NASA’s Parker Solar Probe has made history by becoming the closest human-made object to the Sun, flying a mere 3.8 million miles from its surface and sending back data indicating it is in good health.
Mission Overview
The Parker Solar Probe was launched on August 12, 2018, as a collaborative effort between NASA and Johns Hopkins Applied Physics Laboratory. The mission aims to study the corona, the Sun’s outer atmosphere, which is hotter than its surface by millions of degrees. To achieve this, the probe has undergone several close encounters with the Sun, with the latest one taking place on December 24th.
Closest Approach
The Parker Solar Probe flew within 3.8 million miles of the Sun’s surface at a speed of approximately 430,000 miles per hour. During this time, mission operations were out of contact with the probe due to its proximity to the Sun. However, NASA officials confirmed on December 26th that the probe had transmitted a signal back to Earth, indicating it was still operational.
Data Transmission and Analysis
The successful data transmission from the Parker Solar Probe is expected to provide valuable insights into the solar wind, heat, and energetic particles accelerated by the Sun. According to NASA, the close flyby will help scientists better understand how the corona gets so hot, a phenomenon that has puzzled researchers for decades.
Parker Solar Probe’s Heat Shield
To withstand the intense heat generated during its approach, the Parker Solar Probe is equipped with a Sun-facing heat shield that reaches temperatures of around 2,500 degrees Fahrenheit. In contrast, the probe itself maintains a relatively cool temperature of just 85 degrees Fahrenheit, thanks to its clever design and insulation.
