What are the things you need to consider before taking a rocket to launch?

To launch, the rocket needs enough propellants so that the thrust pushing the rocket up is greater than the force of gravity pulling the rocket down. A rocket needs to speed up to at least 17,800 miles per hour—and fly above most of the atmosphere, in a curved path around Earth.

Why do rockets have fins?

Fins control direction and stability The stability of a rocket is its ability to keep flying through the air pointing in the right direction without wobbling or tumbling. Fins are used on smaller rockets to provide this stability and control direction.

What is the best place to launch a rocket?

Rockets can most easily reach satellite orbits if launched near the equator in an easterly direction, as this maximizes use of the Earth’s rotational speed (465 m/s at the equator). Such launches also provide a desirable orientation for arriving at a geostationary orbit.

Why are rockets launched from sea level?

Existing engineering materials allow the constuction of towers to heights of many kilometers. Orbital launch from a high altitude has significant advantages over sea-level launch due to the reduced atmospheric pressure, resulting in lower atmospheric drag on the vehicle and allowing higher rocket engine performance.

What do the nose cones and fins do?

The aerodynamic shape of the nose cone helps prevent air from slowing the rocket. The fins help guide the rocket to fly straight.

Why are most rocket launch sites located near the equator?

It’s easy to notice that most launch sites are located close to the Equator. This is because rockets launched from sites near the Equator get an additional natural boost that helps save the cost of putting in extra fuel and boosters. It’s preferred to establish a launch site in a coastal region

What are the advantages of equequatorial launch sites?

Equatorial launch sites offered certain advantages over facilities within the continental United States. A launching due east from a site on the Equator could take advantage of the earth’s maximum rotational velocity (460 meters per second) to achieve orbital speed.

Where are launchlaunch sites located?

Launch sites all over the world. It’s easy to notice that most launch sites are located close to the Equator. This is because rockets launched from sites near the Equator get an additional natural boost that helps save the cost of putting in extra fuel and boosters.

Why is it better to launch a spaceship from the equator?

Why is it better to launch a spaceship from near the equator? When a spacecraft is launched into orbit, it should end up spinning around the Earth quickly enough not to be pulled back in by the Earth’s gravity. The huge rockets used in launching a spaceship help this to happen by giving a huge amount of thrust, enough to achieve escape velocity.
