Parker
Solar Probe
The Parker Solar Probe is a NASA space probe launched in 2018 with the mission of making observations of the outer corona of the Sun. It will approach to within 9.86 radii(6.9 million km or 4.3 million miles) from the center of the Sun , and by 2025 will travel, at closest approach , as fast as 690,000 km/h or 0.064% the speed of light. It is the fastest object ever built.
“Somewhere, something incredible is waiting to be known.” - Carl Sagan
The Parker Solar Probe is the first spacecraft to
fly into the low solar corona. It will assess
the structureand dynamics of the Sun's coronal
plasma and magnetic field, the energy flow that
heats the solar corona and impels the solar wind,
and the mechanisms that accelerate energetic
particles.
"That's one small step for man, one giant leap for mankind."
- Neil Armstrong
