Dare Mighty Things -- Curiosity Landing Procedure

Just imagine you're a Martian for a minute. You're standing out in your yard, and this... "thing" drops out of the sky on a tether.

I'm looking forward to seeing how this thing works on August 5th.

High Frontier

The High Frontier, Human Colonies in Space, by Gerard O'Neill.
Depiction of "Island Three" concept, a 3km radius cylindrical space habitat.
Last year the Students for the Exploration and Development of Space (SEDS) gave out several copies of The High Frontier by Gerard O'Neill to its Chapters, including Iowa State Space Society (I triple S). Somehow I ended up with a copy. The book was originally published in 1976 and therefore contains some hilarious estimates of time scales and costs, particularly for nearer term projects that are already completed such as the Space Shuttle and International Space Station. I knew NASA was overoptimistic about the economic efficiency of the Shuttle, but I had no idea they were expecting 50-100 flights per year at a cost of $20 million per flight!

Without all the red-tape, setbacks, disasters, and other unforeseen complications, the original concept for the Shuttle indeed was simple enough to be inexpensive access to LEO.

What is now known as the ISS was discussed in the book as a "workbench" in space, and the real construction efforts would be for Island One, a giant space habitat longer than three Empire State Buildings. The hilarious part is that he predicts conservatively that Island One could be built by 2010, which more or less corresponds to the completion of the ISS. Technically, it is completely feasible, perhaps even economically. However, he accurately identifies one of the biggest variables that is nearly impossible to predict, which is the politics behind the development of space.

There are many cool ideas throughout the book, and it is an inspiring picture of the future. But I also imagine that human colonies in space could lend themselves easily to "dystopic" scenarios. Such is the theme of my most recent novel, written last November, entitled "Supervessel." Currently I don't like my story at all, and it needs a lot of reworking.

I do believe that if the world can remain somewhat stable in the coming future that human colonies could be developed in space within my lifetime. However, while the technical details can easily be worked out on paper, the political and economic stability of the globe will play an important part in whether or not we permanently get off the ground.
