By outcome
- Proposed1
- Committed1
- Executed4
- Declined3
- Expired1
A declined burn is an outcome, not a failure — most conjunctions resolve on their own as the estimate tightens. An expired one is the failure: the window closed with the decision still open.
By burn axis
- in-track5
- cross-track3
- radial2
In-track burns dominate because along-track separation is the cheapest way to move a miss distance — a radial burn buys the same separation for considerably more propellant.
