Build Your Own James Webb Space Telescope! #1: An Overview of the Major Components
Introduction
After my recent post on what we expect to learn from the James Webb Space Telescope, I became interested in learning more about the space telescope. More specifically, I began reading about its components and how they operates as well as the specifications of the images it will be collecting.
I thought it would be fun to share what I have been learning with a series describing how the space telescope will operate. For the first article, I will be providing an overview on the JWST by summarizing its three elements.
The Integrated Science Instrument Module
The Integrated Science Instrument Module (SIM) consist of the four cameras in the telescope. Altogether, the SIM will be collecting light within the range of .6 and 28.3 microns. In the upcoming post we will be taking a look at each of the four camera separately, what each one will be observing and some simulated data from them!
Above is a diagram of the range different modes of each camera will be able to measure. Understanding the differences between them will be a major aspect of differentiating between the functionalities of the four cameras.
The Optical Telescope Element
Once we develop a better understanding for the cameras we will be ready to discuss the OTE in more detail.
Spacecraft Element
The Spacecraft Element makes up the bulk of the telescope and includes all of the steering and regulatory systems of the telescope. Once the telescope begins its observations, the spacecraft element will be needed for everything from communicate with us, monitoring its power supply, orientating the observatory, and maintaining a constant temperature for the observatory.
Once we start learning about the workings of the spacecraft element we will begin to develop an understanding for the processes going on within the telescope which make the whole thing possible.
