September is Deaf Awareness Month! Here is a fun fact about the James Webb Space Telescope in American Sign Language, signed by NASA Goddard mission director Apurva Varia. Translation: "Webb’s mirror is coated in gold to optimize it for reflecting infrared light! The coating is so thin that a human hair is 1000 times thicker! It requires only about a golf ball's worth [mass] of gold to coat the huge primary mirror."
Note that we have added English closed captioning for those who don't read ASL - but please also note what a rich language ASL is. As a result the caption is not "word for word/sign," but it should still help guide the viewer in interpretation.
