1. The Mission to Colonize Mars
A home away from home…
(Yes, I know there aren’t oceans on
Mars, but come on…the background
looks cool)
2. Outline
• Introduction
– Background information
• Why do we want to try this?
• How do we plan on getting there?
• How do we make it inhabitable?
• Is it possible? Will it happen?
• Conclusion
3. Introduction
• Originally observed as a red star –
represented evil and war
• Became the focus of science
fiction
– Stimulated public interest
• Mariner 3 sent to Mars – 1964
• Viking landers map surface – 1975
– No evidence of life
• Mars pathfinder – 1997
• Meteorite from Mars – signs of life

4. Why do we want to try?
• Earth may someday become uninhabitable
– Overpopulation, resources, environment
• Information about the universe and life
– Implications on our place in the universe
• Larger frontier and different environment
• Developments that may change the way we live
• Symbolism of the advancement and cooperation of
mankind
• Job opportunities and global economy
5. How do we plan to get there?
• Need: way to get there, place to stay, way
to get back
– Fuel, food, air
• 1st year: Send 1 or 2 unmanned ships
– MAV(Mars Ascent Vehicle), ERV(Earth
Return Vehicle), and an unmanned
habitat
• 3rd year: Send 1 or 2 unmanned, 1 manned
– Same first ships, last contains four
astronauts
• 5th year and every odd year after: repeat
– Continuous habitation on Mars
• MAV produces it’s own fuel from the
atmosphere (Carbon Dioxide and Hydrogen
-> Methane)
• Other options: Brute force (one huge ship
with everything), one-way trip (astronauts
never return)

mars discussed (Orbital Rendezvous
with in-situ (on site) propellants ).
6. How can Mars become habitable?
• Problems:
– Only known water sources in ice caps and permafrost beneath the
surface
– Cannot breathe in current atmosphere
– Weather is much too harsh (average of -60 degree Celsius
temperature, for example)
• Solutions:
– Release manufactured greenhouse gases
• Temperature raises to 0 degrees Celsius and higher
• Frozen carbon dioxide sublimes to gas, increasing pressure and raising
temperature
• Water melts, causing a hydrological cycle
– Microbes released to form a biosphere and produce oxygen
• Moss and plant life begins

7. Is it possible, and will it happen?
• Based on current ideas and research, it is highly
possible.
• Opposition in the form of cost, purpose, and risk.
– Originally estimated at $450 billion, now estimated
between $20 - $50 billion for three missions.
– Can make it significantly less risky by use of in-situ
propellant and orbital rendezvous.
• Plan on making manned-missions
– http://mars.jpl.nasa.gov/mer/mission/timeline.html
for timelines and information
• Some say it will take no more than 100 years to
terraform, some say almost 1 million. Either way, it will
probably be several decades from now, at least, before
we might begin.
8. Conclusion
• Colonization of Mars is
certainly possible, and
definitely a consideration for
the future.
• There are many reasons for
colonizing Mars, some very
practical.
• Though colonization will not
likely be seen in our lifetime,
the future could hold a new
Earth-like planet, colonized the
surface-over by humans.
