NASA's attempt to resurrect the Hubble Space Telescope hit a roadblock on Thursday, further delaying an attempt to resume its science observations.

Engineers successfully bypassed a faulty computer on Wednesday in order to wake an 18-year-old onboard spare from hibernation. But the telescope re-entered a standby, or "safe", mode on Thursday, when the telescope's science instruments were turned on for calibration.

Software on the telescope's Advanced Camera for Surveys (ACS), which until recently served as the telescope's main camera, detected an anomalously low voltage level in the ACS and shut off the instrument at about 1330 EDT (1830 GMT), NASA announced on Friday.
