3. Consumables – HAB1 Nominal amount for Earth to Mars transit
After mission abort – hygiene water reduced to 10 kg/person/day
Reduces weight by 3500 kg while maintaining crew health

4. Consumables - ERV Accounts for nominal consumables for entire 230 days
An extra 99.2 kg and .85 m^3 of food needs to be added when CTV docks with ERV for Mars to Earth transit

5. Consumables - CTV
The Consumables for the CTV include enough food, water, and oxygen for 7 days with no recycling capabilities

6. Life Support2
Life Support Systems are composed of physical-chemical processes
Both the HAB and ERV incorporate the same life support systems and specifications

7. Total Mass/Volumes3 HAB – 11450.8 kg / 32.68 m^3
ERV – kg / m^3
CTV – kg / .40 m^3

8. Power4
Due to the recycling process of the consumables, these power constraints are critical to the survivability of the crew

9. In - Situ
The In–Situ production plant needs to have the capability to produce 3476 kg of water and 32 kg of oxygen
These consumables account for the stay on the planet not brought due to the lower amount of hygiene water given to the crew for the free-return

10. Schedule
24.5 hour day
This would be a very flexible schedule but average day on the job
2.5 hours of com gives 1.5 of business and 1 of personal

11. Medical Mainly focused on trauma, injury, or illness
Not focused on disease
Examples
First Aid (bandages, etc)
Burn treatments, bone/muscle injuries
Pain medications, common illness medications
Equipment

12. Work in Progress Sizing incorporated with layouts
Thermal Control around Venus
