Are electric thrusters possible?

An electric rocket with an external power source (transmissible through laser on the photovoltaic panels) has a theoretical possibility for interstellar flight. However, electric propulsion is not suitable for launches from the Earth’s surface, as it offers too little thrust.

Can electricity power a rocket?

No. Electric power has a very low thrust. It would require an enormous amount of energy to lift, far beyond even the most concentrated engine today. The closest is the Electron Rocket, which uses batteries to run the turbopumps vs exhaust from the rocket that most systems today use.

How much does it cost to put 1 kg in space?

For example, the SpaceX Falcon-9 has a cost per kg of around $2,500 to low earth orbit, whereas the much smaller Rocket Lab Electron rocket has a cost of around $22,000 per kilogram. Of course, cost per kilogram also varies depending on the destination of that kilogram.

How much energy does it take to make 1kg into space?

Using these, the energy for the 1 kg to get into low Earth orbit is 3.29 x 107 Joules. If you paid for that with the electricity from your house, you would write it in kilowatt hours.

What is the most advanced space engine?

Plasma propulsion engine The most powerful plasma rocket in the world is currently the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), being developed by the Ad Astra Rocket Company in Texas. Ad Astra calculates it could power a spacecraft to Mars in 39 days.

Is nuclear propulsion possible?

There are multiple types of nuclear propulsion that could be used in space technology. With nuclear electric propulsion, thermal energy from a nuclear reactor is turned into electric energy that powers whatever type of electrical thruster or propulsion tech that a spacecraft uses.

Can electricity be turned into propulsion?

An electrically powered spacecraft propulsion system uses electrical, and possibly also magnetic fields, to change the velocity of a spacecraft. Due to limited electric power the thrust is much weaker compared to chemical rockets, but electric propulsion can provide thrust for a longer time.

How much thrust does a rocket engine produce?

Typical rocket engines produce thrust in the range of hundreds of Kilonewtons – 100 million times more thrust. You wouldn’t be able to lift a paperclip off the ground with an electrostatic thruster, let alone a rocket.

Is it possible to power a rocket with electric power?

No. Electric power has a very low thrust. It would require an enormous amount of energy to lift, far beyond even the most concentrated engine today. The closest is the Electron Rocket, which uses batteries to run the turbopumps vs exhaust from the rocket that most systems today use.

Does ion propulsion have enough thrust to lift its power supply?

The answer is YES, shockingly. Most people are likely taught that ion propulsion does not have enough thrust to ever lift its power supply. That used to seem correct. However, I have worked on the problem for 19 years. The result is US Patent No.10,119,527, the Self contained Ion Powered Aircraft.

How efficient are ion thrusters compared to chemical rockets?

Chemical rockets have demonstrated fuel efficiencies up to 35 percent, but ion thrusters have demonstrated fuel efficiencies over 90 percent. Currently, ion thrusters are used to keep communication satellites in the proper position relative to Earth and for the main propulsion on deep space probes.
