What commenters say

• Building a second James Webb Space Telescope would be significantly cheaper than the first due to reduced research and development costs.
• The cost of building a second telescope would not be dramatically lower due to the high cost of testing and validation.
• Having a backup telescope would provide protection against failure and ensure continued scientific progress.
• The value of the telescope lies not in its lifespan, but in the scientific discoveries it enables, which could be transformative even if it only operates for a short time.
• The military spending is not an effective use of resources compared to scientific investments like the James Webb Space Telescope.
• The concept of economies of scale does not apply to complex, one-of-a-kind projects like the James Webb Space Telescope.
• The success of the James Webb Space Telescope demonstrates the importance of investing in scientific research and exploration.
• The telescope's relatively short planned lifespan is a deliberate design choice that allows for more advanced technology to be developed in the future.
