NASA’s Parker Solar Probe, the first spacecraft to fly directly into the sun’s atmosphere, blasted off from Cape Canaveral Air Force Station on August 12, 2018. The probe was designed to study the mysteries of the sun and provide insights into its inner workings. In this article, we will delve deeper into the mission of the Parker Solar Probe.
The Parker Solar Probe is on a mission to study the sun’s corona, or outer atmosphere, to understand the physics behind the processes that cause coronal mass ejections and solar wind. The probe will also explore the solar wind, the stream of charged particles that flows out from the sun, and study the sun’s magnetic field. Scientists hope to gain new insights into phenomena such as the heating of the corona and the acceleration of solar energetic particles.
The Parker Solar Probe carries four suites of scientific instruments to measure the sun’s magnetic and electric fields, particles, and waves. The SWEAP (Solar Wind Electrons Alphas and Protons) instrument suite measures the hot plasma in the solar wind. The FIELDS (Electromagnetic Fields Investigations) suite measures electric and magnetic fields. The WISPR (Wide-field Imager for Solar Probe) camera captures images of the solar wind and the corona. The ISOIS (Integrated Science Investigation of the Sun) instrument suite measures the properties of ions and electrons that are emitted from the sun.
The Parker Solar Probe is subjected to extreme heat and radiation as it ventures closer to the sun. The temperatures in the corona can reach millions of degrees Celsius. To withstand these conditions, the probe is equipped with a heat shield made of carbon composite material that can withstand temperatures of up to 1,400 degrees Celsius. However, the heat shield will experience some erosion, and the probe may experience temporary communication blackouts as it passes behind the sun.
The Parker Solar Probe’s mission is expected to contribute to understanding the processes that govern the sun’s behavior. It will help us understand the sources of solar wind and how the sun’s magnetic field affects the solar system. The mission will also provide insights into space weather, which can affect spacecraft, communication systems, and even power grids on Earth. With this increased understanding, we can better predict space weather and mitigate its effects.
The launch of the Parker Solar Probe marks a significant event in the history of space exploration. As the probe begins its journey towards the sun, it offers an unprecedented opportunity to study the processes that power our star and affect the space environment around us. Scientists and researchers around the world eagerly await the data from the probe and the insights it will provide into the mysteries of our sun.
