NOAA CONTRACT
The National Oceanic and Atmospheric Administration (NOAA) awarded
the SSI team a contract in September 2005 to analyze the potential
for next generation micro satellite and propulsion technologies,
provided on a commercial “data buy” basis, for increased
working times in solar storm forecasting and other government
telecommunications needs.
By March 2006, the SSI team developed conceptual designs for
a unique, solar sail powered telecommunications deep space platform
that can provide services for both governmental and commercial
customers. Two of the designs call for the placement of a platform
at a location between the Earth and the Sun that, compared to
the existing SOHO and ACE spacecraft, would provide much earlier
warning of solar storm activity that could disrupt power and communication
systems on Earth and in space. A third design would be particularly
useful for relaying data from NOAA research stations in the Antarctic,
and for relaying data from future NASA missions to the Moon’s
south pole. Before flying any of these platforms, the SSI team
recommends that a technology demonstration platform be flown to
test the team’s solar sail technology – a new type
of spacecraft propulsion that has yet to be actually used in space. |

SPACE WEATHER
Space weather is the term used to describe the presence of energized
particles from the Sun (solar storms) that affect the performance
and reliability of both space-based and ground-based technologies
and systems. Solar storms can disrupt and damage satellites, cause
utility grid problems including blackouts, endanger astronaut
health and well-being, and – as recent experience during
hurricane Katrina showed - disrupt telecommunications, especially
emergency communications. |

REMOTE TELECOMMUNICATIONS
Planet Earth’s South Pole and the Lunar South Pole share
a similar challenge. Existing and planned human scientific bases
at both poles require high throughput and reliable telecommunications,
and are difficult to access with existing systems. The unique
vantage perspective provided by a solar sail enabled telecommunications
platform may provide a cost-effective, innovative solution to
multi-body polar communications. |
