- Description
In preparation for his second mission to the International Space Station, ESA astronaut Thomas Pesquet is training to be ready for launch. His second six-month mission is called Alpha and will see Thomas launch as part Crew-2 on the SpaceX Dragon spacecraft with NASA astronaut Megan Behnken and Shane Kimbrough and Japanese astronaut Aki Hoshide.
This video shows scenes from Thomas Pesquet training for the Suture in Space experiment at the European Astronaut Centre in Cologne, Germany. This experiment will fly during the Alpha mission.
As humans travel farther from our home planet, we need to prepare for medical emergencies occurring where there are no hospitals. On the International Space Station, injuries are avoided at all costs but astronauts are never far from home; in a worst-case scenario they could land on Earth in hours.
Wound healing is a complex process in our bodies and no one has adequately explained why mammals scar or heal imperfectly rather than regenerate fully.
The Suture in space experiment will look at how tissues heal in weightlessness. Living tissue from biopsies will be cut and sewn back together, before being sent to space where astronauts will activate the cells to monitor the healing mechanisms. The samples will be frozen at set times to track how they progressed in space.
The study will help understand how humans heal, but the preparations for Suture in space have already developed a new technique on Earth that keeps tissue biopsies alive for longer periods, aiding studies in laboratories on transplants, cell regeneration and surgical techniques.
