Answer 1

Parker Solar Probe (previously Solar Probe, Solar Probe Plus, or Solar Probe+, abbreviated PSP)[8] is a NASA robotic spacecraft launched in 2018 and currently en route to probe the outer corona of the Sun.[3][9][6] It will approach to within 9.86 solar radii (6.9 million kilometers or 4.3 million miles)[10][11] from the center of the Sun and by 2025 will travel, at closest approach, as fast as 690,000 km/h (430,000 mph), or 0.064% the speed of light.[10][12]
