The James Webb Space Telescope (JWST) faced many tough obstacles during its development. Engineers worked hard to solve these problems.

1. Complicated Mirrors:

   • The JWST has a large mirror made up of 18 hexagon-shaped pieces. These pieces need to be perfectly lined up to make a clear picture. Doing this in space after the launch was really hard. If they weren’t lined up right, the telescope could fail.

2. Keeping It Cool:

   • Space is very cold, and it was important to keep the telescope at stable temperatures. If it got too hot, it could mess up the infrared images. Engineers created a sunshield that’s as big as a tennis court to block the sun’s heat. This took smart thinking and new materials.

3. Setting Up the Telescope:

   • Getting the telescope ready to work involves using more than 100 motors and pulleys. This made engineers worried about things breaking. They did a lot of tests, but it was hard to mimic the actual conditions in space.

4. Money and Time Issues:

   • The project often went over budget and took longer than planned. This made some people doubt if it would ever be finished. Engineers had to find ways to save money while coming up with new solutions. They also asked for more funding to deal with unexpected problems.

Even with these challenges, engineers kept changing their designs and testing methods. They used new technology and materials to make sure the JWST could reach its amazing goals.
