Sunita Williams and Butch Wilmore, two NASA astronauts, are back on Earth after spending nine months aboard the International Space Station (ISS). What was initially planned as a shorter mission turned into an extended stay, marked by technical hurdles, scheduling delays, and complex logistical challenges. Prolonged space missions take a significant toll on astronauts' mental health, affecting their emotional well-being both during their time in orbit and upon their return to Earth.
Dr Shaunak Ajinkya, Consultant Psychiatrist at Kokilaben Dhirubhai Ambani Hospital, Mumbai, and Dr Gorav Gupta, Senior Psychiatrist and CEO of Tulasi Healthcare, New Delhi, weigh in on the mental health challenges astronauts face both in space and upon their return to Earth.
