At around 12:02 a.m.EST on Thursday, December 20th, three members from the International Space Station returned home safely after the team’s long 197-day mission.

The mission included a host of experiments in a wide range of sciences in space’s very unique and harsh environment.

Landing in Kazakhstan, the Expedition 57 crew had three astronauts return home, Sergey Prokopyev of the Russian space agency Roscosmos, Serena Auñón-Chancellor of NASA, and Alexander Gerst of the European Space Agency.

Impressively, during their 197-day journey, the Expedition Commander circled the globe 3,152 times traveling well over 83 million miles.

 As mentioned above, there were hundreds of different experiments that were conducted during the mission. These experiments included progress in biology, biotechnology, physical science, and even earth science.


Nevertheless, some of the most interesting experiments conducted during the mission include new potential treatment methods for cancer as well as the further investigation of algae growth in space.   

The team also had the opportunity to test out the new Life Science Glovebox.

As stated by NASA, this research area “is a sealed work area that accommodates life science and technology investigations in a “workbench” type environment. Due to its larger size design, two crew members can work in the LSG simultaneously.”

Some other major milestones of the trip include Alexander Gerst’s ESA record breaking 362 days in orbit before finally coming home, while this is the first flight for Auñón-Chancellor and Prokopyev.
