Hydra A is arguably the most spectacular nearby radio galaxy showing veryenergetic interaction of the radio jets with the embedding intracluster medium(ICM) of the A 780 host cluster. It has been the subject of several studiesrevealing many interesting features including signs of a precessing jet andmultiple radio outbursts. However, there are still crucial open questions. Wewant to improve our understanding of this benchmark system by studying theinteraction of the precessing jet with the ICM and by testing a new scenario ofmultiple radio outburst events. What is urgently needed are deeper X-rayspectro-imaging observations for the detailed diagnostics and modeling of theICM, which we propose here with a net XMM-Newton exposure of 312 ks.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
