The Hubble Space Telescope was originally scheduled for launch in 1986, was delayed by the events of January 28, 1986, was finally put in orbit in 1990, and went into full service after the 1993 mission to install corrective optics to compensate for an improperly-shaped main mirror. It has had several upgrade and repair missions since then, and is not quite dead yet. Its total cost, repair missions and all, is estimated at around $10 billion US. The James Webb Space telescope was initially scheduled to launch in 2007. The launch was delayed until 2011, then 2014, then 2018, then 2021. Its cost has been estimated at$10 billion US, and it's still not launched yet.

Because its planned deployment is at the Earth-Sun L2 Lagrange point, a million miles beyond Earth as seen by Mr. Sun, there will be no service missions. It will have to use fuel to maintain its position, and its fuel supply is expected to run out in ten years or so.
