Space Shuttle program
Space Shuttle program Space Shuttle Columbia, 1981 (NASA) 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

Hubble Space Telescope
Hubble Space Telescope The Hubble Space Telescope (HST, or Hubble) is a telescope located at the outer edges of Earth's atmosphere, about 600 kilometerss above the ground, orbiting the Earth every 100 minutes. It was placed into orbit, in April 1990, as a joint project of NASA and the ESA. The telescope can achieve optical resolutions greater than 0.1 arcseconds. The HST is named after Edwin Hubble. It is scheduled for replacement, by the James Webb Space Telescope (JWST), in 2009. Every day, the Hubble Space Telescope archives 3 to 5 gigabytes of data and delivers between 10 and 15 gigabytes to astronomers. Working outside the atmosphere has advantages because the atmosphere obscures images and filters out electromagnetic radiation at certain wavelengths, mainly in the infrared. Hubble

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.

Meanwhile the Air Force had a continuing interest in smaller systems with more rapid turn-around times, and were involved in their own spaceplane project called Dynasoar. In several instances groups from both worked together to investigate the state of the art.

John Glenn
and politician. John Glenn during the Mercury program 1962 (NASA) Born in Cambridge, Ohio, he obtained a BS in Engineering from Muskingum College. He enrolled in the Naval Aviation Cadet Program in 1942, and was assigned to the Marines VMO-155 group in 1944. Glenn flew a Corsair over the Marshall Islands, specifically Maloelap, where he was tasked with attacking anti-aircraft gunnery and ground bombardment. By 1945, he was transferred to the Patuxent River Test Pilot School, where he became a test pilot and was promoted to Captain by the war's end. After the war, Glenn flew patrol missions in North China, based in Guam, but in 1948 he became an flight instructor at Corpus Christi, Texas, then undertook an amphibious warfare course and was assigned a staff assignment, all the while

Jean Michel Jarre
displays and fireworks. One of his albums, Musique pour supermarchés had a print run on only a single copy, which was auctioned to raise money for French artists. In 1986 he worked with NASA; astronaut Ronald McNair was to play the saxophone part of Jarre's piece Rendez-Vous VI while in orbit on board the Space Shuttle Challenger. It was to have been the first piece of music recorded in space, for the album Rendez-Vous. After the Challenger disaster of January 28, 1986, the piece was recorded with a different saxophonist, retitled Ron's piece and the album dedicated to the seven Challenger astronauts. He was married to actress and photographer Charlotte Rampling. He is a UNESCO Goodwill Ambassador.

NASA had conducted a series of paper-projects throughout the 1960s on the topic of reusable spacecraft to replace their expedient "one-off" systems like Mercury, Gemini, and Apollo.

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.

Instead they looked to reduce the year-to-year costs of development to a stable figure. That is, they wished to see the development budgets spread out over several more years. This is somewhat difficult to do--you can't build half a rocket. The result was another intense series of redesigns in which the re-usable booster was eventually abandoned as impossible to pay for. Instead a series of simpler rockets would launch the system, and then drop away for recovery. Another change was that the fuel for the shuttle itself was placed in an external tank instead of internal tanks from the previous designs. This allowed a larger payload bay in an otherwise much smaller craft, although it also meant throwing away the tankage after each launch.
