Inventory of salvaged parts was taken today to determine if any components could be utilized for the irrigation system. Some components, such as valves and slip-thread adapters, were deemed useful and will be incorporated into our design. One integral component, a slip-slip valve, was ordered to control separate flows and will arrive Thursday by cargo ship.
Multiple design iterations were sketched to maximize pump efficiency while minimizing material use. A temporary design will be implemented tomorrow after our first EVA on Mars. This design has only one valve for controlling flow to the entire tray. The new valve will be added to the system to allow for separate control on each side of the tray.
