They should have set it up to land in the ocean, outside the environment.

TIL the ocean is outside the environment

I guess you haven’t gotten to see this video yet. Congratulations, it’s your lucky day.

[–] Kusimulkku@lemm.ee 5 points 10 months ago

Someone hasn't seen the video

It’s where sharks survive without fins.

All that orange smoke indicates it had hypergolic fuel onboard, which is toxic

[–] crapwittyname@lemm.ee 20 points 10 months ago* (last edited 10 months ago) (1 children)

It's not just toxic, it's incredibly toxic... the threshold for toxicity is below human sensitivity, i.e. if you can smell it, it's already too late. It's also flammable/explosive, poisonous, carcinogenic, catches fire without a spark, has no surface tension so it spreads faster than water, and it's generally the single most dangerous chemical known to man. In the words of Isaac Asimov:

anyone working with rocket fuels is outstandingly mad. I don't mean garden-variety crazy or a merely raving lunatic. I mean a record-shattering exponent of far-out insanity.

That's Hydrazine. The other liquid propellant, nitrogen tetroxide, which causes the signature red clouds, is slightly (!) less hazardous. It will still readily kill you. It's odd to see in the twitter photo that there was a fuming red cloud during takeoff, which suggests a problem with the burn ratios. Absolutely zero propellant should be allowed to pass unspent into the air, from engineering, safety and environmental perspectives.

IIRC Hydrazine is generally only used, or was used as the RCS thrust fuel for the Apollo program. You know, outside of the Earth’s atmosphere.

Pure hydrazine maybe, as that's not all that common. But the derivatives MMH and UDMH (which are both equally devastating to humans/the environment) are certainly used in the atmosphere, even by western nations. It's common as an orbit raising fuel.

They just don't care about their citizens.

[–] canis_majoris@lemmy.ca 4 points 10 months ago

Wow, they do not give a fuck.

At least the US has rules and regulations. Even shit like Starlink needs to have a designed re-entry or burn-up plan.

I can't imagine dropping fuel tanks over a populated area, or just not caring enough to redirect it in some way.

[–] VelvetStorm@lemmy.world 3 points 10 months ago (1 children)

Didn't see a video on the site.

Had to look for it as well, hit "See More" below the Twitter/Xitter post.
