The object that TMG >discovered is apparently coming into to view more and more. The orbit was >pegged by our members at 30-32 day. And here we are exactly 30 days later >and SOHO is shut down - and perhaps for good! Concerns: Is the shut down >just to keep certain of us under control? Are the objects a threat to the >Earth? Will there still be information on other sites (however we know that >the pics from SOHO/LASCO were the best)? > >We wanted to make you aware of this - you will likely know before the media >gets a hold of this story.

The Board acknowledges the outstanding achievements of the SOHO >>Recovery Team. >> >> 2. The spacecraft is operating in a sun pointing mode with all >>instruments on and collecting high quality science data. >> >> 3. Roll gyro redundancy has been lost, which increases the risk >>associated with recovery from future spacecraft anomalies. >> >> 4. The Board endorses implementation of several measures to increase >>ground syste effectiveness in order to reduce risk to operations. >> >> 5. Recommendations include a strengthened management structure and >>processes with increased staffing and includes a phased approach to >>transition to normal operations. >> >> 6. Implementation of the response to the recommendations will >>contribute significantly to the mitigation of risk of future operations >>and ensure the obligations of both agencies. >> >
