Mars may rely on asteroids to come off the drawing board: scientists propose seeking metals in space, using other bodies as fuel stations, and facing journeys so slow that a Martian base would take generations to be built far from the current Earth.

Science and Technology

Building-sized asteroids can hit Earth every two decades, say MIT scientists; they rarely cause direct casualties, but the impact can damage satellites and shut down GPS, weather forecasting, and communications in a chain reaction.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

Scientists have created a material six times lighter than air, 75 times lighter than styrofoam, and that becomes stronger the more it is compressed: aerographite seems impossible, but it can reinforce structures, batteries, and satellites.

Described by astronauts as one of the most unlikely natural phenomena on Earth, the Okavango Delta spreads over up to 15,000 square kilometers in the middle of the desert and transforms Botswana into a living labyrinth of channels, islands, and flooded areas.
