The Soyuz MS-19 crew ship launched to the station today at 4:55 a.m. EDT, docked to the Rassvet module at 8:22 a.m., then the hatch to the station opened at 11 a.m. and three Russian crewmates entered increasing the space population to 10.

Japanese astronaut Akihiko Hoshide handed command of the station to European astronaut Thomas Pesquet during a traditional Change of Command ceremony today.

The next Commercial Crew mission to the station, SpaceX Crew-3, is targeting its launch to the station for Oct. 30 at 2:43 a.m. EDT. Commander Raja Chari and Pilot Thomas Marshburn along with Mission Specialists Kayla Barron and Matthias Maurer will live and work on the space station for six months. #nasa #esa #spacex #unitedstates #europe #astronaut #crew #dragon #crewdragon #international #space #station

Two rings to shear them all! This video shows a drop of insulin solution contained by surface tension in the Ring Sheared Drop device. The device pins a drop of liquid between two rings and rotates one while keeping the other stationary to create shear flow, or a difference in velocity between adjacent liquid layers. Researchers used the device to study protein aggregates called amyloid fibrils, which may be related to diseases such as Alzheimer’s, Parkinson’s, and type 2 diabetes. Researchers investigating the mechanisms of these diseases on Earth must contend with the forces of gravity and the interaction between liquids and solid containers. These forces differ from such interfaces in the body, such as those in arteries and brain tissue, and can affect results. The Ring Sheared Drop (RSD) experiment developed a device that uses surface tension rather than a solid container to hold liquids, something possible only in microgravity.    Fluid extracted after each run will return to Earth aboard a Dragon capsule on September 30 so researchers can determine the extent of protein fibril formation, study their structure, and compare both to what happens in ground-based controls. Results could improve the fundamental understanding of how amyloid fibrils form and are transported, as well as the effects of shear at fluid interfaces relevant to conditions in the body.   #spacestation #iss #research #space #science

The Soyuz MS-18 crew ship with three Expedition 65 crewmates docked to Russia's Nauka module at 9:04 a.m. EDT today opening up the Rassvet port for the Soyuz MS-19 crew ship next week.

A Soyuz MS-18 crew ship with three Expedition 65 crew members aboard will move from the Rassvet module to the Nauka multipurpose laboratory’s docking port on Tuesday. Live NASA TV (link in profile) coverage begins at 8 a.m. EDT. The trio will undock their Soyuz crew ship from Rassvet at 8:21 a.m. then redock to Nauka at 9 a.m. The maneuver opens up Rassvet’s port for the arrival next week of a cosmonaut and two Russian spaceflight participants aboard the Soyuz MS-19 crew ship. #roscosmos #soyuz #nauka #rassvet #nasa #astronaut #cosmonaut
