Operations Report – April 29th

Crew 193 Operations Report 29Apr2018

SOL: 7

Name of person filing report: David Attig

Non-nominal systems: Two piece suits still need straps adjusted for neck ring. Generator/inverter/charger. One piece suit #10. Soldering Irons
Notes on non-nominal systems: The generator still appears to not be charging the batteries at night (only powering the HAB). Shannon is having a look, this should not affect our operations (particularly with the days being so long now).
I will repair charging plugs once we have a soldering iron.
One piece suit #10’s fans stopped when I bent over while wearing the suit. The loose connection was determined to be at the positive terminal of the battery; upon inspection, there was a cold solder joint on a terminal connector. While removing tape to access battery terminals, I broke the small wires on negative terminal. Suit #10 is out of service until we have a working soldering iron (should be on the way).
