[TOMT][MOVIE/TV][20th century] Male astronaut falls through ice on Europa and sees alien fish under the surface
I’m trying to identify an older sci-fi movie, TV movie, episode, or possibly a special that I saw years ago.
The scene I remember is set on Europa, Jupiter’s moon. A male astronaut or space explorer is on the icy surface, and somehow he falls through the ice or ends up seeing what is underneath the ice. Beneath the surface, there are alien fish / aquatic creatures / sea-life-like organisms.
I’m fairly sure it was from the 20th century, probably older than 2000. It is definitely not Europa Report (2013).
Things I have already checked or ruled out:
Europa Report — not it, too recent
2010: The Year We Make Contact — not it
Natural History of an Alien / Anatomy of an Alien — not it
I’m not completely sure whether it was live-action, animation, a TV episode, or a movie shown on TV. It may have been dubbed, edited, or broadcast as a “movie” where I saw it.
The strongest memory is: Europa + ice surface + male astronaut falling/breaking through ice + seeing alien fish or aquatic alien life underneath.
Does anyone know what this could be?
