Q&A: what obstacles do rockets have to overcome to get in to space?

Question by Arman: what obstacles do rockets have to overcome to get in to space?
gravity is an example i need more info for my science assignment links would help too

Best answer:

Answer by always
You are right – gravity is the biggest factor.

Apart from gravitation forces, there are frictional forces acting because of the air/impurities in the atmosphere.

We shot a rocket, and we lost it.

    the propulsion pushes the rocket (not pulls) so if it isn’t perfectly symmetrical then it will spin out of control.

    The chemical reaction also has to be a steady release and can’t explode

    Rockets have to overcome many obstacles to get into space. Gravity, as you already stated, is just one. The others include:

    The moon’s gravitational pull.
    Dense cloud coverage in the Earth’s moleculosphere.
    Formulaic dissipation of nomenclature.

  3. Petrusclavus says:

    Drag – air friction. The rocket must also achieve orbital velocity. Not enough speed and it falls back to earth.
    Load loss – fuel for the burn must be carried, it uses many kilo’s of fuel to get the last kilo of fuel into place in low orbit to use- burn fuel to carry fuel.

  4. Starrysky says:

    “The moon’s gravitational pull.” has nothing to do with leaving the Earth and going into space. It is too small and too far away to make any difference until you get within 8000 miles of the moon.
    “Dense cloud coverage in the Earth’s moleculosphere.” “moleculosphere” is not a word. NASA has launched a Saturn V moonrocket through a thunderstorm and got a lightning strike.
    “Formulaic dissipation of nomenclature” is a nonsense assembly of words.
    Beware of people like Sarah B who try to trick you into thinking they know something.

    People’s telecommanding.

    Earths gravity: to get high enough/far enough away from the Earth’s mass and gravity well to not fall back in/down when the rocket runs out of fuel.

    Atmosphere: as it launches, the rocket will experience turbulence and heat due to atmospheric buffeting, and friction as it approaches the speed of sound (and beyond- to enter orbit the escape velocity is mach27). At these speeds the heat will be considerable, but will lessen as the rocket gets higher and into thinner atmosphere. Small hobby rockets get this stability from the fins- which work only because the hobby rocket never leaves the thicker atmosphere; where the fins work best.

    Stability. A rocket is alot like balancing a broomstick in the palm of your hand, and pushing it upwards- the rocket thruster is at the bottom, but all the weight is above it. Therefore it needs active control of the thrust; shifting it around to keep the motor “under” the rocket at all times. … A flip is a bad thing

    Some rocket science: there needs to be a plan, a navigation course plotted, speed and orbital calculations figured out ahead of time, how those calculations affect the rocket’s size, weight, and fuel requirements, how THAT affects the total weight of the rocket, and from that how much thrust and fuel requirements the launch booster stage of the rocket needs to be to get it all off the ground, and going in the correct direction.
