General notes and comments: The Hab Director mentioned that the Rovers required an extension cord that is shorter than 25 feet. We estimate the cords being used now are 50 foot cables. I was able to find a 25 foot extension cable, meaning we could charge one rover at time based on the above specifications. Can we have the appropriate extension cables sent to the Hab in order to charge the Rovers?
Also, the configuration the rovers are in means that the rovers need to back out before they are used. Backing up in an EVA suit is hazardous since you can’t see behind you in a suit. Please advise if there is another configuration that allows charging with a 25 foot extension cable as well as the ability to drive forward during EVAs.
Summary of internet: Internet connectivity continues to be a problem even with the data purchased. Devices are having troubles connecting and
Summary of suits and radios: There is a bent clasp on suit #1 on the helmet collar. It was probably bent during the EVA, the system is still functional.
Summary of Hab operations: The microwave isn’t working anymore. The buttons work, the time counts down, but the microwave doesn’t actually produce waves to heat anything.
Summary of EVA operations: We are still brainstorming ways to combat the helmet fog. Without proper ventilation under the helmet ring, the facemasks rapidly fog up. It is becoming a safety issue on EVA.
Summary of GreenHab operations: The temperature gauge display has some non-functional LCD areas, a new one has been ordered.
Summary of Science Dome operations: The science dome is awaiting a portable heater as per the Hab Director. Summary of RAM operations: Not Operational.
Summary of health and safety issues: The propane detector has arrived, and there is a positive detection of combustible gas in the hab.
We calibrated the sensor outside, and moving the detector in different places in the Hab clearly shows that there are areas where there is a higher concentration of combustible gas than others. The instrument is of low quality and does not show us the ppm, so we have no way to tell what the levels are, and if they are dangerous.
The leak was found using soapy water, and the fitting was tightened by the crew. We will investigate tomorrow and hopefully the leak is fixed. Questions, concerns and requests to Mission Support: All nominal [end]
