Not Lost in Space, Just Wandering?
On the afternoon of Sunday, September 8, 2019, I was leisurely monitoring deep space when I noted an S-band signal that shouldn’t have been where it was if all was normal with the GEO belt world… GOES-15 presently lives at 128W and GOES-17 at 137W, so what was a GOES N,O,P series spacecraft doing in between them? A quick check of Space-Track.org data revealed it was GOES-13. But why was it here and drifting westward? As we will see GOES-13 isn’t lost, it’s just wandering.
