What was the ISS chasing last night?
Last night while partaking in an evening stroll along the lakefront, my partner and I noticed the ISS racing overhead, as it does on many evenings lately.
However, it was trailing behind a fainter object, travelling in the same direction, at the same relative velocity. We both watched this until it entered the Earth's shadow.
What were we watching? I have my suspicions, but it's Saturday, and this is the limit of my research... at least until I hit the bottom of the coffee cup...
