Green fuels blast off (a hydrazine replacement)
Nature ^ | 28AUG2013 | Alexandra Witze

Posted on 08/30/2013 2:22:21 AM PDT by Jack Hydrazine

Propellants offer satellites greater efficiency and lower toxicity than liquid hydrazine.

It looks like chardonnay, smells like glass cleaner and packs enough punch to shift a satellite. It is a Swedish-made ‘green propellant’, one that is fast becoming a viable fuel for manoeuvring craft in orbit. Along with a US-made propellant, it is providing an attractive alternative to hydrazine, the toxic chemical that has dominated this corner of the space industry for decades.

The Swedish propellant is currently nudging a satellite around in space, and may be used in a constellation of small commercial Earth-imaging satellites. The US-made fuel will take centre stage in a NASA test mission launching in 2015.

So does this mean you will be changing your name?

Absolutely not!!!

The Hydrazine family has so many members that the name isn’t going away for a long time.

Two things missing from the article. What it actually is and how much it costs.

It’s ‘green’, the cost doesn’t matter. /s

For comparison, the mission also carried hydrazine. It took 3 people 7 days to load the green propellant on the launch pad, and 5 people and 14 days to load the hydrazine.

What did they do? Load it with eyedroppers?

I suspect this is how any loading op goes... don’t know that for a fact though.

Add some, test for leaks (which takes a while), add some more... etc.

But I like your explanation, definitely funny :)

It’s extremely toxic stuff. You can breathe it in and die in very short order. Explodes in the presence of an oxidizer.

Look up the MSDS on it.

So it’s really my fault! Hydrazine causes AGW!

Will I be burned at the stake?

yes, i'm fully aware of that. Were YOU aware that during WWII the Germans fueled their ME 163 rocket planes with hydrazine in about 30 minutes?

I know they used T-Stoff (80% hydrogen peroxide along with some stabilizers) and C-Stoff (hydrazine and methanol) but delivered them in separate trucks because of how dangerous they were to each other, their corrosive nature, and toxicity.

I didn’t know it took 30 minutes but I can see why.
