- NASA’s pioneering Parker Solar Probe made history, when it flew closer to the sun than any other spacecraft, with its heat shield exposed to scorching temperatures topping 930 degrees Celsius
- Launch Vehicle - Delta IV-Heavy with Upper Stage
- Launched in August 2018, the spaceship is on a seven-year mission
- Became the first spacecraft to fly through the corona – the Sun’s upper atmosphere – in 2021
- The mission objectives of the Parker Solar Probe are to study the structure and dynamics of the Sun's corona, the Sun's magnetic field, and the solar wind.

- Kessler Syndrome is a hypothetical scenario proposed by NASA scientist Donald J. Kessler in 1978 which predicts that when the density of objects in low Earth orbit (LEO)-roughly 100-1,200 miles above our planet reaches a certain critical level, it could lead to a chain reaction of collisions which could render the orbit unfit for human use and halt the space age.
