How is performance data typically collected during a rocket flight?

Performance data during a rocket flight is typically collected using onboard telemetry or ground-based tracking systems. This method is essential because it allows for real-time monitoring and recording of various critical flight parameters, such as altitude, speed, acceleration, and orientation. Onboard telemetry systems relay information back to ground stations, providing immediate insights into the rocket's performance as the flight progresses. Ground-based tracking systems further support this by incorporating radar or other tracking technologies to ensure accurate data regarding the rocket's trajectory.

The other methods of data collection are far less effective for comprehensive performance evaluation. Visual observation can provide some insights but lacks the precision and detailed information captured by technical systems. Paper logs for manual entry are impractical during active flights and prone to human error. Interviewing the launch team post-flight, while providing anecdotal insights, lacks the data granularity required for a thorough understanding of flight performance. Utilizing advanced telemetry and tracking ensures a structured and accurate collection of performance data essential for analysis and learning from each launch.
