“It will be the largest space observatory in history with an ultra-cool camera: the MIRI instrument.” who – which NASA books Recently on his Jet Propulsion Laboratory Twitter account. Leave it to Americans to draw attention to their science projects and inform the general public about them in an engaging way. However, it would have been close if the Mid-Infrared Instrument with that super-cold camera hadn’t come to fruition.

James Webb has become a very expensive project. It was once budgeted for a billion dollars, but it would eventually cost ten times as much. Logically, questions arise about costs: should they be expensive and complex? Does James Webb really need those four scientific instruments, namely the near-infrared camera, the near-infrared spectrometer, the mid-infrared instrument, the micro-guidance sensor/near-infrared imager and the non-slit spectrometer? Years ago, the United States focused mainly on Merry. A beautiful musical instrument, but is it really more than just “fun”? Eventually, the MIRI instrument also became part of the James Webb Telescope.
