	Model Rockets - Model Rocket Parts
		The heavier the rocket motor the farther the center of gravity is to the rear.
		The model rockets nose cone is shaped to reduce air drag at the front of the rocket and to seal the front of the body tube and the recovery system inside the rocket body tube.
		The larger the fins the farther the center of pressure is to the rear of the model rocket.

	Rocket Simulations
		Rocket Area (A): equal to pi (3.14159) times the radius squared, where radius is half the diameter of the rocket (at its widest point).
		Running a simulation of your rocket flight is a great idea, especially if you aren't that familiar with the physics of a rocket flight and you want to learn more about it.
		Rocket Mass, empty (Mr): since I normally have the rocket's empty weight in ounces, I set this cell equal to weight*0.0284 to get the mass in kilograms.

	About Model Rockets
		I will launch my rocket from a launch rod, tower, or rail that is pointed to within 30 degrees of the vertical to ensure that the rocket flies nearly straight up, and I will use a blast deflector to prevent the motor's exhaust from hitting the ground.
		I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 15 feet away when I launch rockets with D motors or smaller, and 30 feet when I launch larger rockets.
		As a general rule of thumb, your launch field should be at least as wide as 1/4th of the expected altitude of the rocket.

	Russian Rockets
		This rocket is the primary launcher used for manned Russian space flights.
		Zenit, introduced in 1985, is a liquid-fueled launch vehicle that was the first completely new Soviet rocket in 20 years.

	BOTTLE ROCKETS
		The rocket and pad should be observed by the adult and the launching student for the first sign of any problems.
		The launch platform size is not specified, and when it is built large enough and passive restraints are used, it becomes stable enough to have no need of being staked down to the ground.
		Although the size of the launch area can be as small as a front yard for no wind and bare bottle experiments, once good flight characteristics are achieved, the launch area will need to be clear for the size of a football field size.

		Rocketeer Elon Musk and the SpaceX Falcon launcher.
		Once it's in a state of alert, the rocket could launch within minutes to replace a disabled satellite, send one to monitor a particular area, or even deliver bombs.
		The small rockets the Air Force is considering in its Operationally Responsive Spacelift initiative would lift cargo of about a thousand pounds.

	Rocket launch site - Wikipedia, the free encyclopedia
		A rocket launch site is a facility for the launch of rockets.
		A rocket launch site is built as far as possible away from major population centers in order to mitigate risk to bystanders should a rocket experience a catastrophic failure.

	Water rockets. - Launcher Launch Tube
		With a launch tube, the rocket has a chance to accelerate with very little loss of pressure or liquid - this acceleration using the full bore of the nozzle with the thrust being around half of that from the discharging of water during the next phase of thrust.
		Turn the rocket with the launcher attached the right way up and then push the launcher's base tube onto the T piece at the centre of the H-Base, hooking the release string through the dog-lawn skewer.
		This means that if you are going to launch using just air, you will see a massive increase in performance and using only a little bit of water (20 mls or so) will act as a lubricant / sealant on the tube resulting in further gains.

	Rockets for Schools
		Each launch team will be assigned a launch window during which their rocket will under go a safety check, be prepped for flight and then launched.

	Delta
		The missions were simply continued with a new launch vehicle, the Thor-Agena B, which was an improved version of the Thor-Agena A. The booster for the vehicle was a Model DM-21 Thor, basically a Model DM-18C with a higher thrust engine, nose fairing removed, and guidance section replaced by a shorter, lighter transition section.
		By cutting off and restarting as much as 20 minutes after the launch sequence had ended, the Ablestar was able to "correct" its orbit, making it more circular or elliptical as the case might require.
		The Delta launch vehicle family began in 1959 when NASA's Goddard Space Flight Center awarded a contract to Douglas Aircraft Company (now McDonnell Douglas Corporation) to produce and integrate 12 space-launch vehicles.

	Delta II Launch Vehicle
		It provides guidance and control for the rocket resulting in the precise payload deployment that is associated with Delta II launch services.
		Two-stage Delta II rockets typically fly LEO missions, while three-stage Delta II vehicles generally deliver payloads to GTO or are used for deep-space explorations such as NASA's missions to Mars, a comet or near-Earth asteroids.
		Delta II comprises a group of expendable rockets that can be configured as two- or three-stage vehicles and with three, four or nine strap-on graphite epoxy motors (GEMs) depending on mission needs.

	New Scientist Breaking News - Russian rockets to launch from South American base
		The Ariane 4 rocket - retired in 2003 after nearly 160 launches in 15 years - was able to carry between 2 and 5 tonnes to geostationary transfer orbit.
		The company’s Vega rockets launch small scientific satellites weighing no more than 1.5 tonnes into relatively low orbit, while the company's two types of Ariane 5 rockets can launch 6.6 tonnes or 10.0 tonnes into geostationary transfer orbit, respectively.
		The Soyuz rockets normally lift 1.6-tonne-payloads into orbit from Baikonur, but they will get an added boost from Kourou's location nearer to the equator, where the benefit of Earth’s spin is most felt.
