“The X experiment runs automatically, and provides video to the ground of a process through which physicists study fluid mechanics. It runs at night to minimize effects of crew movements. Problem is, the experiment starts at 9pm and runs for 9 hours. If we must move around during that time, we float slowly, using minimal fingertip pressure for control.”

I’m learning how to put things “down” in space. For a while after arriving we spend a lot of time “temp-stowing” items we’ll be needing again in just a moment. But now, without even thinking about it, I’ve found that I place things in the air beside me so they’re easily available right away.

“Body hasn’t adjusted just yet. I still feel the pressure in my head of body fluids pressurized by my cardiovascular system still being shoved cephalad like on Earth. Lower GI system hasn’t adapted yet either…”

“If we must move around during that time, we float slowly, using minimal fingertip pressure for control…. All of us quietly and slowly swimming around reminds me of a family of dugongs.”

“I went down to the Soyuz, which definitely has good orientation. It is very comfortable [to sit there] and I am used to the visual picture…. I [my brain] needs a visual orientation system to reference.”

“I am getting good enough at floating around that it is second nature. It took longer than I thought to get good at that. My body is clearly still adapting.”

“I was floating back to the service module and am good enough now to make it all the way through the FGB and the PXO into the SM without touching a handrail.”
