Island Three - An Animation by Steve Gunn
A beautiful animation of an Island Three space colony. These are the truly massive habitats that Dr O'Neill describes in his works. This animation was created by the very talented Steve Gunn as part of Project SPACE.

Project SPACE
This is an update from
Project SPACE, the study project on Space Colonies being run by the British Interplanetary Society. We had a great
meeting recently and these are notes from it.
The meeting was about organising the study project in more detail and
deciding who is interested in tackling which part of the project. It’s a broad concept so there’s lots to get
stuck into!
We considered the
possibilities for space manufacturing on a colony and will be looking into the
revenue a colony could generate from this.
This might include synthetic biology, the processing of rare earth
metals and the creation of large industrial crystals for communication
satellites and x-ray crystallography, amongst other things. Carbon nano-tube and graphene production
might also be possibilities.

The creation of the large
space colonies proposed by Dr Gerard O’Neill and others has long been linked to
the manufacture of space-based solar power (SBSP) satellites and this was also
discussed. The current state of research
into this field was considered and SBSP is a sub-topic that is going to be
looked into as part of the project.
A space colony might also
be used as part of an infrastructure for the construction of other space craft,
both manned and unmanned. The use of a
colony as a “space dock” suggested an exciting vision in which space craft,
particularly for deep space exploration, might be constructed there. This might
lower the cost of space exploration as once such an infrastructure was in
place, the expense of transferring large amounts of mass from the Earth’s
surface would be greatly lowered and would in effect be limited to human
travellers and a few essential items.
Similarly, a space colony might serve as a centre for research for laser
propulsion space travel and also as the site for the laser.
This discussion about
possible forms of revenue involved a discussion about the economics concerning
the construction and operation of a space colony and we will be looking into
this as well. In considering the
economics of space colony construction we also discussed the relative merits of
using lunar material to build the colony with its attendant base and mass
driver in comparison to an alternative method of using asteroids for this
purpose. The use of an asteroid could
involve tunnelling into the body of a suitably sized asteroid and fashioning
the colony directly from its mass.
There are advantages in
this approach which might make it quicker and cheaper than the method set out
in The High Frontier and similar studies and this is one of the ways in
which the concept of a space colony needs to be updated from the studies in the
seventies. Using this method would
require surveying potential asteroids including both spectroscopic analysis and
sending probes to the asteroids for more detailed information. The composition of the asteroid would need
to be clearly understood. Use of
asteroids might in itself, because of the elements that might be found there,
raise the possibility of revenue from the raw materials.
In discussing these points,
it was interesting to have to hand a beautiful model of the asteroid Eros,
created by 3d printing. Eros is large enough to possibly form an Island Three space
habitat from! We also talked about making
contact with Deep Space Industries and Planetary Resources in this regard as
they are focussed on asteroid mining.

Other possibilities for
revenue from a space colony considered were that of being a holiday destination
and even as a tax haven.
We are also going to be
looking into human health issues such as whether a slightly lower
pseudo-gravity of say 0.8g might be used.
Issues concerning diet and the provision of medical facilities are also
to be considered. In particular we will
be looking at the ever present danger of radiation from cosmic rays and how the
colony would need to be shielded in some way from this.
The basic designs for the
colonies are going to be looked into as well including rethinking whether three
separate basic structures is a good idea or whether a more modular progression
in size would be a better idea. We are
also going to be looking at the possible incremental progression of space
habitats from the size of the International Space Station to the size of Island
One. This could involve a habitat nicknamed during the course of our meeting as
“Island Zero” – a habitat smaller than an Island One made using the asteroid
tunnelling technique outlined above.
Reconsidering the essential spherical design inherent of Island One is
also another point to look at.
Building up to an Island
One, we looked at the restraint imposed in the initial studies of limiting the
overall budget to that of Project Apollo. We will also be looking into the
Kalpana One space habitat as a first step before Island One. Another point is looking into whether there
is a need for the Island Two design; is it an unnecessary side step on the way
to the large scale Island Three space habitat?
Another major point in
updating the original studies from the seventies is the greater sophistication
of robotic systems and we will be looking at how these might change the
construction and operation of a space colony compared to the original plans
especially in terms of time and expense.
We are also looking into
the possibilities for sponsorship for Project SPACE which would help pay for
talks on the subject, models and props, films and websites and printed
literature on the subject.
