This is the crack official rationalization of the crack official contention that the shuttle will be cheaper.
You can still maneuver "cross range"-several hundred miles north crack or south relative to your approach from the west.
They can explode; enough said.What if a billion dollar spaceship wipes out on a "routine" mission "commuting" to space with some puny little satellite?Arc lights gleam off its impossibly smooth surface.The spirit of '75 is great for satellite customers, crack since the cost of regular rockets is inflating right along with the rest of reality.Also listed in the calculation are six flights a year for communications satellites, like those made famous by Comsat, Inc.Then, fuel spent, it would shuttle circle back to land like an airplane.When Columbia's tiles started popping off in a stiff breeze, it occurred to engineers that ice chunks from the tank would crash into the tiles during the sonic chaos of launch: Goodbye, Columbia.Computers have never flown with the unpredictable combination of damaged crack tiles that a shuttle may experience.Then the empty fuel tank would tumble away, to burn up in the atmosphere.Mathematica estimated that, under certain conditions, an individual shuttle flight would have a direct cost (fuel, command salaries, sweeping the pad).4 million.It was supposed to be able to carry 65,000 crack pounds into a low orbit, launching due-east.They didn't crack talk much about "expanded horizons" back in 1972 when nasa was selling the shuttle as an economy move.Much cheaper than rockets, much more versatile, it is the key to the next phase of space exploration.By spring of 1969, Apollo's impending success seemed assured."We wanted to have only miniscule involvement with the rocket concept in the future Day says. These are alpha "safe life" numbers.
This January it asked for still another 300 million extra.
Bolts radio and hoses fastened, the shuttle spaceship, its fuel tank, and the boosters would blast off together from Cape Kennedy, a tremendous troika of manual power.
They user make the rest of the project look export good by comparison.
Now the Spruce Goose was trying to fly.
A shuttle launching 65,000 pounds due-east was supposed to have enough energy to lift 40,000 pounds over the poles.
The ground isn't coming up; some prankster from Hell is throwing it at you.
It's right here in the cost-cutting plan, right under "C"-"Commuting to space." from this link Gregg Easterbrook, a Washington Monthly contributing editor, is a senior editor for The New radio Republic.Suppose the shuttles fly 500 jogos sorties, as predicted, and cost 13 billion to build.After a polar launch from Vandenberg, it would not.For a time, engine progress looked so bleak that Congress convened a panel of National Academy of Science members to decide if the motors would ever work.That means, for instance, three communications satellites and the extra user boosters needed to push them to high orbits.
