Category: About Rockets
Rocket engines are, on the one hand, so simple that you can build and fly your own model rockets very inexpensively (see the links on the last page of the article for details). On the other hand, rocket engines (and their fuel systems) are so complicated that only three countries have actually ever put people in orbit. In this article, we will look at rocket engines to understand how they work, as well as to understand some of the complexity surrounding them.
When most people think about motors or engines, they think about rotation. For example, a reciprocating gasoline engine in a car produces rotational energy to drive the wheels. An electric motor produces rotational energy to drive a fan or spin a disk. A steam engine is used to do the same thing, as is a steam turbine and most gas turbines. Rocket engines are fundamentally different. Rocket engines are reaction engines. The basic principle driving a rocket engine is the famous Newtonian principle that “to every action there is an equal and opposite reaction.” A rocket engine is throwing mass in one direction and benefiting from the reaction that occurs in the other direction as a result.

Laika was a russian female dog. She was the first animal to go into space. On Novemeber 3rd 1957 russia sent her up into orbit, where she later died, we think that she died from overheating. the air craft that Laika went up in was called the Sputnik 2. There were 3 dogs trained for the sputnik 2 flight; Albina, Mushka and Laika. After the 3 of them were trained, Laika got selected and trained further. Mushka was used though as a test instrumentation and life support.
Laika was originally a stray wandering the streets of moscow.
On April 11, 2008, Russia made a monument for Laika. It features as a dog standing on top of a rocket.
A. No, that is not true. NASA has studied the effects of exhaust from the Space Shuttle’s solid rocket motors on the ozone. In a 1990 report to Congress, NASA found that the chlorine released annually in the stratosphere (assuming launches of nine Shuttle missions and six Titan IVs — which also have solid rocket motors — per year) would be about 0.25 percent of the total amount of halocarbons released annually worldwide (0.725 kilotons by the Shuttle 300 kilotons from all sources).
he Space Shuttle Endeavour, the orbiter built to replace the Space Shuttle Challenger, cost approximately $1.7 billion.
an ACTUAL Rocket....A
Before humans went into space, several animals were launched into space, including numerous MONKEYS! They did this so that scientists could investigate the biological effects of space travel on MONKEYS before they sent up humans.
The United States launched flights containing MONKEYS between 1948-1961 with one flight in 1969 and one in 1985. France launched two MONKEY carrying flights in 1967. The Soviet Union and Russia launched MONKEYS into space between 1983 and 1996.
