The development and deployment of JWST have not been without challenges. Some of these include:
Complexity and Cost: The telescope's intricate design and advanced technology have resulted in significant delays and budget overruns. Launch and Deployment: Unlike Hubble, which orbits close to Earth, JWST will be positioned at the Lagrange Point 2 (L2), approximately 1.5 million kilometers away. This makes on-site repairs impossible, so everything must work perfectly from the start. Thermal Stability: To observe in the infrared, JWST must operate at extremely low temperatures. Its sunshield is designed to keep the telescope cool by blocking heat from the Sun, Earth, and Moon.
