Rename the “Deflecting” rule to “Proximity Alert”, and add:-

As a Knock-On Action, a Shuttle may Ram another Shuttle in the same Orbit. This causes the Rammed Shuttle’s Bay to gain 1 tonne of Debris.

In the rule “Local Maneuvering”, replace “select the result of one roll and increase their Orbit Number by that amount”

select the result of one roll, subtract from it the number of tonnes of Debris they have in their Bay and (if the result is greater than zero) increase their Orbit Number by that amount

To the rule “Orbital Dockyards”, add:-

If a Shuttle’s Orbit contains an Orbital Dockyard, that Shuttle may remove any amount of Debris from its own Bay.
