Stepping Stone
The ISS should be used as a global first step towards follow-on space endeavors:
(i.e. Module design Test beds, Space tourism , Co-orbiting stations, Moon vacations, etc. )
The current features and resources of the ISS need to be utilized to the fullest extent possible to maximize the international investments already made, and global investments being actively sought.
ISS Features:
Estimated ISS Cost: $35-160 Billion
De-orbit timeframe:
ISS life extended through 2020 and conceivably to 2025 or 2028
Concept Overview
Assumptions:
Concept execution is dependent on the use of existing or nearly completed technology with only minor updates
Expected Execution Time Frame: 2015-2017
Use Bigelow Inflatable space modules to expand the ISS. Two segments will be added:
Crew Habitat test bed for future space hotel designs
Dedicated Earth Observation & Hardware testing laboratory
Bigelow Modules (BM)
BA 330 Specifications | |
Crew | 6 |
Launch | 2014 or 2015 |
Mass | 23,000kg |
Length | 14 m (45 ft) |
Diameter | 6.7 m (22 ft) |
Pressurized Volume | 330 m3 (12,000 cu ft) |
High module maturity, availability for testing in 2014/2015 timeframe, & potential cost savings make BM a viable near term option
High TRL:
Interface Compatibility:
Cost Comparison:
* Price Included US support of the Soyuz 2

Crew | 3 |
Launch | 2014 or 2015 |
Mass | 8,618.4Kg |
Length | 8.7 m (28.5 ft) |
Diameter | 6.3 m (20.7 ft) |
Pressurized Volume | 180 m3 (6,357 cu ft) |

History of LEO Space Station Earth Sensing
Low ISS Altitude resulted in an improved Spatial Resolution
Current Remote Sensing Efforts
Despite current efforts the ISS is not being fully utilized for Earth Remote Sensing

ISS Earth Observation Lab can be linked to existing meteorological or EO S/C in GEO for enhanced data sets.
ISS Earth Observation Limitations
51.6°
Economical Advantages
Mission | Cost | Launch Year |
GEOEye -1 | $478.3M | 2008 |
GEOEye-2 | $750-800M | 2013 |
GOES I-M * | $1,241 M | 1975-2010 |
EOS Aura* | $707.6M | 2004 |
ICESat* | $177M | 2003 |
CloudSat* | $105M | 2006 |
LandSat TM (7) | $ 800M | 1998 |
In cases where the ISS orbit limitations can be overcome it may be more economical to use the ISS as a instrument platform and avoid the high cost of a GEO Spacecraft
