How Spacecraft know where and which planet it is made to go? Why there is a specific date and time for launching a Space craft

Spacecraft, A well-known medium to make a communication with the universe but do you know how the Spacecraft know where it is designed to go. Why there is always a fixed time for its journey in the space. Why its body made up of aluminum.

What is spacecraft or spaceship?

spacecraft is a vehicle or machine designed to fly in outer space. Spacecraft Is designed to fly with or without any human. Airplanes are not able to fly in outer space because of no oxygen in the space. Spacecraft is made to do a certain task in the space which includes communications, earth observation and many more. These spacecraft is the only medium for astronauts to survive in the space and to know about the universe.

Why spacecraft body made with aluminum, not with steel?

Because the spaceships are made to fly for long in the space. Every vehicle needs to be solid from its outer. Spaceships need to be solid for safety, but they also need to be light. Because they are made to go where earth gravitational force is zero and earth can not pull spacecraft with its force. It must do its journey with less fuel and propellant. If the mass of Spacecraft is greater, due to gravitational force equation it takes more force to repel itself from the earth which takes more fuel and expensive.

This is why Aluminum and aluminum composite materials are used on spacecraft. Using titanium alloys can also strengthen the body of the ship. The space shuttle also had very special thermal protection tiles, which helped it survive the heat of re-entry. They are made a ceramic composite, with the bottom of the tiles made from a carbon composite to provide for the most heat protection.

How does spaceship know where it’s destination?

We know that all the objects in the space are moving around the sun. So how a spaceship knows among lots of moving objects in front of it where it goes. This is done by the Scientist before its launching. Scientist waits for the perfect time according to the clock of the solar system. They must know the clockwork of the solar system. They work on the gravity also because the objects in the solar system are moving. The Gravity exerted by the large planets rotating in the solar system can bend the flight of Space craft. The Scientist use this Gravity to make the spacecraft to  pull in orbits

So Space Craft is launched at a perfect time and at a perfect date. All work is done by the Scientist before launching of the satellite, Once a spacecraft is in flight, small course corrections can be performed.
