Payloads Bacterial Adhesion and Corrosion: The crew gathered materials and performed the BAC inoculation. Polymicrobial Biofilm Growth and Control during Spaceflight (Bacterial Adhesion and Corrosion) explores the formation under microgravity conditions of multi-species biofilms, which may behave differently from single-species biofilms. This investigation identifies the bacterial genes used during biofilm growth, examines whether these biofilms …

The seven Expedition 64 residents living aboard the International Space Station will be going into the Christmas holiday focusing intensely on space biology. The entire crew will be off duty on Christmas day relaxing following an increased pace of microgravity research. Rodent research will be the highlight through Christmas eve as the astronauts explore how …

The seven-member Expedition 64 crew, consisting of five astronauts and two cosmonauts, will spend the rest of the year conducting valuable space research aboard the International Space Station. Tuesday’s slate of science investigations explored a range of space biology and physics phenomena to benefit human health and manufacturing. Results from these microgravity studies could also …

Payloads Astrileux The crew fabricated a protective cover for the Astrileux hardware to allow it to be returned to the ground for analysis. The experiment was retrieved from its external ISS location earlier this year.  NanoRacks-Astrileux evaluates the effects of space exposure on new materials that, for the first time, show optical performance in the …

Payloads Airborne Particulate Monitor (APM):  The APM hardware was relocated from the US Lab to Node 3.  This hardware is routinely moved to different locations to allow monitoring of the particulate environment in those areas.  Although requirements exist for maximum allowable concentrations of particulate matter, currently no measurement capability verifies whether these requirements are met. …

Science operations continue to expand aboard the International Space Station with the installation of a new research airlock over the weekend. The seven-member Expedition 64 crew also stayed busy exploring a variety of space biology and physics phenomena. Robotics controllers on Earth spent Saturday remotely commanding the Canadarm2 robotic arm to install the new NanoRacks …

NASA and Boeing engineers successfully completed propellant loading during the seventh core stage Green Run test, wet dress rehearsal Sunday, Dec. 20. The massive Space Launch System (SLS) rocket’s tanks were loaded with more than 700,000 gallons of liquid hydrogen and liquid oxygen. Engineers working in the Test Control Center monitored all core stage systems during …

Payloads Astrorad Vest: The crew continued with the assessment of the Astrorad vest and its impacts to various activities.  The AstroRad vest is a personal protective equipment (PPE) device which functions as a radiation shield for astronauts. The AstroRad shields astronauts from space-borne ionizing radiation in an efficient way, provides operational simplification, and allows for …

NASA Astronauts Stephanie Wilson, Jonny Kim, and Randy Bresnik take a look at the Orion spacecraft simulator that recently arrived at the agency’s Johnson Space Center in Houston. The simulator provides the ability for astronauts, engineers, and flight controllers to train and practice for scenarios during Artemis missions to the Moon. The interior of the simulator is …

The Expedition 64 continued its human research studies today while also focusing on space manufacturing and technology investigations. Spacesuit maintenance has also wrapped up for the week aboard the International Space Station. The lack of gravity in space is not the only factor affecting the human body. Solar radiation is also a concern as NASA …
