The face of a frozen dead body suddenly appears directly in front of Dr. Stone as she and Kowalski are about to enter the space shuttle. The moment is sudden and unexpected, accompanied by intense music, and acts effectively as a jump scare. The dead woman does not wear a space suit, thus her skin has turned blue. Other bodies are floating in the background.
The sequences involving the destruction of the space stations are very intense.
A frozen dead body with a large hole right through his space helmet and head is seen in graphic detail, though without blood (or anything really) in the cranium, so despite it being potentially very intense under normal Earthly circumstances, is much less scary and disturbing than would normally be.
