quite reasonable and expected, and in fact pretty impressive that they can match Russian prices already even at this early stage.

Falcon, however, is intended to self-land and be re-usable in the long run. That will make a huge difference, and the majority of the per-launch cost will then be refurbishment costs on the existing Falcon launch vehicles. We don't know exactly what that will be, but certainly much less than $50 million would be the intention.

[–]clarkkent09 2ポイント3ポイント  (0子コメント)

My rocket wouldn't break up in space. OOOOOOOOOOOOOOO

[–]DirkMcDougal 8ポイント9ポイント  (2子コメント)

HUGE parties kicking off right now in Boeing, Airbus and Roscosmos. Suspect Boeing lobbying for CC downselect just got a shot in the arm.

Damnit.

Maybe in the board rooms and executive offices, engineers are still engineers and seeing other's really awesome work fail will always suck. Plus Boeing was sending up their new universal docking system, so they lost out here too.

I know some of those words.

Watching the live feed, the rocket appears to gradually go from vertical flight to lean over. Eventually the lean is so great that the video makes the rocket look like it has turned upside down. Can anyone explain why it looks like that when launching?

Also, the huge plume of fiery exhaust starts out looking like it is coming from the very end of the rocket, but as the turn over illusion happens, the entire back half of the rocket starts to appear as if it is inside the plume of flames. Is this also an optical illusion? Can anyone explain why it looks like this?

Rockets are supposed to turn during flight, else they just fly straight up and fall right back down. You need horizontal velocity along with all of that vertical velocity to achieve orbit.

[–]tccommentate 1ポイント2ポイント  (1子コメント)

Ah, this makes sense. And the height of the orbit is low enough that the tilting visibly happens as the rocket is climbing in sight of the ground. Thanks.

[–]mcesh 3ポイント4ポイント  (0子コメント)

Yep - the ISS orbit is only about 250 miles up, but it's doing more than 17,000 miles an hour!

[–]rw-blackbird 1ポイント2ポイント  (0子コメント)

Exactly. As much as I've tried to achieve orbit with a straight up vertical flight (as it's easier), thinking I'll just turn when I'm in space, it doesn't exactly work as planned and I accidentally turn my spacecraft into an ICBM with a payload of Kerbals. They'd need much more fuel and larger engines if they wanted to obtain orbit with a completely vertical ascent.

[–]DirkMcDougal 14ポイント15ポイント  (0子コメント)

Hard to tell if serious.

All rockets "lean over". Upward velocity is nearly irrelevant so long as you clear the atmosphere. Orbiting is essentially "falling" at such velocity that you match the curve of the earth. Without atmospheric drag you "fall" forever. That's orbit.

As for the plume it's normal for it to expand as atmospheric pressure drops. The failure was when all the white "clouds" appeared.

Armchair diagnosis from my POV was either FTS or second stage tank failure.

A good explanation of the reason rockets turn sideways: https://what-if.xkcd.com/58/

I live on the space coast. Saw the ship go up behind a cloud and didn't see it re-appear. Crazy stuff.

Space-X doesn't seem to be having much luck.

[–]totheredditmobile 63ポイント64ポイント  (13子コメント)

They've had amazing luck so far. This is their first total F9 failure in 19 flights, which is pretty good for a start-up company I'd say.

[–]RoswellSpaceman 6ポイント7ポイント  (1子コメント)

The problem is that the general public has heard very little about the other 18 flights. But they're going to hear a lot about this one, because cable news loves watching rockets go boom-boom.

And then we'll get to listen to inevitable calls from misinformed dolts to "stop shooting money into space and use it to create more jerbs here on planet Earth!"

It's so infuriating...

[–]jdepps113 3ポイント4ポイント  (0子コメント)

Don't blame cable news. EVERYONE loves watching rockets go boom-boom.

Well, not love, but we are all much more interested than we would be if it had worked properly.

Would I even be talking about this with you right now if the launch had gone well? Nope. And I learned about it right here on Reddit.

[–]maview 19ポイント20ポイント  (5子コメント)

Can we stop calling every new company a start-up?

[–]totheredditmobile 24ポイント25ポイント  (1子コメント)

Okay I'll rephrase. They're pretty good for a company that only started firing things into space 9 years ago.

[–]Silent_Ogion 9ポイント10ポイント  (0子コメント)

Which is a really, really good track record for rocket science.

[–]ASovietSpy 2ポイント3ポイント  (2子コメント)

He's probably referring to SpaceX trying to land it's first stage on a barge (Of Course I Still Love You) which they've tried and failed at twice now, this was supposed to be their third attempt but you generally need an intact first stage in order to attempt a landing.

[–]Saffs15 2ポイント3ポイント  (1子コメント)

Thing is, (and I know you're not really saying anything to the contrary) the landings were expected to be failures. So it's not actually bad luck even in those cases.

[–]ASovietSpy 3ポイント4ポイント  (0子コメント)

That's true, good point. I was really hoping they would get it this time though, kinda depressing.

[–]TheChad08 2ポイント3ポイント  (0子コメント)

I posted this as a response to another thread discussing failure rates.

1 failure in 19 attempts is a 5.26% failure rate. The space shuttles (designed in 1972) had an overall failure rate of 1.5% (2 failures in 135 missions).

[–]Trevo91 6ポイント7ポイント  (0子コメント)

Atleast they're trying though. You won't get anywhere if ya never even try

[–]izcenine[S] 5ポイント6ポイント  (1子コメント)

Not really. I woke up all excited this morning. I think I woke every living creature up in my house screaming "No"

[–]RizzMustbolt 0ポイント1ポイント  (3子コメント)

Only 30 more prototype failures before they match NASA's record.

[–]GET_ON_YOUR_HORSE 13ポイント14ポイント  (0子コメント)

Not really apples to apples considering SpaceX has so much history to learn from and advanced tools to use today.

[–]Black__Hippie 1ポイント2ポイント  (0子コメント)

Come on man. It's not like its rocket science or something.

I'm no expert on the matter but I suspect they didn't use enough strut connectors to hold everything together.

[–]Erik5858 0ポイント1ポイント  (3子コメント)

I live in Cape Canaveral and I didnt even see it in the sky but I could hear it rumble for a solid 5 minutes which I knew was abnormal. All the windows were shaking as if it was a earthquake.

[–]jdepps113 1ポイント2ポイント  (2子コメント)

Wow, man, that must be something to experience.

Wonder if the burned rocket fuel is bad for the air quality there.

[–]vorpalfox_werellama 1ポイント2ポイント  (0子コメント)

1 failed after 18 successful launches or 95% success so far. NASA, the government backed agency, had a 98% shuttle launch success rate. Not to put pressure on SpaceX, but they need to not miss another anytime soon.

I'm very glad that this was an unmanned operation.

Nontheless, it's a reminder that space exporation remains, to this day, the "most hazardous, and dangerous, and greatest adventure on which man has ever embarked."
