[3] In 1965 two Gamma Centauro sounding rockets developed by the Argentine Air Force and two high altitude balloons carrying instruments for x-ray measurements where launched from the base, under collaboration with the University of Tucumán and the Instituto de Investigaciones Aeronáuticas y Espaciales.

Amidst very bad weather, the aircraft crashed without casualties and the evacuation had to be delayed until the icebreaker ARA General San Martín could finally take over and succeed with the mission.

As of 2008[update] Matienzo is composed of 6 buildings and includes facilities such as: main and emergency houses, airstrip, helipad, fuel platform, central power station with two Antarctic gas oil generators, waste treatment plant, laboratory, freezing chamber, a warehouse and several deposits.

[3] The base actively manages preservation and restoration of the surrounding environment; garbage and waste is removed, concentrated, classified, packaged and compacted for later disposal in the Argentine mainland.

[3] Scientists at Matienzo carry out meteorological, ionospheric, oceanographic and snow science observations; they perform aerial photographic surveys and studies on geology and geophysics involving high precision gravity and magnetism measurements.

[3] Retreat and collapse of the Larsen Ice Shelf is constantly monitored by analyzing satellite imagery, GPS positioning and terrain data to investigate the ice-climate interactions in critical areas under climate change conditions.
