Summary of suits and radios: Batteries charging. Suit 10 now has a new battery (tested 6.2 A-Hr). We are finished checking for problems and repairing all suits and chargers although we are short one working charger. We opened it up and it needs a replacement 10uF/25V cap we don’t have.

I want to elaborate on yestersols comments I made:
Notes for Scott Davis re. one-piece suits from Dave Laude (5’9" 134 lbs small frame). I have used them about 8 times and like them. There are a few improvements in my mind that would make them fantastic for me:
1-Some of us want to carry the bulk of the weight on our waist as the shoulders get sore otherwise. The straps have a limited capacity to do so I found because the "overhang" part of the suit above the shoulders contacts the shoulders when attempting to transfer much of the weight to the waist by loosening shoulder straps. Suggest an arch be cut above the shoulders. Note that the waist belt is tight.
2-There is too much transparent area in the helmet allowing too much hot sun on the top of the head where there are no eyes. Consider making top opaque.
3-Suggest you use barrel connectors for charger port as we discussed before. More reliable and much easier to plug and unplug. I suppose easy could result in accidental pull out, but astronauts should be able to manage it.
4-Please consider adding padding on the inside sides of helmets like on the backside. What happens in rovers on rough road spots is the rover will swing side-to-side throwing one’s head into the helmet hard sides. Extremely annoying and brain rattling.

Questions, concerns and requests to Mission Support: Per our calculation the water meter is pretty accurate. The meter is only 2.5% off on its readings from our calculated water usage. More on our "calculations" tomorrow.
