The US National Aeronautics and Space Administration (NASA) is sending an exploration vehicle to the Sun at the beginning of August, in the hope of solving the star’s mysteries. In a statement, NASA announced that the car-sized vehicle called “Parker Solar Probe” will be launched on a Delta 4 rocket after August 6. The Parker Solar Probe is scheduled to circle the Sun 24 times in the star’s million-degree atmosphere, called the “corona”. It was stated that the exploration vehicle will study the Sun more closely than any man-made vehicle so far. Among the tasks of the vehicle are to try to decode the mysteries of the solar wind acceleration, the constant outflow of matter from the star, and the extreme high temperature in the corona. The explorer is also expected to help understand the mechanism behind the acceleration of the Sun's active particles. The Sun's active particles reach more than half the speed of light as they hurtle away from the star. Scientists suggest that the vehicle’s heat-resistant shield will make this mission possible.
