Measurements of the growth of cosmic structure, based on the number density andmass distribution of galaxy clusters as a function of redshift, place powerfulconstraints on cosmological models. As the only all-sky Sunyaev-Zel.dovich (SZ)selected cluster sample, Planck.s PSZ2 sample has a uniquely powerful role.Despite this, follow-up X-ray observations of the z>0.4 PSZ2 sample areincomplete, with archival coverage biased towards the X-ray brightest systems,which is problematic for most cosmological studies. Completing the X-rayfollow-up coverage, and thus providing low-scatter X-ray massproxies for every cluster at z>0.4, will enable significantly improved,more robust cosmological constraints to be obtained.

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.
