Art Poland, mission scientist for the Solar and Heliospheric Observatory, said Monday that radio contact with the craft -- which has already exceeded its two-year operational lifetime -- dropped out suddenly last week while it was going through an alignment procedure that involved firing control jets. ``We have had no communications with SOHO since last Thursday morning,'' said Poland. He said engineers have determined the craft is spinning and has lost its alignment with the sun. Exactly how it is spinning and the rate of spin is not clear, Poland said. ``We are not certain about what went wrong,'' said Poland. He said engineers are trying to restore the SOHO signal and to stabilize the craft, but added: ``There is a real fear that we won't get it back.'' European and American engineers are hoping that solar panels on the craft will generate enough power for the satellite to receive and act on stabilizing commands from the ground. Its battery holds only a one-hour charge. SOHO is a joint project of the National Aeronautics and Space Administration and the European Space Agency. NASA provided about $477 million of the total $1 billion cost of the craft, said Bill Steigerwald, a spokesman at the Goddard Space Flight Center. The satellite was designed for a two-year operational lifetime and was launched on Dec. 2, 1995. SOHO was placed in what is called the L-1 point, a position 1 million miles from the Earth that is gravitational neutral. Objects placed at such points tend to maintain the same Earth-sun position instead of orbiting around the Earth as do most satellites. Instruments on SOHO were able to take pictures of the sun in several different spectra, or light wavelengths. The satellite also could measure and analyze particles and magnetic fields generated by the sun. EOF How convenient ;) The attached photo is from the LASCO site. I did a screen shot as I closed the picture which tends to highlight prominent features in the picture. This is the sun on June 24, 1998. The other pictures from my cache have disappeared. Sue Kovios
