Reliability estimate for Falcon 9 landing
How likely is it that a Falcon 9 flight will land successfully?Using the same methodology that Ed Kyle uses at Space Launch Report, I ran some numbers to determine how reliable Falcon 9 landings are. That is, if (prior to launch), we know that a landing will be attempted, how likely is it that the landing will succeed? The short answer is that we should expect 92% of landings to succeed, and that estimate lies in a 95% confidence interval of 84%-98%. Read on for the methodology.First, I'm considering only Block 5 launches for this estimate. We have 62 attempted landings with 4 failures (B1050.1, B1056.4, B1048.5 and B1059.6). Falcon Heavy launches are excluded, as are the deliberately expended F9 launches (B1054, B1047.3 and B1046.4). Following the methodology in Lewis and Sauro, x/n is 0.94, which requires use of the Laplace estimate: (x+1) / (n+2). That gives us our 0.92 estimate mentioned above. I also calculate the Adjusted Wald Confidence Interval, which has a midpoint around 0.91 (but see paper above for why the midpoint of the confidence interval is a worse estimate than the Laplace method).I also ran the numbers for pre-Block 5 landings. Again, I excluded intentionally-expended boosters and Falcon Heavy launches. I also excluded boosters manufactured prior to the 'Full Thrust' model. That includes the first successful landing (flight 20), but excludes the failure of flight 21, as that was a v1.1 booster. Maybe that's not fair; it was a landing leg failure, not an engine failure that doomed B1017.Under the above rules, Falcon 9 landed 22 of 24 attempts. That works out to an 88% chance of successful landing when attempted, with a 95% confidence interval between 73% and 99% (smaller sample size leads to larger error bars).At this point in time, Block 5 appears to have a significant increase in landing reliability over previous booster versions. It has dipped; after losing B1048.5, the reliability decreased to 85% (0.68-0.96), but the long streak of successes afterwards brought the average back up. What none of this statistical analysis can capture is that SpaceX are now trying to recover boosters under more challenging conditions than before. B1059.6 was lost due to wear. Other boosters have successfully landed in conditions that would have been too challenging in the past. JRTI has more powerful thrusters that let it keep station more effectively. Octograbber allows the booster to be secured to the deck in weather that doesn't let humans get close.One crazy statistic to finish this up ... due to the sheer number of landing attempts, it is statistically more likely that a Falcon 9 will land (92%) than an Antares 2xx will successfully launch (91%), even though it has a spotless record with 9 successes in 9 launches. There just isn't enough data on Antares 2xx launches to give it a higher likelihood of success. See Ed Kyle's web page above for his launch reliability statistics for any number of other rockets (eg Vega at 88%)
