I have several problems with these missions - some bug like and some fedback like.

So far I haven't managed to pass a single asteroid mission.

First and the biggest problem:
I have significant FPS drop when dealing with asteroids - it's very hard to try to align in position with newtonian physics, targeting the asteroids and shoot them when I get 15 or less FPS.
Outside asteroid mission the game run very well.

Next problem:
I can't target asteroids, nor do they are targeted by "best target" button.

- please make staroids targetable and selectable by "best target" button.

Third problem:
It's hard to prepare to this mission - it tells you which station will be thretened, but not from which direction asteroids will appear. This makes the problem that when mission start you have to burn to them, then deacelerate then align your speed and by then asteroids are like 2 km from the station and you took 1 out of 30 asteroids.

- It would be good that the closer asteroids get to the station the station control would update you with which asteroid are dangerous and which will not hit the station.
- it would be also good to highlight the location from which asteroids will enter the sector that way player would have more time to react and wouldn't have to burn-deacelerate (I have this in newtonian physics flight) but only accelerate and align with asteroids.
- also it would be nice if you could order your wingman to engage these asteroids.

Fourth problem:
Basic canons are useless against asteroids - so far I found that you have to upgrade corvette to heavy cannon to be able take out the asteroid, yet their fire rate is not so good when dealing with swarm od asteroids.

- maybe add some kind of dedicated anti-asteroid weapons?
