Practical Rocketry: by National Aeronautics and Space Administration

Excerpt: Rocket Engines and Their Propellants. Most rockets today operate with either solid or liquid propellants. The word propellant does not mean simply fuel, as you might think; it means both fuel and oxidizer. The fuel is the chemical the rocket burns but, for burning to take place, an oxidizer (oxygen) must be present. Jet engines draw oxygen into their engines from the surrounding air. Rockets do not have the luxury that jet planes have; they must carry oxygen wit...

Tracker 3 Object Tracking and Image Processing Software: by Robert...

Introduction: Tracker is an object tracking and image processing program designed to help with the analysis of images generated by combustion and fluid physics experiments. Experiments are often recorded on film or video tape for later analysis. Tracker automates the process of examining each frame of the recorded experiment, performing image processing operations to bring out the desired detail, and recording the positions of the objects of interest. Tracker can load se...

Investigating the Structure of Paramagnetic Aggregates from Colloi...

Overview: InSPACE is a microgravity fluid physics experiment that will be performed on the International Space Station (ISS). The purpose of this investigation is to obtain fundamental data of the complex properties of an exciting class of smart materials termed magnetorheological (MR) fluids. MR fluids are suspensions of small (micron-sized) super paramagnetic particles in a nonmagnetic medium. These controllable fluids can quickly transition into a nearly solid like st...

Rocket Principles: by National Aeronautics and Space Administration

Excerpt: When we think of rockets, we rarely think of balloons. Instead, our attention is drawn to the giant vehicles that carry satellites into orbit and spacecraft to the Moon and planets. Nevertheless, there is a strong similarity between the two. The only significant difference is the way the pressurized gas is produced. With space rockets, the gas is produced by burning propellants that can be solid or liquid in form or a combination of the two. One of the interesti...

Brief History of Rockets: by National Aeronautics and Space Admini...

Excerpt: One of the first devices to successfully employ the principles essential to rocket flight was a wooden bird. The writings of Aulus Gellius, a Roman, tell a story of a Greek named Archytas who lived in the city of Tarentum, now a part of southern Italy. Somewhere around the year 400 B.C., Archytas mystified and amused the citizens of Tarentum by flying a pigeon made of wood. Escaping steam propelled the bird suspended on wires. The pigeon used the action-reaction...

The Divine Comedy

By: Alighieri, Dante, 1265-1321

CANTO I: IN the midway of this our mortal life, I found me in a gloomy wood, astray Gone from the path direct: and e'en to tell It were no easy task, how savage wild That forest, how robust and rough its growth, Which to remember only, my dismay Renews, in bitterness not far from death. Yet to discourse of what there good befell, All else will I relate discover'd there. How first I enter'd it I scarce can say, Such sleepy dullness in that instant weigh'd My senses down, ...
