ISS Daily Summary Report – 7/21/2020


Food Physiology: The crew performed the setup for Saliva collection in support of the Food Physiology study. The Integrated Impact of Diet on Human Immune Response, the Gut Microbiota, and Nutritional Status During Adaptation to Spaceflight (Food Physiology) experiment is designed to characterize the key effects of an enhanced spaceflight diet on immune function, the gut microbiome, and nutritional status indicators. These factors are interlinked, but diet is the only one that can be easily and meaningfully altered on Earth or during flight. This investigation aims to document the effect of dietary improvements on human physiology and the ability of those improvements to enhance adaptation to spaceflight.


US Extravehicular Activity (EVA) #68: Today, FE-11 Bob Behnken (EV1) and ISS CDR Chris Cassidy (EV2) completed US EVA #68 (S6 Battery EVA #4). Following a very successful EVA last week, the crew had minimal cleanup at the Integrated Equipment Assembly (IEA) during today’s EVA. This allowed the crew to perform the following tasks:

  • Robotic Tool Storage (RiTS) Installation
  • H-Fixture Removal (1A and 3B)
  • Nanoracks Airlock Preparation
  • Camera Port 3 (CP3) Ethernet Cable Routing
  • CP13 Ethernet Cable Routing & Camera Lens Filter Removal

The crew was able to remove the H-fixtures today utilizing a set of modified pliers. The crew deferred a similar task during EVA #2 when they encountered difficulty attempting to remove the H-fixture. Ground teams developed a workaround tool by modifying a set of damaged pliers scheduled for disposal on HTV9.

Completed Task List Activities:

  • None

Today’s Ground Activities:
All activities are complete unless otherwise noted.

  • CMG Maneuver to Stage TEA
  • Ground Support for EVA #68
