Crew 222 GreenHab Report – 26/02/2020

GreenHab Officer : Bleuenn ROIRON

Environmental control : Both heating and ambiant, window open during
the afternoon

Average temperatures: 21°C

Water in blue Tank: 47,5 gallons

Time(s) of watering crops: 3

Changes to crops: NA

Narrative:This morning, I was in EVA so Marie took care of the GreenHab
and watered plants, also harvested some herbs for our lunch.
During the afternoon, I had to water again tomatoes, and exposed
Watercress to UV and music. Tonight i watered again plants, finally
the cucumber that is pretty big and is very appetising! I also harvested
some salad(buttercrunch) and herbs for tonight! Lot of fresh things in

Chives: 11g
Sage: 5g
Cucumber: 1 (180g)

Support/supplies needed: 2 of the GreenHab lights aren’t working above
the aromatics herbs

Dr Shannon replied ” We can work on those lights on Saturday. I don’t
think I want to
replace those bulbs, because we will stop using the supplemental light
soon, but I do want to switch them around so the tomatoes have all
four working bulbs.”

Title: Pale white dot

Today’s EVA team headed North to the Ridge by foot. They found a way up the hill and had a long walk back to the Hab. It was fun seeing them in the distance from a Hab window! They looked like tiny ants walking along the edge. Seeing the white Hab from far away was impressive: it’s the only man-made building in the visible region around us. It feels like we are alone in the universe. During the climb, what struck them the most was the red, unfertile sand that really looks like Martian soil. There are no animals to be seen, and the few plants that grow don’t look like a sustainable life form.

After lunch, Eishi showed us his solar observatory. He calibrated the telescope, and we could see clearly the Sun in the visor! Unluckily, we are right in the middle of the “low activity” period of the sun, so all we saw was a giant red ball. The red comes from the filters that allow us to look directly at the Sun, without them it would burn our retina instantly. In a few years, Astronomers will be able to see prominences, sun spots, or even flares and filaments! Judging from the photos on the manual, it looks impressive. We might come back in 5 years to see it with our own eyes!

Valentin and I almost finished working on his LCVG on his afternoon. We finished joining together and waterproofing the tubes through which the cold water will run. The whole system works well, and we found no leak! Tomorrow, we will test it out and see if the suit truly makes a difference when outside on EVA.

We only have a few days left here, and we really feel like we have grown up during our time here. Our organization improved, we all get along great, and we have created a routine that suits all. It will be very strange to face the real world again.
