It will fly within 4 million miles of the sun's surface — seven times closer than any spacecraft has gotten before. Members of the integration and testing team roll Parker Solar Probe into the acoustic test chamber at Goddard. The Parker Solar Probe descends into the thermal vacuum chamber at NASA's Goddard Space Flight Center. Additionally, the solar probe's heat shield can withstand temperatures up to 2,600 F degrees, not 3,000.
