Atv Five Notes And Comments:


 Today I worked on writing up some of my test results for the dust study and had a look at some of the broken space suits. To fix the broken air tube on suit 2 I decided as a temporary measure to swap it with one of the tubes in good condition from suit 5 since this was one of non working suits. This is what is colloquially referred to in the maintenance world as ‘cannibalising’. I might look at putting together a new tube tomorrow since there were a couple of spare tubes pieces around. 
I also opened up the back pack on suit number 4 and found that it was not working because a wire had become disconnected from the switch. I managed to solder it back in place and the suit is functioning well now. I took a look inside suit 5’s pack but couldn’t find any obvious connection problems. I used a voltmeter across the battery and it shows about a 12V voltage drop which indicates that it has a charge. I found that when the charger is plugged into the charger connection in the pack though that it doesn’t light up to show it is charging or fully charged. I suspect there is some connection problem near the charger area but it’s not obvious yet what is going on. I will look at it more tomorrow.
I also helped David out while he worked on assembling the quad copter. This mainly involved watching to see what I could learn and holding a torch but I also helped with the idea of using a petri dish as a case for the main circuit board. You can often come up with some interesting improvisations with the equipment and tools available here.
