PARKER SOLAR PROBE

Aug. 19, 2019

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

About: 

  • Parker Solar Probe 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.

  • One of Parker's main objectives is to investigate what mechanism might be driving extreme heating in the sun's outermost layer, known as the corona.

  • Scientists are curious as why the corona is over a million degrees Fahrenheit (over 555,000 degrees Celsius), while the solar layers below are only a few thousand degrees Fahrenheit each.

  • It is the closest a human-made object has ever gone to the Sun.

  • The mission is likely to last for seven years during which it will complete 24 orbits.
