Pontes is one of the most experienced jet pilots in the Brazilian Air Force (FAB), where he holds the rank of Lieutenant-Colonel and has flown more than 2000 hours in 25 different aircraft.

In June 1998, he was selected by the Brazilian Space Agency to train in the NASA space program after he acquired a space-related background in the Aeronautical Engineering division of the Instituto Tecnológico de Aeronáutica (the Aeronautics Institute of Technology, or "ITA").
He began NASA training in August 1998 and qualified as Space Shuttle Mission Specialist in December 2000.
He attended the Naval Postgraduate School of the US Navy in 1998.

Initially, Pontes' maiden space flight was scheduled to be on a Space Shuttle, where he was to help transport the ExPRESS Pallet, which would have been the International Space Station's first Brazilian-made component, into orbit.
Negotiations between NASA and AEB (the Brazilian Space Agency) fell through due to budgetary concerns.
During the delay, Pontes ran a campaign to pressure the Brazilian government to complete the Express Pallet, and he worked on technical assignments in the Astronaut Office Space Station Operations Branch at NASA.
His flight was postponed indefinitely when AEB confirmed that it could not produce the Express Pallet and its components for NASA.

On September 2, 2005, an agreement between the governments of Brazil and Russia was reached which provided for Pontes to train at Star City, near Moscow, to learn about the Soyuz's operational and life-support systems, and to fly to the International Space Station in March 2006.
 The agreement, which cost about US$20 million was signed by the presidents of the Brazilian and Russian space agencies, Sérgio Gaudenzi and Anatoli Perminov, respectively.

Pontes' flight coincided with celebrations of the 100th anniversary of Brazilian aviation pioneer Alberto Santos-Dumont's successful flight of a fixed-wing airplane in Paris in October 1906.

On March 30, 2006, Pontes became the first Brazilian and the first native Portuguese-speaking person to go into space, where he stayed on the International Space Station for a week.
During his trip, Pontes carried out eight experiments selected by the Brazilian Space Agency.
He landed in Kazakhstan on April 8, 2006, with the crew of Expedition 12.

Following the Soyuz mission, Pontes returned to his technical duties for the International Space Station Program at the Johnson Space Center, working with FIESP/SENAI-SP on the development and fabrication of the Brazilian parts for the ISS.

Pontes entered the reserve of the Brazilian Air Force and awaits a new space mission.
He is also an Invited Researcher at the Institute for Advanced Studies of the University of São Paulo at São Carlos.
He is an ambassador of UNIDO and WorldSkills.
Pontes opened an educational foundation and a tourism agency together with the future Brazilian space tourist Marcos Palhares, who will be traveling to space through the Virgin Galactic.

Pontes announced his intention to visit space a second time back in 2009.
