NASA Analyzes Voltage Irregularities on Discovery

NASA space shuttle engineers are analyzing voltage irregularities encountered with the Discovery orbiter during launch preparations. The launch is currently scheduled for tomorrow, Wednesday, at 3:52 pm EDT. Mission managers will meet at 5:00 pm EDT today to discuss the issue.

According to NASA’s space shuttle website:

“During space shuttle main engine checkouts, the backup controller for engine 3 did not turn on as expected. There appeared to be an issue with one of three power phases, which was narrowed down to either a cockpit circuit breaker or switch that provides power. The circuit breaker and switch were turned off and on, restoring power.

“Engineers continue to analyze data that showed voltage irregularities and will meet this afternoon to review their data. The Mission Management Team now will convene at 5 p.m. EDT to assess the issue.”
