026, the Argentine microsatellite ATENEA made history by transmitting data from approximately 70,000 kilometers away, the farthest distance reached by any Argentine space mission. This milestone occurred shortly after its release during the Artemis II mission, which aims to return humans to lunar orbit for the first time in over fifty years.

Developed collaboratively by Argentine public institutions and a private company, ATENEA's success highlights the country's advancements in space technology. It established communication with ground stations in both Córdoba and Tierra del Fuego just hours after being launched, confirming the robustness of Argentina's space capabilities.

The satellite's main objectives include testing and validating technologies related to space radiation, GPS data, and long-range communication links, with implications for future deep-space exploration programs. Despite limited resources, the development of this 12U CubeSat demonstrates the potential of Argentina's scientific community, bringing together contributions from several national universities and research institutions.

ATENEA was one of four satellites released during the Artemis II mission, alongside systems from Germany, Saudi Arabia, and South Korea; however, the latter two did not successfully establish communications.

The successful operation of ATENEA not only represents a national achievement but also paves the way for more ambitious missions, reinforcing Argentina's commitment to space exploration and innovation.
