As I was starting university, the first Venezuelan-owned satellite was launched. I remember a professor commenting in the middle of a class, packed with students, that the satellite about to be launched would only serve to spy on us and that, beyond being an unnecessary expense, it wouldn't bring the progress they were so loudly proclaiming. I turned to look at my classmates, my eyes wide, and wondered how anyone could even think such a thing aloud. Professor Martínez was as far from the truth as the distance between our satellite in space and Caracas.
This device not only allows us to communicate more effectively, as has happened over the years, but also helps preserve our natural heritage and watersheds in the contemporary era. Thanks to it, traditional field patrols have been transcended to integrate with cutting-edge orbital technology. The strategic and ongoing role of the VRSS-2 satellite, named the Antonio José de Sucre Satellite, is highlighted by the Bolivarian Agency for Space Activities (ABAE), as the main technological resource for monitoring, precision mapping, and protecting the national parks of Venezuelan territory.
Years passed since the first satellite and in October 2017 the second Earth observation satellite was put into orbit; the device offers technical capabilities aimed at the detailed monitoring of vegetation cover, the control of land use change and the geotechnical assessment of risks.
The technology behind the lens: Remote and infrared sensors
At an approximate altitude of 650 kilometers in sun-synchronous orbit (which translates to a trajectory at the same solar time every day), the instrumental architecture of the Sucre Satellite incorporates high-resolution cameras and multispectral sensors capable of capturing radiation at wavelengths not visible to the human eye.
How does this apply to conservation biology and environmental bioengineering? To understand this, we will divide it into three key fundamental aspects:
Near-infrared (NIR) spectrum: This band is essential for calculating the Normalized Difference Vegetation Index (NDVI). By measuring chlorophyll reflectance, researchers can assess forest canopy health, identify areas under severe water stress, or monitor variations in biomass in tropical rainforests and cloud forests.
Early warning thermal camera: Capable of recording temperature variations on the Earth's surface, it functions as a thermal anomaly detector. This allows for the georeferencing of heat sources and helps prevent the spread of forest fires in parks with complex geography such as Waraira Repano, Canaima, or Henri Pittier.
Combined spatial resolution: The panchromatic sensor offers a resolution of up to 1 meter per pixel, while the multispectral channel reaches 4 meters. This sharpness allows for the creation of high-definition maps to detect unauthorized human interventions, such as indiscriminate logging or the establishment of mining activities in protected areas.
This flow of geomatic information generated by the Sucre satellite constitutes a direct technical input for the conservation work carried out by the Ministry of Ecosocialism (Minec) and the National Parks Institute (Inparques).
How do these institutions work with this information?
Monitoring deforestation and illegal logging: By comparing time series of satellite images, ABAE analysts identify losses in forest cover density in priority river margins and watersheds.
Assessment of socio-natural disasters: In events of landslides, floods or large-scale fires, the VRSS-2 captures offer an expedited diagnosis of the extent of the damage, guiding the work of reforestation, mitigation and restoration of ecosystems.
Delimitation of preservation areas, facilitating land management by accurately and scientifically defining the boundaries of core areas, buffer zones and biological corridors of the national park network.
The reception, processing and distribution of images processed from the Apure Satellite Control Ground Station and the Main Control Center in Guárico reaffirms Venezuelan space sovereignty.
This technological independence ensures that strategic data on our natural resources is managed locally by 100% Venezuelan talent. This not only expedites the immediate response to environmental emergencies and consolidates the use of space science for the benefit of ecosystem sustainability—which translates into environmental conservation not only for the country but for the world—but also revalues the efforts of our scientists and engineers who continue to choose to live and grow within their country; like Professor Martínez, who, beyond her focus on technology and her initial purpose, believed in the country and helped train men and women who continue to make Venezuela proud.
Excellent information!
