Before you pitch your tent you might want to know more about the place you are going...

Biosphere 2 1991- 1993 (present)
1/3 of the gravity very cold temperatures very little air pressure
Will this work?
What are you going to do for food?
Current • Resupply from Earth • Physical-chemical systems
Food Oxygen Carbon dioxide removal Water
$50,000 per kilogram
Oxygen = 0.75-1.0 kg/day*
Water = 3.0 kg/day* (recycle)
Food = 0.5-0.6 kg/day*
Crew = 6
Food/Oxygen = 9.6 kg/day
Trip duration = ~2 years
Total Food/Oxygen = 7008 kg
Average elephant = 2300 kg
Cost just for food = $ 350 400 000**
* statistics based on a 70 kg (154 lbs) person
** does not include cost of food
Is there a better way to get food, oxygen and water while living on Mars ?
• Food Production
• Carbon Dioxide Absorption
• Oxygen Generation
• Water Recycling
• Waste Degradation

Martian Agriculture Recall that Mars has very low temperatures and little atmospheric pressure. How would you grow plants?
In a greenhouse.
Woohoo! A greenhouse on Mars!
• Can use ambient light
• Warmer environment
• UV protection
• Weather Protection
–Wind
–Dust storms
• Increased pressure
• Increased humidity
Radishes
Ambient – 100 kPa 66 kPa
33 kPa 10 kPa
