University of Chile's SUCHAI-4 Satellite Reached Space Carrying 60 Experiments

Chile's newest achievement in the field of space sciences came with the successful launch of the SUCHAI-4 nanosatellite, developed by the Space and Planetary Exploration Laboratory (SPEL) of the Faculty of Physical and Mathematical Sciences (FCFM) at the University of Chile. This historic event, which took place in the morning hours local time, is considered a major turning point for the country's aviation and aerospace engineering vision. The device, featuring a 3-unit (3U) CubeSat design, took off from Vandenberg Space Force Base in California, USA. The launch was successfully carried out as part of SpaceX's Transporter-17 mission, accompanied by international partnerships including the Italian company D-Orbit. Thus, SUCHAI-4 was placed into a Sun-synchronous polar orbit at an altitude of approximately 590 kilometers, setting off into the depths of space to begin its duties.

Professor Marcos Díaz, the project's lead researcher and FCFM academic, detailed the technological leap brought by this unique mission and the upcoming challenges following the satellite's launch. Díaz stated that successfully integrating a wide variety of scientific instruments into this small-sized satellite was a source of pride in itself for the teams. This advanced technology infrastructure allows the satellite to operate with an unprecedented level of autonomy and precision. SUCHAI-4 essentially functions as a combined and intensified version of previous SUCHAI-2, SUCHAI-3, and PlantSat models on a single platform. Emphasizing that the most critical current stage is waiting for the first signals from the satellite alongside radio amateurs and Chilean students from all over the world, Díaz expressed their eagerness for SUCHAI-4 to become fully active and start being commanded.

Weighing only five kilograms and having a volume of five liters, SUCHAI-4 will operate like a fully equipped and completely autonomous laboratory in orbit thanks to its technical hardware. Its biggest difference from previous Chilean satellites is that it has a high-precision, state-of-the-art control system for space navigation and stabilization (stepping) operations. Thanks to this advanced control system, the satellite will have the opportunity to test next-generation laser-based optical communication systems towards Earth. Additionally, it will evaluate the performance of LoRa (Long Range) radio systems to collect and transmit data from remote regions. Carrying a special telescope covering ultraviolet and near-infrared spectra for scientific observations, the device will also host experiments to study how biological samples react to the space environment.

FCFM Dean Susana Mondschein also emphasized the great importance of sending SUCHAI-4 into space for Chile's domestic engineering and higher education system. Mondschein stated that this successful operation is a profound source of pride for the faculty and has renewed confidence in the country's space sciences ecosystem. She added that such high-tech missions are not only the fruit of years of academic research and technological development in laboratories but also offer an invaluable practical training platform for students. The dean underlined that the University of Chile has proven to the entire world that it has the capacity to undertake highly complex and ambitious space missions firsthand in terms of human resources, infrastructure, and technical equipment.

The realization of the SUCHAI-4 project depended on the creation of a broad network of financial support and institutional collaborations. Developed thanks to funds provided by the National Research and Development Agency (ANID) through its Fondef, Fondecyt, and Anillo programs, this study constitutes one of the finest examples of scientific solidarity in the country. Prominent national institutions such as the Undersecretariat of Telecommunications (SUBTEL), University of Santiago de Chile (USACH), Pontifical Catholic University of Valparaíso (PUCV), University of Antofagasta, and the Chilean Nuclear Energy Commission (CCHEN) actively participated in the project. Furthermore, the project found a global collaboration ground through experts from international institutions in the USA, Canada, and the Netherlands. Following its successful launch and placement into orbit, SUCHAI-4 has officially started its duties, which will attract the attention of the whole world, to conduct approximately 60 different scientific and technological experiments in space after completing its preparations.
