Yesterday Sunday we did another EVA in the late morning. Annie and I testes again the equipment from Swamp Works in order to test soil resistance. Then we did some photos and movies for public outreach and social media.
Since this morning, my seeds are sowed in their small sealed germination box, where humidity is as high as possible for optimal germination. We have three types of lettuce (Waldmann’s Green, Salanova et Outredgeous), two types of radish (Pink Beauty et Rudolf), some cherry tomatoes Micro-Tina and Earligreen Peas. But above all, tomato seeds which spent 6 years aboard the satellite LDEF from 1984 to 1990!! We also have seeds of the same tomato variety which flew aboard Space Shuttle Atlantis on mission STS-86.
I got these seeds thanks to the company ORBITEC, who also lent me the “Biomass Production System for education (BPSe)” precursor of the Veggie which will soon fly aboard the International Space Station. This system is located in the main room of the habitat and will help me evaluate the impact of plants on the moral of the crew.
My first experiment focuses on the effect of different wavelengths on plant growth and the engineering challenges associated with the different lamps. For this experiment I will only grow lettuces and radishes.
In the afternoon, Tiffany and I built shelves above the washing-machine in order to have more storage room in the kitchen. We are pretty proud of the result.
