Commander's Check-In
Gus Frederick Reporting
Crew Status: Crew is in great spirits. Today was not going to be as intense as yesterday, but started off hecktic.
Daily Recap: It was Alyssa and my turn to fuel the China Special generator at 0600. The winds from last night continued into the morning. I was awakened around 0530 to the beeping of the Carbon Monoxide sensors, which screech when they loose power. I heard several such screeches, so decided to get up. Alyssa was already up, and we seemed to be having intermitant power fluxes. I decided then that it might be prudent to shut down the generator until after the winds died down. I roused Gregorio, and he and I headed down the stairs while Alyssa shut down systems upstairs.
We got to the lower level in time to smell something electrical starting to burn. Gregorio sprang into action and hit the main circuit breaker and shut down the system. After some trouble-shooting, it was determined that the extension power box I had brought for my data acquistion computer had shorted out, despite the fact that it was not powered up. So I unplugged that. Steve and I headed out to the generator, which was still running, and I noticed a large panel of former GreenHab material, that had apparently blown over from the debris field south of the Hab, was whacking the main power connection of the generator, which was a bit loose anyway, due to poor workmanship and(or) design. I pulled it clear, and after watching it run for awhile, we decided to refuel, and monitor the situation.
Back in the Hab, we powered up one breaker at a time, and things returned to normal, as the winds slowly died down. After breakfast, I checked the Data Acq system's extension was fine, and powered up without incident. I then connected to the Onset Weather Station, and downloaded the first day of recorded weather data. I reformatted the data, and created several charts in an Excel Spreadsheet. I forwarded this to GreenHab Coordinator Gary Fisher as well as Mission Support. More details on this information are in the Weather Report. The most interesting variable was the recorded wind speed. We had one gust the night before around 2040 that literally shook the Hab. This was clocked by the weather station at 83.60 kph.
Thankfully, the rest of the day went without major incident. One EVA was performed in the early afternoon by Kathleen and Greg Michael. I worked in the GreenHab to tweak the Salad Machine and photo document the locations of the Weather Station sensors. Alyssa completed reorganizing the tools. And around noon, Don arrived and hauled the trailer back to town to fill up the water tank and empty the trash. The right-rear tire on the trailer was flat when we arrived, so I filled it up with the Hab's compressor that Don pointed out. I also created a number of digital time lapse sequences of clouds through the Hab's main porthole.
Tomorrow's Plan: More EVAs, specifically, Gregorio and I plan to take the Pressurized Rover out to several Mars Analog sites identified by earlier sorties. Other EVAs are planned, but locations are yet to be determined.
