On August 12, NASA’s Parker Solar Probe completed a year in service.

 

Background

  • It is part of NASA’s “Living with a Star” programme that explores different aspects of the Sun-Earth system.
  • The probe seeks to gather information about the Sun’s atmosphere and NASA aims to revolutionize our understanding of the Sun. It is also the closest a human-made object has ever gone to the Sun.

Details

  • Parker Solar Probe (previously Solar Probe, Solar Probe Plus, or Solar Probe+, abbreviated PSP) is a NASA robotic spacecraft launched in 2018, with the mission of repeatedly probing and making observations of the outer corona of the Sun.
  • The mission’s central aim is to trace how energy and heat move through the Sun’s corona and to study the source of the solar wind’s acceleration. The mission is likely to last for seven years during which it will complete 24 orbits.
  • Other goals of the mission are
  • Determine the structure and dynamics of the magnetic fields at the sources of solar wind.
  • Determine what mechanisms accelerate and transport energetic particles.
