What happens if you shoot the rocket down on ascension?
If you are plauing an online multiplayer game, then you are not able to shoot down the rocket. In the game, you have to shoot down the rocket with another rocket launcher and it is part of the missions. you cannot continue without doing so.
A rocket fired into spaceas it moves the total momentum of the rocket and its exhust gases remains the same?

What are the basic parts of a model rocket?
The nose cone, parachute, tube/body, fins, solid fuel engine, launch pad, engine ignition strip, and battery powered electronic ignition switch. A new kit is about thirty dollars maybe a little less. The rocket is reusable as is the launch pad. The normal engines are not reusable, but can be purchased at most hobby stores and at Walmart in packs of five. The engines come in different sized and the rockets come in different levels of complexity. Remember that these hold potential for very serious injury. They can be very fun though with responsible and considerate people.
What are all the search engines called?
I posted the list of search engines from wikipedia in the related links box below.
Is a rocket launcher a gun?
A gun is characterized as a firearm launching any sort of metallic bullet, pellets, or anti-armor explosives. a rocket launcher is a gun. most famous rocket launchers are panzershrek, bazooka, stinger, grenade gun, javelin,e.t.c.
What is the most advanced rocket engine?
A cryogenic rocket engine
What are the disadvantages of cryogenic engines?
It does not live happily to the people
What are two main types of rocket engines?
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
What has the author R W Michel written?
R. W. Michel has written: 'Combustion performance and heat transfer characterization of LOX/hydrocarbon type propellants' -- subject(s): Space shuttles, Liquid oxygen, Oxygen-hydrocarbon rocket engines, Cryogenic rocket propellants
What is a cryogenic engine?
AnswerCryogenic Engines are rocket motors designed for liquid fuels that have to be held at very low "cryogenic" temperatures to be liquid - they would otherwise be gas at normal temperatures. Typically Hydrogen and Oxygen are used which need to be held below 20°K (-423°F) and 90°K (-297°F) to remain liquid. The engine components are also cooled so the fuel doesn't boil to a gas in the lines that feed the engine. The thrust comes from the rapid expansion from liquid to gas with the gas emerging from the motor at very high speed. The energy needed to heat the fuels comes from burning them, once they are gasses. Cryogenic engines are the highest performing rocket motors. One disadvantage is that the fuel tanks tend to be bulky and require heavy insulation to store the propellant. Their high fuel efficiency, however, outweighs this disadvantage.The Space Shuttle's main engines used for liftoff are cryogenic engines. The Shuttle's smaller thrusters for orbital manuvering use non-cyogenic hypergolic fuels, which are compact and are stored at warm temperatures. Currently, only the United States, Russia, China, France, Japan and India have mastered cryogenic rocket technology.
Why only rocket engines can be propelled to space?
Rocket engines are not air breathing engines and hence they can be propelled into space.
What are model rocket engines and what do they do?
Model rocket engines are reproductions of rocket engines that are scaled down to a much smaller size than the real thing. They usually don't do anything and are for display purposes.
What is a example of a rocket fires engines and lifts off?
the rocket is accelerating
Action-reaction engines that propel an object forward?
a rocket
How many engines does a rocket have?
4
Which substance is a liquid fuel used in rocket engine?
Traditionally, rockets use cryogenic (super-cold) oxygen and hydrogen.
Why do fuel tanks of a rocket need to be kept cold before launch?
Many rockets (Including the Space Shuttle) have cryogenic rocket engines. These are rocket engines that very cold liquid propellants. The most common cryogenic engines use Liquid Oxygen (LOX) as an oxidizer and Liquid Hydrogen (LH2) as fuel. Rockets require the fuel and oxidizer to feed into the engines at a very high mass flow rate in order to generate the necessary thrust. The solution is to store oxygen and hydrogen in liquid form, where they are more dense (meaning that they will be fed into the engine at a higher mass flow rate). Because oxygen and hydrogen are gaseous at room temperature, they must be cooled to very low temperatures in order to take on a liquid state. Oxygen must be cooled to -183 degrees C (-297 degrees F) and Hydrogen must be cooled to -253 degrees C (-423 degrees F).
