A tool created by researchers from the University of São Paulo was used by NASA throughout the Artemis II mission, which took 4 astronauts across the Moon between April 1 and 10, 2026. The tools, referred to as actigraph, was used on the wrists of the astronauts all through the mission to watch sleep patterns, exercise ranges, and light-weight publicity, information thought-about important to grasp how the human physique reacts in deep area. This is the primary time that Brazilian technology participates in a crewed flight to the Moon.
Artemis II, carried out by NASA, was the primary crewed mission to the Moon in 53 years, since Apollo 17 in 1972. The Orion capsule carried American astronauts Reid Wiseman, Victor Glover, and Christina Koch, together with Canadian Jeremy Hansen, to a file distance of 406,771 kilometers from Earth, surpassing the earlier Apollo 13 file by 6,600 km. The 4 handed the far aspect of the Moon, photographed craters by no means seen by human eyes stay, and all through this journey, that they had a watch made at a Brazilian public college on their wrists.
The actigraph was developed on the School of Arts, Sciences, and Humanities of USP (EACH), below the coordination of Professor Mario Pedrazzoli, a specialist in chronobiology. The system measures physique motion, mild depth, and spectral composition of sunshine, together with the so-called blue mild, which regulates the sleep-wake cycle. In area, the place there isn’t a pure day and evening, the human physique loses fundamental biological references and sleep turns into some of the vital components for the efficiency and security of astronauts.
How did a watch from USP get to the wrists of NASA astronauts?

The journey started years earlier than the launch.
Professor Pedrazzoli’s analysis group developed the actigraph for research of sleep problems in Brazilian populations.
The system caught NASA’s consideration for its precision in accumulating mild and motion information in managed environments, precisely the kind of monitoring wanted for long-duration missions exterior Earth’s orbit.
The American area company examined the tools and determined to incorporate it in the Artemis II protocol.
The system seems in official NASA photos on the wrists of the 4 astronauts, which EACH-USP highlighted as a historic achievement for the Brazilian public college.
For the establishment, the usage of the system in a mission of this scale demonstrates that Brazilian scientific analysis has the capability to compete and contribute on the highest stage of area exploration.
The collaboration additionally opens doorways for future partnerships between Brazil and worldwide area packages, particularly contemplating that NASA plans to land astronauts on the lunar floor beginning in 2028 with the Artemis III mission.
What the actigraph revealed and why it issues past area?
The information collected throughout the 10-day mission continues to be being analyzed by NASA and the USP workforce.
But steady monitoring of sleep in excessive area environments has direct functions on Earth.
The similar rigor used to guard astronauts can information diagnoses of sleep problems, create protocols for professionals working irregular shifts, similar to docs, pilots, and army personnel, and help in the formulation of public well being insurance policies.
The reentry of the Orion capsule into the Earth’s ambiance on April 10 generated temperatures of two,760°C on the skin, with a 13-minute plunge that minimize off all radio communications.
The 4 astronauts safely landed in the Pacific Ocean, off the coast of California, with the Brazilian technology intact on their wrists.
Commander Reid Wiseman described the mission as “the most special thing that has ever happened in my life.”
The Artemis II mission lined a complete of 1,117,515 kilometers, in two Earth orbits and one lunar flyby, validating programs that will likely be used in the deliberate lunar touchdown for 2028.
And in each kilometer of that, Brazil was present.
