O satélite espião usará um sistema de lidar de abertura sintética (SAL), que emite pulsos de luz e capta os reflexos para criar imagens detalhadas. Essa tecnologia permite identificar rostos e objetos com precisão milimétrica a mais de 100 km de distância, operando dia e noite, mesmo em condições climáticas adversas.

Scientists in Beijing created a spy satellite with laser camera technology capable of identifying faces from more than 100 km away. The system, tested in Qinghai Lake, uses synthetic aperture lidar (SAL) to capture high-resolution images, even at night and under adverse weather conditions. This innovation raises global concerns about security and privacy.

China has developed a spy satellite with an advanced camera that can identify faces from more than 100 km above the surface. The technology, created in Beijing, uses an innovative laser system and can be installed on military satellites or the Tiangong Space Station, which orbits Earth at about 450 km altitude.

How Does This Spy Satellite Work?

The camera, which will be placed on the satellite, uses synthetic aperture lidar (SAL), a remote sensing system that emits light pulses and measures the reflected energy. This allows for detailed 2D and 3D images to be created, even at night or in adverse weather conditions.

In the first test, conducted at Qinghai Lake in northwest China, scientists managed to capture high-resolution images at a distance of 101.8 km. The system identified minute details, such as objects 1.7 mm in size.

What Concerns Specialists?

The new technology could be a breakthrough in global espionage. Robert Morton, from the Association of Former Intelligence Officers (AFIO), labeled the discovery as a “huge security concern.”

China already operates around 300 surveillance satellites in low orbits. In December 2023, the country launched Yaogan-41, capable of tracking vehicles across the Indo-Pacific region.

Julia Aymonier, a technology expert, commented on LinkedIn:
“The future of space surveillance has arrived, and it is more powerful than we imagined.”

When Will This Technology Be Launched?

There is still no official date for the launch, but project details were published in the Chinese Journal of Lasers. The Chinese government also faces criticism for using spy balloons, facial recognition cameras, and even a social scoring system that tracks citizens.

If the spy satellite becomes operational, China could elevate surveillance to a new level. The world is watching this advancement and its potential implications for global privacy.

When Will This Technology Be Launched?

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

SpaceX will dock a $843 million vehicle to the International Space Station to push a nearly 420-ton laboratory against the atmosphere and make the debris fall in a controlled manner into the ocean.

Scientists considered detonating 213 nuclear bombs in the Sahara to create an artificial sea the size of El Salvador, with each explosion being a hundred times more powerful than the Hiroshima bomb, and the goal was to generate more energy than Egypt’s largest hydroelectric plant.

As the Trump name returns to the high-end real estate market, Ivanka Trump announces the Sazan project; Mediterranean island set to feature hotels, beaches, leisure, and exclusive residences.

Unemployed and with a child to support, Joab turned hot coffee into a fresh start: he wakes up at 2 a.m., sells on Anhanguera, lets drivers pay later through the “trust Pix,” and conquers the internet even when some continue their journey without depositing.

The explosion in Siberia, recorded on June 30, 1908, over Tunguska, released energy estimated between 10 and 15 megatons of TNT, devastated about 2,150 square kilometers of forest, knocked down approximately 80 million trees, and remains one of the biggest warnings about near-Earth objects.

Lock manufacturer from Rio Grande do Sul invests R$ 150 million to surpass R$ 1 billion in revenue, create 200 jobs, and double storage capacity, while choosing Santa Catarina to set up a new logistics center and speed up deliveries in Southern Brazil.
