Hallucinating astronauts

I’ve got a piece in The Observer about the stresses, strains and mind-bending effects of space flight.

NASA considers behavioural and psychiatric conditions to be one of the most significant risks to the integrity of astronaut functioning and there is a surprisingly long history of these difficulties adversely affecting missions.

Perhaps more seriously, hallucinations have been associated with the breakdown of crew coherence and space mission stress. In 1976, crew from the Russian Soyuz-21 mission were brought back to Earth early after they reported an acrid smell aboard the Salyut-5 space station. Concerns about a possible fluid leak meant the replacement crew boarded with breathing equipment, but no odour or technical problems were found. Subsequent reports of “interpersonal issues” and “psychological problems” in the crew led Nasa to conclude the odour was probably a hallucination. Other Russian missions were thought to be have been halted by psychological problems, but the US space programme has not been without difficulties. During the Skylab 4 mission, long hours, exhaustion and disagreements with mission control resulted in the crew switching off their radio and spending a day ignoring Nasa while watching the Earth’s surface pass by.

The piece also tackles a curious form of hallucination caused by cosmic rays and the detrimental effects of zero-gravity of brain function, as well as some curious Freudian theories from pre-space flight 1950s about the potential psychological consequences of leaving ‘Mother Earth’.

Enjoy!
