SAGITTA PROGRAM INTRODUCTION

Sagitta in ancient Latin means arrow or lightning. Besides, the Sagitta constellation represents the mythical arrow, thrown by Hercules, which struck the Eagle eating Prometheus' liver.
The Sagitta rocket is our first step towards the sky. It is a scientific instrument to determine atmospheric parameters. Its system is devised to be completely reusable and reliable. Subsystems are designed to be cost-effective and redundant to prevent any malfunction from interfering with mission objectives: as an example, the parachute (a SkyAngle 44" provided by b2Rocketry) is operated by two redundant ejection devices.
Sagitta carries multiple sensors: environmental for atmospheric sounding and diagnostic for loads and attitude determination. Data is sent to the ground station through direct telemetry, while simultaneously being recorded on board for backup.

The propulsion is generated by a Promethevs V6 in one of its two variants, 350Ns or 550Ns.
An accurate design process helped us achieve both cost effectiveness and reduced weight: estimated mass at launch is between 3 and 3.5kg. Moreover, aerodynamic studies are at the base of fins and nose cone designs.

The following pages showcase in greater detail the different phases of Sagitta's developement.
