Non-nominal systems: Generator power system

Notes on non-nominal systems:

Ready for a long Engineering story? Following the generator failure early yesterday morning, I’ve been keeping an eye on the batteries and the battery charger. Yesterday, Sol 01, I removed the plastic covers from the posts to break out the “new” battery (with the sticker “9/17”), plugging that into the charger. As noted in Sol 01 Operations Report, I switched out the batteries in the evening, so the “old” battery (sticker “10/17”) that we had been using all the time was back in action. Though the batteries should supposedly last us 24 hours, the new 9/17 battery was unfortunately at a 50% SOC yesterday evening, after running the generator through our Martian daylight hours. This may be due to my lack of knowledge in the need to charge batteries before usage, and I would please request clarification on this requirement and possible effects of not charging before first use.

I mention this concern because today, Sol 02, has been a bright, sunny, and clear day… Perfect for spending the day taking trips through the tunnels to keep checking on an off-nominal battery charger! This morning, the battery charger showed 0% SOC after it was supposed to be charging the new 9/17 battery all night long! Too cold in the Science Dome maybe, even though I moved it inside? Also this morning, the generator indicated low battery and was running at only 9.3 V (lower than nominal 12 V). The rugged old 10/17 battery had charged all day, supposedly, but now apparently was at low charge after only running through the night.

Well, Max and I hooked up the multimeter he brought to check the voltages and amp draw on both batteries. At some point, the charger also began showing around 50% SOC on both the batteries. The charger was connected to the old 10/17 battery for several hours in the morning, and then was connected to the new 9/17 battery for several hours–in fact, all afternoon. Wrong SOC readings on the charger? The 50% generator battery SOC seems to be a small success, because the multimeter readings indicate the batteries should be full… On both batteries, now: 13.0 +/- 1.0 V and 5.5 +/- 0.6 A. Based on some battery knowledge and reading over a couple Schumacher Battery Chargers 10/2 A output, this indicated a fully charged battery. Small success?

The trusty old 9/17 battery has been plugged in this evening around 5pm when the Hab switched from solar power. The 10/17 battery was plugged into the generator at first, showing 100% SOC on the charger actually, but the generator failed to start. So I brought it back in and am leaving it plugged into the charger inside the Science Dome overnight.

We’ll continue to keep an eye on the generator system! The battery charger remains suspicious and on trial.

General notes and comments:

Curiosity rover was charging from the end of the EVA until the Engineering EVA, when I switched the cord to Spirit. However, I forgot to check the final charge on Curiosity after the Engr EVA, my apologies. We need 1-2 more extension cords in order to have all rovers charging at one time.

I took my first real Engineering EVA this evening with Commander Max! We trekked over to check the propane, unloaded some things for the little NorCal rover from the RAM, and I checked on a couple of our electric rovers. Tried out the Exo-Suit for the first time, too! Felt great at first and definitely so easy to slip on, and I appreciated it not hitting the back of my head like the other EVA packs–poor short Mel. Halfway through (which ws only after about 10 mins) I did feel some pretty uncomfortable strain on my shoulders. I’ll try adjusting it better next time.

Questions, concerns and requests to Mission Support:

Maybe we can find someone with more generator and battery knowledge to check out what’s been going on. I’ve tried to record everything in my notebook and summarize them for CapCom so far. Also, I replaced the air filter, and Shannon says this should become routine at the start of each rotation from now on.

Notes on ATVs: ATVs were nominal. They all need an oil change, especially the Yamaha 300, because the oil during my check was quite dirty and black. All got some oil added to them except the 300.

Today I went on an Engineering round to do a quick inspection of the ATVs: checked the oil and fuel levels, attempted to check tire pressure, and did a visual tire inspection. All results were nominal and nothing unexpected; however, I considered the quick inspection my due diligence as an Engineer on their first day! It was kind of entertaining for me anyway. Oil levels were about half-way so I added some from our stores (plenty of bottles of oil in the EVA storage room). I wanted to check the tire pressures, but unfortunately the little pen gauge is inoperational and the air compressor has a gauge without enough detail for me to get an accurate reading. All the tires seem in great condition though, and I looked for possible damage to the tire walls from going over a bad bump or something out here, too. Lookin’ good!

General notes and comments:

Sol 0 and as the Crew Engineer, I went around the hab for my checks while also looking things over to create a To Do list for my couple weeks here. Toilet got emptied (such fun), ATVs got a quick
inspection, and the front window replacement and back-up generator relocation was fit into the end of our EVA. I got confirmation from Shannon that we could try hooking up power to the RAM using the little back-up generator, so two crew were very helpful in wheeling it through the sand over there. We’ll just wait on the 30A cable to be delivered in a resupply mission soon, along with tools for the RAM! Yay! Finally, I also gave a little engineering brief to the crew–what to expect while they’re here with things like doors that don’t work properly and staying away from the power system and helping me record rover runtime hours.

A notable thing did happen today in that the generator failed sometime this morning. I’m not entirely sure what time, because the clock is not correct on it. Unfortunately, this means that I lost the runtime hours, too, so I can’t be sure how long it has been on. Fortunately, the Solar SOC showed 61% at that time, which is above our limit for concern. We are guessing that the battery died and that’s all. Because yesterday was cloudy and today might have been too, I left the generator on all day today but replaced the old battery with a new one. I switched the batteries again this evening, so now the new one is charging.

