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: 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.

Radio batteries charged after EVA.
Spacesuit batteries plugged.
Summary of GreenHab operations:
Water use: 14 gallons
Heater: off
Supplemental light: off
Harvest: 191 gr of cucumber
Radios were found discharged: the jack plug of charger was half disconnected so the radios were not properly charged. This has already been solved.
Summary of Science Dome operations:
Laia Ribas (Green Hab Officer) prepared the setups for her experiments.
Neus Sabaté (Mission Specialist) brought rock samples from EVA and prepared the setup for further analysis of electroactive iron contents.
Dual split: off
Summary of RAM operations:
Cesca Cufí (Crew Engineer) used the RAM to start mounting her experiment setup (homemade biological safety cabinet).
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.

Static tank pipe heater (on or off): off
Static tank heater (On or off): off
Toilet tank emptied: no
Summary of internet: used from 18:00 to 21:00 for personal communication and reports.
Summary of suits and radios:
Suits: space suit number 2 found with the collar mounted upside down and with only one metal bridle (see attached picture “spacesuit_2”). It has been repaired with a spare metallic bridle.
Radios: short fail in communication channel 1 while in EVA to Marble Ritual on radio 2 and channel 2 on radio 5.
Radio 2: the COMMS EVA responsible, Mariona, was not able to hear the COMMS Station responsible on channel 1 for a couple of minutes. The issues appeared when the crew member Mariona was far away from the station but still on sight from the station (no terrain obstruction possible). The operation of channel 1 was switched to crew member Carla, the backup responsible. She maintained communication with the Station and reported the issue. The COMMS on channel 1 with radio 2 were recovered without specific troubleshooting. No troubleshooting was tried. The second EVA didn’t report any issues operating on the same channel around the same location.
Radio 5: the COMMS on channel 2 had some issues. The crew member was pressing the PTT button but the voice was not heard after some seconds. That is, there was a delay on the activation of the voice message (greater than the common delay). This issue appears when the crew member operating the radio was already back to the station, next to the Hub, and was getting off the rover. The crew member being close to the station and ready to enter the Hub, no troubleshooting was tried.
We will troubleshoot the future radio issues during the EVA on-site.
Both radios were working fine during pre-EVA check and most of the EVA time. Both radios have been tested after EVA and they work nominally.
We highly suspect a misconnection on the headsets plug, maybe due to the movement of the crew members.
All radio and spacesuit batteries checked before EVA: ok.
Radio batteries charged after EVA.
Spacesuit batteries plugged.
Summary of GreenHab operations:
Water use: 13 gallons
Heater: off
Supplemental light: off
Harvest: 1g (thyme, sage), 114 g microgreens, 56 g cherry tomatoes
Summary of Science Dome operations:
Transport of science material to the dome.
Dual split: off
Summary of RAM operations: none
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:
Cesca, Ari and Núria were back at the station at 11.30h this morning. Crew Engineer Cesca Cufí has been checked in Moab Regional Hospital for abdominal pain. After some exams: appendicitis discarded, it may be an intestinal infection. Cesca was given some antibiotics at the hospital last night and prescribed some antibiotics and pain killers for the next 5 days. Cesca feels a lot better, still with some pain but functional.

Questions, concerns and requests to Mission Support:
Spacesuit 2: to properly repair the spacesuit, we’ve searched for the metallic bridles in the RAM but we couldn’t find any. Do you confirm there are no spare bridles of this king in the station? If any, we will replace the plastic bridle for the metallic one. Thanks.
Update: The plastic bridle has been replaced by the metallic one.
