spreading life throughout the solar system
"I want Americans to ... push out into the solar system
not just to visit, but to stay." Barack Obama, U.S. President,
in the 2015 State of the Union address to Congress.
A billion years ago there was no life on land. In a phenomenal
development, by 400 million years ago land life was well
established. We are at the very beginning of a similar, perhaps
even more important, development. Today Earth teems with life, but
as far as we know, in the vast reaches of space there are only a
handful of astronauts, a few plants and animals, and some bacteria
and fungi; mostly on the International
Space Station. We can change that. In the 1970's Princeton
physicist Gerard O'Neill, with the help of NASA Ames Research
Center and Stanford University, discovered that we can build
gigantic spaceships, big enough to live in. These free-space
settlements could be wonderful places to live; about the size of a
California beach town and endowed with weightless recreation,
fantastic views, freedom, elbow-room in spades, and great wealth.
Subsequent discoveries have brought this dream much closer.
In time, we may see millions of free-space settlements in our solar
system alone. Building them, particularly the first one, is a
monumental challenge. If this sounds exciting, read on.
- Who? Pioneers at first,
billions of ordinary people later.
- What? Very large to gigantic rotating,
pressurized spacecraft the size of towns or even cities.
- Where? In orbit; near
Earth at first.
- How? Solar energy, lunar
and asteroidal materials, and lots of hard work.
- Why? To
Survive and Thrive.
- When? Good question, when
do you start working on it?
National Space Society Space Settlement Contest
This annual space settlement design contest for
6-12th grade students has been sponsored by NASA Ames Research Center from 1994-2018, for the last several years in conjunction with the National Space Society (NSS). A Space Act Agreement between NASA and NSS is currently being worked on to continue joint sponsorship of the contest. Meanwhile, the 2019 contest is being sponsored by NSS.
