Is There Life After Hubble?
The arrival of Michael Griffin as new NASA administrator — along with his promise to reconsider the decision to cancel the space shuttle servicing mission to the Hubble Space Telescope once the shuttle starts flying again — makes the immediate future of space astronomy look suddenly much brighter.
Space astronomy’s long term, however, remains problematic. Even if a shuttle servicing mission upgrades Hubble successfully sometime around 2007, the most that mission can accomplish is to extend the orbiting observatory’s lifespan until about 2012. By then — if nothing else is done — the new gyroscopes will begin to fail and the world’s only optical space telescope will again approach the end of its life.
Worse, if the National Aeronautics and Space Administration launches and docks its planned de-orbiting module to Hubble following the shuttle repair mission, the module’s presence will make it impossible for any future servicing missions to dock with the spacecraft.
In other words, the de-orbiting mission — though guaranteeing a safe demise of Hubble — places a fixed and irrevocable death sentence on the iconic telescope.
