The Case for Colonizing Mars, by Robert Zubrin lesforgesdessalles.info mars/lesforgesdessalles.info 1 of 4. 05/01/08 AM. Home. Many of the ideas were developed at the Case for Mars II workshop, July , , V. Mars Base Establishment: Baseline Mission Plan. Question: How much rope is needed to connect two posts separated by a distance of 10 meters? In principle, it can take any amount: But it can be done with.
It covers his involvement in robotic space exploration from his initiation in on the NASA Genesis probe to the joyous moment when Curiosity zapped its first rock in early Not Earth as well as virtual experiences. Amazon Drive Cloud storage from Amazon. Zubrin suggests three models to provide the will and capital to drive Mars exploration forward: It is evolving circumstances. Robert Zubrin. The Case for Mars acknowledges that any Martian colony will be partially Earth-dependent for centuries.
The first stage of the ITS towers The second stage is On September 29th, , at the International Astronautical Congress in Adelaide, Australia, Musk provided an update to his presentation regarding the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars.
This entire minute presentation is provided below:. The Mars Direct scenario held potential of lowering costs and of bringing the human exploration and settlement of the Red Planet into the realm of feasibility.
The Mars Direct scenario lowered cost in two key ways: Zubrin describes his ideas quite effectively in the following three articles he wrote for the NSS magazine, Ad Astra:. The Promise of Mars. The Case for Colonizing Mars.
The Significance of the Martian Frontier. The Case for Mars: The Free Press. Carl Sagan wrote: Workman Publishing. Profusely illustrated.
Access to Mars , by John K. The Case for Mars is, according to Zubrin, a comprehensive condensation for laymen of many years' work and research.
Chapters one and four deal with Mars Direct most completely. For Robert Zubrin , the attractiveness of Mars Direct does not rest on a single cost-effective mission. He envisions a series of regular Martian missions with the ultimate goal of colonization, which he details in the seventh through ninth chapters. As initial explorers leave hab-structures on the planet, subsequent missions become easier to undertake.
Large subsurface, pressurized habitats would be the first step toward human settlement; the book suggests they can be built as Roman -style atria underground with easily produced Martian brick.
During and after this initial phase of habitat construction, hard-plastic radiation - and abrasion-resistant geodesic domes could be deployed on the surface for eventual habitation and crop growth.
Nascent industry would begin using indigenous resources: The larger work of terraforming requires an initial phase of global warming to release atmosphere from the regolith and to create a water-cycle.
Three methods of global warming are described in the work and, Zubrin suggests, are probably best deployed in tandem: While the work of warming Mars is on-going, true colonization can begin. The Case for Mars acknowledges that any Martian colony will be partially Earth-dependent for centuries. However, it suggests that Mars may be a profitable place for two reasons. First, it may contain concentrated supplies of metals of equal or greater value to silver which have not been subjected to millennia of human scavenging and may be sold on Earth for profit.
Secondly, the concentration of deuterium — a possible fuel for commercial nuclear fusion — is five times greater on Mars. Humans emigrating to Mars thus have an assured industry and the planet will be a magnet for settlers as wage costs will be high.
While detailing the exploration and colonization, The Case for Mars also addresses a number of attendant scientific and political factors. The fifth chapter analyzes various risks that putatively rule out a long-term human presence on Mars.
Zubrin dismisses the idea that radiation and zero-gravity are unduly hazardous. He claims that cancer rates do increase for astronauts who have spent extensive time in space, but only marginally. Back-contamination — humans acquiring and spreading Martian viruses — is described as "just plain nuts", because there are no host organisms on Mars for disease organisms to have evolved.
In the same chapter, Zubrin decisively denounces and rejects suggestions that the Moon should be used as waypoint to Mars or as a training area. It is ultimately much easier to journey to Mars from low Earth orbit than from the Moon and using the latter as a staging point is a pointless diversion of resources.
While the Moon may superficially appear a good place to perfect Mars exploration and habitation techniques, the two bodies are radically different. The Noon has no atmosphere, no analogous geology and a much greater temperature range and rotational period.
Antarctica or desert areas of Earth provide much better training grounds at lesser cost. In the third and tenth chapters, The Case for Mars addresses the politics and costs of the ideas described.
