** Initial results from Parker Solar Probe<\/a> published<\/strong>: First NASA Parker Solar Probe Results Reveal Surprising Details of Sun – NASA<\/a><\/p>\n

The information Parker has uncovered about how the Sun constantly ejects material and energy will help scientists rewrite the models they use to understand and predict the space weather around our planet, and understand the process by which stars are created and evolve. This information will be vital to protecting astronauts and technology in space \u2013 an important part of NASA\u2019s Artemis program<\/a>, which will send the first woman and the next man to the Moon by 2024 and, eventually, on to Mars.<\/em><\/p>\n

The four papers, now available online<\/a> from the journal Nature, describe Parker\u2019s unprecedented near-Sun observations through two record-breaking close flybys. They reveal new insights into the processes that drive the solar wind \u2013 the constant outflow of hot, ionized gas that streams outward from the Sun and fills up the solar system \u2013 and how the solar wind couples with solar rotation. Through these flybys, the mission also has examined the dust of the coronal environment, and spotted particle acceleration events so small that they are undetectable from Earth, which is nearly 93 million miles from the Sun.\u00a0\u00a0<\/em><\/p>\n

During its initial flybys, Parker studied the Sun from a distance of about 15 million miles. That is already closer to the Sun than Mercury, but the spacecraft will get even closer in the future, as it travels at more than 213,000 mph, faster than any previous spacecraft.<\/em><\/p>\n
