In Mary Roach's book "Packing for Mars: The Curious Science of Life in the Void," she explores the peculiar practices and preparations involved in space travel. One of the more surprising details involves the Soviet space agency's pre-launch routines, which differed significantly from what one might expect. Instead of providing cosmonauts with a hearty meal of steak and eggs, they administered a one-liter enema, reflecting the unique challenges of maintaining health and hygiene in the weightlessness of space. This unconventional preparation highlights the often-overlooked aspects of astronaut training and the intense focus on bodily functions in space missions. Roach delves into these intriguing details, showing how even the smallest elements of a space journey are meticulously considered to ensure the well-being of astronauts during their time in the void. The juxtaposition of traditional hearty meals with such an unusual procedure underscores the complexities and surprising realities of life beyond Earth.
