On the 2nd December 1995 the worlds flagship solar probe SOHO was launched on a journey of some 1.5million Km's sunwards of Earth to the Lagrangian point, from where it has been sending back a near constant stream of data on our nearest star the Sun and its environment. In 10 years it has revolutionised our ideas about the solar interior and solar atmosphere and the acceleration of the solar wind. Scientists gathered on the anniversary of the launch, at CCLRC Rutherford Appleton Laboratory, to celebrate the achievements of SOHO. Below we bring you a few selected movies.

Some amazing facts about 10 years of CDS
  • 10,000,000 exposures have been taken
  • 34,000 science studies have been run
  • 240,000 science fits files have been produced
  • 3,500 individual science plans have been made
  • 400,000 command blocks have been sent to CDS by the CDS ground system
  • 400GB of data sent back from CDS
  • 666 reviewed science papers published
    The mechanisms have performed:
  • 24,000,000 mirror steps
  • 7,000,000 slit steps
  • 24,000,000 instrument pointing movements
    and all with just one major service, and that was before launch

News: 24th November 2005
A CDS Intrument status page is now online.
The CDS User Guide has been updated with latest GIS information.

We still await the definative orbit information files. Processing of CDS final telemetry continues, though data sets are not being flagged as 'Final' until the orbit files becomes available. View the CD Processing page to see the current processing status
