Exploring the Sun closer than ever before
The Parker Solar Probe (PSP) is an exciting mission of exploration and discovery, the closest a spacecraft has approached the Sun itself. By flying into the Sun’s outer atmosphere—called the corona—the Parker Solar Probe will gather data on the processes that heat the corona and accelerate the solar wind—solving two fundamental mysteries that have been top-priority science goals for many decades. This mission will transform our understanding of the Sun and Sun-like stars, enabling further exploration through our own solar system. It is also taking never before seen views of Venus.
