Construction

While in Brazil the São Paulo-Rio high-speed train never materialized, China plans to tunnel 120 km under the sea to connect two cities by rail — 90 km will be underwater, with trains at 250 km/h, and the 8-hour journey will be reduced to 40 minutes.

Armed Forces

The U.S. Army and Navy jointly tested a missile that exceeds Mach 5 and travels at over 6,100 km/h — it maneuvers in the air, evades any radar, and no existing defense system is capable of intercepting it.

Science and Technology

In 2022, NASA shot a spacecraft at an asteroid at 6.6 km per second and changed its orbit by 33 minutes — now Europe’s Hera probe is traveling there to inspect the damage and make planetary defense an exact science.

Two African countries will inaugurate in 4 days an 825-meter bridge suspended 90 meters high over a reservoir — it is the largest of three bridges of a megaproject that will supply millions of people.
