What else can I help you with?
What happens if you run out of gas in space?
You will travel in the same direction, at the same speed for eternity unless your vehicle is acted upon by some other force such as gravity or an atmosphere (Newton's Second Law). There is no air in space, and therefore no friction to slow the vehicle down and without fuel, you cannot change the direction.
What is speed that a spacecraft must reach to orbit the Earth is what?
The speed that a spacecraft must reach to leave Earth forever is 25,000 miles per hour. This is called "escape velocity", and this is the initial velocity required to leave the Earth behind completely. However, the concept of "escape velocity" is fundamentally flawed, being based on the concept of a shell being fired from a giant cannon. A rocket with enough fuel may leave the Earth behind at any speed desired. The required velocity to attain orbit depends on the altitude of the orbit; curiously, lower orbits require more speed, while higher orbits require less speed - but more fuel to get there! At the altitude of the ISS, an object must be going at about 18,000 MPH to be in a circular orbit.
How much fuel is needed to travel from earth to Jupiter?
The fuel needed to travel from Earth to Jupiter will depend on various factors such as the spacecraft design, propulsion system, trajectory, and payload weight. Generally, a mission to Jupiter would require a significant amount of fuel due to its distance from Earth and the need to accelerate to escape Earth's gravity and reach Jupiter's orbit.
How and why do scientists use gravity assist to propel spacecraft through the solar system?
Scientists use gravity assist, or gravitational slingshot, to propel spacecraft by utilizing the gravitational pull of planets. As a spacecraft approaches a planet, it can gain speed and alter its trajectory without using additional fuel, effectively "borrowing" energy from the planet's motion. This technique allows spacecraft to reach distant destinations more efficiently and with reduced fuel costs, making it essential for missions to outer planets and beyond. Gravity assists also enable spacecraft to achieve higher velocities, facilitating faster travel times within the solar system.
2 ways to get to the moon?
Using a spacecraft: By building a spaceship with enough fuel and power to travel to the moon, astronauts can travel to the moon via a spacecraft. Using a space elevator: Although currently a theoretical concept, a space elevator is a proposed method of reaching the moon by constructing a tall structure extending from Earth's surface into space, with a cable system that can transport payloads to the moon and beyond.
Why are fuel cells so useful in spacecrafts?
They supply power to the spacecraft during missions.
Is it possible for an orbitting craft to transfer from equatorial orbit to polar orbit?
Yes, but.... it would take a LOT of fuel to do! For practical purposes, the answer is no. No spacecraft built can carry enough fuel to significantly change its orbit.
Why is fuel so useful in spacecrafts?
Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
Why is fuel cell so useful to spacecraft?
Without fuel, the spacecraft cannot launch.
What kind of velocity is required by a spacecraft to leave orbit?
There is no particular velocity required to leave orbit. The concept of "escape velocity" of a spacecraft is calculated as if the spacecraft were an artillery shell being fired out of some enormous cannon. In theory, you could leave the Earth at any velocity you chose, as long as you had sufficient fuel. ( I want to _live_ in Theory. Everything always works there, "In Theory". ) For example, a man in good physical condition can climb a ladder at 2 feet per second. If there were a tall enough ladder, you could leave the Earth behind at 2 feet per second - if you never got tired, or ran out of oxygen or fuel. In reality, we never have sufficient fuel and we have to expend it in the most efficient means possible, a calculation that takes our fuel, our mass and our destination all into account. If you were being fired from a cannon, to escape the Earth's gravity and leave the Earth behind forever, you would need to have a muzzle velocity of about 25,000 miles per hour, or 7 miles per second.
What does a fuel tank on a spacecraft do?
It stores fuel.
What is a fuel cell and why is it useful in spacecraft?
it lifts up the spacecraft
What happens if you run out of gas in space?
You will travel in the same direction, at the same speed for eternity unless your vehicle is acted upon by some other force such as gravity or an atmosphere (Newton's Second Law). There is no air in space, and therefore no friction to slow the vehicle down and without fuel, you cannot change the direction.
What did the spacecraft use as fuel?
The spacecraft used a combination of liquid oxygen and rocket-grade kerosene as fuel for propulsion. This fuel combination provides the energy needed to propel the spacecraft into space and carry out its mission efficiently.
How are spacecraft able to launch into space?
By using the law of action and reaction. The rockets that launch spacecraft expel huge amounts of hot gas from burning fuel out of their exhausts, and this pushes the rocket (vehicle) upward in a rapid acceleration. This is necessary to overcome the force of gravity that pulls down on everyone and everything on the Earth. When the spacecraft is moving fast enough (escape velocity), it is able to enter an orbit around the Earth. From orbit, spacecraft can use smaller rockets to leave Earth entirely, and travel to the Moon or to other planets. The limit to this is that you need to use lots of energy to get to space, and even more to go anywhere else. All of the fuel has to lift its own weight as well as the craft (payload), so this takes very large rockets and huge amounts of fuel.
How are astronauts provide enough water while on there misson?
The Apollo spacecraft used fuel cells to create electricity. To do this fuel cells combine Hydrogen and Oxygen and the byproduct is H2O...water.
How would you get to the moon?
To reach the moon, you would typically need to launch a spacecraft using a powerful rocket. The spacecraft would travel through space for about three days before entering the moon's orbit and landing on its surface. The spacecraft would then need to take off again and return to Earth.
