How do you catch a 120-meter skyscraper falling back from space?
Controlling SpaceX's massive Starship stack as it plunges back through the atmosphere requires a masterclass in physics and autonomous engineering. As the Super Heavy booster returns from space at hypersonic speeds, grid fins steer its descent while a high-velocity "boostback burn" reverses its momentum. Inches above the launch pad, Raptor engines reignite for a pinpoint landing burn, allowing giant mechanical tower arms—affectionately dubbed "Mechazilla"—to literally catch the multi-ton rocket out of mid-air.

Years of criticism from Argentina's fans and media couldn't break Messi.
A recycled propaganda campaign calling him a "zionist" over a peace tour that visited both Israel and Palestine won't either.
