When mix with oxygen, the other fuel component of the main engines, the burning hydrogen produces a large amount of thrust to push the rocket.
Later inflight and just prior to engine shutdown, the oxygen is shut-off prior to oxygen. This sequence allows the rocket engine to shut down safely, as in the absence of oxygen, hydrogen is difficult to ignite by the hot metal surface of the exhaust fins.
The space shuttle flies into space. It can travel to different planets.
by using science which is by NASA
Using a space shuttle.
The Space Shuttle was the first US spacecraft built to accommodate more than 3 astronauts. After the retirement of the Space Shuttle, most cargo is carried to the ISS by unmanned rockets.
In space, they don't. If they are in a space shuttle, however, they would move themselves using handlebars attached to the shuttle designed specifically for propelling themselves.
The space shuttle was both a marvel and huge.
since 1981
Problem? None, it is an awesome fuel. There are dangers, but no fuel as safe for the power. Any fuel can explode. This is easier to deal with and control then most others.
The space shuttle is able to go to the moon by using a special type of fuel and rises up the earth atmosphere until it overcomes the force of gravity.
If you would be melting ice, and you collected all the water dripping off the melting icecube and put it into an icecube maker, and stuck it in the freezer, you would be reversing the chemical change. I think?
They never used Explorer. It was built as a replica to allow people to see inside a Space Shuttle at the Kennedy Space Center Visitor Complex in Florida. It has since been moved to Houston.
In a space shuttle usually but now that has been decommisioned the only way to get into space is to build your own (safe) space craft or go to Russia where you can get into space using their space craft.
