- onetwotree 10y agoThat's awfully euphemistic language for a huge fireball.
- gruez 10y agoWelcome to PR
- DVassallo 10y agoActually I thought this might be showing a glimpse of how SpaceX communicates internally. Saying "a huge fireball" is probably like saying "the website was down", but those responsible of keeping the website up would probably use more precise/euphemistic terms to describe why and how it broke. Ex: Elevated backend latencies caused the browser to time out waiting for a response. Yes, it's a softer description than "the site was down", but it's also more precise.
- haddr 10y agoDo I understand it correctly? "This was part of a standard pre-launch static fire to demonstrate the health of the vehicle prior to an eventual launch.". So they set some fire before the launch? Why?
- gliptic 10y ago"Static fire" = holding down the rocket and firing the engines for some time. It's a rehearsal of the whole launch procedure short of actually releasing the rocket.
- revelation 10y agoWhy do they still do that? I was under the impression that the rocket was held down for a second or so with the engines firing during the real launch, also.
- gizmo686 10y agoIt is. However the point of holding the rocket for a moment during the actual launch is to give the engines time to fire. The point of a static fire is to test the launch systems. The hope is that problems can be noticed before the actual launch, where they are more likely to cause catastrophic failure (and where we they might not be noticed in time to abort).
- zzalpha 10y agoThis "anomaly", as they're calling it, is why. Better to have the rocket explode on the pad in a controlled test than in the air over a populated area.
- haddr 10y agoThanks! I was quite puzzled, as they had this roadmap of having manned mission in like 2 years from now. Now as I learned that they do static fire shortly before lanching, and given that in this moment the astronauts should be already there in the rocket... I can't really imagine this.
- grkvlt 10y agono, the static fire is a day or so before the launch. in this case, the payload was integrated, and for a manned mission the dragon 2 capsule would be mated, but no crew/astronauts present yet.
- gtirloni 10y agoBest info I can find comes from /r/spacex: https://www.reddit.com/r/spacex/comments/4f9fxm/do_other_launch_providers_do_a_static_test_fire/ https://www.reddit.com/r/spacex/comments/4f9fxm/do_other_lau...
- Rebelgecko 10y agoI don't think anyone in that thread mentioned it, but Orbital has done static fires on the pad (sans payload).
- suyash 10y agoWhy don't they call it a catastrophe - hundereds of millions of dollars burned in this incident on Sep 1.
- ryanlol 10y agoThese things aren't catastrophes, they're inevitable and very much expected. Honestly, even "anomaly" might be a bit strong.
- bdcravens 10y ago"Catastrophe" is not a permissible word in Musketarianism.
- db48x 10y agoDid we watch different videos? I didn't see any money burning in the one I watched...
- ominous 10y agoTests are meant to be able to fail. We wouldn't hold tests if we didn't expect the subject to be able to fail. Not so much a "catastrophe", as "to be expected and previously accounted for".
