Parker Solar Probe: NASA

The Parker Solar Probe, launched by NASA, has become the first spacecraft to fly through the outer atmosphere of the Sun- ‘Corona’.

  • The spacecraft flew through Corona and sampled magnetic fields and particles there.
  • The achievement would help scientists discover critical information about the sun and its influence on our solar system.
  • Launched in 2018, Parker Solar Probe will travel through the sun’s atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions — and ultimately providing humanity with the closest-ever observations of a star.
  • In order to unlock the mysteries of the sun’s atmosphere, Parker Solar Probe will use Venus’ gravity during seven flybys over nearly seven years to gradually bring its orbit closer to the sun.
  • The spacecraft will fly through the sun’s atmosphere as close as 3.9 million miles to our star’s surface, well within the orbit of Mercury and more than seven times closer than any spacecraft has come before.

Parker Solar Probe has three detailed science objectives:

  • Trace the flow of energy that heats and accelerates the solar corona and solar wind.
  • Determine the structure and dynamics of the plasma and magnetic fields at the sources of the solar wind.
  • Explore mechanisms that accelerate and transport energetic particles.
