Parker Solar Probe ready to touch Sun’s atmosphere in 2018

  • NASA’s solar probe will be launched in summer of 2018.
  • It will make repeated trips through the sun’s outer atmosphere, passing within 4 million miles of the star’s blazing surface.
  • The probe will reach a speed of 450,000 mph around the sun.

This is NASA’s first mission to the sun and its outermost atmosphere, called the corona.

         About Parker Solar Probe.

  • Protected by a 4.5-inch-thick carbon-composite heat shield, the Parker Solar Probe will endure temperatures up to 2,500 degrees Fahrenheit.
  • The 10-feet high Parker Solar Probe will fly within 6.4 million km of the sun’s surface right into the solar atmosphere.
  • Initially the probe was named as Solar Probe Plus which has been renamed as the Parker Solar Probe in honor of astrophysicist Eugene Parker
  • This is first time in History NASA has named a spacecraft from a living person Astrophysicist Eugene Parker.
  • The Probe will be going to be seven times closer than any other mission has ever been till date

    Research of Eugene Parker.

  • In 1958 Parker published research predicting the existence of solar wind, when he was a young professor  at the University of Chicago’s Enrico Fermi institute.
  • first his theory was rejected but later after 2 years with the help of sattelite observation his papaer was published.

    Objective of the mission.

  •  To shed light on what powers the sun’s high-temperature corona, the origins of the solar wind and the causes of potentially catastrophic solar storms.
  • determining the structure and dynamics of the plasma and magnetic fields at the sources of the solar wind.
  • According to the schedule the mission will end in June 2025.
