VS-40

The VS-40 (Foguete Suborbital VS-40) is a Brazilian sounding rocket using solid fuel, stabilized aerodynamically, distributed between the first stage S40TM (4,200 kg) engine and the second stage S44M (810 kg) engine.[2][3] This configuration corresponds to the upper stages of the VLS-1 rocket.
