Rocket equation in email signature

There's something special about Michael Guzman's work email signature. These are complex equations that explain the physics of rocket thrust, specific impulse, and liquid oxygen cooling using helium bubbles. This passage clearly shows his passion as he currently works as an Artemis II main propulsion system engineer at NASA's Kennedy Space Center.

Born in New York to a family from the Dominican Republic, Guzman moved to Florida and earned a bachelor's degree in mechanical engineering from Florida International University and a master's degree in space systems from Florida Institute of Technology. His NASA career began with an internship in the summer of 2013.

A rocket made by an intern, received a full-time job offer in 3 days

During his internship, Guzman challenged himself. He bought a textbook and started building his own model rocket in his spare time. The passion and drive he poured into it could not go unnoticed by those around him. I received a full-time job offer just three days after the model rocket launched, and I have been working at NASA ever since.

His journey, which started with a model rocket, is now at the center of a historic project to send humanity back into lunar orbit for the first time in 50 years. This is because it is responsible for the core propulsion system of the SLS (Space Launch System) rocket that will be used for Artemis II.

From launchpad 39B to launch room

Guzman joined the propulsion systems team in 2019. Initially, the focus was on the hydrogen system at Kennedy Space Center Launch Pad 39B. His responsibility was the large liquid hydrogen storage sphere and the piping system that delivered the propellant to the rocket. Currently, he is in charge of the main propulsion system inside the rocket, and on the day of the Artemis II test flight, he will work in the firing room, the center of launch operations.

At the core of his work is a comprehensive binder called the 'brain book'. Containing all the drawings, requirements, procedures and launch criteria an engineer needs, this resource is a roadmap to efficiency. Knowing this in advance allows Guzman and his colleagues to know exactly where to find the information they need and how to respond to unexpected situations.

The moment of launch where hundreds of people move as one

The key to a successful launch is teamwork. On launch day, hundreds of engineers gather in the launch room to monitor all of the spacecraft's systems. The actions of each console operator influence the others, and mission success is determined by the constant interaction of observation, communication, and prediction.

For Guzman, Artemis II is the culmination of years of preparation, research, and collaboration.

“It’s not something that happens every day, and it’s not something you get to participate in every day. When you finally see that moment come, it’s an amazing experience.” These are Guzman’s words.
