Launch Vehicle Reliability Index

Overview

This pillar analyzes the historical track record and reliability of a specific launch vehicle model. It provides a data-driven probability of success for upcoming space missions, crucial for tech and science prediction markets.

What It Does

The index aggregates all historical launch data for a specific vehicle configuration, like the Falcon 9 Block 5 or Ariane 5. It calculates a baseline success rate, then adjusts it based on recent performance trends, such as consecutive successes or failures. The model also incorporates data from critical pre-flight tests to refine the final reliability score.

Why It Matters

It cuts through company hype and marketing by focusing purely on the hardware's demonstrated performance. This provides a quantitative edge in predicting launch outcomes, which are often high-stakes, binary events with significant market impact.

How It Works

First, the specific launch vehicle and its exact configuration are identified. Then, a comprehensive history of its previous flights is compiled, categorizing each as a success, partial failure, or total failure. A weighted reliability score is calculated from this data, and finally, this score is adjusted using information from recent ground tests and anomaly reports.

Methodology

A baseline reliability score is calculated using a Bayesian average, weighting the last 15 launches more heavily to reflect current operational maturity. The core formula is (Total Successes + α) / (Total Launches + α + β), where α and β are priors based on the vehicle class. A final modifier between -15% and +5% is applied based on static fire test results and any reported pre-flight anomalies within 72 hours of launch.

Edge & Advantage

This pillar offers a specific, hardware-focused probability, ignoring brand reputation and focusing solely on the vehicle's demonstrated ability to perform its mission.

Key Indicators

• Historical Success Rate

  high

  The overall success to failure ratio for a specific vehicle variant over its entire lifetime.

• Consecutive Success Streak

  high

  The number of successful launches since the last partial or total failure, indicating current maturity.

• Pre-Flight Test Results

  medium

  Outcome of key ground tests like static fires and wet dress rehearsals prior to launch.

• Time Since Last Anomaly

  low

  The operational gap since the last in-flight or ground test anomaly, showing if issues are resolved.
