How NASA Built the Fastest Spacecraft Ever

Engineers and designers working on the Parker Solar Probe tackled challenges such as size, weight, and extreme heat. Their design combined unique materials and underwent rigorous testing to transform the Probe into a record-breaking spacecraft.

Why Won't Parker Solar Probe Melt?

"In space, the temperature can be thousands of degrees without providing significant heat to a given object or feeling hot. Why? Temperature measures how fast particles are moving, whereas heat measures the total amount of energy that they transfer. Particles may be moving fast (high temperature), but if there are very few of them, they won’t transfer much energy (low heat). Since space is mostly empty, there are very few particles that can transfer energy to the spacecraft."

Who is Eugene Parker?

"More than half a century later, the Parker Solar Probe mission will finally be able to provide key observations on Parker’s groundbreaking theories and ideas, which have informed a generation of scientists about solar physics and the magnetic fields around stars. Much of his pioneering work, which has been proven by subsequent spacecraft, defined a great deal of what we know about the how the sun–Earth system interacts."

"From Earth, we can only ever see the corona during a total solar eclipse, which is why it is incredibly difficult to study. Because the density is so low, the corona’s brightness is overpowered by energy coming from the solar surface. As the last layer of the sun’s atmosphere, the corona extends millions of miles into space. Here, temperatures can rise to over one million degrees Celsius which is about 300 times hotter than the photosphere, the lowest layer of the sun’s atmosphere."
