The main research topics were the International Space Station, foams, fires, and liquids in space to improve the quality of life for humans outside the Earth. At the end of the month, the Expedition 67 crew checked out a new U.S. toilet while gearing up for crew departure activities.
On Thursday, several space physics research experiments took place in microgravity, and the crew explored how weightlessness affects a variety of phenomena that humans are familiar with on Earth. The lack of gravity impacts the characteristics and behavior of earth-bound phenomena. New properties and insights were also revealed to help scientists and engineers develop advanced products and applications for the benefit of astronauts and Earthlings.

Looking at the sample configuration!

Jessica Watkins, the flight Engineer, focused her attention on the Foams and Emulsions experimenting with samples in the KERMIT microscope to improve consumer products.
Kjell Lindgren, the NASA flight Engineer, swapped samples in the Microgravity Science Glovebox for the Ring Sheared Drop fluid physics study to learn about high-concentration protein fluids and enable the production of next-generation for treating cancer and another upcoming disease. 

Samantha Cristoforetti, a European Space Agency astronaut, reconfigures the Solid Fuel Ignition and Extinction investigation components. 

Based on human research!

Bob Hines, NASA Flight Engineer, started the day with the test for the standard Measures where the human research experiment to characterize the adaptive response and risks of living in space. The testing performance of the new U.S. toilet systems located in the station's Tranquility module. 
The crew has been living and working on the space station for six months, and three cosmonauts are nearing departure. Oleg Artemyev, the commander, staged cargo for packing inside the Soyuz MS-21 crew ship that docked on 18th March. Denis Matveev and Sergey Korsakov started preparations for their trip back to Earth at the end of September. On Thursday, Matveev investigates improving the space lab environment for biotechnology experiments. Korsakov investigates electronics and computer maintenance.
