Chapter 1: Parker Solar Probe's Historic Journey

NASA’s Parker Solar Probe has made headlines since the outset of its mission, claiming the title of the fastest spacecraft ever, surpassing the previous record held by the New Horizons probe. A few weeks into its mission, it achieved another milestone by flying through the sun's corona and transmitting invaluable data back to Earth. Recently, NASA announced that the probe has successfully completed a full orbit of the sun and is set to embark on its second journey.

The probe became fully operational on January 1, with all systems functioning smoothly. It has been transmitting vast amounts of data via the Deep Space Network, with over 17 gigabytes collected so far. Given the extensive data gathered, it will take several months to relay everything back to Earth, with the data from the first orbit expected to finish just as Parker prepares for its next dive into the sun's corona.

In anticipation of this upcoming solar encounter, NASA is diligently clearing space on Parker's internal solid-state drives. As data is sent back to Earth, corresponding files on the probe are deleted to ensure sufficient storage for new information. Each month, NASA transmits updated navigational data to the spacecraft.

Section 1.1: The Next Perihelion Approach

NASA anticipates that Parker will reach its perihelion, the point of closest approach to the sun, on April 4. This marks the second of 24 planned orbits designed to deepen our understanding of solar phenomena. The mission has been years in the making, as NASA has long sought to investigate the sun's corona. However, the technology to safeguard a probe during such extreme conditions has only recently become feasible.

It's a common misconception that the surface of the sun is hotter than the surrounding space, but in reality, the sun's corona, composed of ionized plasma, reaches temperatures around one million Kelvin—300 times hotter than the solar surface.

Section 1.2: Engineering Marvels

Parker is equipped with a 4.5-inch carbon composite foam heat shield, protected by two layers of carbon fiber. NASA had uncertainties about its performance until the probe entered the corona, but current assessments suggest that Parker will successfully complete all 24 orbits without succumbing to extreme heat.

The perihelion for the April orbit will be approximately 15 million miles (24.1 million kilometers) from the sun, bringing it slightly closer than during its previous orbit. With each pass, the probe will gradually approach the sun, eventually reaching within 3.8 million miles of its surface in the coming years.
