What role does telemetry play during a rocket's flight?

Telemetry plays a crucial role during a rocket's flight by providing real-time data about the rocket's performance. This data can include information on altitude, speed, acceleration, temperature, and other vital parameters that are essential for monitoring the flight. By transmitting this information back to the ground, engineers and operators can analyze the rocket's performance in real-time, making it possible to make informed decisions during flight operations.

This immediate access to performance data helps ensure the mission is on track and can provide insight into any potential issues that arise during the flight. Understanding how the rocket behaves in different phases of its journey is vital for both safety and mission success, making telemetry an essential aspect of modern rocketry.
