NASA plans to launch the first human probe, the Parker Solar Probe, to the sun on August 4th. The main purpose of this ambitious project called "Touch the Sun" is to study the solar wind. Parker Solar Detector first installed and deployed a cutting-edge Thermal Protection System on June 27. NASA recently revealed that its first installation was officially completed. This state-of-the-art thermal protection system will protect Parker Solar Detectors from harsh temperatures and cosmic environments up to 4 million miles from the sun.
In order to protect against high temperatures, engineers designed a special thermal protection system for Parker's solar detectors, including a carbon protective cover with a thickness of nearly 12 cm, like a thick parasol, covering the detector's main instruments in the shadows. The carbon shield can ensure that the core instruments are not affected. Its design can withstand temperatures up to 1370 ° C. NASA believes that the carbon shield can maintain the main instruments at the core at around 29.44 ° C, protecting the main instruments from high temperature damage. This is also the first time a thermal protection system has been formally installed on a Parker solar detector since testing began in 2017.
