SpaceX – Launch Vehicle Failure

381 点作者 onwardly将近 10 年前
About 3 minutes in the vehicle appeared to explode. At the time it was ~15km downrange, going 1km&#x2F;s and around 35km up in the atmosphere.<p>UPDATE: Contingency press conference scheduled for 12:30pm EST- NASA TV said they wouldn&#x27;t have much to update before then.

Can anyone here with a little more knowledge answer the following please?<p>Who pays for the expense of these types of failures? Does SpaceX have some sort of 3rd party insurance from a private insurer or are they insured by NASA or another branch of the US gov?<p>How much is the equipment that got destroyed worth? If this happens multiple times in a short space of time as it seems to have recently does the cost of insurance go up for every launch? Does their analysis of data have any impact of the cost of insuring future launches?

I watched the launch live this morning. It reminded me of one of the best interviews ever. Elon Musk after SpaceX&#x27;s first three launches all exploded: <a href="http:&#x2F;&#x2F;archive.wired.com&#x2F;science&#x2F;space&#x2F;news&#x2F;2008&#x2F;08&#x2F;musk_qa" rel="nofollow">http:&#x2F;&#x2F;archive.wired.com&#x2F;science&#x2F;space&#x2F;news&#x2F;2008&#x2F;08&#x2F;musk_qa</a><p>I read that in high school, and it&#x27;s part of the reason I became an engineer.<p>&quot;Far better is it to dare mighty things, to win glorious triumphs, even though checkered by failure... than to rank with those poor spirits who neither enjoy nor suffer much, because they live in a gray twilight that knows not victory nor defeat.&quot; --Teddy Roosevelt

I feel bad for the SpaceX team. No sympathy for Musk considering all the mean spirited and unfair things he&#x27;s said publicly about Orbital Sciences&#x27; rockets (inc. &quot;One of our competitors, Orbital Sciences, has a contract to resupply the International Space Station, and their rocket honestly sounds like the punch line to a joke. It uses Russian rocket engines that were made in the &#x27;60s. I don’t mean their design is from the &#x27;60s -- I mean they start with engines that were literally made in the &#x27;60s and, like, packed away in Siberia somewhere.&quot;). Which is an even more ironic quote if you knew that Musk tried to buy exactly those same rockets from Russia and was declined[0].<p>Hopefully Musk is learning some humility.<p>[0] <a href="http:&#x2F;&#x2F;www.dailymail.co.uk&#x2F;sciencetech&#x2F;article-3082067&#x2F;Russian-space-bosses-SPAT-Elon-Musk-tried-buy-rocket-persuading-build-new-book-reveals.html" rel="nofollow">http:&#x2F;&#x2F;www.dailymail.co.uk&#x2F;sciencetech&#x2F;article-3082067&#x2F;Russi...</a>

Gods, it feels good to see the future finally arrive. It&#x27;s been a long time coming.<p>Growing up in the 80s, I became quite bitter about the pace of technological change. Sure, personal computers were <i>nifty</i>, but the heroic age of spaceflight was really what the future should&#x27;ve been about. That age had ended with Apollo 17, three years before I was born. Everything since then looked like a shambolic shuffle into a new dark age.<p>One insane coincidence in the late 80s gave me some remarkable perspective on this. I was taking the train down the coast of California, around the horn of Vandenberg Airforce Base. The train was the only place from which civilians could see the Vandenberg Launch Complex, including the SLC-6 Shuttle launch site[1]. Nasa had spent over $4 Billion preparing it for shuttle launches which would never come. The Challenger disaster had ended all hopes for that; the complex had been mothballed and was already starting to rust. Seeing this made my 13-year-old-self angry. I started ranting to the poor gentleman sitting next to me about how my grandmother hand grown up with horses and buggies yet got to see men walking on the moon; my generation, on the other hand, had seen nothing but decline.<p>As I ranted, the gentleman slumped in his seat. At the end of my rant, he gave a long sigh and said &quot;tell me about it.&quot; Then he introduced himself. He was Deke Slayton, a Mercury and Apollo astronaut[2]. He&#x27;d retired from NASA in 1982, frustrated with its bureaucracy, and tried to start a private space-launch company. It hadn&#x27;t gone well.[3] I wish I could say that our conversation gave me hope for the future, but it didn&#x27;t.<p>Later, my hopes were raised by the DC-X[4], then dashed by the subsequent (insanely corrupt) X-33 fiasco, and the failure of Beal Aerospace[5]. Raised again when I stood on the flight line at Mojave and watched SpaceShipOne take its first space shot[6], then dashed again when that program seemed to fly into molasses. Throughout, there was the sense that the future was <i>possible</i>, but by no means inevitable. There was no guarantee that it would arrive in my lifetime.<p>But now here it is. This time it&#x27;s real, this time it&#x27;ll work, and nobody will have to get nailed to anything. I couldn&#x27;t be happier!<p>1: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Vandenberg_AFB_Space_Launch_Complex_6#Space_Shuttle" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Vandenberg_AFB_Space_Launch_Co...</a><p>2: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Deke_Slayton" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Deke_Slayton</a><p>3: <a href="https:&#x2F;&#x2F;www.flickr.com&#x2F;photos&#x2F;stevefrancis&#x2F;sets&#x2F;72157629324639570&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.flickr.com&#x2F;photos&#x2F;stevefrancis&#x2F;sets&#x2F;721576293246...</a><p>4: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;McDonnell_Douglas_DC-X" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;McDonnell_Douglas_DC-X</a><p>5: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Beal_Aerospace" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Beal_Aerospace</a><p>6: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;SpaceShipOne_flight_15P" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;SpaceShipOne_flight_15P</a>

