Detailed explanation-1: -After 20 Years of Construction, the James Webb Space Telescope Is Finally Complete.

Detailed explanation-2: -Thanks to the precision of the European Space Agency’s Ariane 5 rocket that launched JWST, NASA says the observatory will have enough fuel for at least 10 years of operations.

Detailed explanation-3: -Engineers and astronomers innovated new ways to meet the Webb telescope’s scientific demands, as well as a mission at an unserviceable distance from Earth. Unlike Hubble, astronauts will not be able to repair and upgrade the telescope. Construction on Webb began in 2004.

Detailed explanation-4: -Webb’s mission lifetime after launch is designed to be at least 5-1/2 years, and could last longer than 10 years. The lifetime is limited by the amount of fuel used for maintaining the orbit, and by the possibility that Webb’s components will degrade over time in the harsh environment of space.
