Malfunctioning Machines
• Several disasters accompanied rapid and exciting development of space technology
• Apollo 1 – electrical spark, 1967 • Space Shuttle Challenger (Video) –
upon launch, 1986• Columbia – disintegrated in
atmosphere (material failure), 2003

Role of man vs. role of machines
• In past, man was just a In past, man was just a mere passive observer mere passive observer
•Progressed so that man & Progressed so that man & machine shared machine shared complimentary relationshipcomplimentary relationship
•Yet, man not offered many Yet, man not offered many degrees of freedomdegrees of freedom

Psychiatric Morbidity
• Spaceflight is hazardous to man’s psyche
• Antarctic space-analog simulation program had startling results
• Participants experienced mood, adjustment, sleep, & personality disorders
• Anxiety/state of discomfort highly correlates with performance!

Antarctic Space-Analog Results• 12.1% of participants had symptoms
that met DSM-IV criteria• 31.6% - mood & adjustment disorders• 21% - sleep related disorders• 10.5% - substance related disorders• 7.9% - personality disorders
• Results suggest psychological factors should not be neglected

TrainingTraining
• Training should provide technical Training should provide technical mastery of the machine and a mastery of the machine and a remedy to space anxietyremedy to space anxiety
• Simulation is main form of Simulation is main form of trainingtraining
• However, the only advances However, the only advances made on simulators have been made on simulators have been electrical & mechanicalelectrical & mechanical

Conclusion• Human performance needs to be Human performance needs to be
optimized in tandem with optimized in tandem with machine performancemachine performance
• Therefore, training and interface Therefore, training and interface should be tailored to the human should be tailored to the human
• Cost will be worth the lowered Cost will be worth the lowered ratio of shuttle cost to expected ratio of shuttle cost to expected number of flightsnumber of flights
