ISS Daily Summary Report – 4/01/2020

Fluid Shifts: The crew performed the setup for baselining eye Fundoscope images. Fluid Shifts is a NASA investigation, divided into Dilution Measurements, Baseline Imaging, and Imaging with Chibis. The Chibis hardware is used to perform the Lower Body Negative Pressure (LBNP) part of the experiment. The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes.  Because the head-ward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a LBNP device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and prevention of eye damage.

NanoRacks Module-51: The crew performed and photo documented the second Vitamin C flask experiment status check. This completes the operation objectives for Module-51. These sub experiments are the Vitamin-C Flask with syringe, Waxworm flask, Adipic acid and Venom flex plates, Yeast and amylase mixture tubes, and Flask with Flatworms.  Inspections of the experiments went well and the hardware was stowed.  NanoRacks Mod-51 itself is an aluminum module with a Velcro lid that can accommodate various sub-experiments.

NanoRacks Module-9: The crew performed the operations on the NanoRacks Module-9 tube which involves the mixture of Tube #2, which studies the ability of Quinoa (a type of grain) growth in microgravity. NanoRacks-National Center for Earth and Space Science Education-Gemini includes 41 microgravity experiments designed by students in grades 5 through 12 and college. The experiments range from examinations of water filtration and purification to synthetic soil production, rust formation, antibiotic effectiveness, growth and development of micro-aquatic organisms, and growth of plant, fungi, and bacteria. Each was chosen from more than 3,000 entries submitted by more than 23,000 U.S., Canadian, and Brazilian students. The experiments use NanoRacks MixStix, miniature laboratories activated by the ISS crew and are eventually returned to the student teams on Earth for analysis. 


Mobil Servicing System (MSS) Operations: Tonight, robotics ground controllers (ROBO) will power up the MSS and maneuver the Space Station Remote Manipulator System (SSRMS) and the Special Purpose Dexterous Manipulator (SPDM) to install the newly arrived Bartolomeo Science Platform. Installation is expected to be completed on Thursday morning at ~1:00 am CT.   Once installed, ROBO will finish deploying the remaining platform booms Thursday evening at ~9:00 pm CT.

The European external platform ‘Bartolomeo’ is an enhancement of the ISS European Columbus Module and its infrastructure. Designed to meet user requirements from the commercial and institutional sector, Bartolomeo is a new external payload hosting facility on the ram side of Columbus that is mechanically attached to the ram-facing primary and secondary trunnions, and uses the Columbus Parking Position Interface (PAPOS) for electrical and data interfacing. 

SpaceX-20 (SpX-20) Dragon Cargo Operations: Today, the crew continued to perform Dragon cargo operations in preparations for Dragon departure on April 6, 2020.

Water Processor Assembly (WPA) Multi-filtration (MF) Bed Sample Collection: Today, the crew performed a Life Support Rack (LSR) hose reconfiguration in preparation for a WPA MF Bed return sample collection. The crew previously experienced an issue with connecting a hose normally used to take MF bed samples; and as a result, ground teams had the crew reconfigure the LSR hoses to free up a like hose to re-attempt return sampling. The hose taken from the LSR was connected to the WPA nominally and the WPA MF Bed SpX-20 return sample was collected.

Systems Operations Data File (SODF) DEPLOY: Today, the crew replaced their Medical Checklists and EVA wrist Cuff Checklists with updated documentation delivered on SpX-20. The retired EVA Cuff Checklists will be returned on SpX-20.
