I will have to correct several flawed statements in this thread:
1. You can find the stasis pod in a distress signal (plain distress signal to be exact, no ships or anything) in Engi, Rock, or Pirate sectors of any kind.
2. You can find the Zoltan scientists in any Engi or Zoltan sector on plain beacons.
However it is true that the warp gate is on a plain beacon in the Rock Homeworlds.
Edit: Also, it does not necessarily have to be in sectors 5, 6, and 7.
In fact, EVERY sector after the starting sector can easily be a Zoltan, Engi, Rock or Pirate sector. However Rock Homeworlds can only appear after sector 4. Or was that sector 5?
