* design & add metadata that specifies the amount of differences caused
during compression. For scientific use lossy compression is otherwise
difficult. (also research first if existing solutions exist and
implementg / use them if so)
* Write code that when feeded with several images (which may be taken
by a space probe from its surroundings) reliably calculates
its position. And additionally identifies objects that are not its
(and make sure we dont reimplement existing free solutions here)
* Better error concealment and maybe FEC for low latency space
