Rocket used.
Configuration used.
First planned launch date.
Actual successful launch date.
Mission accomplished?
Number of scrubs.
Category/Reason for each scrub.
- Weather
- Technical
-- Rocket Problem
-- Payload Problem
-- Range Problem

Kinda looking for something like this question was asking for, I guess. But hopefully would like to find a general list that's kept relatively up to date (e.g.: within the past year or so at most).

Q: Most common causes of 21st century launch failures and how often do launches fail?

In this document (Page 7, point 4.3), Garrett Reisman notes that an analysis by Aerospace Corporation showed the most common causes for launch failures between 1980 and 1999. This document shows the top 3 causes as: Engine failure Stage-separation failure Avionics failure Given that there are...
