During routine maneuvers on Wednesday, 24 June, the Solar and Heliospheric Observatory (SOHO)--one of the most productive solar astronomy satellites ever--lost contact with Earth when a safeguard program kicked in unexpectedly, apparently sending the craft into a spin. The craft's high-gain communications antenna is no longer pointed toward Earth. Although communication should still be possible through two omnidirectional low-gain antennas, so far SOHO has not talked back.
