Crew 265 Operations Report Sol 5 29-04-2022

SOL: 5

Name of person filing report: Dave Laude/Sergii Iakymov

Non-nominal systems: Furnace. Room#2 door knob. Percy’s left rear tail light is non-functional, but the brake light is working. Upper deck clock hour hand offset and one can be confused on the hour reading.

Notes on non-nominal systems: Furnace is functional and we remain cautious over limiting to early morning only. Infrequently used now. Door knob feels like it’s about to fail. Clock hour hand has been adjusted.

Summary of Hab operations:

WATER USE:

Water (static tank): Not full. ~342 gallons.

Water (loft tank): 55 gallons

Water Meter: 158169.2 units

Static to Loft Pump used – Yes

Static tank pipe heater (on or off): Off

Static tank heater (On or off): Off

Summary of internet: Nominal

Summary of suits and radios: Batteries charging. Six radio batteries have now been tested. Three are very good, one fair and the others only about 60% of full new capacity (still usable, but could deplete on long EVAs). It may be that some failed suit batteries that are accumulating are a result of over-discharge that could ruin standard SLA batteries. This could happen if the suit hasn’t been charged then used or the fan is not turned off upon returning from EVA. It might be helpful if the charger doesn’t get switched off from the battery when the fan is running. The charger could then supply the current needed to run the fan. There is a class of batteries called "deep discharge" that could better handle over-discharge if that is happening.
