Summary of RAM operations : Use of 6 zip ties, 1 meter of blue tape, 50 cm of wire for an experiment, 1 meter of tape to measure the tank’s depth, and pliers to repair the toilet leak. No actual operations were conducted within the RAM itself.
Summary of any observatory issues: /
Summary of health and safety issues : Our crew engineer is steadily improving each day. As for other issues, we encountered minor incidents, such as cuts, for which we applied band-aids to Batoul and Arnaud. Additionally, a minor issue occurred in the Science Dome when the autoclave overheated, causing a power failure and triggering the gas alarms due to the release of a large amount of steam. We had to request assistance from Mission Support to resolve the situation.
About the inventory : 4 band aids have been used today, and 1 antiseptic towelettes.
