@scottparnapy @NASAWebb The sunshield will allow the telescope to cool down to a temperature below 50 Kelvin (-370°F, or -223°C) by passively radiating its heat into space. @NASAWebb’s MIRI instrument uses a cryocooler to reach its significantly lower operating temperatures of -447°F (7 kelvins). — PolitiTweet.org

What is special about this orbit is that it lets @NASAWebb stay in line with the Earth as it moves around the Sun. This allows the satellite's large sunshield to protect the telescope from the light and heat of the Sun and Earth (and Moon): https://t.co/rww0hBX9Ej — PolitiTweet.org
