The expedited mission aims to replace four astronauts who were medically evacuated last month, marking Nasa’s first such incident in 65 years of human spaceflight.
The new crew, including Nasa’s Jessica Meir and Jack Hathaway, France’s Sophie Adenot, and Russia’s Andrei Fedyaev, will bring the ISS back to full staff upon their arrival.
Their mission is anticipated to last eight to nine months, stretching until autumn, and they are expected to arrive at the orbiting laboratory tomorrow.
During their time on the ISS, the astronauts will conduct experiments, including testing a water filter for emergency IV fluid and an AI-powered ultrasound system, in preparation for future moon and Mars missions.
