Parker Solar Probe

  • It is NASA’s mission to explore Sun’s outer atmosphere.
  • Aims:
    • To trace how energy and heat move through solar corona.
    • To explore what accelerates solar wind as well as solar energetic particles.
    • Determine structure and dynamics of magnetic fields at sources of solar wind.
    • Explore dusty plasma near Sun and its influence on solar wind and energetic particle formation.
  • It is a robotic spacecraft.
  • It is named after solar astrophysicist Eugene Parker, first spacecraft of NASA to be named after living person.
  • Launched in 2018.
  • In its seven-year mission, PSP will explore Sun’s outer atmosphere and make critical observations to answer questions about physics of stars.
  • Its data will also be useful in improving forecasts of major eruptions on Sun and subsequent space weather events that impact technology on Earth, as well as satellites and astronauts in space.
