Parallax is an apparent displacement or difference of orientation of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.[1][2] The term is derived from the Greek παράλλαξις (parallaxis), meaning "alteration". Nearby objects have a larger parallax than more distant objects when observed from different positions, so parallax can be used to determine distances. In astronomy, parallax is the only direct method by which distances to objects (typically stars) beyond the Solar System can be measured.

I would like to know the OP's qualifications to make such assertions that these are spacecraft. Has he/she been to space and know exactly what is normal and what is not. Does he have information on how water and other such things would react in space. If not then he/she or anyone else without qualifications can make such assertions.
Unless you are an actual astronaaut, you are just making assumptions based on no personal experiences and therefore are just talking about things you know nothing of. I have never been to space, how many of you have been to space?
