Astroneer -When and Where? ( Last Mission )

This mission is to find a visitor and take a picture of my Astroneer character. I did not know what to do with it until space and time dimension that can be found in very short period of time after activating abandoned satellites in each planet. So even after I used probe ( 1 x steel ) to remaining vintage probes. I re visited the areas to see if I can find a visitor. On my case, I started off from Sylva, Desolo, Atrox, then to Vasania to meet a visitor. That&how I did my last mission of this game. Took me a while but I got lucky on 4th planet out of 7 existing in Astroneer.
