Ancient Roman cities are being rediscovered beneath the water. Researchers are using satellite technology and sonar to map submerged roads and buildings in areas like the Venice Lagoon. This innovative approach helps preserve historical sites and provides a clearer picture of how people lived centuries ago. The findings also shed light on past environmental shifts.

The plan aligns with the government’s broader objective of strengthening India’s capabilities in satellite communications, particularly in LEO systems, as reliance on foreign providers raises strategic and security concerns.

Unlike traditional Earth observation systems that rely on either optical or radar imaging, Mission Drishti combines both to deliver clear, real-time insights in any condition — day, night, or bad weather. Here’s why it matters.

Chinese satellite firm MizarVision, sanctioned by the US for allegedly supplying imagery of American military activity during the Iran conflict, has ingeniously turned the sanctions into a recruitment drive. The company posted a job advertisement featuring the US Treasury notice, inviting applicants who thrive under pressure and embrace strength.

Scientists have identified Lake Maracaibo in Venezuela as the planet's top lightning hotspot. New satellite data reveals this tropical region experiences more lightning activity than the Congo Basin. These hotspots form due to specific atmospheric conditions, with warm air, moisture, and wind patterns creating constant storms. Lake Maracaibo's unique geography allows for nighttime storms, a phenomenon sometimes called Catatumbo lightning.

Google is reportedly in talks with SpaceX for a deal to launch orbital data centers into space, aiming to address energy demands of traditional facilities. While Google and SpaceX see potential in this unproven technology, OpenAI's Sam Altman deems it 'ridiculous' for this decade. Google plans prototype satellite launches by 2027.

Elon Musk navigates a complex relationship in China, where his EV ventures are lauded but his SpaceX satellite network raises military concerns. While celebrated as a social media icon, Tesla faces increasing competition from domestic automakers, potentially dimming Musk's influence.

Mexico City is sinking. New satellite technology from NASA is precisely measuring how much the city is sinking each month. This subsidence is caused by groundwater depletion. The problem has been known for a long time. The new data will help scientists understand the issue better and plan for the future. This is a global problem affecting many cities.

Bengaluru-based GalaxEye launched Drishti, India's largest privately developed Earth observation satellite and the world's first OptoSAR satellite. This innovative spacecraft combines optical and radar imaging, enabling it to 'see' through clouds and darkness, offering crucial capabilities for national security and disaster response.

During a Beijing visit, President Trump observed China's military might, signaling a shift in global power. While the US faces munitions shortages and slow production, China's defense industry operates at wartime pace, excelling in drones, AI, and satellite tech. This evolving warfare, particularly concerning Taiwan, highlights a contest for future global dominance.

Operation Sindoor, marking its first anniversary, redefined India's counter-terrorism strategy with precision strikes and indigenous technology. This 88-hour operation signaled a firm resolve to respond to terror, blurring lines between terror groups and state sponsors. It demonstrated a new doctrine, asserting that future attacks would be treated as acts of war, with air power now a normalized, escalatory control tool.

Brazil's Amazon deforestation is at a decade low, yet forest degradation from fires, logging, and drought poses a significant threat, affecting 40% of the region. Experts warn of a tipping point where the forest could emit more carbon than it absorbs. A proposed bill could weaken crucial satellite monitoring, jeopardizing conservation efforts.
