Why did Apollo 8 blow up?
Apollo 8 did not blow up. Apollo 8 was the first manned spacecraft to orbit the moon. It returned to the Earth safely. Apollo 13 is the spacecraft that had an explosion while traveling to the moon.
How is a spacecraft launched?
There are about four forces that act on a lifting off spacecraft . The four forces are the thrust force, the weight of the spacecraft, the drag and the lift force.

How does the slingshot effect or gravity work to assist a change in orbit of a spacecraft?
Gravity AssistIt's called Gravity Assist. Overcoming gravity is all about velocity. Escaping Earth's gravity requires approximately 25,000 mph. Escaping the Solar System needs more than 45,000mph. We dont have a large enough rocket to achieve that speed so spacecraft can use a planets gravity to increase its velocity and then the planet can "slingshot" it onto a new trjectory toward the next target. The gravity of a large object can "pull" something to a higher velocity and then, rather than crash into the object, the craft can just miss the planet or moon and, for a moment, go into orbit. The centripital force of the orbit will increase the craft's velocity and "shoot" it off on a new trajectory. ------------Nope, that's wrong. An orbit is (by definition) symmetrical. There is no change of energy in an orbit (that is, no change to the sum of kinetic energy and potential energy). Any kinetic energy gained by a spacecraft on approach to a planet, by trading gravitational potential, must be lost on leaving it, as the kinetic energy is converted back into potential.You can only make sense of a gravity assist by also considering the planet's orbit around the sun. By arranging a suitable slingshot configuration you can steal the orbital energy of the planet around the sun and give it to the spacecraft. The planet ends up in a lower (less energetic) orbit, while the spacecraft ends up in a higher orbit relative to the sun. It has nothing to do with the centripetal force of the spacecraft's orbit or hyperbolic trajectory around the *planet*.
How do satellites get into space?
They are placed on top of a rocket, which accelerates them until they "escape" the atmosphere and enter space. Satellites are spacecraft that orbit the Earth or a planet, while those that travel through space are usually called "space probes."

How does a space shuttle get to space?
The first stage would be launch of course, which uses the main engines (three liquid fueled rockets) and the two Solid Rocket Boosters that are ignited right after the main engines start. After 2 minutes the Boosters are done and are released, while the main engines continue until the shuttle is going fast enough for orbit. The total time from launch to orbit is 9 minutes.
Does Saturn revolve while in orbit?
No Saturn does not revolve while in a orbit

What is the difference between an aircraft and a spacecraft?
Aircraft fly through air and spacecraft fly in space.
What is the difference between a flyby spacecraft and an orbiter?
The main difference between a flyby spacecraft and an orbiter is the guidance computer programming: which causes a flyby to go by the planet and take pictures and other readings allowed in the limited time of the single pass, while an orbiter is captured into an orbit about the planet where it has a much longer period to take pictures and other readings.
How long will the International Space Station be in space?
It is planned to stay in orbit in its current form until at least 2020. In principle it can stay in orbit as long as nothing breaks and there is money for flying people, supplies and fuel to it. Fuel is important because there is still a little bit of air up there that causes it to drop back to earth very slowly, so every once in a while it either needs to fire its rocket engines or be "pushed" by a docked spacecraft like Progress or the Shuttle. You also need people to look after it and fix parts that wear out or break.
Is spacecraft able to land in Venus'?
spacecraft can land on Venus but they melt, it's 400oC,, probes have been sent there but they were destroyed by the heat after a while
Why spacecraft get hot while enter into the earths atmosphere?
A spacecraft has to work against the air friction when it enters our atmosphere. Thus it gets heated a
