Questions & Answers
Q: Who is Eugene Parker and what contribution did he make to the study of solar winds?
Eugene Parker wrote a paper in 1958 proposing the existence of solar winds, which was initially met with skepticism. However, subsequent observations confirmed his theory, revolutionizing our understanding of the Sun's influence on the solar system.
Q: How was the Parker Solar Probe designed to withstand the extreme conditions near the Sun?
The spacecraft features a carbon-carbon foam sun shield to protect it from high temperatures, reaching up to 1,300 degrees Celsius. Radiators and specialized solar panels were also developed to dissipate heat and power the spacecraft in close proximity to the Sun.
Q: What is the purpose of the Faraday cup on board the Parker Solar Probe?
The Faraday cup is a vital scientific instrument used to measure the density and composition of solar wind particles. It helps scientists understand the Sun's composition and processes, including neutrinos and coronal mass ejections.
Q: What makes the Parker Solar Probe the fastest man-made object in history?
The probe's impressive speed is achieved by being launched on a Delta IV Heavy rocket, one of the most powerful rockets ever built. Its trajectory will utilize gravitational assists from Venus to achieve unparalleled speeds.
