Going Dark

The Hubble space telescope lost a key capalility recently.

The Hubble Space Telescope is flying partially blind across the heavens because of a short circuit in its most popular instrument, the advanced camera for surveys.

The story indicates that the capability was lost permanently, but this quote seems to indicate that a new camera being installed by an upcoming spacewalk could repace some of the functionality.

Adam Riess of space telescope institute, who has used Hubble to search for supernova explosions in the distant universe in order to gauge the effects of dark energy on cosmic history, said these explosions would now be out of reach until the new camera was installed.
