Argos Navis Aerospace

[TrevorMonty]

Company was founded by exRL employee and is based in Auckland NZ.
They make sounding  rockets, range of pressure feed engines and thrusters for upper stages and OTVs. With respectable 349ISP for larger engines.

They list MON-Propane as a propellant combination available for both their engines, which is certainly interesting. Should give better isp than peroxide-propane would, but worse than lox-propane. Oh, and is also very toxic, of course.

Those who are in the industry, how much of the trouble of handling problems of traditional hypergolic systems come from the hyrdrazine, and how much come from the MON/NTO?

Unfortunately, Argo Navis have gone bankrupt.  It's a pity, I knew some of the guys working there.
