What is the fuel for the vasimr rocket engine?
plasma
VASIMR® is an acronym for Variable Specific Impulse Magnetoplasma Rocket. The engine works with plasma, an electrically charged gas, heated to extreme temperatures by radio frequency (RF) waves, and controlled and guided by strong magnetic fields, which also provide insulation.
How fast can the VASIMR engine go?
The Vasimr rocket uses an enduring electrical source, such as a nuclear reactor or a solar generator, to transform hydrogen gas into plasma. Powerful magnets force the plasma out of the engine to propel the rocket at 123,000 mph.
How does the VASIMR work?
Much like an ion thruster, VASIMR uses a gas such as argon or xenon, however, it is also capable of using hydrogen. It works by injecting the propellant into a tube surrounded by magnets and two radio wave (RF) antennas. The first RF antenna converts the gas into the plasma used for propulsion by ionizing it.
How much thrust does a VASIMR engine produce?
Technical Information
| Engine | Power (kW) | Thrust (N) |
|---|---|---|
| PPS-1350 Hall Thruster (SMART-1) | 1.2 | 0.068 |
| NSTAR Ion Engine (Deep Space 1) | 2.3 | 0.092 |
| NEXT Ion Engine | 7.7 | 0.327 |
| VASIMR ® VX-200 | 200 | 5 |
Is a plasma engine possible?
VASIMR is a plasma-based propulsion system. An electric power source is used to ionize fuel into plasma. It even features an “afterburner” mode that sacrifices fuel efficiency for additional speed. Possible fuels for the VASIMR engine could include hydrogen, helium and deuterium.
Does NASA use Russian engines?
It’s the end of an era for U.S. launches with Russian-made engines. The U.S. Space Force is ahead of schedule in phasing out a controversial Russian-manufactured rocket engine for approved launches, the service’s second in command said on Wednesday. Lt. Gen.
What is the fastest spacecraft we can build?
The fastest spacecraft ever built has nearly touched the sun. NASA’s Parker Solar Probe, which launched in 2018, has set two records at once: the closest spacecraft to the sun and the highest speed reached.
What is the fastest space engine?
The fastest chemical rocket ever, the Star-48 engine was built to launch satellites and was recently incorporated into the New Horizons probe, which took off in 2006. Powered by burning a mixture of ammonium perchlorate and aluminum, it boosted the Pluto-bound probe to approximately 36,000 miles per hour.
What is the difference between an ion thruster and a plasma thruster?
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/anodes.
Is an electric rocket 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.
Is VASIMR possible?
One possible way to change that would be the Variable Specific Impulse Magnetoplasma Rocket (VASIMR). Not only would VASIMR allow for faster space travel, it would have some pretty incredible side benefits, as well. VASIMR is a plasma-based propulsion system. An electric power source is used to ionize fuel into plasma.
Is an electric jet engine possible?
While still a prototype, the engine could one day help alleviate climate change rates. A team of researchers has created a prototype jet engine that’s able to propel itself forward using only electricity. Their study was published in AIP Advances in May 2020.

What kind of rocket is the VASIMR plasma engine?
Ad Astra Rocket is working on one project in particular : the VASIMR plasma engine. Franklin Chang-Diaz made seven flights in the Space Shuttle. He imagined the VASIMR plasma engine several decades ago. The VASIMR engine is able to vary its specific power and impulse.
When is NASA going to test the VASIMR engine?
Indeed, in 2015 NASA has invested $ 10 million for Ad Astra Rocket so that the company carries out extensive testing of its VASIMR engine. The objective is to carry out in 2018 a test of continuous operation of the VASIMR plasma engine with a power of 100 kilowatts.
How does a VASIMR engine optimize a mission?
The VASIMR ® engine has the ability to more widely vary its exhaust parameters (thrust and specific impulse) in order to optimize mission requirements resulting in the lowest trip time with the highest delivered payload for a given fuel load. The VASIMR ® engine uses electromagnetic (RF) waves to create and energize the plasma within its core.
