the Parker Solar Probe spacecraft relies on a carbon foam shield to protect it from the extreme heat in the upper solar atmosphere called the corona, which can exceed 1 million degrees Fahrenheit. The shield was designed to reach temperatures of 2,600 degrees Fahrenheit — hot enough to melt steel — while keeping the instruments behind it shaded at a comfortable room temperature. In the hot but low-density corona, the spacecraft’s shield is expected to warm to 1,800 degrees Fahrenheit. By flying through the solar corona, Parker Solar Probe can take measurements that help scientists better understand how the region gets so hot, trace the origin of the solar wind (a constant flow of material escaping the Sun), and discover how energetic particles are accelerated to half the speed of light. By getting firsthand accounts of what’s happening in the solar atmosphere, the Parker Solar Probe has revolutionized our understanding of the Sun. The eerie sounding solar winds you’re hearing in this video, are a stream of charged particles released from the Sun's outermost atmospheric layer, the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic energy. #space #universe #astronomy #astronomytok #astro #spacetok #fyp #sun #thesun #corona #solar #solarstorm #solarflare #solarenergy #parker #parkerprobe #parkersolarprobe #probe #atmosphere #wind #soundon #deepspace #outerspace - @explainspace
