In "Packing for Mars: The Curious Science of Life in the Void," author Mary Roach recounts her experience applying to participate in a simulated Mars mission. After successfully navigating the initial selection process, she was informed that a representative from the European Space Agency would conduct a phone interview with her later that month. This opportunity excited her, highlighting the significance of research related to space travel and its challenges.

However, when the interview call arrived at 4:30 A.M., Roach's annoyance was evident, which she later recognized might have been a part of the assessment. This realization underscored the rigorous and often demanding nature of training for space exploration. The anecdote serves as a humorous yet insightful commentary on the psychological testing involved in preparing for the rigors of a potential mission to Mars.
