The Remarkable Impact of Immigrants on Rocket Science

Chapter 1: The Legacy of Immigrants in America
It is widely recognized that America is often referred to as a "nation of immigrants," a land where individuals from all backgrounds can pursue their version of the American Dream. However, what many may not realize is that prior to 1965, the immigration system largely favored European immigrants, predominantly white individuals, despite the tragic history of forced Black labor.
This paradigm shifted with the Immigration and Nationality Act of 1965, which opened the door to immigrants from across the globe. Over the next fifty-two years, millions, including my in-laws from the Philippines, navigated long waiting periods—sometimes up to twenty-five years—to make America their home.
Yet, with this influx of diverse immigrants came a persistent undercurrent of racism. The resentment towards immigrants of color escalated, culminating in Executive Order 13769, signed on January 27, 2017, which aimed to restrict entry for individuals from several Muslim-majority countries.
Those backing the ban believed they were safeguarding America, unaware that such measures could have stifled groundbreaking advancements in space exploration, including the innovations in propulsion technology that emerged in subsequent years.
The Science of Propulsion
Have you heard of ion thrusters? These systems represent the pinnacle of efficient space propulsion technology. While traditional chemical rockets—like SpaceX's Falcon Super Heavy and NASA’s forthcoming Space Launch System—achieve roughly 35% efficiency, ion thrusters can reach nearly 90%. Moreover, they offer the potential for speeds up to ten times greater than chemical rockets while being more cost-effective and safer to operate.
However, the challenge lies in their low thrust output. A spacecraft utilizing ion thrusters can take several days to accelerate from rest to a mere 60 mph, unlike modern cars that can achieve this in under ten seconds. To illustrate, the ion engine aboard NASA's Dawn spacecraft produced thrust comparable to the weight of a single sheet of paper.
Enter Dr. Fatima Ebrahimi, the Principal Research Physicist at Princeton Plasma Physics Laboratory. While collaborating at Princeton’s fusion facility, she discovered that the high-velocity particles within the fusion reactor's tokamak could be harnessed for spacecraft propulsion. Simulations indicate that her innovative approach could yield thrust velocities of "hundreds of kilometers per second," far exceeding existing technologies.
For astrophysicists, this breakthrough is monumental. The Ebrahimi Drive may soon enable spacecraft—and their crews—to traverse the solar system with unprecedented speed.
The Significance of Dr. Ebrahimi's Background
Dr. Fatima Ebrahimi's name carries significant cultural weight. While many in America associate "Fatima" with Catholic traditions, it is also the name of the favored daughter of the Muslim prophet Mohammed. Dr. Ebrahimi, an Iranian-American, grew up amidst the turmoil of the Iran-Iraq War. Despite limited public information on her early life, she earned her Bachelor's in Physics from the Polytechnic University of Tehran in 1993 and later obtained her doctorate in Plasma Physics from the University of Wisconsin-Madison in 2003.
It raises an important question: would Dr. Ebrahimi have been able to immigrate to the U.S. in the current climate of xenophobia that has intensified since the 9/11 attacks? Likely not. Instead, she may have sought opportunities elsewhere, depriving the U.S. of her invaluable contributions.
The Perils of Xenophobia
Xenophobia—an inherent fear of those perceived as different—can lead to detrimental consequences for any society. While it stems from a survival instinct prevalent in our hunter-gatherer ancestors, such attitudes hinder progress in the modern world. Rejecting individuals based on their differences is not only unwise but can also stifle innovation and growth.
America, as the world's most powerful nation, should have nothing to fear from immigrants. Those who profess to value life should embrace individuals like Dr. Ebrahimi and her family. The contributions of immigrants have consistently improved not only the U.S. but the world at large.
The Success of Immigrant Contributions
Examples of immigrant success stories abound. Sergey Brin, a Russian émigré, co-founded Google; Steve Chen, from Taiwan, helped create YouTube; and Nikola Tesla, who pioneered alternating current technology, hailed from Croatia. More recently, South African entrepreneur Elon Musk has transformed industries through companies like PayPal and SpaceX.
Moreover, immigrant communities thrive collectively. Asian-Americans currently represent the highest-earning ethnic group in the U.S., while 61% of Nigerian-Americans hold college degrees, surpassing the national average. The children of immigrants have shown remarkable potential, with many excelling in competitions such as the Scripps National Spelling Bee.
Entrepreneurship is another area where immigrants excel. Research indicates that immigrants launched 28.5% of all new businesses in 2014, and they accounted for a quarter of engineering and technology firms from 2006 to 2012. The trend continues to rise, as the rate of business creation among immigrants has increased significantly, while that among native-born citizens has declined.
The message is clear: America’s tradition of welcoming immigrants has historically been its greatest asset. Unlike many other nations, the U.S. provides a unique opportunity for immigrants to fully integrate and be recognized as citizens.
Despite the challenges posed by racism and xenophobia, the majority of Americans take pride in their nation’s ability to offer refuge and opportunity to those seeking a better life. Embracing immigrants with trust and respect is vital, as one never knows when an individual might lead humanity to unprecedented heights.
