SOHO - Lost in Space! Updated!
News story originally written on July 17, 1998

Contact with the SOHO satellite has been lost for almost a month now. That means that the $1 billion craft is lost in space until we can regain contact with it! Engineers are trying to contact SOHO by sending commands to the spacecraft 12 hours out of every day.

Dr. George Withbroe, NASA's Director of the Sun-Earth Connections science program said, "In the last two years, SOHO revolutionized our understanding of the Sun in many ways. It was a unique set of instruments devoted to the study of the most important star to us on Earth -- our Sun -- and we are very hopeful that the project engineers will be able to return this world-class observatory to science operations again."

SOHO is a joint project of NASA and ESA. Its primary mission from 1995-1997 was very successful, but scientists are hoping to regain contact for the solar maximum season. Else, scientists will have to depend on spacecraft like ACE and Ulysses for solar coverage.
