Hi Jimmy,

According to Wikipedia, all three stages of the Long March 2F rocket, which was the
model used on this launch, burn Dinitrogen tetroxide (N204) and Unsymmetrical dimethylhydrazine (UDMH).

See http://en.wikipedia.org/wiki/Long_March_2F

I love that they are referred to as 'strap on boosters'. Doesn't inspire confidence, but I love the look of the thing.

Yes, congratulations to the Chinese.

I have to say that the Long March rockets look like tin cans to me. LOL... The tapered boosters of the Russian's decades-old R7 looks like poetry in motion in comparison.

Now that they have the prototype build and bugs ironed out, I hear they are building 16 factories to mass produce them and drive the costs down so everyone can afford to have one. They want to get the cost per launch vehicle down to $100,000.

fuels and SI

Current use

Here are some common liquid fuel combinations in use today:
  • LOX and kerosene (RP-1). Used for the lower stages of the Soyuz boosters, and the first stage of the U.S. Saturn V, Atlas, and Falcon 9 boosters. Very similar to Robert Goddard's first rocket.
  • Nitrogen tetroxide (N2O4) and UDMH or MMH. Used in three first stages of the Russian Proton booster, most Chinese boosters, a number of military, orbital and deep space rockets, as this fuel combination is hypergolic and storable for long periods at reasonable temperatures and pressures.
  • hydrazine(N2H4) and Aerozine-50 are also used in deep space missions because they are storable and hypergolic, and can be used as a monopropellant with a catalyst.


Typical performances of common propellants Propellant mix Vacuum Isp (seconds) Effective exhaust velocity (m/s) liquid oxygen/
liquid hydrogen 455 4462 liquid oxygen/
kerosene (RP-1) 358 3510 nitrogen tetroxide/
hydrazine 344 3369

That's not smoke. It is steam from the water spray used in the noise suppression system boiling.
