The recently launched i James Webb Space Telescope (JWST) is the largest and most sensitive space telescope ever devised. It will replace the Hubble Space Telescope as the flagship space based observatory.



Between launch and deployment, the JWST must perform a bewildering array of tasks, many of them "single points of failure".

This is the first in a series of articles which will demonstrate why NASA engineers have the confidence that these tasks will all succeed.
There are a variety of ways in which engineers of all kinds, both space and DevOps/SRE, assure the success:

• Success assured via reliability.
• Success assured via redundancy.
  
• Success assured via repairability.
