TheVS-40 (Foguete Suborbital VS-40) is a Braziliansounding rocket usingsolid fuel and stabilized aerodynamically.
The original version, VS-40, uses the S-40TM (4,200 kg) first stage engine and the S-44M (810 kg) second stage engine.[2][3][4] This configuration corresponds to the upper stages of theVLS-1 rocket.[5]
VersionVS-40M used a S-40M engine for the first stage.[4]
VS40 performed the following flights:[4][6][7][8][9][10][1][11]
| Date | Version | Flight | Site | Mission |
|---|---|---|---|---|
| 1993/04/02 | VS-40 | V01 | Alcântara | Operação Santa Maria - Qualifying flight for the S44 engine. 760 seconds in micro-gravity.[4] |
| 1998/03/21 | VS-40 | V02 | Alcântara | Operação Livramento - VAP-1 (Fokker) payload.[12] |
| 2012/06/22 | VS-40M | V03 | Andøya | SHEFEX (Sharp Edge Flight Experiment) II payload.[9][10] |
| 2015/11/13 | VS-40M | Alcântara | Operação São Lourenço -SARA Suborbital 1 (reentry experiment) – Failure (exploded on pad)[6][7][8][1][12] |
A flight of VS-40M carrying "SARA Suborbital 2" was planned but eventually cancelled. A future flight of VS-40M carryingHIFiRE 8 is in development.[4]
The S-40 is a solid-propellant rocket motor developed and manufactured byAvibras Aeroespacial, a Brazilian aerospace company, primarily for use in sounding rockets. Different versions were used on several rockets:[4]

The S-44 is a solid-propellant rocket motor developed by theInstituto de Aeronáutica e Espaço (IAE), part of Brazil’sDepartamento de Ciência e Tecnologia Aeroespacial (DCTA).[14] It was used as second stage of VS-40 and VS-40M; the third stage of VLM and the fourth stage of VLS-1.[4]
