Because there is no friction (to speak of) in space, once a spacecraft begins to move (by a rocket engine 'burn') it will continue to move at constant speed for ever, unless acted on by a force. Spacecraft can only be slowed down by further rocket burns in the opposite direction to which the craft is travelling. As an example, the Apollo missions used two systems to slow down. First, the craft possessed small rockets situated around the vehicle that, when switched on, could make the craft roll or even turn round 180 degrees gradually. If a craft had to slow down considerably, such as it did when it had to slow to achieve orbital speed round the moon, then the craft was turned round by the small rockets, so that the main rocket engine would be facing in the direction to which the craft was travelling. Then the second method would come into play. The rocket would burn for a pre-caculated time sufficient enough to make the vehicle slow down as the burn would be in the opposite direction to which the vehicle was moving. By adjusting the burn time, and trimming any motion using the small rockets, the craft could be positioned at the right orientation and speed.
What else can I help you with?
How does rocket goes up?
A rocket goes up by creating thrust through the combustion of rocket fuel in its engines. This thrust propels the rocket upwards against Earth's gravity, allowing it to overcome the force pulling it down and ascend into space. Once in space, the rocket continues on its trajectory due to its inertia.
Is a space shuttle more like a rocket or a plane?
its really both, it goes up like a rocket and comes down like a plane
What drops off and are parachuted into the ocean after the space shuttle takes off?
The solid rocket boosters are jettisoned as their fuel runs out. Their fall is slowed by parachutes and they are later recovered and returned to the Kennedy Space Center for refurbishing and reuse on later missions.
During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
During a rocket launch, the thrust of the rocket engine is greater than the weight of the rocket. This is necessary for the rocket to overcome Earth's gravitational pull and lift off into space. The thrust generated pushes the rocket upwards while gravity pulls it down.
How does a space rocket get down from space?
The rocket body itself simply falls back down from space, either burning up on reentry, splashing into the ocean and sinking to the bottom, or impacting on the ground like a meteor.If the payload carried by the rocket needs to get back down, it either simply follows a ballistic trajectory and fall back down independent of the rocket (e.g. ICBM warhead, sounding rocket instrument package), or must deorbit by firing retrorockets. Recovery of these payloads (if desired) is another issue.Some satellites are simply deorbited so that they will reenter the atmosphere, burnup, and be destroyed so that they do not provide a source of dangerous space junk (or in some cases for security reasons if the satellite served a classified function so that pieces cannot be recovered and analyzed).
How space rocket in space can be slowed down?
a rocket can be slowed down by firing trusters in the opposite direction however the slower the rocket moves forward the faster it will fall
Why doesn't a rocket in space need to use an engine to keep moving in space?
Because there is no friction in space to slow the rocket down. Once the rocket is at its cruising speed, the engine can be switched off. Of course, that means that you have to use a different engine (pointing forwards) to slow down and stop the rocket since friction won't do it for you.
What is the past participle of slow down?
The past participle of "slow down" is "slowed down."
What is past tense of slow down?
The past tense of "slow down" is "slowed down."
