The structure of low-power radio galaxies is thought to be determined largely byinteractions with the group atmosphere in which these objects typically reside.Detailed observations of these atmospheres can answer long-standing questionsabout physical conditions in radio galaxies, their dynamics and evolution. OurXMM GO observations of two such objects provide strong evidence for theinfluence of environment on radio-lobe structure, illustrating that XMM.s highsensitivity to large-scale X-ray emission is ideally suited to this work. Wepropose to continue this observational programme by observing three morewell-studied twin-jet sources, enlarging our sample to include examples of alltypical FR-I radio-lobe morphologies.

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.
