Why are sparks seen just below Space shuttle main engines prior to main engine ignition?

The spray of sparks below the Shuttle's main engine is purely there to ensure any excess hydrogen that has escaped through the nozzles is burnt away. The engines are ignited by "Spark Ignitors" like a spark plug in the engine.

Can you burn fossil fuels on the moon?
to burn any material, not only fossil fuel, we need three things: 1. Fuel (any material that can be burned, ex: fossil fuel, wood, paper, etc) 2. Ignition (high temperature, or fire sparks) 3. Air and now, if you want to burn fossil fuel on the moon you also need these three factors.. the answer is : NO, because there is no air on the moon ( if there is, it's just in a very small volume and can't be used to burn fossil fuel) ~ ANSWER 2.0 BY RUSSIANS 1)there is no fossil fuel on the moon 2)there no oxygen on the moon however if you bring your own, like the FUEL AND OXIDIZER for rocket engines of American space craft fossil fuel will burn just fine. i believe the fuel used was hydrogen witch is non petroleum so technically it was not fossil fuel. but never the less it was fire in vacuum.
What did the miller-urey experiment do?
The Urey Miller experiment took a mixture of materials thought to be present on earth and energized it by passing and electrical discharge through the material. The important organic molecules that were produced were amino acids and other complex molecules.
What are some folktales about stars?
There is the Saora folktale about the eldest son who attended a wedding. At the wedding, his sister-in-law tricked him and filled his pipe with salt. When the eldest son lit the pipe, it started to spark. He was not afraid and blew really hard into the pipe, sending the sparks into the sky. Kind of lame, I know. The Greeks believed that when you died, if you were famous, then you were turned into a constellation. Maori myths believe the constellations are the descendants of Rangi(the sky) and Papa(the Earth). The Milky Way was thought as Te Ikaroa, the great fish of Rangi. The African Bantu tribe believed the great god Bumba threw up the sun which dried some of the ocean which left land. Then he threw up the moon and stars, then animals, and finally humans. Another African myth tells of a girl who became so angry when her mother refused to give her any more delicious roasted root that she grabbed the roots that were roasting on a nearby fire and threw their ashes into the sky. The red and white ashes became the red and white stars that make up the Milky Way.
What is the most common gases inside the sun?
I'm no astrophysicist (not even a scientist), but I'm assuming the most common gas inside the sun is going to be Hydrogen. Hydrogen is the most common element in the Universe and gives off a massive amount of energy when fused through nuclear fusion. Most stars are formed by giant clouds of dense hydrogen gas (and dust) that are slowly compacted together by gravity over thousands of years. The more compacted it gets, the higher the temps go, and ultimately at around 15million degrees, nuclear fusion sparks and a star is born. At the moment of birth, the star blasts a nuclear shockwave out that not only signals its birth, but also serves to blast the remaining matter it did not use in its creation to help form a local system of planets, moons, and asteroids. Over time, however, the star will burn through its hydrogen and create heavier and heavier elements like helium, oxygen, and carbon. By the time a star like ours begins to fuse carbon, it begins its death cycle, as the next element it tries to make is iron, which gives off no energy when fused and that is when a star either swells into a red giant (like our sun will) or goes supernova (in the case of the really big stars). So our sun should still contain mostly hydrogen, but in its core it is slowly creating an onion-like structure of heavier and heavier elements as it burns through its fuel.
What does ignition protection system do?
It keeps sparks out when ignition of the engine
Car will turnover but not start how do you fix?
Answer checkn see if u have spark,getting gasfirst test the battery if it is low then charge it check witch lights come up when u turn the ignition on and check rad water and engine oil It's not a good Idea to check for sparks on a car with computerized engines.
Ignition sparks not bright is that ok?
Depends on the ambient light you are working in.
In a computer-controlled ignition system the ignition module does what?
The ignition control module acts like the coil and sends the sparks to the correct cylinder when the computer tells it to.
Ignition only sparks when you turn the key off1995 Chevy S-10 Blazer. Rplaces ModuleCap rotor wires.It turns over with no sparkWhen the key gets turned off that instant is when it sparks.?
Defective ignition switch?
Where is the distributor cap on s 2001 Mitsubishi Galant?
There are none. The car is a four cylinder and has 2 ignition coils on the top of the engine. One coil sparks two cylinders. Follow your plug wires on the top of the engine. Igition caoils go for about $125.00 each.
Whats the difference between engines running on diesel and gasoline?
Gas engines use spark plugs to ignite the air fuel mixture and diesel engines use high cylinder compression to ignite the fuel air mixture. Other than that they are similar. <><><> Diesel engines ignite the fuel by using high compression: as the engine compresses the air inside the combustion chamber, it reaches around 1000 degrees, at which point diesel fuel is injected into the combustion chamber, and it ignites. Gasoline engines use the sparks from spark plugs to ignite the gasoline/air mixture in the engines' combustion chambers after it has been compressed. Because separate sparks are used the amount of compression required in a gasoline engine is a lot less than would be necessary in a diesel engine. The main reason diesel engines are heavier and more expensive to make than gasoline engines is because, to be able to withstand the much higher compression, diesel engines have to be made much stronger by having thicker cylinder walls, compression chambers, pistons, connecting rods, crankshafts, etc.
What is the difference between spark plugs and glow plugs?
A spark plug actually sparks, and is generally only used in a gasoline engine. A glow plug just gets warm (glows), and is used in some diesel engines.The difference between spark plugs and glow plugs is that a spark plug delivers current from an ignition system to the combustion chamber while a glow plug is a heating device that aids starting diesel engines.A spark plug actually sparks, and is generally only used in a gasoline engine.

Why is the thrust of engines important?
The friction of rubbing up and down causes the sparks to ignite and to spill everywhere.
What does it mean when sparks come from your distributor?
It means it is time for a new distributor cap, rotor and ignition wires.
How many sparks plugs are there for a 2003 Ford Expedition?
8 for the 4.6 L and 5.4 L V8 engines
What if your 91 capri won't startno sparks on plugsAm getting fuel and ignition coil is new?
Have the ignition module in distributor checked.... could solve your problem (it solved mine!!)
