History-making probe achieves closest-ever approach to the sun
CNNSign up for CNN’s Wonder Theory science newsletter. CNN — The Parker Solar Probe zoomed by the sun on Tuesday during a record-breaking flyby, coming within 3.8 million miles of the solar surface during humanity’s closest approach to a star. Over the past six years of the spacecraft’s seven-year mission, the Parker Solar Probe has collected data to enlighten scientists about some of the sun’s greatest mysteries. “Parker Solar Probe is changing the field of heliophysics,” said Helene Winters, Parker Solar Probe’s project manager from Johns Hopkins University’s Applied Physics Laboratory, in a statement. NASA/Johns Hopkins APL The spacecraft was built to withstand the extremes of the sun and has flown through coronal mass ejections in the past with no impact to the vehicle, said Parker Solar Probe project scientist Nour Rawafi.
