            "description": "The corona is the sun’s outer atmosphere and a constant source of curiosity for scientists who study our star. The corona is hundreds of times hotter than the sun’s surface. This is contrary to our normal experience - that it's cooler further away from a source of heat - so it poses a mystery for solar scientists. The corona is also where magnetic, energetic solar material is accelerated out into space in a non-stop flow called the solar wind. Launching in 2018, Parker Solar Probe will fly through the corona, closer to the sun’s surface than any other spacecraft to date. Scientists hope this data will help them understand how heat and energy move through the corona and drive the solar wind, which can cause space weather here on Earth. Parker Solar Probe will make two dozen close approaches to the sun over its seven-year mission. NASA named this mission in honor of Eugene Parker, a solar astrophysicist who revolutionized our understanding of how the sun’s emissions affect our solar system. Watch the video to learn more.",

            "description": "NASA’s Parker Solar Probe passed laser illumination testing the week of Nov. 27, 2017. During this test, each segment of the spacecraft’s solar panels was illuminated with lasers to check that they were still electrically connected after the vigorous vibration and acoustic testing completed earlier this fall. NASA’s Parker Solar Probe is in the midst of intense environmental testing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in preparation for its journey to the Sun. These tests have simulated the noise and shaking the spacecraft will experience during its launch from Cape Canaveral, Florida, scheduled for July 31, 2018.Parker Solar Probe’s integration and testing team must check over the spacecraft and systems to make sure everything is still in optimal working condition after experiencing these rigorous conditions – including a check of the solar arrays, which will provide electrical power to the spacecraft.Parker Solar Probe will explore the Sun's outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also help improve how we forecast major eruptions on the Sun and subsequent space weather events that can impact life on Earth, as well as satellites and astronauts in space. The mission is named for Eugene N. Parker, whose profound insights into solar physics and processes have helped shape the field of heliophysics.Link to Parker Solar Probe blog post. || ",

            "description": "A massive spray of high-energy particles blasted from the sun and shot into space during a magnificent solar eruption captured by NASA's Solar Dynamics Observatory (SDO) satellite. The spectacular event took place on June 7, 2011 over a period of six hours when an M-2 class (medium-sized) solar flare, a large prominence eruption, and a coronal mass ejection were observed from sunspot complex 1226-1227. Scientists estimate hot plasma and powerful X-rays burst into the sun's atmosphere and exited the corona at speeds over 3 million mph. Trapped particles unable to reach escape velocity traversed the solar sky in evanescent arcs, some traveling more than 215,000 miles, and showered the surface in a speckled array of bright flashes as the fiery sphere reheated the slightly cooled material. The Atmospheric Imaging Assembly instrument on SDO recorded the event at multiple wavelengths using its extreme UV sensor and transmitted the images to Earth in awesome 16.8 mega-pixel resolution. Watch a time-lapse video of the eruption below and relive the moment. || ",
