During deep space flights, the crew must effectively make independent clinical decisions[4]. These decisions take place under conditions of delayed communication and uncertainty[4]. The crew is dependent on self-sufficiency due to limited access to advanced medical assistance[4]. Medical preparedness involves overcoming communication delays that prevent immediate consultation with Earth[4]. The article emphasizes the necessity of self-sufficiency in diagnosis and treatment during long missions[4]. These challenges are crucial for planned expeditions to the Moon and Mars[4].
