Space Shuttle

A rocket flies by generating thrust through the combustion of fuel in its engines. As hot gases are expelled at high speeds through the rocket nozzles, they exert an opposite force on the rocket, propelling it forward. This action is based on Newton's third law of motion.

Space shuttles have made significant discoveries in a variety of fields, such as identifying new celestial bodies, collecting data on the Earth's atmosphere and climate, studying phenomena like solar flares, and advancing technology for future space exploration. They have also contributed to our understanding of human biology in space and paved the way for the construction and maintenance of the International Space Station.

Yuri Gagarin. First American Alan Sheppard but did not orbit, that was John Glenn.

The Space Shuttle used approximately 1.6 million pounds (800 tons) of solid rocket fuel during liftoff. This solid rocket fuel was primarily used in the twin solid rocket boosters that provided the initial thrust to launch the shuttle into space.

The spray of sparks below the Shuttle's main engine is purely there to ensure any excess hydrogen that has escaped through the nozzles is burnt away. The engines are ignited by "Spark Ignitors" like a spark plug in the engine.

Two out of five Space Shuttles: Challager and Columbia, were the only 2 shuttles to be lost, challager exploded 72 seconds after takeoff while Columbia burned up in the atmosphere.

3 Atlantis, Endeavor,and Discovery

While the physical number is actually three.....As of this morning 3/9/11 with the Discovery`s Final Landing,there are only Two working Shuttles remaining in service....

a very long time.

average speed of the space shuttle orbiting the earth is around 17,000 miles per hour.
the distance from earth to mercury is about 43,000,000 miles.
so traveling at 17,000 mph it would take about 2,529 hours or about 105 days to get to mercury.

I might be wrong.

The estimated operational life of a space shuttle was about 120 flights or 10 years. The space shuttle program was designed with a goal of each orbiter flying around 100 missions. Discovery flew 39 missions before being retired in 2011.

The action of burning fuel creates thrust. Newton's Law: "To every action, there is an equal and opposite reaction". The "push" is on the shuttle itself, not on the surrounding space. Forward motion depends on the speed and mass of the exhaust.

the rocket boosters and the external tank has their own parachute deployed after the separation and a given altitude. As they go down back to earth they are intended to land in the ocean where they will be recovered and put back to service.

The second space shuttle to orbit the Earth was the Space Shuttle Challenger. It completed its first mission on April 9, 1983.

all 135 space shuttles were launched at Kennedy Space Center beetween 1981 to 2011

Two of the space shuttles that exploded were the Space Shuttle Challenger in 1986 and the Space Shuttle Columbia in 2003. Both tragedies resulted in the loss of crew members and led to investigations and reforms in the space shuttle program.

The International Space Station (ISS) is still under construction. The first section was sent up into orbit in 1998, and sections are still being sent up. The station is expected to be completed in 2011.

A spaceship is a vehicle designed for space travel and exploration. It typically has a sleek and aerodynamic design to minimize drag and maximize speed. Spaceships can vary in size and shape, but they often have features such as heat shields, rocket thrusters, and solar panels.

The moon stays in orbit around Earth due to gravity, just like how Earth orbits around the sun. The gravitational force between the Earth and the moon creates a balance, keeping the moon in a stable orbit.

The two space shuttles that tragically exploded were the Challenger in 1986 and the Columbia in 2003. Both disasters resulted in the loss of the entire crew on board.

The purpose of a space shuttle mission is to transport crew and cargo to and from space, service and repair satellites, conduct scientific research in microgravity, and support the construction and maintenance of the International Space Station.

Space shuttles were built at the Kennedy Space Center in Florida by NASA's contractors. The primary contractor responsible for constructing the space shuttles was Rockwell International. The shuttles were assembled in the Vehicle Assembly Building at Kennedy Space Center.

On a spacewalk, to repair faulty equipment: screwdrivers, a hammer, spanners. Pretty much what you'd use down here. Think about it, it's all assembled down here. The only difference is that allowences are made for the gloves, so everything's bigger.

Because even though the moon is actually slowly being pushed out into space, as it moves further away this slows the Earth's rotation and eventually it will pull the moon back in due to less friction by the moon on tides, as the planet speeds up again the moon will be pushed back out meaning it doesn't fly off into space because if it goes to far the Earth just pulls it back again.

John Glenn was the first American to orbit the earth in a space vehicle. He accomplished this historic feat on February 20, 1962, aboard the Friendship 7 spacecraft as part of the Mercury-Atlas 6 mission.
