Nevertheless, as a result of a malfunction, they’ve been stranded on the ISS since their docking on 6 June, with Williams now marking over 150 days in orbit.
Well being Implications of Prolonged Area Missions
As per a report by DailyMail, Dr Vinay Gupta, a pulmonologist based mostly in Seattle, expressed concern after reviewing the latest picture, noting indicators of great weight reduction. He defined that the physique burns extra energy in house because it adapts to distinctive circumstances, requiring astronauts to devour high-calorie diets.
