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.

Science Operations: The second of the scientific EVAs was scheduled for the morning work period. This involved driving to site #2 at Tank Wash and establishing a 100 square metre (100 1m x 1m plots) on a relatively undisturbed natural surface. During the 2 hour EVA, the outline of the grid was established and three east-west delineators positioned. The task is incomplete.

A secondary experiment involved testing the magnetism of material brought to the surface at an adjacent anthill. Though it was hypothesized that this material might contaminate the sample plots; there was zero evidence of magnetic material at the surface.

A tertiary experiment was conducted at the Cactus Road #1 site before the return to the hab. With line of sight communication possible, a heliograph was used to demonstrate an emergency communications method should voice contact fail. The demonstration was successful and video records collected.

Tabulation of the baseline food stock macro and micronutrients for the waste study was completed.

Closed Loop Food Waste Study: The day’s waste for Sol 4 is: 229 grams; consisting of 891calories, 15g fat, 9g saturated fat, 1533mg sodium, 126g carbohydrates, 8g fibre, 4g sugar, 42g protein. Waste was significantly larger due to bread production errors. Otherwise, less waste is generally produced at breakfast, with almost all occurring at lunch or dinner, depending on the type of food cooked. The majority is preparation waste with no spoilage waste to date and a small amount of plate waste.

Additional Activities: Reinforcing the coverings for the tunnels continued throughout the day as time became available.

Science Operations: The first of the scientific EVAs was scheduled for the afternoon work period. This involved a 2 hour traverse in the rovers to Tank Wash and south of the Galileo and Cactus Road junctions. At both these locations, relatively flat relatively undisturbed areas were identified and GPS surveyed and photographed so that a 10 square metre grid could be deployed from which samples targeting mircometeorites would be collected.
In preparation for the sampling, during the morning work period, the Science Dome’s large open area was utilized to construct the 1m x 1m grid square boundaries in readiness for deployment.
Concurrent with the preparations for micrometeorite samplings and EVA, tabulation of the baseline food stock macro and micronutrients was undertaken for the waste study.
Closed Loop Food Waste Study: The day’s waste for Sol 3 is: 89 grams; consisting of 293 calories, 1g fat, >1g saturated fat, 555mg sodium, 65g carbohydrates, 6g fibre, 31g sugar, 10g protein.
Additional Activities: Reinforcing of the coverings for the tunnels was undertaken throughout the day as time became available.

Science Operations: Weather conditions prevented EV activities during the morning, so all crew underwent instruction in donning and doffing both the exploration and two piece suits. In the afternoon, EVAs were approved and two short training activities were carried out. All crew have now become familiar with the operation of both types of suits, hab egress and ingress, operations with rovers and mobility on the surface.

Closed Loop Food Waste Study: The day’s waste for Sol 2 is: 89 grams; consisting of 339 calories, 10g fat, 5g saturated fat, 1619mg sodium, 56g carbohydrates, 3g fibre, 10g sugar, 5g protein.

1. EVA Suit Maintenance: The hab has been set up following arrival. All backpacks have been plugged in and fully charged. Helmets are clean and contained in their cloth bags except for one helmet, for which, the cloth bag is missing. Radios have been tested and are fully charged. Communication earpieces remain to be tested for faulty performance.

2. Green Hab: The green hab has been activated and is awaiting water and additional soil base before sowing of this seasons crops.

3. Astronomy Dome Operations: No astronomical observations have been planned for this crew rotation.

4. Science Dome Operations: The Science Dome has been activated and is awaiting EVAs for sample acquisition and sample testing.

5. RAM Operations: The RAM Dome has been activated and is ready for contingencies.

6. EVA: No preparations or activities have been undertaken to date. The access routes have been identified to allow sample locations to be identified.

7. Closed Loop Food Waste Study: This study has been initiated and is ongoing. Day’s waste: 79g; consisting of 323 calories, 10g fat, 5g saturated fat, 1179mg sodium, 52g carbohydrates, 7g fibre, 6g sugar, 7g protein.

8. Additional activities: Nil
