Marrow Blood, Breath, and Ambient Air Sample Collection: Upon waking this morning, the crew took the Launch plus 4 day (L+4) blood, breath, and ambient air samples for the Canadian Space Agency (CSA) Marrow experiment which investigates the effect of microgravity on human bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on bone marrow and the blood cells that are produced in the marrow. The extent of this effect and its recovery are of interest to space research and healthcare providers on Earth. 3D Printing in Zero-G Experiment: After two consecutive weeks of successful 3D printer operations, today the ground team remotely operated the 3D printer to produce the final 3D printed test coupons in the Microgravity Science Glovebox (MSG). The crew removed and stowed all but the last batch, which will remain on the print tray, which will be returned on SpaceX-9 along with the rest of the coupons. Today’s operations bring the total number of coupons printed to 34, which includes a variety of 3D printed test coupons, including calibration, tensile, compression, and layer specimen coupons. The 3D Printing In Zero-G experiment demonstrates that a 3D printer works normally in space. A 3D printer extrudes streams of heated plastic, metal or other material, building layer on top of layer to create 3 dimensional objects. Testing a 3D printer using relatively low-temperature plastic feedstock on the ISS is the first step toward establishing an on-demand machine shop in space, a critical enabling component for deep-space crewed missions and in-space manufacturing. Mouse Epigenetics Setup Operations: In preparation for the Mouse Epigenetics experiment arriving on SpaceX (SpX)-9, the crew completed setup operations by reconfiguring the Cell Biology Experiment Facility (CBEF) video cable from the Image Processing Unit (IPU) to Video Compression and Recording Unit 2 (VRU2) and refilling the washer fluid of the Mouse Habitat Cage Unit before removal from the CBEF. The Mouse Epigenetics investigation studies altered gene expression patterns in the organs of male mice that spend one month in space, and also examines changes in the DNA of their offspring. Results from the investigation identify genetic alterations that occur after exposure to the microgravity environment of space. NanoRacks Plate Reader Locker Preparation and Hardware Relocate: In preparation for the arrival of the NanoRacks payload investigations on SpX-9, the crew relocated NanoRacks hardware from the NanoRacks Plate Reader installation location before removing and stowing the locker. NanoRacks Plate Reader is a laboratory instrument designed to detect biological, chemical or physical events of samples in micro-titer plates. Micro-plate readers are widely used in research, drug discovery, bioassay validation, quality control and manufacturing processes in the pharmaceutical and biotechnological industry and academic organizations. Space Headaches: The crew completed the European Space Agency (ESA) Space Headaches questionnaire to provide information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crew members in space. Headaches during space flight can negatively affect mental and physical capacities of crew members which can influence performance during a space mission. Waste and Hygiene Compartment (WHC) Pump Separator: Yesterday, the WHC pump separator light annunciated suggesting a malfunction of the pump. The crew brought the WHC to internal EDV and ran the separator for 3 minutes to drain any excess liquid. Following that drain, the light cleared and WHC was nominal for 3 uses while still on internal EDV. The crew reconfigured back to Urine Processing Assembly (UPA) and performed troubleshooting where the ground teams ruled out blockage in the UPA and cleared WHC for nominal operation. This morning the crew reported a high pitch noise coming from the WHC. Ground teams believe this could be an indication that fluid has traveled into the pump separator bearings. Crew performed an inspection of the interior of the rack and of the pump separator, which did not reveal any leaked fluid. The WHC continues to be go for nominal use. The installed separator pump has been in operation since January. Two spares are available on-orbit. Teams continue to monitor performance. Dragon On-Board Training (OBT): In preparation for SpX-9 arrival scheduled for July 20, the USOS crew participated in a conference with ground teams prior to performing proficiency training on the Dragon mission profile, rendezvous crew procedures and crew interfaces for monitoring and commanding. Mobile Servicing System (MSS) Operations: Yesterday, Robotics Ground Controllers powered up the MSS and maneuvered the Space Station Remote Manipulator System (SSRMS) into position for the start of the ISS Crew SpX-9 Offset Grapples Practice on July 15. Next they translated the Mobile Transporter (MT) from Worksite 6 (WS6) to WS4. At the completion of preparing the MT for the translation, Controllers noticed that Umbilical Mating Assembly 1 (UMA1) showed a status of both mated and demated on Channel A so they performed the MT translation on Channel B. They are investigating the issue. Today’s Planned Activities All activities were completed unless otherwise noted. MARROW – Ambient Air Samples Morning Inspection.
