Japan's Space One rocket explodes seconds after liftoff
- svggrfgovgf 3y agoReally sorry to see that.

- harpiaharpyja 3y agoYes
- riffic 3y agoit's safe to say that.
- EspadaV9 3y agoI'd like to say, it's not very typical, the front doesn't normally fall off.
- bhawks 3y agoTime to pivot
- JKCalhoun 3y agoThere's a single frame where you can see the explosion appears to begin nearly right in the center of the rocket.
- WalterBright 3y agoSeems to me if you're filming a rocket launch, you'd want one of those very high frame rate cameras.
- MontagFTB 3y agoOther threads suggest it is the Flight Termination System being seen, so I am not sure it will help diagnose what’s happened.
- webwielder2 3y agoWhy are rockets always blowing up? Feels like we should be past the point of that being a regular occurrence.
- valianteffort 3y agoA lot of these companies are either trying different things or doing the same thing and no one is sharing their secret sauce. They are not insurmountable challenges but each team building rockets from scratch have to go through them. I think it's vital to the long-term success anyway. Easier to learn from your own mistakes than someone elses.
- _mlbt 3y agoThere's a really good reason why caricature of a highly intelligent individual is a rocket scientist. Engineering rockets that go where you want them to go safely is still a really hard problem!
- p1mrx 3y agoEh, how hard could it be? We're already in space, just need a bit less planet in the way.
- binoct 3y agoThe physics behind rockets requires the structure of the rocket to be extremely light, so structures can’t have more than an absolutely minimal safety factor. And the will experience extremely high vibration loads and g forces. And almost all the mass of the thing is extremely volatile fuel, which needs to be consumed at fantastically high rates and burned directly next to where it’s stored. Effectively, the margins have to be so small and thus to leave a much higher risk of failure than most other engineering problems, even when done completely correctly.
- dotnet00 3y agoAnd then there was the Superheavy booster comically tumbling around mostly intact for a comparatively long time despite the FTS having blown a hole in the tank (yes, I know that's an exceptional case).
- smcleod 3y agoone rocket, now many
- numpad0 3y agoVehicle is all solid 3-staged. Explosion ~5s into flight, right after immediate pitchover. Reportedly company explained that onboard auto FTS activated according to local media. Post-launch conference is/was currently planned 13:30 JST(0430 UTC). No more information for now. e: conference now re-scheduled to 14:00(0500 UTC), 3p live: https://www.youtube.com/watch?v=3F5dHsgBMMU https://www.youtube.com/watch?v=3F5dHsgBMMU
- WalterBright 3y ago> Vehicle is all solid 3-staged. I once embarked on an R&D program to make a 2-stage rocket out of bottle rockets. I'd tape the second engine under the first, and the first's fuse midway along the 2nd's fuse. Then light the lower engine's fuse. It was nothing but explosion after explosion, the top engine would never ignite, or sometimes fall to earth and then ignite. But being a Certified Rocket Scientist, I doggedly soldiered on. Finally, success!! The rocket rose up about 10 feet till the lower engine was exhausted, then the top engine ignited! Woo-hoo! It launched skyward another 10 feet before exploding. I was never able to duplicate that stupendous success. I bet Musk could have made it work reliably!
- qingcharles 3y agoEstes rocket motors always supported multi-staging. I made a ton of many-stage rockets as a kid. In fact, that was probably the biggest development -- how many ridiculous stages could I chain into one rocket? https://estesrockets.com/products/mongoose https://estesrockets.com/products/mongoose
- numpad0 3y agoupdate: Conference is now over. Not much technical statements than "FTS was activated ~5s, all debris/damages localized to company property, we're investigating". No immediate change of plans for flights 2 and 3 - first time asked the answer was worded like "we transport customer assets, missions are theirs", but the second one sounded like "no we're not paying out of pocket for an RTF dummy flight"(both my interpretation).

- zyang 3y agoI wonder participating in ISS was a mistake for Japan. It sucked up most of Japan's space program budget with very little to show for.
- watersb 3y agoTheir astronomers and engineers at NAOJ are wonderful. They built (and paid for) the Atacama Compact Array, which forms the center of the ALMA radio-telescope and is part of the Event Horizon Telescope. https://public.nrao.edu/telescopes/alma/ https://public.nrao.edu/telescopes/alma/
- medstrom 3y agoIsn't participating in ISS itself something to show? What does it mean to have something to show for?
- viknesh 3y agoGiven that the rocket blew up more or less at launch, it should be full of unspent fuel. How does one put out that fire? I'm guessing there's a lot of energy stored there, so letting it burn through doesn't seem wise.
- NortySpock 3y agoRunning shoes and knowing your escape route. That stuff is fuel and oxidizer mixed together. It is nearly impossible to stop once it gets started.
- perihelions 3y agoI think the only thing to do at that point is contain wildfires ignited by the burning propellant. The other commenter's entirely right: it's not practical to stop a combustion reaction where the fuel and oxidizer are already mixed. Here's a ground-level view from a similar solid-rocket failure, for some perspective: https://www.youtube.com/watch?v=mTmb3Cqb2qw https://www.youtube.com/watch?v=mTmb3Cqb2qw ("Delta II Launch Failure - Multiple Views - GPS IIR-1, 1997, Rocket Explosion, USAF, Canaveral LC-17")
