As a player has submitted to another forum, they are running out of missions. So, I created one here:

Search for Eden
With you massive resources, skill, and fame, you can no doubt find the fabled Eden planet. Rumored to be a dyson of unfathomable resources, it will be a hard road, but you have what it takes. use what resources you have to construct temporary space probes and pay for mercinaries. Now go for it.

cost per mission includes 5000 dynite, 2500 Chrisium, 1000 Darrinyte, 500 Hydium, 250 Erixion, 100 Pawlacite, 50 Dieterion, 25 Dysillon, 10 Kurenite

requires high scan (for looking yourself), high number of hacks(for looking in enemy scans), high number of kills (to count as your fame), and high number of colonized planets (to base search parties and aquire more rumors)

I have also started a thread in the galaxy pub:

viewtopic.php?f=7&t=719

Well with that high a cost that Dyson better be a 40x Mega rich on all three resources that noone else knows about. Otherwise Im never doing that mission.

That is exactly what it is.

There already is a Dyson mission recently added I guess, but of different name/requirements

What I meant by "No one else knows about" I meant an unnocupied one that noone else can scan.
