Here are the science updates, sol records, and journalist post from the team at the Hab on the fourth sol of their mission. Check out Facebook for posts including the photos from each day.
Journalist Report – Sol 4
It snowed for a few hours today. That’s not supposed to happen.
Going to have to put some serious effort into revamping our understanding of Mars’ climate. Coldest day since we landed. The EVA crew decided to postpone until tomorrow due to potentially inclement weather. I’m not on tomorrow’s crew, but we might need to reprioritize some climate data while they’re out.. Will keep investigating.
Otherwise, today was a slow day. Some progress was made in the greenhouse, and the network connectivity issues persist despite many hours of messing with it. Felt like a snow day in elementary school where you’re off class and can feel christmas around the corner.
Our crew engineer engineered some cinnamon raisin swirl bread and it’s magical. The freeze dried food stores will probably start to wear on us eventually, but for the time being we’re living it up. As long as coffee and tea holds out, crew morale is going to be coasting just fine.
Connor and I’s sleep schedule is holding out strong. We aren’t being too strict about the schedule and we aren’t going too extreme – still a solid six hours or so per night, spaced into ~3 naps. We’ve been ever so slightly tired but that’s to be expected on the first day or two. Generally feel pretty energized though.
The most annoying thing at the moment for me is just being cooped up in a tin can. Really struggling to understand how all those super smart engineers on the ground decided a treadmill wasn’t necessary. Yoga and pushups only get you so far. The hab’s air system isn’t exactly refreshing either. Meh. It’s all good though. I’m sure we’ll get used to it. Or at least, we’ll be gone before it really starts to get to us.
We did find a massive binder of awesome (mostly old and/or super goofy) movies, so that’s helping the nights pass faster after work is done each day.
Nothing too crazy. The days are moving by faster as a whole.
Science Log – Sol 4
EVA Proposed Plan SOL 5 – We had to cancel the EVA for SOL 4 due to the inclement weather here at the HAB. For SOL 5 we propose the same format of EVA as SOL 3 but for the other three crew members who did not set out on SOL 3 (Geoffrey, Brittany and Sean). They will go to the dinosaur quarry and explore via rover. They will also take a GPS and map in order to gauge how easy it is to navigate to a precise location. The coordinates of this final location are the same as SOL 3: Northing: 4257412, Easting: 518238 Zone 12S.
Greenhab, Sean Gellenbeck – HSO and Greenhab Officer #2
Today marked the completion of the transplantation effort in the GreenHab. We have assembled eight total conveyor trays (four Red Oak Lettuce and four Green Oak Lettuce in both hydroponic solution and in soil) and one tray with a density experiment which was planted in soil. The slow process of sealing the GreenHab also began today. We have continued to notice that despite the near continuous operation of the heater, the GreenHab does not stay within an acceptable temperature range. At night, the temperature gets down to between 48 F and 54 F which is not conducive to productive and rapid plant growth that is necessary to sustain a healthy astronaut’s diet. In order to help prevent some of the theorized leakage of heated air, clear caulk is being used to seal the places at the top of the GreenHab where air could escape. This is a difficult process as the materials from which the GreenHab is constructed are clearly not meant to be used for a greenhouse. We are concerned there may not be enough caulk on Mars to seal the GreenHab. I hope future crews can figure out how to stabilize the temperature. Finally, the seedlings are germinating at excellent rates! We can easily identify growth in the radish, green and red oak lettuce, carrot, and mystery crop. Yay mystery crop!
Geology, Connor Lynch – Crew Geologist/Astrophysicist
Today no one had an EVA due to the inclement weather. We noticed that over the past 24 hours the temperature has remained very constant due to these clouds that have been around. The air has also spiked in humidity this afternoon which could be a factor in keeping the daily temperatures stable. The temperatures in the GreenHAB have also remained steady. The desired temp is 75 in the GreenHAB all the time, so this is an improvement from the wild temperature fluctuations the first couple days.
An interesting observation is that even though today the solar radiation was lower due to the clouds, the UV flux stayed about the same as past days. Proof that even on a cloudy day you need sunscreen!
The barometric pressure is lower today and has been dropping slightly this afternoon.
Outdoor Temp – 29 F – 35 F
GreenHab Temp – 53 F – 68 F
GreenHAB Humidity – 18% – 46%
Barometer – 29.52 – 29.92 inHg
Wind – 1.5 mph, gust – N/A mph
Solar Rad. Max – 173.9 W/m^2
UV Index – 526 uW/cm^2
Outdoor Humidity – 35% – 98%
