Scientists are eager to discover why the corona is far hotter than the Sun's surface and what accelerates the solar wind. They also hope to learn more about solar flares and coronal mass ejections (CMEs) and how they impact Earth and the rest of the solar system. The spacecraft's unique orbit and state-of-the-art instruments are key to achieving these ambitious goals. The probe uses a series of gravity assists from Venus to gradually shrink its orbit, bringing it closer to the Sun with each pass. This strategy allows the probe to gather data at different points in its orbit, providing a comprehensive view of the Sun's behavior.

The probe's journey involves a series of complex maneuvers, using Venus's gravity to change its orbit and get closer to the Sun. As the Parker Solar Probe's orbital distance decreases, it experiences increasing levels of solar radiation and heat. To survive in this extreme environment, the probe is equipped with a heat shield called the Thermal Protection System (TPS). The TPS is made of a carbon-composite material designed to withstand temperatures of up to 2,500 degrees Fahrenheit (1,377 degrees Celsius). Beyond the heat shield, the spacecraft's instruments are housed in a protected area to shield them from direct sunlight. This ingenious design is crucial for the mission's success, allowing the sensitive instruments to collect data without being destroyed by the Sun's intensity. In addition to the heat shield, the spacecraft has other advanced systems to manage the extreme conditions.
