Much like the inside of an operating room, in the clean room at NASA’s Goddard Space Flight Center in Greenbelt, Md., engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their lives. That part of the eyes, the MIRI, or Mid-Infrared Instrument, will glimpse the formation of galaxies and see deeper into the universe than ever before.
It’s high-stakes surgery that has taken years of preparation. This science instrument must fit precisely into the ISIM, or Integrated Science Instrument Module (the black frame on the right to which they install the MIRI), so that it is installed exactly where it needs to be within the width of a thin human hair.
This intricate process involves a tremendous amount of work from the engineering team to make sure the instrument is settled and installed just right. The MIRI itself weighs 181 pounds (82 kg) and is being held by a crane (on the left of the photo), which is being maneuvered by the engineer at the base of the ladder. Each engineer has a role in the process that must be done as delicately as possible so as not to disturb anything, said Jason Hylan, the engineer responsible for the operation from start to finish.
