**Aries (rocket)**
**Definition:**
The Aries rocket was an American sounding rocket developed in the 1950s for high-altitude research and atmospheric studies. It was designed to carry scientific instruments to suborbital altitudes.
## Overview
The Aries rocket was a single-stage, solid-fueled sounding rocket primarily used by the United States Air Force and NASA. It was derived from surplus military missile components, notably the first stage of the Honest John rocket, adapted for scientific payloads. The rocket was capable of reaching altitudes of approximately 200 kilometers, making it suitable for upper-atmosphere research and microgravity experiments.
## Design and Development
Developed during the early Cold War era, the Aries utilized a solid propellant motor, which provided reliable and cost-effective thrust. Its simple design allowed for rapid deployment and multiple launches. The rocket’s payload capacity was modest, typically accommodating instruments for atmospheric composition, solar radiation, and cosmic ray measurements.
## Operational History
Aries rockets were launched from various test sites, including White Sands Missile Range. They contributed valuable data to the understanding of the Earth’s upper atmosphere and space environment during the 1950s and 1960s. Although eventually superseded by more advanced sounding rockets, Aries played a significant role in early space research.
