The group whose description is wonderful, together with imaginative, beautiful and functional design, will be the winner.Reference for TeachingSpace program in the futureThe risk takers and visionaries of this agency have expanded human knowledge, have revolutionized our understanding of the universe, and produced technological advances that have benefited all of humanity.Inspired by all that has come before, and guided by clear objectives, today they set a new course for America’s space program.They will give NASA a new focus and vision for future exploration.They will build new ships to carry man forward into the universe, to gain a new foothold on the moon, and to prepare for new journeys to worlds beyond their own.Their current programs and vehicles for exploring space have brought them far.The Space Shuttle has flown more than a hundred missions.It has been used to conduct important research and to increase the sum of human knowledge.Shuttle crews, and the scientists and engineers whoTelescopes—including those in space—have revealed more than 100 planets in the last decade alone.Probes have shown them stunning images of the rings of Saturn and the outer planets of our solar system.Robotic explorers have found evidence of water—a key ingredient for life—on Mars and on the moons of Jupiter.At this very hour, the Mars Exploration Rover Spirit isIt is time for America to take the next steps.Their first goal is to complete the International Space Station by 2010.They will focus their future research aboard the station on the long-term effects of space travel on human biology.The environment of space is hostile to human beings.Radiation and weightlessness pose dangers to human health, and we have much to learn about their long-term effects before human crews can venture through the vast voids of space for months at a time.Research on board the station and here on Earth will help us better understand and overcome the obstacles that limit exploration.Through these efforts we will develop the skills and techniques necessary to sustain further space exploration.The second goal is to develop and test a new spacecraft, the Crew Exploration V ehicle, by 2008, and to conduct the first manned mission no later than 2014.The Crew Exploration Vehicle will be capable of ferrying astronauts and scientists to the Space Station after the shuttle is retired.But the main purpose of this spacecraft will be to carry astronauts beyond our orbit to other worlds.This will be the first spacecraft of its kind since the Apollo Command Module.The third goal is to return to the moon by 2020, as the launching point for missions beyond. Beginning no later than 2008, they will send a series of robotic missions to the lunar surface to research and prepare for future human ing the Crew Exploration Vehicle, they will undertake extended human missions to the moon as early as 2015, with the goal of living and working there for increasingly extended periods.With the experience and knowledge gained on the moon, man will then be ready to take the next steps of space exploration: human missions to Mars and to worlds beyond.Yet the human thirst for knowledge ultimately cannot be satisfied by even the most vivid pictures, or the mostdetailed measurements. And only human beings are capable of adapting to the inevitable uncertainties posed by space travel.GalaxyAny of the systems of stars and interstellar matter makes up the Cosmos.Many such assemblages are so enormous that they contain hundreds of billions of stars.Nature has provided an immensely varied array of galaxies, ranging from faint, diffuse dwarf objects to brilliant, spiral-shaped giants.Virtually all galaxies appear to have been formed soon after the universe began, and they pervade space, even into the depths of the farthest reaches penetrated by powerful modern telescopes.Galaxies usually exist in clusters, some of which in turn are grouped into larger clusters measuring hundreds of millions of light-years across.(A light-year is the distance traversed by light in one year, traveling at a velocity of 300 000 kilometers per second, or 650 000 000 miles per hour.) These so-called super clusters are separated by nearly empty voids, causing the gross structure of the universe to look somewhat like a network of sheets and chains of galaxies.Galaxies differ from one another in shape, with variations resulting from the way in which the systems were formed.Depending on the initial conditions in the pregalactic gas some 15 000 000 000 years ago, galaxies formed either as slowly turning, smoothly structured, round systems of stars and gas or as rapidly rotating pinwheels of such entities.Other differences between galaxies have been observed and are thought to reflect evolutionary changes.Some galaxies are rife with activity: they are the sites of star formation with its attendant glowing gas and clouds of dust and molecular complexes.Others, by contrast, are quiescent, having long ago ceased to form new stars.Perhaps the most conspicuous evolutionary changes in galaxies occur in their nuclei, where evidence suggests that in many cases super massive objects—probably black holes—formed when the galaxies were young.Such phenomena occurred several billion years ago and are now observed as brilliant objects called quasars.The existence of galaxies was not recognized until the early 20th century.Since then, however, galaxies have become one of the focal points of astronomical investigation.The notable developments and achievements in the study of galaxies are surveyed here.Included in the discussion are the external galaxies (i.e., those lying outside the Milky Way Galaxy, the local galaxy to which the Sun and Earth belong), their distribution in clusters and super clusters, and the evolution of galaxies and quasars.For further details on the Milky Way Galaxy, see Milky WayA future vehicleWhile many technological advances occur in an evolutionary manner, occasionally arevolutionary technological appears on the horizon that creates startling new conditions and profound changes.Such is the case with the privately developed Moller Skycar, which is namedThe LAMV is a vertical take-off and landing aircraft that can fly in a quick, quiet, and agile manner.It is a new type of vehicle that combines the speed of an airplane and the vertical take-off capability of a helicopter with some characteristics of a ground vehicle, but without the limitations of any of those existiThe LAMV is not operated like traditional fixed—or rotary-wing aircraft.It has only two hand-operator uses to direct the redundant computer control twists to select the desired operating altitude and moves fore and aft to select the rate of climb.The right-hand control twists to select the vehicle’s direction and moves side-to-side to provide transverse (crosswise) movement during the hover and early-transition-to-flight phases of operation; it also moves fore and aft to controlThe LAMV of the future will be 18 feet long, 10 feet wide, and 6 feet high and weight 2200 pounds.It will hold four passengers and a payload of 875 pounds (including fuel).The vehicle will have a maximum rate of climb of 6400 feet per minute and an operational ceiling of 30 000 feet.It will attain a top speed of 390 miles per hour at an altitude of 6000 feet and a cruising speed of 350 miles per hour at 25 000 feet, and it will have a maximum range of 900 miles at 80 passenger miles per gallon.The LAMV also will be quiet enough to function as an acoustic“stealth”plane at 500 feet.It will have a vertical take-off and landing capability and emergency airframe parachutes, and it will be capable of usingThe potential economic advantages of the LAMV are worth mentioning.Its fuel-efficient engines and ability to operate on various fuels will low fuel costs.The LAMV uses one-fourth of the fuel per passenger mile used by the tilt-rotor V-22 Osprey or high performance helicopters.TheHowever, once the LAMV technology matures, its military possibilities are startling.We in the Army combat service support“futures”arena are encouraged by the develo pments so far and hope that the LAMV will be ready for Army fielding around 2010.The LAMV can become a reality in our Army and possibility in the other armed services as well.Without any doubt, this technological innovation will succeed internationally inn the private, commercial, and military sectors.I hope that the US Army will be the first army in the world to embrace and exploit this technology.But sooner rather than later, this aerial vehicle technology will affect all of our lives.It is just over the horizon.。
