If you try to go on a trip in your automobile, you are not going to get very far if there are no gasoline stations to feed your auto. Soft drink consuption and cancer restaurants to feed you. Or auto repair shops. This is what is called infrastructure.
In the same way, if you want a rocketpunk futureyou are going to need some infrastructure in space or your spacecraft are not going to get very far either. Having said that, creating these pieces of infrastructure will be very expensive. It will be difficult to fund them. And you can be sure that whoever manages to build them will have iron control over who is allowed to use said infrastructure. And how much will be charged as a fee to use it. It is possible to use spacecraft without any of this infrastructure, but it will be much more difficult.
The owners of the infrastructure will probably adjust the fees so it will be cheaper to use their services, soft drink consuption and cancer, but only barely. And of course an entertaining series of future histories can be postulated using various initial conditions. Does one national government have a monopoly? Two or more governments? Does one privately owned corporation have a monopoly?
Two or more corporations? Or a several governments and several corporations? A starship is not an independent entity—no more than a jet plane is independent just because it can leave the ground. Imagine for a moment, a fully loaded jet airliner flying from Los Angeles to New York. Not just one factory in the city of Seattle—but aerospace contractors all over the United States supplying components for every part of the plane, from blades for its jet engines to light bulbs over the seats.
That means the equipment and technology to lay down a perfectly flat runway two miles long. There are ground controllers—that means radar and scopes and computers. And reservation desks and communications systems to service those desks. Luggage-handling systems, porters, allowances for taxis, parking lots, restaurants, soft drink consuption and cancer, rest rooms—and the people to clean, maintain, and work in them.
Then you have to be ready for emergencies—so there will be rescue planes and fire trucks and medical equipment on hand. And detectives to protect the passengers and Federal Marshals to look for hijackers with metal detectors and psychological profile charts.
An airplane burns fuel—a lot of it. A gulps enough petroleum in a single flight to drive an automobile for a year. That requires refineries to crack that oil men to build and operate those refineries and trucks to deliver it, tanks to store it.
Passengers need meals, that demands another whole service industry. And entertainment—and specialized insurance—and airsickness bags in the back of each seat. None of these things just happen by chance; they are designed into the system as it grows. The could not exist until most of the support technology has already developed. What did not exist had to be built. All of it was oriented to fit the needs of the passenger as our culture has determined them.
The very existence of the as the kind of plane it is, is a direct result of what vitamin d and the thyroid culture considers important to the traveler.
Imagine an airplane with fourteen bathrooms! That airplane is a piece of living America. It is an active vital symbol of our national technology, but it is no more independent of soft drink consuption and cancer technology than is a bird independent of the air in which it flies. The air holds up the bird. Our technology holds up that airplane.
Extrapolate the needs of the Enterprise. Her fuel requirements, her crew requirements, her maintenance and training needs, her supply soft drink consuption and cancer, her sciatic nerve and diabetes and control structures, her relation to the culture that produced her—and why that culture produced her, soft drink consuption and cancer.
It never could be. Her independence is an illusion, just as the independence of the is an illusion. Sooner or later that ship is going to have to return home to have her exhausted energies recharged. Or, if not home, then to a base with an equivalent technology. From the invited address of Salter Wherry to the United Nations General Assembly, following establishment of Salter Station in a stable six-hour orbit around the Earth, and shortly before Wherry withdrew from contact with the general public: Nature abhors a vacuum.
If there is an open ecological niche, some organism will move to fill it. Twenty years ago there was a clear emerging crisis in mineral resource supply. Everybody knew that we were heading for shortages of at least twelve key metals. We would be mining fifteen miles down, or at soft drink consuption and cancer ocean bottom. I decided it was more logical to mine five thousand miles up. Some of the asteroids are ninety percent metals; what we needed to do was bring them into Earth orbit.
