My colony slowly continues to grow. Unfortunately luck is still evading me and I have not found anymore planets. My explorations take longer and longer as I have to travel further to explore the universe. I continue to upgrade my skills and send out explorers to try and find another planet, soon there will be emptiness all around me. Good news is there have not been anymore hostile attacks against me and I was able to acquire a Transporter 3 blueprint from the game developers :). It will come in handy when moving resources around in the future.
Good luck explorers! :)
