Stealthy recon? *spoilers*

[Falcon0]

I've recieved a mission to do a stealth recon/meeting in an imperial system. But whenever I enter the system I recieve a message (withing a few seconds of entering) that the enemies have detected me.

I've equiped both my mothership and the only active fighter with a stealth system but they don't appear to be working at all.

Is the mission supposed to be a failiure?
