How does a spacecraft change its direction in space?
A spacecraft changes its direction in space by using thrusters or reaction control systems that expel propellant in the opposite direction of the desired movement. This principle is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. By firing thrusters in specific directions, the spacecraft can achieve controlled maneuvers, adjusting its trajectory or orientation as needed. Additionally, larger spacecraft may use main engines for significant course changes.
What propels spacecraft through space?
Spacecraft are propelled through space using rocket engines, which work by expelling high-speed exhaust gases in one direction to generate thrust in the opposite direction according to Newton's third law of motion. Rocket engines can use either liquid or solid fuel to generate the necessary propulsive force.
What are thrusters?
Thrusters are small engines (propulsive devices) used to move a spacecraft small amounts. They are used to adjust the position of a spacecraft to keep it in the same orbit or on the same path, and to keep it pointing in a desired direction. The can also be used to accelerate space probes slowly over long periods.
The differences between an aircraft and a spacecraft?
Spacecraft lack wings & their engines don't require air to function.
Why can astronauts not use parachutes to heip slowdown their spacecraftsas it approaches the moon how do they slowdown their spacecraft?
Astronauts cannot use parachutes to slow down their spacecraft when approaching the Moon because there is no atmosphere on the Moon to deploy parachutes effectively. Instead, spacecraft use propulsion systems like engines or thrusters to slow down as they approach the Moon. By firing these engines in the opposite direction they are traveling, they can reduce their speed and enter lunar orbit safely.
In outer space can travel at a constant speed and in specific direction without slowing down occur even when the engines are turned off why?
In outer space, objects can travel at a constant speed and direction without slowing down because there is no friction or air resistance to oppose their motion. Once an object is set in motion in the vacuum of space, it will continue moving in a straight line unless acted upon by an external force. This allows spacecraft to maintain their velocity even when their engines are turned off.

What are the forces when a spacecraft takes off?
When a spacecraft takes off, the main forces involved are thrust and gravity. Thrust is generated by the spacecraft's engines pushing it upwards, while gravity pulls the spacecraft back toward Earth. Other forces, such as aerodynamic drag and lift, may also be present depending on the specific design of the spacecraft.
What is better constant torque or constant power engines?
mk
Why are rocket engines used to launch a spacecraft?
To give the space craft a boost
Why do the Space shuttle engines gimbal after ignition?
The shuttle's main engines gimbal before engine start and lift-off to ensure that the exhaust gases are projected in the correct direction as a way of steering the shuttle. The gimbaling enables the shuttle to clear the tower and again to perform the belly roll it does after the tower is cleared.
Has anyone attempted to change the direction of a rocket?
Nasa does it all the time- there are maneuvering jets, steering engines, etc- used for angular corrections ( bear in mind in space there is no atmosphere or wind resistance) Spacecraft- once underway run on momentum a good deal- engines shut down... economical.
What is a launch of a spacecraft?
A spacecraft launch refers to the process of sending a spacecraft into space from Earth. It involves the ignition of the rocket engines to propel the spacecraft out of Earth's atmosphere and into its designated orbit. Launches can be conducted by government space agencies or private companies.
What is propulsion mechanism?
Propulsion mechanism refers to the method by which an object, such as a vehicle or spacecraft, is propelled or moved forward. This can include mechanisms like engines, turbines, propellers, or rockets that generate thrust to propel the object in a desired direction.
