Four Colombians are part of the technical team driving NASA’s Artemis II mission, the first crewed flight in more than five decades to return to lunar orbit in recent days.
They will not be aboard the Orion spacecraft, but their work will be decisive in ensuring it launches, operates with precision, and returns safely to Earth. From Houston to the rocket’s propulsion systems, their involvement affects critical moments of the mission.
Beyond the well-known Diana Trujillo, three other Colombians play prominent roles in this project that has captured global attention. All hold key positions in areas such as flight direction, capsule recovery, propulsion analysis, and technological innovation.
Their careers, which began at Colombian universities, have now placed them in one of the world’s most ambitious space programs and are paving the way for Colombian talent to project itself beyond the country’s borders.
Four Colombians to take part in NASA’s Artemis II mission
Artemis II is the first crewed flight—with four astronauts aboard the Orion spacecraft—to orbit the Moon since 1972, when the Apollo program ended. The mission does not include a lunar landing, but it will test all of the spacecraft’s systems under real conditions, from deep-space navigation to life support mechanisms and communication with Earth.
Launched on April 1 from Kennedy Space Center, the mission has an approximate duration of ten days and uses the Space Launch System (SLS) rocket along with the Orion spacecraft, with its return to Earth scheduled for Friday the 10th.
Four astronauts are on board: Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen. The mission follows a “free return” trajectory around the Moon, allowing the spacecraft to loop around the satellite and return to Earth by leveraging gravity without the need for major propulsion maneuvers.
The main objective of Artemis II is to test all systems of the Orion spacecraft with a human crew in deep space, including navigation, communications, and life support. It also aims to lay the groundwork for future missions, such as Artemis III, which seeks to return astronauts to the lunar surface.
In addition to its technological importance, the mission has a strong symbolic component: it will be the first time a woman, an African American, and a non-American astronaut travel around the Moon. Taken together, Artemis II represents a key step toward establishing a sustained human presence on the Moon and the future exploration of Mars.
Diana Trujillo, real-time mission control
Of the Colombians participating in key positions in the NASA mission, the most well known is engineer Diana Trujillo. The Cali native, who gained wide recognition in 2020 when she took part in the Mars 2020 Perseverance mission that successfully collected samples from the red planet, holds one of the most demanding roles: flight director.
From the Mission Control Center in Houston, she coordinates real-time operations, integrates data from multiple systems, and makes decisions under pressure during every phase of the flight.
An aerospace engineer, she participated in the Perseverance rover mission on Mars and has established herself as one of the most visible figures at NASA of Colombian origin. She arrived in the United States as a teenager and, while learning English, worked in entry-level jobs before entering the field of engineering.
In Artemis II, her responsibility is total. If an anomaly occurs, she and her team must respond within seconds. In operational terms, her role is one of the final decision-making instances to ensure the crew’s safety.
Liliana Villarreal, the challenge of bringing them back
Liliana Villarreal leads one of the most delicate phases of the mission: the return. As landing and recovery director, she heads the team that coordinates the splashdown of the Orion capsule in the Pacific Ocean and the extraction of the astronauts.
Born in Cartagena, she arrived in the United States as a child, already showing an interest in space exploration. She joined NASA in 2007 and has built a technical career that now places her at a critical point in the mission: the crew’s safe return.
With more than 15 years of experience in space operations, her work involves designing protocols, executing simulations, and coordinating maritime and rescue teams.
In a mission of this kind, success is not measured only by reaching the Moon, but by returning safely. That responsibility rests largely on the team led by Villarreal.
Ivan Ramirez, the precision behind the launch
Ivan Ramirez works at the heart of the launch: the propulsion of the Space Launch System rocket. As a mechanical engineer and analyst at Boeing, he evaluates the behavior of the systems that will propel the Orion spacecraft out of Earth’s orbit.
His work involves modeling scenarios, analyzing fuel performance, and anticipating potential failures. In an environment where any error can compromise the entire mission, his role is essential to ensuring that the launch occurs within expected parameters.
Trained at the National University of Colombia, his profile represents engineers who, without being in the public spotlight, sustain the technical viability of space missions.
In his role as an analyst at Boeing, a key company within the Artemis program, he is responsible for evaluating the behavior of fuels and rocket engines.
Ramirez acknowledges that he once considered becoming an astronaut, but ultimately redirected his passion for space toward technical roles that make these flights possible.
Juan Felipe Garcia, innovation from a new generation
Juan Felipe Garcia is the youngest of the group and represents a new generation of Colombian engineers linked to the aerospace industry. Born in Bucaramanga and a graduate of the Universidad Pontificia Bolivariana, he contributes to the development of technological solutions applied to projects associated with Artemis II.
His work focuses on proposals aimed at optimizing rocket components and improving system efficiency. Although his role is not directly within NASA’s structure, he is part of the network of companies and teams that support the Artemis program.
His case reflects how current space exploration depends on a global network of talent, where innovation does not take place in a single location but across multiple development centers.
Artemis II is a test mission, but its impact will be decisive. Every system that works, every maneuver successfully executed, will bring humanity closer to a sustained return to the Moon.
In that process, Diana Trujillo, Liliana Villarreal, Ivan Ramirez, and Juan Felipe Garcia are part of a structure that will make that objective possible. They will not be in the capsule that orbits the Moon, but their work will travel with it.
Their presence in this mission represents an undeniable personal achievement in their professional careers, but it also opens a window to understanding how far Colombian talent can go when it manages to position itself in the arenas where the future of space exploration is being defined.
