Assassination missions...

[CapuchinSeven]

It just run out of time and failed for me. Utter waste of my time.

I think you're doing it wrong, you don't scan USS's. You honk or use the nav beacon, that will give you an icon next to a planet on your left navigation panel.
Fly there, wait a few mins and then you get a "mission objective detected" sound and a blue USS will show up.

That's it. That's all you do.

It sounds like you're flying around, scanning random USS's.

I've done a bunch too, I went through all the steps. The mission listed the secondry star as the body he could be found at, so that's where I went. Nothing spawned.

Fly a full swoop around the planet, can take from 1 to 10 mins.

I've never had one fail on me, if one failed for you then... well it's rare... take a chill probe.

OK, you may have a point. Stars are a bit tricky. I suspect there is a particular bit of space you need to be at to find the mission USS, but with stars there is a lot of volume to travel.

However, you can often find the target in the system in supercruise during the time window.

Yeah that's why I was doing loop-dee-loops like a right twot for 2.5hrs until it failed.

I did a salvage mission last night, that worked exactly as described above.

Arrived in system and honked. Mission updated with relevant body I flew there and waited, mission specific USS appeared.

Not done an assasination mission in over a year.

There is a caveat to that. Last night I had to go to a kown/identified system. honking did sod all had to drop to hit the Nav point up which isn't mentioned in the mission details or messages.

....so that's where I went. Nothing spawned.

You throttled down to zero and waited how long?

Occasionally the target location will be a Star (either primary/secondary/tertiary) getting the USS's to spawn at that point can be tricky. If it's a planet then I have a 100% record of getting the Mission USS to spawn. If it's a star then that drops to around 25%. I'll give it 10 minutes. If nothing spawns then I'll just write it off as a bad mission and abandon.

I've had a similar experience: the target either interdicted me or a special blue USS spawned within minutes when I was next to the planet. Only once I could'nt get the target to spawn and the target body was a star.

Interesting. I have had 100% success rate, however, they have always been planets. Perhaps there is a bug when you are given a secondary star and the blue mission does not spawn.

Doesn't have to be the secondary star. The primary can also be assigned.

It's only ever if the star is assigned have I seen any issues. Planets have a 100% success rate (for me at least, and assuming I haven't found the target in SC before hand)
