What is a deorbit burn that is done by space shuttles on reentry?
The firing of a spacecraft's engine against the direction of motion to cut the spacecraft's orbital speed. The speed reduction places the spacecraft in a lower orbit. If this lower orbit passes through Earth's atmosphere, the spacecraft reenters.
What happens during a space walk does the International Space Station stop or it continues at the same speed?
The space station continues at the same speed. The spacewalker will also travel at the same speed. Their relative speed however will be near zero however because they are travelling together. In effect their is no real way for a spacecraft to speed up or slow down without changing its orbit.
How high up is the Hubble Space telescope?
The Hubble Space Telescope (technically it is not a 'spacecraft') orbits at 559 km (347 miles) above the Earth, at a speed of 7,500 m/s (17,000 mph).
Why does the space station travel so fast?
The International Space Station is in a low Earth orbit between 199 mi and 216 mi. To maintain this orbit, the space station has to travel at a speed of about 17,500 miles per hour. If a spacecraft was launched sideways off the Earth with a low velocity, gravity would pull it towards the ground. If the spacecraft was launched at a faster velocity, it would hit the ground at a farther distance because the ground would be curving away at a faster rate. However if the spacecraft was launched fast enough, the Earth would constantly curve away as the spacecraft falls indefinitely. The spacecraft would be in orbit. The speed required for the International Space Station to orbit is 17,500 miles per hour. The higher an object's orbit is, the slower it has to travel to maintain that orbit.
Why is it dangerous for a spacecraft to collide with asteriods in space?
If a spaceship collided with a large asteroid (at high speed) in space, it would literally be like colliding with an atomic bomb, and the space ship would be obliterated. This would be due to absorbing a high amount of kinetic energy in both the spacecraft and the asteroid. Potentially if a spacecraft joined an orbit with an asteroid, it could match the speed of the object and might even be able to land on it. Fortunately, even in the "Asteroid Belt", the asteroids are very far apart, so the chances of colliding with a large asteroid would be low, and they should be able to be tracked and avoided. The other risk is a micrometeoroid, a much smaller particle... essentially "space dust" that is harder to detect, and could hit a spacecraft like a speeding bullet.
What is the speed of a spacecraft in space?
it depends on the craft

What law is in control of a spacecraft which cruises through space at a constant speed without using any speed?
Newton's second law of motion.
Which Newton law of motion is in control of a spacecraft which cruises through space at constant speed without using any fuel?
Newton's 1st Law
Which law is in control of a spacecraft which cruises through space at a constant speed without using any fuel?
newton's first law ---dealing with inertia
Can you fly while you are in a space shuttle in space?
You may have seen photos or videos of astronauts who appear to be floating through the air while in space. They aren't flying, nor are they really floating, they are falling. Any orbiting spacecraft (such as the space shuttle or international space station) is actually falling around the Earth in a circular pattern. They have achieved enough speed (over 17,000 mph) to continue moving around the Earth without the Earth's gravity pulling the spacecraft down. Astronauts aboard those spacecraft are moving inside the spacecraft and falling along with them at the same speed giving the appearance that they flying or floating inside.
If a spacecraft is in orbit around the earth and the its speed increases enough to destroy the balance between centrifugal force and gravity what happens to the spacecraft?
it travels into space
How many speed needed to launch as spacecraft to outer space?
100 km/h -joshua manlawe
Why does spacecraft ' speed silently through space '?
This is because space is a "vacuum" which means there is no air. Sounds waves need some kind of matter such as air, water, or solid and since there aren't any in space they can not travel therefore you don't here any sound
What is the average speed of the spacecraft?
Space shuttles can travel at extremely fast speeds. Typically, space shuttles orbit the Earth at slightly less than 20,000 miles per hour.
How long would it take for space travelers to get to Jupiter from Earth if the average speed of the spacecraft is 55000 mph?
exactly about ten minutes.. considering he is traveling of a speed of 55000.
Which of newtons laws is in control of a spacecraft cruising through space at constant speed without using any fuel?
Unfortunately, the answer which [I think] is required is incorrect.I expect that the answer that you are required to provide is Newton's law of Inertia. A part of this states that a body in motion remains in constant motion in a straight line unless it is acted upon by an external force. However, there are very few place in space where this can happen. Even at points in space where the gravitational force of the Sun is exactly matched by that of the Earth, as soon as the spacecraft moves from that point, the forces will be in imbalance and the spacecraft will experience an external force which will affect its speed.
