More Problems With Hubble

Hubble’s resurrection is suspended while engineers examine two anomalies
Two anomalies onboard the orbiting Hubble Space Telescope, which stopped transmitting data on September 27, caused engineers to suspend re-activation of Hubble’s science equipment. Engineers encountered problems following an intricate maneuver to circumvent a piece of failed hardware. Hubble is currently orbiting Earth in a dormant “safe mode” while the malfunctions are assessed.

In an October 17 teleconference, NASA scientists said that it is too soon to know the details of the failures. “We are in the early stages of going through a mountain of data that has been downloaded,” said Art Whipple, manager of the Hubble Systems Management Office at NASA’s Goddard Space Flight Center in Greenbelt, Md., at the teleconference. “This is a marathon, not a sprint.”

These latest anomalies came at a critical time, during the team’s attempt on October 16 to wake up all of Hubble’s science equipment and restore the orbiting telescope to full science capabilities.

The late September failure in Hubble’s science data formatting unit halted all science data communications to Earth. Since then, Hubble has been orbiting Earth silently, performing only basic health and safety functions, with almost all of its science observations suspended.
