Astronaut Visits Students in Los Angeles NASA astronaut and former National Football League player, Leland Melvin, brought the thrill of space exploration to students at Elliott Middle School in Pasadena, Calif. Melvin encouraged students to study science and mathematics, and invited them to nominate their teachers for the Educator Astronaut program. The program, which will send teachers into space as fully trained astronauts, requires applications by April 30, 2003. More Educator Astronaut program information NASA Study Finds Solar Trend That Can Change Climate A NASA-funded study finds the amount of solar radiation the Sun emits during times of quiet sunspot activity has increased by nearly .05 percent per decade since the late 1970sa trend that, if sustained, could contribute to climate change. Data from three JPL instruments contributed to the study, which may help climatologists distinguish between solar and man-made influences on climate.

Laser Launch Systems The Lawrence Livermore National Laboratory's Special Studies Program (within The Advanced Technology Program (ATP) of O Division) has examined alternative spacecraft propulsion concepts to meet performance or mission objectives. Laser propulsion concepts have been described for several decades. The laser beam is used to heat a propellant with the energetic expansion driving the craft. A series of ATP devised tests were conducted in which a laser beam was directed at a pusher plate with machined paraboloid dimples. Light was focused by each dimple on a spot behind the plate. The focused beam heated air pockets and the expanding pockets imparted a thrust to the plate. This *concept* provides respectable thrust in the atmosphere. In *space* (vacuum) the dimpled plate is jettisoned to expose a block of solid propellant which is ablated by the laser beam to produce thrust.

Beginner's Guide to Propulsion Glenn Research Center Welcome to the Beginner's Guide to Propulsion What is propulsion? The word is derived from two Latin words: pro meaning before or forwards and pellere meaning to drive. Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction. A gas, or working fluid , is accelerated by the engine, and the reaction to this acceleration produces a force on the engine. A general derivation of the thrust equation shows that the amount of thrust generated depends on the mass flow through the engine and the exit velocity of the gas. Different propulsion systems generate thrust in slightly different ways. We will discuss four principal propulsion systems: the propeller,

Experimental Rocket Propulsion Society The Bay Area's Non-profit Liquid Fuel Rocket Engine Design and Test Team HOME Intro FAQ Mailing list ... Stats Search ERPS: The E.R.P.S. was founded in February of 1993 to gather together interested amateurs to learn about, design, build, and test liquid fuel rocket engines. The group early on decided to concentrate on developing and testing high density storable propellant combinations because they allowed the maximum amount of work to be done with the minimum amount of risk to life and limb. After research and consultations, high density Hydrogen Peroxide (H O ) was selected as the oxidizer of choice, with the intent to combine it with a high-density kerosene such as JP5 or regular Jet-A. Peroxide, when catalyzed, produces steam (2 H O) and pure oxygen (O ) at high temperatures. Peroxide makes a fair mono-propellant when used in concentrations above 95% and there was historical experience (the British 'Black Knight' program of the late 60's and early 70's) to show that respectable performances and capabilities could be developed even at lower concentration when combined with a high density liquid hydrocarbon. The British, however, limited themselves by the catalyst they chose to work with, silver screens. Because the melting point of silver is low (936.93 o C), using peroxide at concentrations above about 85% generates a heat of reaction high enough to melt the silver and thereby reduce and eventually eliminate the "catalyst" from the reaction. The physical properties of the reaction and the type of catalyst used, therefore, limited their performance.

Space Science News home ION PROPULSION Over 50 Years in the Making April 6, 1999: The ion propulsion system on Deep Space 1 is the culmination of over 50 years of development on electric engine systems in space. Launched on Oct. 24, 1998, Deep Space 1 will be the first spacecraft to actually use ion propulsion to reach another planetary body. The engineering that makes this possible represents a journey that started more than half a century ago, when modern rocketry was invented. Looking back, Ernst Stuhlinger, a world expert on electric propulsion, said that the technology "owed its life-giving spark to Wernher von Braun." Recent Headlines December 3: Mars Polar Lander nears touchdown December 2: What next, Leonids? November 30: Polar Lander Mission Overview November 30: Learning how to make a clean sweep in space Dr. Wernher von Braun, a rocket scientist from Germany, was first introduced to the possibility of electric propulsion in the 1930s, through his mentor, Dr. Hermann Oberth. But von Braun started his career working on chemical propulsion systems. Right: An artist's concept depicts the Deep Space 1 probe with its ion engine operating at full thrust. (Links to
