The heavy logistics of human life in microgravity

Space · Published 12 October 2026 Swipe more like this →

In short: Sending humans into orbit requires more than just a rocket; it demands a complex choreography of international cooperation and rigorous terrestrial preparation. Before the Soyuz TMA-11M ever leaves the Kazakh steppe, the crew must undergo intensive training to manage the station's delicate balance of science and survival.

The transition from Earth to the International Space Station (ISS) begins with a high-stakes logistical handoff. Representatives from NASA, Roscosmos, and the Japan Aerospace Exploration Agency met within Russia's Star City at the Gagarin Cosmonaut Training Center on 26 October. This site serves as the final terrestrial staging ground where astronauts and cosmonauts undergo traditional ceremonies and final preparations before heading to the Baikonur Cosmodrome in Kazakhstan for their scheduled launch.

The mission profile for Expedition 38 is a dense tapestry of scientific inquiry. While the crew manages the daily operations of the station, they are tasked with high-level research including the study of disease and aging treatments. They also utilize advanced technology, such as lasers to analyze atmospheric gases and systems designed to beam massive quantities of data back to Earth. These efforts represent the core of the ISS's purpose: using microgravity as a unique laboratory for human health and physics.

Beyond the laboratory, the crew performs high-risk maintenance. During the 2013-2014 period, the mission included multiple spacewalks. For instance, Richard Mastracchio and Mike Hopkins conducted a 7-hour, 30-minute spacewalk on December 24, 2013, and a 5-hour, 28-minute walk on December 21, 2013. These extravehicular activities, combined with the management of cargo vehicles like Cygnus and Progress, highlight the constant physical and technical demands placed on the crew during their stay in orbit.
