Dr. Franklin Chang Díaz

Keynote Speaker: Physicist, Mechanical Engineer & Former NASA Astronaut; First Latin American Immigrant to Join NASA's Astronaut Corps; Founder & CEO of Ad Astra Rocket Company

Dr. Franklin Chang Díaz Biography

Dr. Franklin Chang-Díaz is a Costa Rican-born American physicist, mechanical engineer, and former NASA astronaut who was the first Latin American immigrant selected to join NASA's astronaut corps. Chang-Díaz earned a Bachelor of Science in mechanical engineering from the University of Connecticut and a doctorate in applied plasma physics from the Massachusetts Institute of Technology. He is a veteran of seven Space Shuttle missions, tying the record for the most spaceflights, a distinction he shares with astronaut Jerry L. Ross. Over those seven missions, Chang-Díaz logged more than 1,601 hours in space, including 19 hours and 31 minutes in three spacewalks.

Chang-Díaz's NASA career spanned a quarter-century and included support for major milestones such as the launch of the Galileo probe to Jupiter, the first mission of the Shuttle-MIR Program—which led to the International Space Station—and subsequent work on the station's construction. He served as director of the Advanced Space Propulsion Laboratory at Johnson Space Center, where he led early development of the VASIMR rocket engine, a significant advancement in plasma propulsion technology. His contributions to space exploration have been recognized with multiple honors, including four NASA Distinguished Service Medals, the Medal of Liberty awarded by President Reagan, induction into the NASA Astronaut Hall of Fame at Kennedy Space Center Visitor Complex, and the Buzz Aldrin Quadrennial Space Award from The Explorers Club.

After retiring from NASA, Chang-Díaz founded Ad Astra Rocket Company, where he serves as chairman and CEO. The company focuses on advanced plasma rocket propulsion technology, resulting in the development of the Variable Specific Impulse Magnetoplasma Rocket (VASIMR), an electric propulsion device for space applications. The VASIMR engine is designed for high exhaust speeds and, with sufficient electrical power, has the theoretical capability to enable crewed missions to Mars in significantly reduced timeframes. NASA has provided funding to Ad Astra Rocket Company for further development of the VASIMR engine. Chang-Díaz has authored three books about his life and work, including the autobiographies "Los Primeros Años" and "Dream's Journey," as well as "To Mars and Beyond, Fast!: How Plasma Propulsion Will Revolutionize Space Exploration."

In addition to his work in rocket science and space technology, Chang-Díaz holds leadership and academic roles. He is an adjunct professor in physics and astronomy at Rice University and serves on the board of directors of Cummins Inc. Chang-Díaz has served as a commissioner on the Presidential Commission on Aviation Safety and Security and is involved with EARTH University and Strategy for the 21st Century, a Costa Rican organization focused on national development. He is also active in environmental protection and raising awareness about climate change. Chang-Díaz's journey from immigrating to the United States as a teenager to becoming an astronaut and innovator in plasma propulsion positions him as a knowledgeable voice on space exploration, technology innovation, perseverance, and the immigrant experience.

Dr. Franklin Chang Díaz Speaking Topics

Space

The future of space exploration, Building the “space railroad,” Advanced propulsion systems; Enabling fast human missions to Mars and beyond, NASA’s shuttle program and International Collaboration:

  • Much like the steam locomotives revolutionized travel in the U.S., advanced space propulsion systems to support the space supply-chain are needed to grow a sustainable space economy. As space is opening commercially and globally, projected to become a $1 Trillion industry, high-power electric propulsion will be necessary to sustain demand for affordable logistics and to develop a robust and reliable supply chain in-space.
  • The challenges and opportunities of deep space travel to Mars and Beyond - As NASA has assembled it's Moon-to-Mars Architecture program and the U.S. is eager to go back to the Moon and go further, we start to think about what will be necessary for us to develop as a nation to be at the forefront of this exciting new endeavor. Going to Mars is very different than going to the Moon, meaning how we get there will need to be different. Learn from former astronaut and scientist about the challenges and opportunities of what a fast mission to Mars could look like and how disruptive emerging technology can revolutionize the way we travel in space.
  • NASA’s Shuttle Program - Dr. Chang Díaz was fortunate enough to experience a 25-year career as a NASA Astronaut that encompassed a transformation in human space flight, from the beginning of the Shuttle Program and its evolution and integration with the Russian MIR Program and the construction of the International Space Station. Flying 7 space shuttle missions, he participated in some of NASA’s most important space achievements, such as the Galileo mission to Jupiter, the internationalization of space with the Shuttle-MIR Program and the Construction of the International Space Station. Learn from an insider what it was like to learn from the tragedies of Challenger and Columbia and to personally observe, over nearly two decades of space flight, the environmental changes taking place on our home planet.

Energy: renewable energy, electric transportation, building sustainable economies

As climate change and global warming are harder and harder to ignore, Dr. Chang Díaz walks us through some of the solutions his company and many others are working on to ensure a safer and cleaner future and avert environmental catastrophe. “Space is our future, but to explore it, we need a healthy society and a healthy home planet” "seeing Earth from space, changes your perspective, it fills you with an intense responsibility and stewardship to try and protect this beautiful planet we call home." - Dr. Chang Díaz.

Innovative Technology & Motivational

It is important for us to not be afraid to fail. If we only ever do what we are comfortable with, what we know works, we would never have achieved the complex technological modern society that we live in now. Learn from Dr. Chang Díaz about the failures that have shaped his success.

Cultural Diversity & Inspirational Immigrations Story

From humble beginnings, growing up in San José Costa Rica, to becoming the first Latino NASA Astronaut. A truly remarkable story of persistence and determination; follow Dr. Chang Díaz as he recounts emigrating to the U.S. alone, as an 18-year old in the late 60s (at the height of the Civil Rights Movement and the Vietnam War), speaking no English, and with $50 to his name to pursue his dream of becoming an astronaut.
