EVA Report – May 10th

Crew 212 EVA Report 10-MAY-2019

EVA #06

Author: Zoe Townsend

Purpose of EVA: First testing of drones and soils collection

Start time: 15:00

End time: 17:00

Narrative:

Today’s EVA was to run two simultaneous experiments. The first experiment was to collect sand and rocks from various points of interest around the Hab. This is combined with the soil (red clay) collected in EVA #4. This soil, sand and rock solution will be mixed with the bacteria from radioactive regions to help with plant growth.

The second experiment was the continuation of the Drone testing, The X-5 and Tarot were tested today, the Tarot was flown around the Hab at different points that were identified as points of interest in EVA #4. Cameras on board took videos of the flight until battery issues prevented further flying. Secondly, the X-5 was flown in an empty area north of the observatory, the flight was sustained but cut short after a maneuver caused an unplanned landing.

Notes from the debriefing:

· Bring water

· Ensure that all the roles are fully defined prior to the start of the EVA

· Standardize the depressurizing time of the EVA (3 mins)

· Ensuring that there is confirmation from the Hab prior to search and recover of Drone.

EVA Report – May 10th

Crew 212 EVA Report 10-MAY-2019

EVA #05

Author: Marlen Castillo Vilcahuaman

Purpose of EVA: Locating the Martian flora according to Paul Sokoloff’s study, to obtain their soil for the study of microbiological diversity in desert soils. We’ll take photos of the flowers, characterize and pick up their soil.

Start time: 10:30 AM
End time: 11:30 AM

Narrative:

The purpose of this EVA was to find the Martian flora registered in Sokoloff’s paper. Although we have no work in plant ecology for this mission, we thought soil samples from flowers would have an interesting diversity in microbes, which would mean more morphological diversity in the petri dish. We asked for two rovers (Spirit and Curiosity).

However, the LA Times visit altered our plans. We took Opportunity too so that they could come with us and watch our fieldwork during EVAs. Our final point was Sector12S Northern 4250933, Eastern 518167. But we had problems with Spirit. Just after turning in Galileo Road 1104, one of our crew members reported that Spirit was with 70% of battery.

We were surprised by this battery usage. Hence, we decided to stop at that point (12S 518779.59 m E 4251383.04 m N) and do our recollection work, collecting soils and flowers and doing some photography of them. After 20 minutes of walking and going around the field in search of flowers, we decided to turn around and go back to the Hab.

Spirit arrived at the Hab with 58% of battery. Curiosity’s return was nicer, with its battery being higher than 60%.

We collected four soil samples, identifying them per plant.

Destination: URC North Site and continuing in the first part of the road on the east.

Greenhab Report – May 10th

Crew 212 GreenHab Report – 10-May-2019: SOL 5

GreenHab Officer: Hector Palomeque

Environmental control: Ambient with the door open from 07:00 to 14:30 + door closed from 14:30 to 15:30 + door open from 15:30 to the rest of the day

Shade cloth 80%: on

Average temperatures:
Low: 15.0 °C (±0.85)
High: 32.7 °C (±1.70)

Hours of supplemental light: 0

Daily water usage for crops: 5 gallons

Water in Blue Tank: 157 gallons

Time(s) of watering for crops: 12:00

Changes to crops: All plants look healthy. Half of Basil plants have already bloomed. Tomatoes in the wood table (black pots) still blooming. Tomatoes in the blue tray have already started fructification (1 tomato).

Narrative: The GreenHab door had to been closed at 14:30 due to the rain and then re-opened at 15:30 because the weather has changed dramatically. Plants were watered just once at noon. The usual watering at early morning (at 07:00) was avoided due to the substrate has remained moist since the day before.

Some herbs and Chard were harvested for preparing the lunch of the Crew.

Harvested: 100g Chard + 5g Parsley + 6g Basil

Support/supplies needed: None.
