NASA'S PARKER SOLAR PROBE MISSION PARKER SOLAR PROBE MISSION • The Parker Solar Sample of NASA began in August 2018, and soon was the nearest starship to the Sun. • Parker Solar Probe has ended three of 24 proposed passes through never studied areas of Sun's atmosphere, the corona, by using sophisticated science instruments to measure the environment surrounding the spacecraft.

Our star is magnetically active, releasing intense light blasts, particle dumps travelling near light speed and billiards of tonnes of magnetised material clouds.

Source: www.sciencedaily.com THE DYNAMIC SOLAR WIND • The solar wind is a relatively uniform, often tumbling plasma wave near the Earth. • At that point, however, it has travelled over ninety million kilometres and Sun's exact heating and accelerating processes are eliminated. Source: www.newsheads.com PLASMA • As in the solar wind itself, plasma is the best way to build a sea of free-floating particles with a single electric charge. Negative charged electrons are often distinguished from positively charged ions. • This floating free particles mean that plasma holds electric and magnetic fields and plasma modifications are also distinguished by those fields. Source: www.spaceconnect.com ELECTRIC AND MAGNETIC FIELDS • The FIELDS instruments analysed the state of the solar wind through observations and careful study, along with measuring waves in the surrounding plasma, of how electric and magnetic fields around the vessel have moved. Source: www.sciencedaily.com THE ROTATING SOLAR WIND • We see almost radially the solar wind, near the surface, which means it streams straight from the Sun in any way. • But the Sun flips as it releases the solar wind, and the solar wind spins with it until it breaks loose.
