Yup, on my way to Mars for the first time :disco:
too bad I'm broke :violin: <-- can't even afford a full smiley band.. just the violin

If you get a TS, equip it with a ore collecter and mobile drilling system, go to kingdom end, there should be a nvidium asteroid [might not be big enough to scan] somewhere (you still have that egosoft forum link? there's a thread there about it), break it up until there are only rocks small enough to be retrieve with the ore collector, and then change ships, leave the TS at the site of the rocks, and leave the system. Order the TS to collect the nvidium, and it will keep collecting nvidium until it's cargo is full. (when you're not in system, a ship performing an ore collection order won't actually reduce the amount of available ore, like it would if you were inside the system) You can also do this trick with silicon or ore, but Nvidium generates greater profit. You could also find an nvidium rock somewhere else and perform the trick in another sector.
edit: Forgot one thing. Once the cargo hold is full, fly the ship to a shipyard and sell it.
