Atv Five Notes And Comments:

Comments:

>> @ 12:45pm the crew noticed that the heater was blowing cool air. I checked the heat vents throughout the HAB and confirmed that no heat was blowing through the HAB. I switched off the breaker for the central air, then opened up the panel. I noticed that 2 wires came out. I re-wired them back to their original position and turned the breaker back on. The heat began to blow through the vents again. Switching the breaker off/on caused power in the HAB to flicker. During the process, the pump was turned on automatically without notice of the engineer. This caused the tank to overflow and some water to spill out. The water was cleaned up and the situation has been resolved.

>> @ 2:15pm the vents began to blow cool air again and the water pump was not pumping (no sound of water or any other feedback from the pump). I switched the breaker(s) off and on, the pump and the heater reset. By 2:50pm the heat turned off again.

>> @ 3:30 to present the heat has stayed on.

>> ATV 3 and 4 are still not turning over, we brought in the batteries to try and charge them and see if this makes a difference. We did charge ATV 4 2 days ago but I am using a different charger in case the previous charger did not work.

EVA Suit Testing:

Pack 10 During a flat EVA we found a few issues with the helmet and the pack. The air tubes for the pack do not have the same joints as the old packs, which is creating a large amount of torque on the female pipe that is attached to the helmet. This puts the helmet at risk for cracking (which other helmets seemed to show). Because of the increased tension, this caused the tubes to pop out of their position (from the pack).

> The pack positioning on the frame was higher than the previous packs, which caused lots of discomfort as the weight is not distributed evenly. Despite working on the fans, the air was not blowing nearly as strong as the previous packs. Even if I opened up the bottom, I don't believe this would have increased the fan output.

> The pack was incredibly sturdy and a lot more durable than the other packs

> The helmet circumference became invasive in regular procedures and comfort of the user. There was also a lack of support from the back of the helmet, thus causing the helmet to force the user's chin to their chest. We tried to tighten the tethers at the pack harness of the helmet to the pack frame but it the angle prevented the ability to pull the helmet up very much.

> Overall, the user claimed that the pack caused soreness in his back, neck and traps due to the positioning and possible increased weight of the pack.
