Rigel (rocket)

Rigel is the designation for a family of small, solid-propellant sounding rockets developed by the Italian Space Agency (ASI) and operated by the San Marco Space Center. Primarily designed for atmospheric and microgravity research, the Rigel series consists of multiple variants tailored for different payload capacities and altitudes.

The Rigel program aimed to provide a cost-effective and flexible platform for scientific experiments in the upper atmosphere and near-space environment. These rockets are typically used for short-duration missions, carrying instruments and sensors to collect data on atmospheric conditions, cosmic radiation, and other phenomena. The data gathered from Rigel missions contributes to a better understanding of the Earth's atmosphere and the space environment.

Key features of the Rigel rocket family often include:

• Solid-Propellant Motors: Utilizing solid-propellant rocket motors for simplicity, reliability, and relatively low cost.
• Modular Design: A modular design that allows for customization and adaptation to specific mission requirements. Different stages or boosters can be added or removed to adjust the rocket's performance.
• Spin Stabilization: Spin stabilization is often employed to maintain stability during flight.
• Telemetry and Tracking: Equipped with telemetry systems for tracking the rocket's trajectory and transmitting data back to ground stations.

Rigel rockets are typically launched from the Luigi Broglio Space Center (formerly the San Marco Equatorial Range) in Malindi, Kenya. The location near the equator provides advantages for reaching certain orbits and conducting equatorial atmospheric research. The Rigel program represents a significant component of Italy's space research efforts, offering valuable opportunities for scientific advancement and technological development.
