@JacksonBTT Splitting the sunshield into 5 layers allows heat to radiate out from between them, causing each successive layer to be cooler than the one below. The vacuum of space between each layer also acts as a great insulator. Learn more about the sunshield design: https://t.co/j1nRsAwHOL — PolitiTweet.org
