Impacting mining is a skill that allows you to mine asteroids for consumables, using your ships weapons.
To start impact mining, first orbit an asteroid field and then open the engineering window and select impact mining.
You will see asteroid listed you can impact mine, and to begin mining them select their name. Impact Mining involves slowly and methodically using your ships weapons to destroy areas of an asteroid to expose consumables to space, so that they can be recovered. Every time you remove an area there is a chance collateral damage will occur that might destroy whole sections of the asteroid by mistake (including consumables). The consumables available (if any) are listed and their location present on the grid.
Areas you can fire at will have a target icon and be labelled to indicate the grid block can be mined. Grid blocks with consumables present will have a gold target icon and labelled with the consumable quantity and name. To get to the consumables you must create a path so that the consumable grid block has destroyed blocks (exposed to space) adjacent to them.
The asteroids and the consumables within to do replenish so you will only get one chance to retrieve the consumables. You will need to find new sites for impact mining, which are also listed in the impact mining section.
A higher impact mining skill will reduce the change of collateral damage.
