This looks like a craft behind the ISS speeding off into the distance. NASA must have been on their coffee break.
There is no place other than space that aliens want to see humanity…at their finest, reaching for the stars. This UFO is seen on the other side of the solar panels in the far distance. It look like is about the size of city bus and is disk shaped. A great catch by Streetcap1 of Youtube.
Many say its impossible to catch a UFO at the space station, however those people never put more than 5 minutes into looking. If you search for about 1-2 hours. I guarantee you will see a UFO.
