Crew 214 Science Report 2Nov2019
SOL: 6
Crew 214 – Expedition Boomerang Crew
Submitted by Science Officer Andrew Wheeler
Science Operations: Preliminary viewing, through the binocular microscope, of the particles recovered from yesterday’s EVA clearly showed the morphology of the particles and that some were spherical, however positive identification of micrometeorites could not be confirmed.
The fourth of the scientific EVAs was scheduled for the afternoon work period. This involved driving to site #2 at Tank Wash and continuing sample collection from the 1m x 1m plots. During the 2 hour EVA, 10 samples were collected and all appear to contain magnetic material.
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 newly arrived food stock macro and micronutrients for the waste study was completed.
Closed Loop Food Waste Study: The day’s waste for Sol 6 is: 15 grams; consisting of 44 calories, 1g fat, >1g saturated fat, 16mg sodium, 7g carbohydrates, 1g fibre, >1g sugar, 6g protein. At the end of the first week of the rotation, over 613 grams (2791 calories) of food have been wasted at a rate of approximately 400 calories per day, or 10 grams per person per day. This waste was proportionally derived from carbohydrates (63%), protein (15%) and fats (22%), which was a slight shift from the macronutrient ratios of crew stock inventory from the start of the rotation (C58%, P12%, F31%).
Additional Activities: Tidying and cleaning chores around the hab.
