Our second day in the Mars Desert Research Station was excellent. We had a long briefing session this morning to discuss the different EVA expeditions that are planned for this week. We also decided to go for what Nancy called the Spanish schedule, that is, delaying all our external EVA activities until after four o’clock to avoid the burning afternoon sun. Actually, the temperature differences in the desert are quite marked: the highest temperature was 32 deg. C at 12:38 pm and 4 deg. C at 5:20 am. The task for the first EVA of this rotation was to set-up the station greenhouse and to plant the various seeds that we want to observe. We have four kinds of seeds: radishes, Alfa Alfa sprouts, arugella salad and tatsoe cabbage.
