Houston, Texas
covers about 600 square miles in area, and is also the largest city in the United States which does not have zoning laws. Houston is world renowned for its energy industry (particularly oil),aeronautics industry and ship channel. The Port of Houston is the second busiest port in the United States, fifth busiest in the world. Because of the economic trades, many residents have moved in from other U.S. states, as well as hundreds of countries worldwide. Officially, Houston has been nicknamed the Space City. "Houston" was the first word uttered on the moon, as Neil Armstrong reported back to NASA. It is known by the locals, however, as the Bayou City. (Other nicknames include "Clutch City", and "Magnolia City".) The city had placed an unsuccessful bid for the 2012 Summer Olympics.

Shuttle development

The shuttle program was launched on January 5, 1972, when President Richard M. Nixon announced that NASA would proceed with the development of a reusable low cost space shuttle system.

The project was already to take longer than originally anticipated due to the year-to-year funding caps. Nevertheless work started quickly and several test articles were available within a few years.

Most notable among these was the first complete Orbiter, originally to be known as Constitution. However a massive write-in campaign on the part of fans of the TV show Star Trek convinced the White House to change the name to Enterprise. Enterprise was rolled out on September 17, 1976 and later conducted a very successful series of landing tests which was the first real validation of the gliding abilities of the design.

The first fully functional shuttle orbiter was the Columbia, which was delivered to Kennedy Space Center on March 25, 1979 and was first launched on April 12, 1981 with a crew of two. Challenger was delivered to KSC in July 1982, Discovery was delivered in November 1983, and Atlantis was delivered in April 1985. Challenger was destroyed in an explosion during launch in January 1986 with the loss of all seven astronauts on board, and Endeavour was built as a replacement (using spare parts originally built for the other orbiters) and delivered in May 1991. Columbia was lost, with all seven crew, in a re-entry mishap on February 1, 2003.

While all of this was going on, others were suggesting a completely different approach to the future. They stated that NASA was better off using the existing Saturn to launch their space station, supplied and manned using modified Gemini capsules on top of the Air Force's newer Titan II-M. The cost of development for this looked to be considerably less than the shuttle alone, and would have a large space station in orbit earlier. NASA's Space Shuttle program is an ongoing endeavor, started in the late 1960s, that has created the world's first partially reusable space launch system, and the first spacecraft capable of carrying large satellites both to and from low Earth orbit. Each shuttle is designed for a projected lifespan of 100 launches. The original purpose of the program was to ferry supplies to a space station. In reality, the Shuttle is the United States' sole manned launch vehicle and has totally dominated NASA's operations since the mid 1970s. With the construction of the International Space Station the Shuttle has finally begun to be used for its original purpose. In January 2004, it was announced that the Shuttle fleet would be replaced by 2010.

The last remaining debate was over the nature of the boosters. NASA had been looking at no less than four solutions to this problem, one a development of the existing Saturn lower stage, another using "dumb" pressure-fed liquid fuel engines of a new design, and finally either a large single solid rocket, or two (or more) smaller ones. The decision was eventually made on the smaller solids due to their lower development costs (a decision that had been echoed throughout the whole Shuttle program). While the liquid fueled systems provided better performace and enhanced safety, delivery capability to orbit is much more a function of the upper-stage performance and weight than the lower. The money was simply better spent elsewhere.
