Add a new Dynastic Rule to the Ruleset.  Call it “Deflecting” and give it the following text:

As a Knock-On Action, a Shuttle can Deflect another Shuttle in the same orbit.  They decrease the other Shuttle’s Orbit Number by 1 and increase their own Orbit Number by 1.  They may then take a bonus Knock-On Action.  If they do, they must skip any further Knock-On Actions that the bonus Knock-On Action would permit.

In the rule “Navigation” remove the text

Orbits with the same Moon are equivalent modulo the Moon’s Orbital Size; that is, if an Orbit would have an Orbit Number larger than its Moon’s Orbital Size, instead divide its Orbit Number by the Orbital Size and set the Orbital Number to the remainder, or to the Orbital Size if the remainder is 0.

Then add the following text to the end of the rule:

Orbits with the same Moon are equivalent modulo the Moon’s Orbital Size; that is, if an Orbit would have an Orbit Number larger than its Moon’s Orbital Size or less than 1, instead divide its Orbit Number by the Orbital Size and set the Orbital Number to the remainder, or to the Orbital Size if the remainder is 0.
