Questions, concerns and requests to Mission Support:
Questions:
Today’s EVA has taken the team to Robert’s Garden Rock, which is relatively close to the base (approx. 1 mile) and the rover’s batteries discharged to 65%. We have observed that the batteries show a fast discharging rate at the beginning of the EVA and then keep discharging at a lower pace. Considering the Mission Support advice of not letting the rover’s batteries go down below 60% we would like to know if it is possible to plan a longer EVA that allows us to reach longer distances. Advice about this matter will be highly appreciated.
Requests:
Spirit rover: replacement of the corroded wire
Kitchen: knobs replacement
Retrieval of trash in the rear airlock

Summary of health and safety issues: we have replaced batteries of portable gas detectors. The exhausted batteries have been placed in a ziplog bag and left next to the B and NB bins in the lower deck.

Summary of other system’s issues:

Hab heater: it turned off about 2PM. No reason found. Crew Engineer and Commander troubleshoot the issue with the help of mission control. The heater showed the following Light code message: one short blink followed by 3 long blinks. The following actions were executed following mission control orders. The heater was turned off and on again, without results. Then the heater switch on the voltage panel was turned off and on again. The heater LED indicator was then constantly on, meaning that the heater was receiving 24VAC. After a few seconds, the heater turned on.

At 6.45PM the heater turned off again and it was troubleshot the same way.

Some bridles of the corridor tents were missing or broken after overnight winds. We replaced the damage with new bridles.

Questions, concerns and requests to Mission Support:

Spirit rover: replacement of then corroded wire

Kitchen: knobs replacement

Science dome: we have been organizing the science dome in order to fit all the planned experiments of the mission. Yesterday we had to move the microwave from one of the tables in order to have more dedicated space for biology experiments. Today, we allocated it in its original place but we realized that that space was needed to run the genome sequencing experiment. Therefore, we request to Mission Support the permission to store the microwave in a safe place during the mission and put it back to its original location once the experiments are completed. Attached you will find a pdf that explains how the different available locations of the science dome will be used and the suggested temporary location for the microwave.

Summary of any observatory issues: none
Robotic observatory: Not working. Replacement parts are scheduled to be installed during crew 261 rotation.
Summary of health and safety issues:
Gas stove knobs dammaged: the gas stove knobs are damaged and they don’t fit properly the valves axis, resulting in a serious hazard. Because of this reason, there was a gas leak during cooking lunch, while during the EVA. The two cooks detect immediately the leak but could not stop it immediately as the knob was not working and the other knobs neither. The leakage was stopped several minutes after by the crew engineer (cooking at this time) that turned off the knob axis using a pliers that she had in the Hab, while one crew member went to the RAM to pick a gas sensor to monitor the concentration of gas. After the EVA, to ensure the safety, the Crew Engineer explained the issue to all crew members. The HSO has recommended limiting the use of the stove to the single burner that has an actual functional knob while we find a way to repair the rest. A gas detector has been placed in the kitchen to measure the gas concentration in case we need to use several burners, to ensure all burners are off when finishing cooking. All crew members are aware and know the procedure to follow.
Questions, concerns and requests to Mission Support:
The gas detector that has been used to detect the gas leak from the kitchen stove has a very low battery level. Also the second one we found in RAM. We have looked for replacement but could not find AAA batteries in the RAM.
In case Mission Control refuses the crew repairing/substituting the knobs, we require spare parts to replace all of them (x4). We can provide the knob measures and pictures.
