Primary Science

The European Retrievable Carrier, or Eureca for short, was a satellite that carried 15 experiments including a number of experiments for microgravity studies, solar observations and material technology investigations.

High Energy Science

One of the expermiments in the Eureca payload was the Wide Angle Telescope for Cosmic Hard X-rays, or WATCH for short. WATCH was also flown on the Granat mission.

Science Highlights

  • Monitoring of two dozen known X-ray sources, some for over 100 days
  • Discovered a number of new X-ray transients
  • Detected 19 gamma-ray bursts, a dozen of those with localizations within a degree
