With reference to the Space debris, consider the following statements:...
On May 12, fragments of suspected debris “fell from space” at three locations in Gujarat — Bhalej, Khambholaj, and Rampura.
- Space debris can include natural space debris such as meteoroids, or man-made ones which can include defunct spacecrafts and satellites, stages of rockets which have launched payloads, dead satellites, satellite explosions and collisions.
- According to NASA, “more than 25,000 objects larger than 10 cm are known to exist” as space debris and the estimated population of particles between 1 and 10 cm in diameter is approximately 500,000.
- According to NASA’s estimates, as of January 2022, the amount of material orbiting the Earth exceeded 9,000 metric tons.
The difference in impact made by a natural and man-made debris
- Most pieces of space debris burn up as they enter the Earth’s atmosphere, the process starting from around a height of 100 km from Earth’s surface to 20 km.
- However, sometimes, very heavy pieces may not burn completely, and some part of the object may make it down to the surface, either hitting a landmass or a waterbody.
- In cases of man-made debris, it often disintegrates into fragments, thus hardly ever creating large-scale impact. It is usually natural debris, such as asteroids and meteoroids, that cause relatively large-scale craters, if it ends up hitting a landmass.
Hence both statements are correct.
