Abstract	The FIRST Flat Spectrum Sample (FFSS) is a deep radio-selected sample, unbiasedwith respect to X-ray emission. It is designed to enable us to determine thetrue census of the different types of blazars, resolving a long-standinguncertainty, and the first step towards understanding how Nature makes jets.This proposal aims to determine the type of FIRST blazars, which is easilydetermined from radio-optical-X-ray color and basic information about X-rayspectrum. We propose to obtain fluxes and hardness ratios for a subsample of theFFSS blazars, for which no X-ray information currently exists. With thisinformation we will be able to answer the key question: What kind of jets doesNature make?

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.
