Eighteen people have died in space. This includes four USSR, one Israeli, and thirteen USA citizens.

The review of historical records and web sources shows varying details on the number of space-related fatalities. Evidence indicates discrepancies in the claim that eighteen individuals died in space. For example, Ilan Ramon, who is often discussed, died during re-entry rather than in space. The recorded deaths of Soviet cosmonauts total three. Additionally, most fatalities occurred in incidents linked to space missions, but not necessarily in space, such as during takeoff or re-entry. The claims require nuanced interpretation regarding what constitutes a "death in space."
