Good news from the GreenHab: less than 24 hours after seeding, radishes have already

germinated. A few seeds were visible as not fully covered by soil (seeds are close to the

surface and watering uncovered them) and all them have sprouted, independently from the type

of soil. We're now looking forward to seeing which will grow further than what seed stocks

alone permit, and how growth rates will differ. Chards have not shown any sign of activity

yet, consistently with their expected time-to-germination (>=3d).

A slight green cloud is now visible above the regolith layer in the cyanobacteria's culture

bottles. They have recovered from the airplane trip, in spite of the cold temperatures, lack

of illumination and absence of nutrients (as no centrifuge is available here, I washed cells

beforehand and resuspended them in saline solution).

I Joined today's EVA for sampling. Even though a mechanical problem prevented me from

collecting as much samples as I planned, I collected 3 which I'm looking forward to analyzing

in my home lab.
