The footage was reportedly captured from NASA's ISS live cam feed and shows two small objects rising out from behind the Earth's horizon. NASA then cuts the live feed almost immediately afterwards, either to change the camera or because of a loss of signal between the ISS and Earth.
It's hard to think of a more suspicious set of events to have taken place: Mysterious objects appear, NASA cuts the live feed almost straight after.
There are however a number of possibly quite straightforward explanations. Both objects are moving in a trajectory that suggest they could quite easily be satellites. As was explained in Huffington Post article.
