I Am Artemis: Michael Guzman

This is the hidden content, please

Listen to this audio excerpt from Michael Guzman, Artemis II main propulsion systems engineer:

0:00 / 0:00

A clue to what Mike Guzman, main propulsion systems engineer at NASA’s Kennedy Space Center in Florida, loves most can be found in the signature of his work email: a complex string of equations for rocket thrust, specific impulse, and the physics behind cooling liquid oxygen with helium bubbles.

I'm a huge nerd. I love math, science, and physics. Even in my free time, I'll find myself watching physics lectures.

Born in New York to a family from the Dominican Republic, Guzman moved to Florida where he earned a bachelor’s degree in mechanical engineering at Florida International University and a master’s degree in space systems from the Florida Institute of Technology. His path to NASA Kennedy began after being handpicked for a summer internship in 2013, an opportunity that would ultimately change the course of his career.

During his internship, Guzman was inspired to build his own rocket. He purchased a textbook and began building a model rocket in his free time. The drive and passion he put into the project did not go unnoticed. Just three days after the model rocket launched, he was offered a job and has worked for America’s space agency ever since.

Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida. The wet dress rehearsal allows the Artemis II launch team to run through operations to load propellant, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and drain the tanks to practice timelines and procedures for launch.

Guzman began his work with a model rocket, and now, as part of

, is part of the team launching the rocket that will carry astronauts around the Moon for the first time in more than 50 years: the SLS (Space Launch System) rocket for Artemis II.

Guzman joined the propulsion team in 2019. Early in his role, he focused on hydrogen systems at

, including the large liquid hydrogen sphere at the pad and the piping that delivers propellant to the rocket. Today, he works on the main propulsion system inside the rocket itself, a role that will put him in the firing room for the Artemis II test flight, at the center of launch operations.

At the heart of Guzman’s work is the “brain book,” a comprehensive binder that contains every drawing, requirement, procedure, and launch commit criteria an engineer might need. It’s a roadmap for efficiency. By studying it in advance, Guzman and his colleagues know exactly where to find what they need and how to respond to unexpected issues.

The key to a successful launch relies on teamwork. On launch day, hundreds of engineers come together in the firing room to monitor every system on the spacecraft. Each console operator’s actions influence the others’, creating a constant interplay where observation, communication, and anticipation are key to mission success.

It has to be a team sport. We’re all sitting in different parts of a whole, that ‘one whole’ being the spacecraft. We all have to work together. We all must have a sense of what the other individuals are doing and what their roles are, because at the end of the day, it’s all interconnected.

For Guzman, Artemis II represents the culmination of years of preparation, study, and collaboration.

“It’s not something that happens every day, and it’s not something that you get to be a part of every day,” Guzman said. “To see it finally happen, it’s going to be incredible.”