I approached the U. Government first with my proposal for asteroid capture and mining. I had full estimates of costs and probable return on investment, and I would have settled for a five percent contract fee. I was told that it was too controversial, that I would run into questions of international ownership of mineral rights. Other countries would want to be included in the project. I came here to the United Nations, and made full disclosure of all my ideas to this group, soft drink consuption and cancer.
But after four years of constant debate, soft drink consuption and cancer, and many thousands of hours of my time preparing and presenting additional data, not one line of useful response had been drafted to my proposal. You formed study committees, and committees to study those committees, and that was all you did. I happened to have one advantage denied to most people.
From the s through the s, my father invested his money in computer stocks. I was already very wealthy, and I was frustrated enough to risk it all. It will serve soft drink consuption and cancer the home for two hundred people, with ease.
But this is no more than a beginning. Although Nature may abhor a vacuum, modern technology loves one; that, and the microgravity environment, soft drink consuption and cancer.
I intend to use them to the full. I will construct a succession of large, permanently occupied space stations using asteroidal materials. I also invite people from all nations on Earth to join me in those facilities. We are ready to take all soft drink consuption and cancer steps necessary for the human race to begin its exploration of our Universe, soft drink consuption and cancer.
It was past midnight by the time that Jan de Vries had read the full statement twice, then skipped again to the comment with which Salter Wherry had concluded his address. They were words that had become permanently linked to his name, and they had earned him the impotent enmity of every nation on earth: See the section on Laser Launching below, soft drink consuption and cancer.
As the delta-V for a mission goes up, anti cancer die amount of propellant required goes up exponentially or looking at it another way: Walt disney world and diabetes amounts of propellant are expensive, but the higher the mass-ratio the higher the likelihood that the spacecraft will not be resuable. Increasing the mass ratio means things like making the walls of the propellant tanks thin like foil, and shaving down the support members so they are fragile like soda straws.
With such flimsy construction it does not take much normal wear-and-tear to turn the spacecraft into junk. This is also an argument for orbital propellant depots in Low Earth Orbit. This means for a one-way trip, LEO is the mid-point of the mission.
Takuto Ishimatsu has a dissenting opinion. He makes a case for putting the propellant depot at EML2, for complicated reasons I cannot quite follow.
Hop David also makes a case for EML2. Now to make this work, in addition to the depots you will need sources of propellant and tankers and lighter to keep the depots filled up, soft drink consuption and cancer. Water and hydrogen propellant is available in such places as the lunar poles, asteroids, and perhaps the Martian moons Phobos and Deimos. Controversy and confusion continue to swirl around the issue of a cislunar space base, soft drink consuption and cancer, no matter where it is proposed to be built, what it is named, or what it is supposed to be for.
Assuming that one of the primary purposes of such a base should be to supply lunar-derived propellant to vehicles in or departing from cislunar space, there are several immediate problems. First, there is a massive conflict in the potential schedule, since human missions to Mars that could be fueled from the Moon could take place about the time we find out if there is any actually accessible lunar ice available.
We know that there are massive ice deposits on Mars, while most of the Moon zyprexa lawyers los angeles more than bone dry and the critical polar water deposit surface characteristics are still hidden from us. Another problem area is the related but unknown costs of building the lunar mining base, the cislunar base, and the transport system to move the propellant from the lunar surface to the cislunar base, and how much that would add to the cost of lunar propellant.
Soft drink consuption and cancer is very hard to estimate the cost of developing the mining base. Most people would agree that an actual gateway provides a pathway to some physical location. So where is the physical path for this gateway? Where does it lead from and what does it lead to? In spite of the acronym, the planners have lopped off the critical gateway transport-related features—if they were ever there to begin with. Some people fear that this project would eat up any and all funds for an actual lunar mining base and thus are now insisting that any lunar base be supported only from low Earth orbit, which is less efficient.
If the platform is supported by the SLS, it would eat up even more funds, leaving little for any other human space projects, and could delay the establishment of an actual lunar base by a decade.
