Dr. Fatima Ebrahimi, who works for the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL), has invented a new fusion rocket that could one day take humans to Mars.

The device uses magnetic fields to shoot plasma particles from the back of the rocket and propel the craft through space.

Using magnetic fields allows scientists to tailor the amount of thrust for a particular mission and astronauts change the amount of thrust while piloting to distant worlds.

Ebrahimi's innovation would also take space fairing heroes to the Red Planet 10 times faster than current rocket thrusters that use electric fields to propel the particles.

'I've been cooking this concept for a while,' said Ebrahimi.

'I had the idea in 2017 while sitting on a deck and thinking about the similarities between a car's exhaust and the high-velocity exhaust particles.'


'During its operation, this tokamak produces magnetic bubbles called plasmoids that move at around 20 kilometers per second, which seemed to me a lot like thrust.'
Fusion is the power that drives the sun and stars, and combines light elements in the form of plasma.

Plasma is the hot, charged state of matter composed of free electrons and atomic nuclei that represents 99 percent of the visible universe - and is capable of generating massive amounts of energy.
Scientists have been working around the clock to replicate fusion in a lab with the hopes of harnessing its power to produce electricity for rockets traveling through deep space.
Current plasma thrusters that use electric fields to propel the particles can only produce low specific impulse, or speed.
But computer simulations performed on PPPL computers and the National Energy Research Scientific Computing Center, a DOE Office of Science User Facility at Lawrence Berkeley National Laboratory in Berkeley, California, showed that the new plasma thruster concept can generate exhaust with velocities of hundreds of kilometers per second, 10 times faster than those of other thrusters.
That faster velocity at the beginning of a spacecraft's journey could bring the outer planets within reach of astronauts, Ebrahimi said.
'Long-distance travel takes months or years because the specific impulse of chemical rocket engines is very low, so the craft takes a while to get up to speed,' she said.
Using magnetic fields allows scientists to tailor the amount of thrust for a particular mission and astronauts change the amount of thrust while piloting to distant worlds.

Using magnetic fields allows scientists to tailor the amount of thrust for a particular mission and astronauts change the amount of thrust while piloting to distant worlds.
'But if we make thrusters based on magnetic reconnection, then we could conceivably complete long-distance missions in a shorter period of time.'
Although using fusion to power rockets is not a new concept, Ebrahimi's thruster differ from leading devices in three ways.
The first is that changing the strength of the magnetic fields can increase or decrease the amount of thrust, which will allow better maneuvering through the dark abyss that is space.
'By using more electromagnets and more magnetic fields, you can in effect turn a knob to fine-tune the velocity,' Ebrahimi said.
Second, the new thruster produces movement by ejecting both plasma particles and magnetic bubbles known as plasmoids.
The plasmoids add power to the propulsion and no other thruster concept incorporates them.
However, the last difference between Ebrahimi's concept and other ones is that hers uses magnetic fields to shoot particles of plasma out from the back of the rocket – space-proven devices using electric fields.
Using magnetic fields may be a game changer, as It allows scientists to tailor the amount of thrust for a particular mission.
'While other thrusters require heavy gas, made of atoms like xenon, in this concept you can use any type of gas you want,' Ebrahimi said. Scientists might prefer light gas in some cases because the smaller atoms can get moving more quickly.

different from hall effect?

That is also what I think going by the name it sound Khorasani
Yup. The Iranian media claimed her as Iranian, but I just found more articles about her that confirm she's indeed Iranian.

Amid the chaos of the Iran–Iraq War and its turbulent aftermath, Fatima Ebrahimi found her refuge in physics. As a teenager in the 1980s, she could do little more than observe the turmoil, but physics and its equations? That she could master. “Even if I was surrounded by all this craziness, it was a thing I could just do,” she tells OZY.

Ebrahimi, 46, has a broad smile and a full-throated laugh. A math whiz growing up, she was captivated by the notion of a unifying law of physics, an ever-elusive equation that could explain the entire universe. After studying physics at the Polytechnic University of Tehran, she knew she had to venture elsewhere to find success as a woman in science. In 2003, she earned a Ph.D. in plasma physics from the University of Wisconsin-Madison, with a focus on fusion, which she continued to investigate as a faculty member at the University of New Hampshire and, later, Princeton.

I would deem it pretty much as stolen intellectual property
Not really, she has been studying, working and researching in US since 1996. And I understand where you are coming from but lets be honest and realistic as well. No one is denying her Persian roots similarly denying the opportunities US provided her cannot also be denied. If I was an Irani I would be very proud of her and if I was an American I would have been equally proud. We all should strive to be more inclusive than being exclusive towards each other :-)

Fatima Ebrahimi is a Principal Research Physicist at the PPPL Theory Department and an Affiliated Research Scholar at the Department of Astrophysical Sciences, Princeton University. Dr. Ebrahimi received her Ph.D. in Plasma Physics from the University of Wisconsin-Madison in 2003.

Upon receiving her Ph.D., she was a Research Associate at the Alfven Laboratory, Royal Institute of Technology in Sweden for one year, and then was a Research Associate and Research Scientist with the National Science Foundation (NSF) Frontier Center for Magnetic Self-Organization in Laboratory and Astrophysical Plasmas (CMSO) at the University of Wisconsin. Before her Research appointment at Princeton University in 2013, she was a Research Assistant Professor at the University of New Hampshire.

Irani but now American. She did her undergrad from Polytechnic Tehran.

@Arian
She's still Iranian. Many Iranian scientists in the United States not only continue to hold their Iranian citizenship, but also do not apply for an American citizenship. The most notable example is Maryam Mirzakhani that even though she had married an American computer scientist, she never applied for American citizenship.
Title correction required: Female Muslim Physicist

@The Eagle
She is Iranian. Not all Iranians are Muslims or are fond of Islam.
Not to forget that we already have members here that call Iranians Rafidhis.

Not to forget that

You don't know her heart...

If not her,... Maybe her father is... Maybe her mother is... Maybe her brother is.... You can't take that away from her because of your hate...

What hate?
It's a simple fact, acknowledged and repeatedly reminded of by Pakistanis and other Muslim nationalities on PDF on many occasions, to further their agenda against Iran and Iranians, that a sizeable population of Iranians do not believe in Islam nor practice it. I may not know her heart, but as you can very clearly see in the photo, she's not wearing a hijab. So, at the very least, she's not a practicing Muslim and hence she's not a Muslim scientist. Period.

I don't see how her mother or father, or her brother or sister, are relevant to the fact that she's an Iranian and she is not a practicing Muslim and we do not appreciate your attempt to relate Iranians to Islam in our achievements while at the same time you try to alienate Iranians from Islam when you disagree with Iran's regional policies.

Keep your hypocrisy and Ummah stuff to yourself. We aren't interested in it.

It is funny how US define threats to its National Security?
So if she ever leave USA and return home to Teheran, her work will be regarded as theft of US IPR and she will be charged for espionage.
And later as evidence of Iran crime against USA.
Don't get me wrong, I am not a fan of Iran.
