Particle
In space and astronautical engineering, a particle refers to a small object or substance that exists in space, such as dust, gas, or plasma. Particles can have a significant impact on spacecraft and their instruments, as they can cause damage or interfere with measurements. For example, micrometeoroids, which are small particles of rock or metal, can cause damage to spacecraft and satellites. Additionally, charged particles in space, such as those found in the Van Allen radiation belts, can interfere with electronics and cause radiation damage to astronauts. Understanding the behavior and effects of particles in space is important for designing and operating spacecraft and for protecting astronauts from harmful radiation.
