How long can the human body endure the rigors of space travel?
In short: As crews ascend toward the International Space Station, scientists are racing to understand the physiological toll of long-duration missions. From the Soyuz launches in Kazakhstan to SpaceX Dragon missions from Florida, every voyage provides vital data on how human biology adapts to life in orbit.
The journey to the International Space Station involves complex coordination between international agencies like NASA, Roscosmos, and the Canadian Space Agency. To illustrate, the Expedition 43 team departed from Kazakhstan's Baikonur Cosmodrome on March 27 U.S. time. This mission included Soyuz Commander Gennady Padalka and Flight Engineer Mikhail Kornienko from Roscosmos, alongside NASA Flight Engineer Scott Kelly. Kelly and Kornienko aimed to investigate how extended spaceflight impacts human physiology. The crew's departure from the Baikonur Cosmodrome occurred on March 28 local time. The objective of this particular flight was to study how extended periods in space impact human physiology.
Modern missions continue this scientific lineage with the SpaceX Crew-13 mission. Scheduled to launch at 11:10 a.m. EDT on Thursday, Oct. 1, using a SpaceX Dragon vessel, this mission departs from Florida's Cape Canaveral Space Force Station, Space Launch Complex 40. The crew includes Roscosmos cosmonaut Sergey Teteryatnikov, CSA astronaut Joshua Kutryk, and NASA astronauts Luke Delaney and Jessica Watkins. NASA will offer live coverage of the prelaunch and docking activities. This broadcast will be available across various streaming platforms.
Understanding these biological impacts is essential for future exploration. While the Crew-13 mission is slated for docking around 7 p.m. on its launch day, the scientific data gathered during such long-duration science missions remains the cornerstone of space medicine. By studying how astronauts like Kelly and Kornienko adapt to microgravity, researchers aim to mitigate the risks associated with extended stays in low Earth orbit. A postlaunch news conference is scheduled for 12:45 p.m. following the launch. This event will feature several high-ranking officials from NASA and SpaceX.
