The Parker Solar Probe has yielded considerable insight into the formation and structure of solar winds, providing scientists that hopefully will help them better predict when mammoth ejections of solar material will occur. Coronal mass ejections can disable communications and defense satellites and can harm astronauts outside of Earth’s protective electromagnetic field.
Launched in August 2018, the probe has passed closer to the sun than at any previous spacecraft in history. The vessel is equipped with a suite of high-tech instruments engineered to withstand the sun’s blistering heat — it will pass within 15 million miles of the sun, compared to the 36 million miles of Mercury’s orbit. Instruments include five antennas, an image maker, and devices that measure the energies of different particles.
The mission’s goal is to “understand the sources and structure of the solar wind up close right as it leaves the sun,” said physicist Stuart Bale of the University of California-Berkeley, in the press conference reported by Popular Mechanics. “What Parker has done has got us closer than ever to the Sun and now we can really see a lot of structure and we can see in this case we can clearly see a source of the wind.”
