HOW HUBBLE TELESCOPE ARE LIFTED INTO ORBIT?
Spacecraft like the
Hubble Telescope are fitted into orbit by by the space shuttle. In that case the space shuttle itself is lifted by Rockets into Orbit. The spacecraft to be deployed be deployed is Riding snugly in the cargo Bay. At a certain height, the spacecraft is rejected and small Rockets On It Move It to the proper Orbit altitude. The telescope measures 13.1 m (43.5 ft) in length, 4.27 m (14.0 ft) in diameter, and weighs 11,000 kg (25,500 lb). Note the size of the work of standing near the base of the telescope.

HOW BIG IS A SPACE STATION?
Once completed, the dimensions of the the the International
Space Station (ISS) will be approximately 108.5 meters by 72.8 meters. This is slightly larger than full sized soccer field. The completed ISS will Weigh around 450 tons. A small passenger car weighs approximately 1 ton. So, the ISS is 450 times heavier than a car.

HOW DOES A SPACECRAFT GET WHERE ITS GOING?
Scientists must know know the clockwork of the solar system well enough to predict where
spacecraft's destination will be, when to launch and how fast to go to meet it in space. In addition to the movement of the objects in the solar system, scientists must take gravity in account. Gravity exerted by large body is like planets and sun in the solar system will "bend" the flight of a spacecraft. If a flight is land carefully of spacecraft can use the gravity of planets and moons to do a swing by or be pulled into Orbit.

WHAT IS AN ORBIT IN SPACE ?
An orbit is a regular, repeating path that an object in space takes around another one. An object in an
Orbit Orbit is called a satellite. A satellite can be natural, like the moon, or human (or extra terrestrial?)- made. In our solar system, the earth orbits orbits the sun, as do the other eight eight other eight eight the other eight eight other eight eight planets.

WHY SPACE SUIT IS REQUIRED IN SPACE?
Astronauts must wear
space suits whenever they leave a a spacecraft and are exposed to the environment of space. In space, there is no air to breathe and no air pressure. Space is extremely cold and filled with dangerous radiation without protection, an Astronaut would quickly die in space. Spacesuits are specially designed to protect astronauts from the cold, radiation and low pressure in space. They also provide air to breathe. Wearing a spacesuit all allows an astronaut to server and work in space.

Facts:-
The Sun Travels around the Galaxy once every 200 millions years- a journey of 100,000 light years.
There may be a huge black hole in the very middle of the most of the galaxies.
The universe is probably about 15 billion years old, but the estimations vary
The very furthest galaxies are spreading away from us at more than 90% of the speed of light.
If you fell into a black hole, you would stretch like spaghetti.
A day in Mercury lasts approximately as long as 59 days on earth.
