A satellite named after a faiy provided the initial velocity. What followed was a trajectory that carried Philippine space development beyond experimentation and into permanence.
Ten years ago, on April 27 at 8:44 p.m. Philippine time, a compact, 50-kilogram microsatellite no larger than a balikbayan box was released into orbit from the Japanese Kibo module of the International Space Station. That satellite, Diwata-1, marked the country’s formal entry into the space age as a builder of its own spacecraft.
Named after the mythological diwata, a guardian spirit of nature, the satellite was designed to observe the Philippine archipelago from 400 kilometers above Earth. Its mission addressed long-standing gaps in access to timely, high-resolution data for agriculture, forestry, disaster response, and coastal monitoring. For decades, the country had relied heavily on foreign satellite imagery, often constrained by cost, access, and latency. Diwata-1 signaled a shift toward sovereign capability.
The Magnificent 9
The program began in 2014 under the Department of Science and Technology through the Philippine Scientific Earth Observation Microsatellite Program, or PHL-Microsat. Rather than procure a ready-made satellite, the government chose to build local expertise.
Nine Filipino engineers from the DOST Advanced Science and Technology Institute and the University of the Philippines Diliman were trained in Japan at Tohoku University and Hokkaido University. The group, later known as the “Magnificent 9,” led the design, assembly, and testing of the satellite. They developed its core systems and integrated four imaging payloads tailored to Philippine conditions, from crop monitoring to disaster assessment.
The Magnificent 9 included Harold Bryan Paler, John Leur Labrador, Ariston Gonzalez, Julian Marvick Oliveros, Juan Paolo Espiritu, Delburg Mitchao, Benjamin Jonah Magallon, Kaye Kristine Vergel, and Gerwin Guba.
This approach ensured that the outcome was not just a satellite, but a knowledge base. By the time Diwata-1 was ready for deployment, the Philippines had acquired its first generation of satellite engineers.
A two-stage journey to orbit
Diwata-1 reached space in two phases. It was first launched on March 23, 2016 aboard a Cygnus cargo spacecraft on a SpaceX Falcon 9 rocket from Cape Canaveral. It was transported to the International Space Station, where it remained until deployment.
On April 27, 2016, British astronaut Tim Peake operated the Japanese Experiment Module’s robotic arm to release the satellite into orbit. Within hours, signals were received by ground stations, confirming successful deployment.
PoC no more
Originally designed for an 18-month mission, Diwata-1 exceeded expectations and operated for nearly four years. It captured more than 45,000 images before re-entering the atmosphere on April 6, 2020.
Its success validated the practical use of satellite data in a country regularly impacted by typhoons, flooding, and environmental degradation. Government agencies began integrating space-based imagery into disaster response, land use planning, and resource management.
Just as critical was what followed. Diwata-1 was not a one-off experiment.
In October 2018, the Philippines launched Diwata-2 microsatellite, a more advanced successor equipped with improved cameras and deployable solar panels for extended operations. It provided higher-quality imagery and longer mission life, effectively continuing and expanding the capabilities demonstrated by Diwata-1.
Alongside this, the country began developing smaller CubeSats under the “Maya” program, including Maya-1 CubeSat and its successors. These nanosatellites focused on communications experiments, technology demonstration, and training, further deepening local expertise.
Together, Diwata-2 and the Maya series represent the functional continuation of Diwata-1’s legacy: a transition from a single proof-of-concept mission to a layered satellite ecosystem.
PhilSA: The fairy's grandchild
In 2019, the Philippine government enacted Republic Act 11363, establishing the Philippine Space Agency (PhilSA) and formalizing space development as part of national policy.
Current PhilSA Director General Gay Jane Perez, was part of the core scientific leadership behind Diwata-1, contributing not to the satellite’s hardware assembly but to the mission’s purpose and data utilization.
As a faculty member of the University of the Philippines Diliman and a specialist in geodesy and remote sensing, she worked within the PHL-Microsat Program to ensure that the satellite’s imaging capabilities were aligned with real-world applications in the Philippines. Her role focused on translating raw Earth observation data into actionable information for government use, including land cover mapping, environmental monitoring, and disaster assessment.
She was also involved in building the local ground-based capacity to receive, process, and interpret satellite data, helping bridge the gap between engineering output and policy application. This early involvement positioned her as one of the key figures linking Diwata-1’s technical success to its long-term impact on national space development, a continuity that carries into her leadership at the Philippine Space Agency.
Though the satellite is no longer in orbit, the systems, talent, and institutions it helped create continue to expand.
PhilSA is now preparing for larger and more capable platforms such as the Multispectral Unit for Land Assessment (MULA), aimed at delivering higher-resolution imagery and wider coverage.
Nearly a decade after its deployment, Diwata-1’s significance lies not in its lifespan, but in what it enabled. It transformed the Philippines from a passive recipient of satellite data into an active participant in space-based observation.
