Abstract	Although the supernova rate in the Milky Way is thought to be 3 per century,only two supernova remnants younger than 400 yr are known, Cas A and G1.9+0.4.Both these sources are X-ray synchrotron emitters, and in both these sourcesfreshly synthesized, radio-active Ti-44 has been detected. This year a new,small (1.6 arcmin) shell-type supernova remnant was discovered, G354.4+0.0,which is a good candidate to be the youngest supernova remnant in the Galaxy. Wepropose to observe G354.4+0.0 both with XMM-Newton, for detailed imagingspectroscopy, and with NuStar for characterizing the potential synchrotronemission and search for line emission caused by the decay of Ti-44 at 68 keV and78 keV.

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.
