In a historic announcement that bridges the legacy of
military service with the next phase of human space exploration, NASA
announced that Army Col. Frank Rubio, assigned to the U.S. Army Space
and Missile Defense Command, will serve as a mission specialist on its
upcoming Artemis III mission. The announcement, made yesterday at the
Johnson Space Center in Houston, places a soldier at the forefront of
humanity's return to the lunar surface.
Rubio will join NASA astronauts Randy Bresnik and Andre Douglas, as
well as European Space Agency astronaut Luca Parmitano, as they embark
on a mission that will serve as a low-Earth orbit demonstration to test
systems required for operations in the region between Earth and the
moon's orbit.
Rubio's selection is a testament to his recognized leadership, broad
career experience and the technical expertise that soldiers bring to the
nation's human spaceflight program.
"I am deeply honored to be selected for Artemis III, a mission that
continues to build upon the foundation for the day Americans return to
the surface of the moon," Rubio said. "My Army training has been an
integral part of the experiences that have enabled me to be ready for
this mission. Serving taught me to lead under pressure, how to stay calm
when the stakes are highest, and how to put the mission and the people
beside you above yourself."
"To those who have served, and to every soldier and military family
serving right now: you are the backbone of everything we do as a nation,
including this," he continued. "I am honored to represent the Army on
the highest ground."
Rubio is no stranger to making history in orbit. He holds the
American record for the longest single spaceflight, having spent 371
consecutive days aboard the International Space Station during
Expeditions 68 and 69 from September 2022 to September 2023.
During that unexpectedly extended spaceflight, Rubio completed 5,963
orbits of the Earth, traveled more than 157 million miles and conducted
three spacewalks totaling 21 hours and 24 minutes. This extensive
previous spaceflight experience, marked by deep resilience and
adaptability, makes him uniquely qualified to serve under the demanding
conditions that will be expected of him and the other Artemis III
crewmembers.
Before his selection by NASA in 2017 as a member of Astronaut Class
22, Rubio built a distinguished 19-year military career as both an Army
aviator and physician. A 1998 graduate of the U.S. Military Academy at
West Point, New York, where he was a member of the Black Knights
parachute team, Rubio served as a UH-60 Black Hawk helicopter pilot. He
flew more than 1,100 hours, including more than 600 hours of combat and
imminent danger time during deployments to Bosnia, Afghanistan and Iraq.
Following his service in the aviation branch, Rubio earned his
medical degree from the Uniformed Services University of the Health
Sciences in 2010. As a board-certified family physician and flight
surgeon, he completed his residency at Fort Benning, Georgia, and
subsequently served as a clinic supervisor at Redstone Arsenal, Alabama.
Rubio was stationed as a battalion surgeon assigned to the 3rd
Battalion, 10th Special Forces Group at Fort Carson, Colorado, at the
time of his astronaut selection.
Rubio's selection highlights the critical contributions of the U.S.
Army Space and Missile Defense Command NASA Detachment, located at the
Johnson Space Center. The detachment bolsters NASA's human spaceflight
program by providing active-duty soldiers and space operations officers
who deliver leadership, technical expertise and risk management skills.
Alongside Rubio, the detachment currently includes Army Col. Anne
McClain, a veteran astronaut and detachment commander; Army Chief
Warrant Officer 3 Joseph Bailey, who in 2025 became the first Army
warrant officer selected as an astronaut candidate; and two Army space
operations officers and administrative personnel.
Since 1978, a select group of 20 Army astronauts and payload
specialists have served at NASA. These Army astronauts and space
operations officers not only provide vital human-machine interface and
engineering expertise to NASA's operations, but they also bring back
invaluable experience and information from NASA and aerospace industry
partners to the Army.
"Congratulations to Col. Frank Rubio on his selection for the Artemis
III mission," said Army Lt. Gen. John Rafferty, commanding general of
U.S. Army Space and Missile Defense Command. "His selection is a
testament to his leadership, physical and mental toughness, and
technical capability. The U.S. Army celebrates this milestone, and we at
U.S. Army Space and Missile Defense Command are incredibly proud of him
and the Army astronaut program."
According to NASA, Artemis III's primary objectives for its mid-2027
flight are to test and validate commercial human landing systems. The
mission will focus on critical docking operations between the Orion
spacecraft and these landing systems. It will also be an opportunity for
NASA to conduct the first operational tests of new space suits in
orbit.
NASA officials further stated Artemis III's flight will provide the
flight experience and standardized vehicle configurations necessary to
support subsequent operations. Data gathered from the orbit
demonstration will directly clear the path for future crewed landings on
the moon and eventual human missions to Mars.
