Answer:
The accident of the Columbia space shuttle made the repairs to the Hubble microscope uncertain, as well as the future of this telescope.
Explanation:
The Hubble telescope was a major scientific breakthrough, both in terms of its creation and its launch. It has been in space for over thirty years and there is no date for its shutdown.
This telescope needs maintenance in order to function effectively, however this maintenance has not been done for some time and it is uncertain when it will happen. This uncertainty is an effect that the Columbia space shuttle accident caused. That's because Columbia was responsible for maintaining Hubble, but it exploded when it returned to Earth, killing the entire crew. This made the telescope's repairs uncertain, expensive and dangerous, discouraging its execution.