So in a case like this, would it be possible to have the pad abort system kick in? It could potentially pull the cargo module away and make an attempt to parachute it back for recovery? I doubt it could overcome the speed of the rocket but it might have a chance to separate it from the debris cloud?

I think (of course just an uneducated guess) things were going poorly from the beginning. It just looked slower than usual. Also, it looked like some of the engine exhaust was in places it should not have been several seconds before the &quot;anomaly&quot;.<p>I hope they get everything figured out and get back on track soon.

My only question is, is the real time telemetry at a high enough resolution that the exact cause of the explosion can be ferreted out? I&#x27;m guessing yes. This is another very important learning experience. One of countless thousands on the way to reliable space launch and recovery.<p>My only pessimistic thought in all this is that companies like Space X simply do not have the funds necessary to keep absorbing catastrophic loss and will just give up.

Bummer. Telemetry will be useful and of course. I doubt it will de-rail SpaceX.<p>Several interesting questions came to mind though, especially given the successful test of the Dragon 2&#x27;s thrusters, which is whether or not an inflight abort could have saved the cargo. I understand that isn&#x27;t practical in the general case but in the specific case of a Dragon cargo capsule, I&#x27;m wondering if they can fly one with the super draco thrusters. And have that one do the in flight abort sequence at some point in the future.<p>And given a rocket at mach 1+ what is the velocity of the explosion wavefront? In particular if you know that the back end of the rocket has just exploded, how many milliseconds do you have before the shockwave catches up to the front of the rocket? Could you perform a disconnect and burn of the super draco package to put the Dragon capsule far enough ahead of the shock wave to survive it?

A complete coincidence, I was just watching these worst rocket malfunctions [1] then flicked over to HN and this was #1 story.<p>Initial thoughts are that the main difference is now we have HD video and for some reason the controllers remain silent after the explosion... Why the silence? There used to be at least some reaction from the controllers.

Just wondering... Why don&#x27;t they use the new V2 Dragon with it&#x27;s escape&#x2F;abort system in all future resupply missions? At least they should be able to save the very expensive lab supply equipment, instruments, experiments, etc. Just fit it with the current V1 Dragon attach system for ISS docking.

AFAIK only three launch vehicles have better count of starts before the first big acident: Space Shuttle, Soyuz and Delta II.

Hate to see it also. It think things were going bad right from the beginning though (a completely uneducated guess).

Isn&#x27;t 180 seconds just the burn time of first stage? So it&#x27;s when 2nd stage should fire?

I feel very sad. This is second in a row. The guys up there are short on supplies...

Why don&#x27;t they eject the cargo as they&#x27;ve tested for crew?

Crazy how little actual conflagration there is. I would have expected a big fireball when that much RP-1 and LOX explodes. I mean the entire second stage&#x27;s fuel exploded.<p>Edit: Here&#x27;s a Titan 1, which was fueled with RP-1 and LOX exploding on the pad: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=UBzigaTSPZY" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=UBzigaTSPZY</a>
