The Antarctica Model
Fifty years of continuous operations, 1-15 month
tours. Three permanent bases with temporary field
camps. Dec 1956 Bases established, IGY Cold
War competition. Science exploration was
rationale, NSF had responsibility for
science. 1970s, 1980s US Antarctic research
program operated as a part of foreign policy
military preparedness for cold weather
operations. 1990s Cold War ends, military
activities in USARP reduced. 2000 Helicopter
transport provided by private sector. 2005
Civilian science (NSF) managed program entirely.
Contractor operation of base (Ratheon Polar
Services) Air Force provides transport to
Antarctica, Coast Guard provides ice
breaker. 2006 NSF directed to assume operation
of ice breakers.

Dont send humans because they will contaminate
Mars before we have a chance to determine if it
has life and its potential for life

Weve already contaminated Mars
