· (New Project): Some of the two-piece suits have slight variations in functionality. One of the suit’s battery displays don’t work, and another one has a rather noisy fan. I’d like to focus on these two tomorrow to see if I can fix them like I did with suit #10 today.

Summary of ScienceDome operations: Scanned an additional rock from Robert’s Rock Garden.

Dual split: Off

Summary of RAM operations:

· Space Suit: I performed a bit of troubleshooting and realized that all suits were functional and nominally charging, except for Suit #10. After opening up all one-piece suits, I realized that Suit #10 had an extra wire to power an embedded EVA Link unit (Astro #10). I removed that unit and unlinked the wire from the circuit, and it still had a weaker powered fan than the other suits. I finally swapped the Suit #10 battery with a fresh one and resolved the issue. All other one-piece suits function similarly. The dead battery was labeled as such and added to the existing dead 12V batteries in the space suit room.

· ScienceDome Radio Charger: I tried many different techniques to repair the charger but had no luck and ultimately returned it to the ScienceDome with a “Broken” tag taped on the front. I disassembled the unit and swapped power cords with functioning chargers and isolated the issue to the circuit board of the charger. I even re-soldered some components that I perceived as loose with no success. All work was done in the RAM, so no tools were removed.

· Showerhead Leak: After investigating the leaks, it was discovered that the three threaded ports were leaking. Plumber’s tape on each thread – along with cleaning the most upstream seal – removed all leaking. This will be a minor reduction in water consumption for the rest of the mission. A good amount of plumber’s tape was removed, and the roll was returned to the RAM afterwards.

· Golf Club: Crew Artist Gagnon has requested a 9-iron golf club to recreate a famous Apollo photo of golfing on the moon. I was able to craft a club out of a broom handle, a wall hook, and duct tape – although it does look more like a putter to me. I will return all these components to their respective locations after the photo is taken on a future EVA.

· Tunnel Zip Ties: I used 5 zip ties on the interior of the tunnel, and then an additional 10 on the exterior to secure the outer tarps to the tunnel mesh better. Snips were taken on EVA and returned.

Summary of any observatory issues: None

Summary of health and safety issues: None

Summary of RAM operations:

· Mousetrap Repair: The mouse trap that we received from Mission Support seemed to not fully function and when we caught the mouse last night, he easily got out when trying to move the cage. Looking up the trap brand online revealed that it is missing two retaining bars to keep each door shut once activate. Using about a foot of steel wire, these bars were fabricated and installed for the next attempt.

· Tunnel Zip Ties: I replaced two broken zip ties from the RAM and also used snips to cut some metal ties that were not holding onto anything. Duct tape was also added to the interior surface of any repairs that were made on the exterior from EVA 16 to make them more robust.

· Tunnel Repair: No major tunnel repairs to the tarp or zip ties were needed.

· Rear Airlock Door: The sliding bolt mechanism for the door has always been finicky and I wanted to upgrade it today. I added some eyelets to the bolt’s path and relocated the handle. It now slides only left to right instead of all over the place.
