NASA is testing fire behavior on the Moon. This is different from Earth because the Moon has less gravity.

El estudio liderado por Sarah Thiele introduce el Reloj CRASH. Este mide cuánto tiempo pasaría antes de una colisión grave si, de repente, todos los satélites perdieran su capacidad de maniobrar.
En 2018, ese margen era de 121 días. Hoy, debido a las megaconstelaciones (como Starlink), ese tiempo se ha desplomado a solo 2.8 días.
La saturación del espacio es tan alta que el margen de error es casi inexistente. 📉

The US FCC has authorized SpaceX -StarLink to launch another 7,500 second-generation Starlink satellites, bringing its total authorization to 15,000 Gen2 satellites. Satellites will be positioned into new orbital shells at altitudes ranging from 340 km to 485 km and will support space based Internet and direct-to-cell connectivity for new mobile phone services.

After 53 years in orbit, the Soviet-era Kosmos 482 spacecraft made an uncontrolled reentry into Earth’s atmosphere on May 10, 2025, over the Indian Ocean. Originally intended for a Venus mission in 1972, the craft became long-term space debris due to a launch failure.

"Draco mission made for destruction"

"ESA is preparing the Destructive Reentry Assessment Container Object (Draco) mission that will collect unique measurements during an actual reentry and breakup of a satellite from the inside. A capsule especially designed to survive the destruction will transmit the valuable telemetry shortly after."
