The International Space Station (ISS) will be run by a skeleton crew of only three astronauts following the medical evacuation of Crew-11. This downsizing raises concerns about the capacity of the station to conduct its regular scientific research and maintain its operations.
Crew-11, an international team of astronauts from Russia, Japan, and the United States, had been scheduled to stay on the ISS until the end of October. However, an undisclosed medical issue forced them to return to Earth prematurely, leaving only three astronauts to manage the station. The remaining crew members are Russian cosmonaut Anton Shkaplerov, who is the mission commander, as well as Japanese astronaut Akihiko Hoshide and American astronaut Mark Vande Hei.
The ISS, which has been continuously occupied since November 2000, is typically manned by a crew of six people. The reduction to just three astronauts will inevitably impact the volume and scope of scientific research that can be conducted. The station’s maintenance, which is essential to ensure the safety and functionality of the ISS, may also be affected due to the reduced manpower.
In the meantime, the space agencies involved are working on a solution to bring additional crew members to the ISS. NASA, Roscosmos (the Russian space agency), the European Space Agency, and the Japanese Aerospace Exploration Agency are all actively involved in these efforts. The next crewed mission to the ISS, Crew-13, is scheduled for launch in December 2021, but it remains to be seen if this timeline will be moved up to address the current situation.
The ISS serves as a critical platform for conducting scientific research in microgravity, which helps increase our understanding of a wide range of phenomena, including human health, fluid physics, materials science, and astronomy. It also plays a vital role in international cooperation in space exploration. Ensuring the smooth operation and safety of the ISS is, therefore, of paramount importance to the global scientific community.
The medical evacuation of Crew-11 underscores the challenges and risks associated with long-duration spaceflight. Astronauts on the ISS live and work in a harsh environment characterized by microgravity, radiation, and isolation, all of which can have significant effects on their health. This incident highlights the importance of ongoing research into the physiological and psychological effects of space travel, as well as the development of appropriate countermeasures.
