The INTERnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) is an ESA observatory scientific satellite which was successfully launched on the 17th of October 2002. The payload consists in four instruments : an optical camera (OMC), a X-ray monitor (XRM), an imager (IBIS) and a spectrometer (SPI). The spectrometer (20 keV-8 MeV energy range, 2.3 m high, 1.1 m diameter, around 1300 kg) has been supplied by CNES where this instrument has been managed, assembled and tested before delivery to ESA for satellite level activities. This paper describes the spectrometer flight model thermal design achieved thanks to the different international partners, gives and overview of the cryostat used to cool down the detection plane and exposes the thermal validation plan used at instrument level (thermal mathematical model and thermal test philosophy, cryostat thermal validation). We then focus on in-flight performances and compare them to expected ones.

ChemCam is one of the 10 instrument suites on the Mars Science Laboratory, a martian rover being built by Jet Propulsion Laboratory, for the next NASA mission to Mars (MSL 2009). ChemCam is an instrument package consisting of two remote sensing instruments: a Laser-Induced Breakdown Spectrometer (LIBS) and a Remote Micro-Imager (RMI). LIBS provides elemental compositions of rocks and soils, while the RMI places the LIBS analyses in their geomorphologic context. Both instruments rely on an autofocus capability to precisely focus on the chosen target, located at distances from the rover comprised between 1 and 9 m for LIBS, and 2 m and infinity for RMI. ChemCam will help determine which samples, within the vicinity of the MSL rover, are of sufficient interest to use the contact and in-situ instruments for further characterization.

COROT mission is managed by CNES (French National Space Agency) in association with three major French laboratories (LAM, LESIA, IAS) and several European countries, contributing to the payload and the ground segment. This astronomy mission objectives are astero-seismology as well as planet finding. The COROT spacecraft is based on a PROTEUS low Earth orbit recurrent platform, developed by CNES and Alcatel Alenia Space. It was injected on 27th December 2006 at a 898 km polar and circular orbit by a Soyuz launcher and is being operated from CNES-Toulouse. This paper focuses on the thermal control design and first in-orbit performances of the payload which mainly consists in an afocal telescope, a wide field camera with cooled CCDs, and an equipment bay. Largely using standard and well-proven technologies, this paper also points out some thermal control specificities and techniques used.
