Science Operations: The third of the scientific EVAs was scheduled for the afternoon work period. This involved driving to site #2 at Tank Wash and continuing setting out the 100 square metre (100 1m x 1m plots). During the 2 hour EVA, setting out of the grid was completed and the first samples collected. This involved hovering the heavy duty magnet just above the ground surface and systematically ‘sweeping’ it across the 1 square metre of the plot. Two plots were sampled and very fine magnetic particles were recovered from both plots!
On the return to the hab, the Cactus Road #1 site was revisited to allow another crew member an opportunity to operate the heliograph. With line of sight radio communications established, the heliograph was successfully operated and video records collected.
Tabulation of the baseline food stock macro and micronutrients for the waste study is being updated with the arrival of further supplies. Closed Loop Food Waste Study: The day’s waste for Sol 5 is: 108 grams; consisting of 383 calories, 6g fat, 3g saturated fat, 176mg sodium, 53g carbohydrates, 4g fibre, 3g sugar, 24g protein. The bread production errors were turned into tasty crackers/cookies (#nowaste).
Additional Activities: Nil.
