Washington: Engineers at NASA`s Goddard Space Flight Center in Greenbelt, Md., completed one of the most delicate performances of their lives and meticulously implanted part of the eyes of the James Webb Space Telescope.
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.
Disturbing MIRI would cost the mission the critical science that will help shape our knowledge of the universe, and push the boundaries of scientific discoveries. For that reason, precise engineering is key and that can put some of the engineers in awkward positions, literally.
Hylan said that, like watching the new World Trade Center being built in New York right now, the process is tedious, but the end result is something significant that will leave its mark on a generation.
The James Webb Space Telescope is the successor to NASA`s Hubble Space Telescope . It will be the most powerful space telescope ever built and observe the most distant objects in the universe, provide images of the first galaxies formed and see unexplored planets around distant stars.
The Webb telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.
