It's the mission where you have to blow up the Imperial Research Center, right ?
There is an easy way to do it:
Once the IRC's shields are out, press the comma key until your MFD reads "Hatch 100%" in the lower right corner. Find the hatch visually and blast it away. Now you have access to the inside of the station. Getting in will complicate things a bit, so your best bet is to save 1 missile, target the IRC's reactor, line up so you have a clear view of it and fire. The same can be done with lasers, you just have to get yourself exposed to anemy fire a little bit longer.
Oh...you'll find this thread in the player strategy section ...
