Fluid Shifts Dilution Measurements: The 48S subjects initiated their Return minus 45 (R-45) Fluid Shifts Dilution Measurements activities, beginning at wakeup the subject collected saliva, blood and urine and insert them into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) prior to ingesting a Sodium Bromide (NaBr) tracer. Throughout the day, the crew performed …
Three Expedition 50 crew members recently surpassed 100 days in space and will come home in June. Also, SpaceX Dragon external experiments are being unloaded for installation on the International Space Station. NASA astronaut Peggy Whitson has been living in space with her Expedition 50 crewmates for over 100 days now. She and Thomas Pesquet …
Lab Carbon Dioxide Removal Assembly (CDRA) Maintenance: Yesterday the crew installed the newer generation beds, like those in Node 3 CDRA, into Lab CDRA. Today, the crew repaired the CDRA Valve Power Cable W9P12 by splicing in two new wire segments and performing a 120V power check of the connector prior to installing CDRA into …
The International Space Station fired its engines Wednesday night slightly raising its orbit to accommodate a crew exchange in April. In the meantime, the six-person Expedition 50 crew continued learning how living in space affects the human body. The station’s third module, the Zvezda service module which launched in 2000, fired its main engines for …
Lab Carbon Dioxide Removal Assembly (CDRA) Maintenance: Yesterday the crew removed Lab CDRA from the rack, and disassemble it by removing all of the valves and ducting to access the beds. They also removed the old beds. Today, the crew installed the newer generation beds, like those in Node 3 CDRA, mated Hydraflow Couplings, and …
The International Space Station will boost its orbit Wednesday night to get ready for a crew swap next month. Three Expedition 50 crew members will complete their mission and a new two-person crew will launch to the station in April. Commander Shane Kimbrough and his crewmates Sergey Ryzhikov and Andrey Borisenko will end their mission …
Lab Carbon Dioxide Removal Assembly (CDRA) Maintenance: The adsorbent material (Zeolite) inside the CDRA beds breaks down over time and creates dust. This dust eventually reduces airflow through the beds to the point where CDRA can no longer operate. The Node 3 CDRA has newer generation beds that can be disassembled and serviced on orbit. …
Astronaut Thomas Pesquet of the European Space Agency cleaned U.S. spacesuit cooling loops and collected water samples for a periodic maintenance check today. Afterward, he began charging spacewalking gear including helmet lights and tool batteries. Commander Shane Kimbrough and NASA astronaut Peggy Whitson worked on life support maintenance today. They removed and disassembled valves and …
Rodent Research-4 (RR-4) Transfer Operations: Saturday, the crew reported all of the animals were successfully transferred them from the SpX-10 transporters to the four Rodent Research Habitats on the ISS. Sunday, the crew cleaned and stowed the transporters. The Tissue Regeneration-Bone Defect (RR-4) studies what prevents vertebrates such as rodents and humans from regrowing lost …
The Expedition 50 crew began activating new science experiments delivered last week aboard the SpaceX Dragon. The various life science studies will study bones and muscles, stem cells, botany and protein crystals. Rodents delivered aboard Dragon were placed in their habitats over the weekend for the Rodent Research-4 study. That experiment is observing how bone …
