• Building Up the Unmanned Rocket Fleet Building up the unmanned rocket fleet
  ). Its central component is the cryogenic or core stage. It consists mainly of an aluminum alloy tank containing two compartments for extremely cold liquid hydrogen (LH) and liquid oxygen (LOX), which serve as fuel. The two compartments hold 157 tons: 132 tons of LOX and 25 of LH. The core...
• Ultraviolet-Visible Spectrometry Characterization of
  emission spectrum. and the broadband visible emission spectrum of hybrid rocket motors under a variety of oxidizer to fuel. ratios. Time and spatial profiles were measured along with regression rates. Correlations were drawn. between broadband emission spectra and regression rates. The distribution...
• The X Prize is up for grabs ... 100 kilometers up!
  essentially vertical flight plan. Using the same engines for launch and reentry saves money and reduces complexity, as does using only off-the-shelf components to build the rocket ship. The entire craft is reusable, the only consumables being fuel and oxygen for the crew. The rocket carries a full avionics...
• Rethinking engines
  Rocket engines and the internal-combustion cycle get a remake, thanks to engineering ingenuity. A four- cylinder split-cycle Scuderi engine should be as powerful as a traditional six-cylinder engine. It should also be able to burn almost any combustible fuel. A model of the IPD shows the intricate...
• Paradise Lost
  turbo-fan engine;. rough environment. When we shoot what's called a Standard Mis-. CSD/ARC solid-fuel booster. sile Block IV (SM-2ER Block IV), made by Raytheon, there are four. Range: 870nm (1,609 km). nozzles on this rocket booster and it just roars. You can actually. Speed: Subsonic, about 550mph...
• Wired 9.01: Zip Drive
  NASA scientists are building a hot little ride: Vasimr, a rocket that runs on million-degree plasma and could someday fuel a fast-track trip to Mars. An elite group of NASA scientists, led by an astronaut-physicist with six space shuttle flights under his belt, has set the date when humans...
• So you want to be an astronaut
  seconds away. T-00M6.6S: Main-engine startup. All three main engines power up, the vibrations increase, and you hear the rumble. T-00M00S: Liftoff! Solid rocket boosters add their thrust, pinning you down in your seat with a hard jerk. Everything pops and booms around you. The simulators couldn't do...
• China Adds Precision Strike To Capabilities
  in space. In late 2006 reports emerged of China's use of high-power ground-based lasers to "dazzle" U.S. surveillance satellites. On Feb. 11, 2007, China launched the first successful intercept by its SC-19 direct-ascent antisatellite (ASAT) system, derived from its KT-1 solid-fuel space-launch vehicle...
• Ampac's New Agenda
  of individuals has developed expertise in continuous processing since the 1980s,” says Robinson. “Space shuttle rocket fuel production was the original basis for this effort, at a facility that made 1000 lbs. of materials per hour on pilot-scale unit.” Materials are produced with a continuous...
• Process Creates Ceramics That Won't Shrink Or Change Shape
  , such as those in cellular phones. Other ceramics that have been produced by this process conduct hydrogen ions in fuel cells or act as permanent magnets for speakers, motors, and portable electronic appliances. One calcium-based ceramic that Sandhage and his students have produced is the major component...