General notes and comments: Some clarification is needed about the water meter, but questions are below! It’s rather difficult to guess the gasoline used by the ATVs, though this will become easier when I have enough gasoline to fill them up and keep track from there. Also, I need to become better at checking the rover charges after use, so I apologize. Curiosity was plugged in without checking the ending charge, so when I went back out, it had already been charging for a little while. Otherwise, all is good, and we learned a lot from Shannon today in an effort to prevent dilution of knowledge during hand-off! The crew had a ton of fun toying around on the ATVs today for practice, becoming more comfortable with them. Then we were also able to drive around suited up, so this was a fun experience. Pretty surreal to walk around in the suits for the first time! What a first Mars walk today!

Questions, concerns and requests to Mission Support:

* Kitchen: The right handle of the sink isn’t working.

* Water: Ops report asks for a “Water Meter” reading. Is that (A) the value I see under the black cap with the “potable” label on it, up in the loft? Or is it (B) the level of the water (Gallons) in the loft tank (which changes a lot throughout the day, especially if I refill it)?

* Heat: Water heater is disconnected and Shannon said that Curtis needs to come back and fix the system, including allowing heated water to come back up to the kitchen. Also, we really need a better, stronger heating system because the current one can barely manage to bring the water above freezing, instead of the preferred ability to actually make the water feel heated.

* Hab Car: Needs an oil change please, the Check Engine light is on again (among other issues).

* RAM: Considering using the little back-up generator to power the RAM for special operations. Since the generator routine has been working well for now, we think the back-up should be ok in this usage. Crew Engineer with help from others will look into moving it and the wiring necessary in the coming sols.

* GreenHab: Axle needed for wagon — Carrie(?) comes back on 3rd to address this.

* ATVs:

– Rearview mirrors are REALLY needed, pretty please! Absolutely impossible to see anything behind you while in spacesuits, and I consider this a safety and operational Must. I’m absolutely willing to install them, and I feel relatively cheap ones could be found quickly online (Amazon?), if Shannon could receive packages.

– We need more gasoline– very low at around 0.5 Gallons left. I will fill the ATVs up and then be able to really track our usage.

* Generator: We turned the Generator back on after a couple hours in the morning when it was clear the Solar SOC was dropping rapidly. However, in the afternoon when the Solar SOC was back up to 100%, we turned the generator back off. This was not the proper decision. In the future, during cloudy days we will leave the generator on and plugged in the entire day. This is considering that we have a second battery (not known until this evening) and also a generator master guy in town said that we can trickle charge it– i.e. charge the battery and have it connected to the generator at the same time.

Name of person filing report: A.Passeron

Non-nominal systems:
– Generator :
We had the same problem over and over again with the generator. The battery is not charging while generator is on. At about 9:00pm, we unplugged the cable which connect the generator to the solar panel central unit, we jump started the battery and we turned the generator on. But the charge of the battery dropped and the generator had a second failure at rougthly 9:20pm. So the problem comes from the generator, not the central unit. At 8:10am, we jump started the generator again and turned it on.
At 9:10am, just before third failure, settings were :
+ Oil pressure : 47 psi
+ Speed : 1815 rpm
+ Battery charge : 6.4V
The generator had then a third failure at 9:20am.
Shannon and us agree with the idea of charging the battery during the day to run the generator during the night. Shannon brought two battery chargers at 4:35pm. We disconnected the battery from the generator and charged the battery at 4:50pm. We let the battery charge for two hours after the sunset. At 7:15pm, the charge of the battery was 60% while the SOC was 54%. We thus decided to connect the battery to the generator and it is working properly since then.

– Water shortage :
Crew aware of concern about water shortage. We use the shallow water from trailer tanks to water the plants of the GreenLab. Shannon brought an extra 100-gallon water tank to ease the water shortage. We pumped roughtly 60 gallons into the static water tank during the engineering check at 11:45am.

Name of person filing report: A.Passeron

Non-nominal systems:

– Generator :
The generator had a failure during the night, Fault message reading "Low battery". Jump-start from Shannon’s Shuttle battery at did not solve the issue. Generator had a second failure at rougthly 12:00pm. Second jump-start done and generator turned on at 5:30pm. The generator is currently running.
At 6:20pm, settings are :
+ Oil pressure : 45 psi
+ Speed : 1815 rpm
+ Battery charge : Fluctuating between 8.7V and 9.0V
At 6:40pm, settings are :
+ Oil pressure : 45 psi
+ Speed : 1815 rpm
+ Battery charge : Fluctuating between 7.8V and 8.0V
The charge of the battery is thus plummeting. The battery of the generator is not recharged while generator is on.

– Water heater tests :
I went to the shower and did the following tests.

@8:42am first trial with nominal settings (right dial on the second top black bar) :
hot water turned on all the way for 2 minutes, initial temperature 51F, final temperature 64F.
@9:33am second trial with max temperature (right dial turned to the top black bar, but I can go further) :
hot water turned on all the way for 4 minutes, initial temperature 55F, final temperature 64F.
