The SPIRE collaborators in the MESS (Mass loss from Evolved StarS) GTKP wish to allocate 15 hours of SPIRE Guaranteed Time to enablethe acquisition of complementary 194-670um SPIRE FTS spectroscopy of 19 MESS evolved star targets for which PACS SED-mode 57-210um spectroscopy has already been obtained or scheduled. The original allocation of 80 hrs of SPIRE GT to the MESS programme for SPIRE imaging photometry and spectroscopy of evolved star targets, was sufficient only for FTS spectra to be obtained for 23 of the 51 evolved stars for which PACS GuaranteedTime was being used to acquire PACS SED-mode spectroscopy. The current application aims to remedy this situation, by obtaining complementary FTS spectra for most of the remaining targets that (a) have MESS PACS spectroscopy; (b) are bright enough for good S/N spectroscopy to be acquired at SPIRE wavelengths; (c) are not being observed with the FTS by any other Herschel programme.

Mission Description
Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
